Survey and Health Assement of the exposue of 2-year-olds to chemical substances in Consumer Product

6 Chemical analyses

6.1 Analyses

The purpose of the analysis in this project was to establish whether the product groups selected contained chemical substances that are potentially endocrine disruptors or allergens. The analysis programme consists of three elements: Screening analyses, quantitative analyses and migration analyses with different exposure scenarios.

The screening analyses were performed to identify the ingredients in the products selected. Further studies were performed on some of the products based on the results of the screening analyses. The product groups selected contained chemical substances that are potentially endocrine disruptors or allergens. Various exposure scenarios simulate contact with the skin and mouth using artificial sweat and saliva. Simulated inhalation was used to study release. The reasons for choosing these scenarios are described in Chapter 7.

Quantitative content analyses of selected substances and products were made to compare the total content of a product with that a child can be expected to be exposed to through contact with the product. The results were used to perform a risk assessment, including a comparison with previous quantitative studies that did not include exposure scenarios.

6.1.1 Product groups selected for analysis.

On the basis of the knowledge collected in Chapter 3 on previously studied substances and products, 12 product groups were selected for surveying.

The following 12 product groups were surveyed, see Chapter 3:

  1. Outdoor clothes in the form of jackets
  2. Outdoor clothes in the form of mittens
  3. Footwear in the form of rubber clogs.
  4. Footwear in the form of rubber boots (rubber boots).
  5. Pacifiers, primarily those in which the plastic part is made of polycarbonate.
  6. Bath soap packaging in which packaging is shaped as various figures and animals
  7. Non-slip figures and mats for bathtubs/showers
  8. Soft toys, including scented soft toys to be heated in a microwave oven
  9. Diapers
  10. Sunscreens
  11. Moisturising creams/oil-based creams/lotions
  12. Bed linen.

Of these 12 product groups, the following 10 were selected for analyses:

  1. Jackets
  2. Mittens
  3. Rubber clogs
  4. Unlined rubber boots
  5. Pacifiers, primarily those in which the plastic part is made of polycarbonate
  6. Bath soap packaging in which packaging is shaped as various figures and animals
  7. Non-slip figures and mats for bathtubs/showers
  8. Soft toys, including scented soft toyss to be heated in a microwave oven
  9. Diapers
  10. Bed linen.

Moisturising creams/oil-based creams/ lotions and sunscreens were not selected because, as agreed with DEPA, risk assessment was to be performed based on maximum permitted amount of the declared content of the products.

Each product group belongs to an arena of use, described in more detail in Chapter 3. Table 6.1 presents a list of the product groups by arena.

Table 6.1 Relationship between arenas of use and product groups analysed

Arena of use Product group
Good morning: Clothes Diapers
Good morning: Breakfast:  
Good day: Indoors play  
Good day: Playing outside Outdoor clothes, footwear, sunscreens
Good night: Bath Bath soap packaging, non-slip figures and bath mats, moisturising creams
Good night: Bed Pacifiers, bed linen, soft toys

Diapers fall into all arenas, which is to be expected as most 2-year-olds wear diapers day and night.

6.1.2 Analysis programme composition

The structure of the analysis programme is justified below. First an overall description is provided, followed by a summary of the conclusions of all analyses.

The product groups are described individually in the following chapters. The description includes methods and results of screening analyses, quantitative analyses and migration analyses, including reasons for selection of substances and products for more detailed studies.

A range of substances or substance groups have been selected and described in Chapter 3. Initially, there were more under consideration, but some were excluded. The analyses focused on the following substances and substance groups:

  • Bisphenol A, used for the production of certain plastic types, e.g. polycarbonate, and previously found in items such as baby bottles.
  • Phthalates, used as softeners, primarily in PVC.
  • Poly- and perfluorous compounds, which can be used in impregnating agents, and which were previously found in impregnated products.
  • Organotin compounds used as preservatives, biocides, and as a stabiliser in soft plastics. The substances were previously found in products in which odour problems were to be minimised, e.g. textiles.
  • Formaldehyde, used as a preservative, usually in cotton products stored and transported over long periods and under hot and humid conditions. Formaldehyde occurs most frequently in non-crease impregnated/non-iron-impregnated or printed textiles. Formaldehyde can also be found in adhesives, e.g. if a substance has a napped surface, or if decorative stones/glitter have been glued on.
  • Orthophenylphenol (OPP), used as a preservative and previously found in textile and paper products.
  • 2-mercaptobenzothiazole (MBT), typically used as an accelerator in the production of rubber.
  • Colofonium, a mixture of 3 resin acids, of which abietine acid comprises 90%. This substance has adhesive properties and is therefore used as an adhesive in many different products.

Table 6.2 presents the analysis methods used in the project.

The initial screening programme was based on knowledge from the survey as to which products could contain the substances. All the products selected were extracted with dichloromethane and analysed using GC/MS to determine the content of extractable organic substances.

In cases where the material composition is not stated on the product nor the accompanying packaging, and where the product was suspected of being made of polycarbonate or PVC, an FTIR analysis has been performed in order to determine the material type. The aim was to provide information to consumers on the relationship between material composition and the presence of bisphenol A and phthalates. The studies were not weighted, which gives the total material composition of the product.

  1. X-ray analyses are used to screen for fluoride. If fluoride can be identified by X-ray screening, there may be perfluoride compounds in the product. Extraction and GC/MS analysis confirm possible content by identification of the compounds and quantification. Similarly, information is obtained on other interesting elements such as bromine, which can reveal flame-retardants.
  2. ICP-MS is used to determine the total content of tin, which can indicate possible content of organotin compounds. In the event of positive findings, GC/MS is performed to confirm by identification of the compounds and quantification.
  3. GC/MS screening is used to investigate the content of bisphenol A, phthalates, OPP, MBT and colofonium plus other volatile and semi-volatile organic substances, e.g. perfume and aromatic compounds. GC/MS-screening was performed on all products and quantitative analysis on certain products for certain substances.
  4. Spectrophotometric analysis was used to identify formaldehyde.
  5. FTIR was used to determine material type in those products where such information was of interest and not declared on the product.
  6. Headspace analysis was used to identify volatile organic compounds released by the product when heated.
  7. SPME was used for quantitative determination from migration studies
  8. HPLC was used for quantitative determination of isocyanates from migration studies

The screening methods used are described under each product group, as there are variations between methods due to the different material composition of the products. Results and details of which part(s) of the products were used for analysis are also given under each product group.

Based on the results of the screening analyses, products and substances were selected for quantitative analyses and exposure scenarios. The grounds for such choices are given under each product group and described in more detail in Chapter 3.

The exposure scenarios used are described in the following section, whilst the methods of quantitative determination of migrating substances and results are given under each product group.

Section 6.11 contains a list of the results of quantitative analyses and results of the migration studies.

6.2 Exposure scenarios

Choice of relevant exposure scenarios was based on the possible use of the products by 2-year-olds. This project focused on skin contact (sweat) and mouth contact (saliva) plus inhalation of perfume and aromatic compounds where relevant.

The scenarios (including the simulant used and exposure time) were selected in consultation with DEPA. Further grounds and references concerning the exposure scenarios are given in Chapter 7, Table 7.1.

Analysis results are given under each product group in the following section and in Table 6.82. Risk assessment of the analysis results is given in Chapter 7.

6.2.1 Exposure scenarios

Table 6.3 describes the various exposure scenarios used in this project.

Table 6.3 Exposure scenarios used

Product Simulant Number hours per day Reason
Lining in outdoor clothes (jackets and mittens) Sweat 3 hours The child's skin can be in contact with the lining and the child can suck on the outside of the products. Children wear outdoor clothing when outdoors.
Outer material in outdoor clothes (jackets and mittens) Saliva 3 hours
Pacifiers (coverage) Saliva 7 hours, 45 minutes The child can hold a pacifier in its hand and suck/bite on the coverage. The child can use a pacifier at night, when taking a nap and for comfort.
Pacifiers (coverage) Sweat 7 hours, 45 minutes
Soap packaging Sweat 0.5 hours During bath time, the child can play and suck on the products.
Soap packaging Saliva 0.5 hours
Non-slip mats Sweat 0.5 hours The child sits on the product
Soft toys Inhalation 16 hours Soft toys can be used for play and comfort and when sleeping. This project also focused on soft toys containing perfume and aromatic compounds.
Bed linen Sweat 10 hours The child sleeps in bed linen at night when there is contact with the skin, including the face and hands.

Studies were made for certain substances deemed to be relevant to risk assessment.

6.2.2 Artificial sweat, saliva simulants and temperatures used

Simulants for sweat and saliva migrations were selected based on whether they had previously been used for comparable analyses of toys and textiles, for example. Furthermore, these migration fluids were selected because they only contain organic substances, and thus minimise the risk of interference of the organic substances being analysed.

The artificial sweat simulant used is described in DS/EN ISO 105-E04, as used for ØKO-TEX certification (Öko-Tex Standard 100). The sweat simulant in DS/EN ISO 105-E04 consists of 1-histidine-monohydrochloride-1-hydrate, sodium chloride, sodium dihydrogen phosphate, and sodium hydroxide for adjustment of pH to pH 5.5.

The artificial saliva simulant is described in an EU project (Simoneau et al, 20001 EUR 19826 EN). It consists of calcium chloride, magnesium chloride, potassium carbonate, potassium chloride, potassium phosphate, sodium chloride, and hydrochloric acid for adjustment of pH to pH 6.8.

The migration tests were performed at 37°C, which is close to body temperature and is used in DS/EN-71-3, DS/EN ISO 105-E04 and the aforementioned EU report. The simulant was heated before being applied to the products for the migration tests. The samples were placed in a temperature-controlled oven (37+/- 3°C) for the number of hours stated in the analysis programme.

Where sample quantity was sufficient, approx. 2.5 g material to 50 ml simulant was used, which is the amount used in DS/EN ISO 105-E04. The samples were cut into as few pieces as possible to maximally simulate use situations.

6.3 Outdoor clothes (jackets and mittens)

Outdoor clothing comes under the Good Day arena: Playing outside. The project focussed on outdoor clothes marketed as being waterproof, water resistant, or dirt resistant.

6.3.1 Summary of results

Screening the exterior part of the textile materials in the products provided evidence for the presence of a large number of organic substances. Some of these organic substances are suspected of being harmful or potential endocrine disruptors. For example, isocyanates (potential allergens) were found in several of the products. Migration studies on artificial saliva showed that only a fraction of the content migrates.

In addition to the product textiles, certain labels, straps and a reflector that were made of soft polymer materials and deemed to represent a risk of phthalate content, were selected for analysis for phthalates. Phthalates were found in labels printed with product names on two mittens, in a loose-hanging reflector and in a strap on a jacket zip.

To test for impregnating agents containing perfluoride compounds all the products were screened for fluoride. The analysis revealed fluoride in all of them apart from product nos. 1-4. Closer investigation of certain jackets and mittens revealed the content of various perfluoride compounds. It was not possible to perform migration studies on these substances.

Formaldehyde was found in the lining of all products. Migration studies of a mitten lining showed that a large proportion of the content migrated to artificial sweat.

6.3.2 Description of product type

Jackets and mittens consist of an inner part which can come in contact with the child's skin and an outer part, which the child can suck on. It was therefore deemed to be important that both the outside and inside of the products were tested. Products with straps attached to zips were of interest, as 2-year-olds tend to suck on the strap.

The project focussed on outdoor clothes marketed as being waterproof and/or water resistant. To achieve these properties, the clothes can have:

  • Impregnation on the outside
  • Plastic linings/coatings on the outside or inside.
  • Membranes on the rear or as a laminate in between the outer and inner materials.

Impregnation compounds can contain fluoride, but silicon compounds can also be used to provide a water resistant effect. The most common fluoride compounds used for this purpose are fluorocarbons, but fluorotelomers can also occur. It is also likely that membranes contain fluoropolymer compounds. Plastic linings can be polyurethane or polyvinylchloride and possible other types of polymers – it cannot be excluded that they can contain fluoride compounds.

6.3.4 Analyses methods

The following sections explain the screening methods and quantitative Analysis methods applied. The migration analyses have been carried out as described in Chapter 6.2, and have subsequently been analysed using quantitative analyses. The procedures are described below.

6.3.4.1 X-ray analysis

X-ray screening analyses (WEXRF) were performed on the outer material of jacket arms and mittens for elementary substances that could indicate impregnation using poly and perfluorinated compounds (Fluoride) and flame-inhibitors (Sb, Br).

6.3.4.2 GC/MS analysis, extractable organic substances

A GC/MS analysis is used to test for the presence of extractable volatile and semi-volatile organic components. The outer material and other textile parts that are easily accessible to the child were analysed, e.g. zip straps and Velcro tapes. If mittens were made of different materials on the back and palm, both were analysed. A single analysis was performed. The analysis method is described in Table 6.6.

Some jackets and mittens have labels, straps and reflectors easily accessible to the child, and made of soft polymer materials deemed to represent a risk of phthalate content. These parts were analysed quantitatively for phthalates. A single analysis was performed due to limited samples.

6.3.4.3 Spectrophotometer analysis of formaldehyde.

Spectrophotometer analysis was used to identify formaldehyde. The analysis was performed according to Japanese law no. 112 (1973). This determines the content of formaldehyde which is not bound. The result is quantitative. Dual analyses were performed on mittens, whereby the analysis was accredited. Single analyses were performed on jackets, whereby the analysis was not accredited. Priority was given to obtaining maximum knowledge of the product's formaldehyde content, as the jacket linings consisted of several different materials, making it relevant to take samples on several places on the product. The analysis method is described in Table 6.7.

Sweat migration was performed according the methods described in Chapter 6.2 Exposure scenarios for a set of bed linen and a mitten. The migration fluid was then analysed as described above, as extraction with water was avoided. A dual analysis was performed.

6.3.4.4 ICP-MS and GC/MS for organotin compounds

The products were analysed for organotin compounds using migration to artificial sweat. The sweat was then ICP-MS analysed to screen for tin content. In the event of positive findings, GC/MS was performed to identify and quantify the organic tin compounds (mono-, di- and tributyltin. A single analysis was performed.

The analysis method is described in Table 6.8.

Fluoride was found in all products except nos. 1-4. Further analyses were therefore performed to establish if the fluoride found came from impregnating agents containing fluorotelomers.

The presence of bromide and antimony could indicate that the products were impregnated with flame-retardants. However, the values are so low that they do not support this.

GC/MS analysis for organotin showed that there were no organotin compounds in the 3 products in which tin had been detected.

The analyses show that only a small number of the phthalates migrate from the products surveyed under the specified conditions. Formaldehyde, isocyanates, triphenylphosphate, diglycidylbisphenol and o-toluidine did not migrate. All products analysed contained perfluorinated compounds.

6.4 Footwear

Footwear comes under the arnea Good Day: Playing outside. The survey focused on rubber boots and rubber clogs.

6.4.1 Summary of results

In three of the five rubber clogs a quantifiable phthalate content was detected (product nos. 3-1, 3-3 and 3-4). Migration studies on artificial sweat showed that only a fraction of the phthalate content migrated from the products.

Only a few organic substances were found in the rubber boots, and one type of phthalate was found in one of the boots (product no. 4-4). Therefore, no further analyses were performed on these products.

6.4.2 Description of product type

The rubber clogs selected consist of the same material on the outside and inside. They are expected to be worn with socks, but can be used without resulting in skin contact.

Some of the boots consist of the same material on the outside and inside, whilst other products have a thin textile lining on the inside. Children were expected to have most skin contact with the upper edge of the boots analysed.

6.4.3 Selected products

Table 6.32 and Table 6.33 list the products selected for analysis. The reasons for choosing these products are described in the survey.

6.4.4 Analsyis methods

The following sections describe the screening methods and quantitative analysis methods used. The migration analyses have been carried out as described in Chapter 6.2 and have subsequently been analysed using quantitative analyses. The procedures are described below.

6.4.4.1
X-ray analysis

One of the products selected (product 4-2) had a textile edge at the top. This product was X-ray screened for fluoride to see if it had been impregnated with an agent containing per -or polyfluorous compounds. The analysis method is described in Table 6.34.

Table 6.34 X-ray analysis

Sampling Textile band at top of boot
Spectrophotometer ESEM, EDX
Detection threshold 0.1%
Analysis margin of uncertainty 5%*

*: Depends on concentration range

6.4.4.2 GC/MS analysis, extractable organic substances

A GC/MS analysis is used to test for the presence of extractable organic components. Samples were taken from the top edge of the boots or uppers of the rubber clogs. A single analysis was performed during the initial screening followed by a dual analysis for products selected for quantitative analyses. External standards were applied for calculating quantitative content of selected phthalates.

The analysis method is described in Table 6.35.

6.4.4.3 SPME analysis of migrating fluids

A 2.5 g sample (cut into as few pieces as possible and with the surface area estimated) was placed in 50 ml of preheated artificial sweat or saliva with BBP as internal standard and left at 37°C for 0.5-7.75 hours. The liquid phase was decanted from the sample pieces and examined using GC/MS, with solid-phase micro-extraction (SPME) of substances migrated to the liquid phase with 7 µm PDMS-fibre after the addition of 25% w/v NaCl.

6.4.5 Results

The results of the screening analyses are given in the sections below.

6.4.5.1 Results of X-ray analyses

No fluoride traces over 0.1% were found in the textile edge at the top of product 4.2, thus there is no evidence that this product had been impregnated with an agent containing per- or polyfluorous compounds.

6.4.5.2 Results of the GC/MS screening analyses

Table 6.36 and Table 6.37 contain the results of the GC/MS screening analysis. Results are given in units of µg/g. The results are semi-quantitative since the substances are estimated according to internal standards.

6.5.4 Analysis methods

The following sections describe the screening methods and quantitative analysis methods used. The migration analyses have been carried out as described in Chapter 6.2 and have subsequently been analysed using quantitative analyses. The procedures are described below.

6.5.4.1 FTIR analysis of the material composition

In the case of products 5-1 and 5-5, the material composition was not stated on the product nor on the accompanying packaging. Thus, a FTIR analysis has been performed in order to determine the type of material.

6.5.4.2 GC/MS screening, extractable organic substances

A GC/MS analysis is used to test for the presence of extractable organic components. All pacifiers were scalded with boiling water before analysis as agreed with DEPA, and as instructed on their user instructions (scalding or boiling). A sample was taken from the teat, along with a pooled sample of coverages. A single analysis was performed.

The analysis method is described in Table 6.41.

The coverages of all the pacifiers analysed were made of polycarbonate; they all contained bisphenol A. Phthalates were found in the coverage of two of the products, but in such low concentrations that the phthalates cannot have been added as softeners.

Pacifiers are defined as articles for infants as the product is intended to make it easier for the child to sleep or relax by sucking it. REACH, annex XVII, entry 51 and 52 continued the prohibition to use, import or sell toys and childcare articles containing certain phthalates (including DEHP and DINP) in concentrations above 0.1% expressed per mass of the softened material (equivalent to 1,000 µg/g, i.e. 1,000 ppm). This means that the DINP content in the coverage of pacifier 5-3 is above this limit. It may be that the coverage is not intended to be put in the mouth, but the pacifier can be turned the wrong way accidentally. The DEPA Chemical Inspection Service has considered the case.

6.5.6 Quantitative analyses and migration studies

6.5.6.1 Selection of products and substances

In collaboration with the Danish Environmental Protection Agency, a series of products and substances have been selected to undergo further investigations based on screening tests.

Despite high quantitative levels of phthalates and bisphenol A, the results show that these substances do not migrate with the use of artificial saliva or sweat for the stated number of hours.

6.6 Soap packaging

Soap packaging comes under the arena Good Night: Bath.

6.6.1 Summary of the results

All the soap packaging analysed was made of PVC and large quantities of phthalates were found in all the products analysed. The phthalates found were DEHP, DINP, DNOP and DEP. Migration studies showed that the some of the phthalates migrated to artificial sweat and saliva, whilst the heavier DINP did not.

All the soap packaging analysed contained DEHP, DINP and/or DNOP exceeding the permitted threshold of 0.1% in accordance with the statutory order on phthalates in toys (BEK 855, 2009). The Danish Safety Technology Authority subsequently determined that these products can be considered toys. Sales of these products were therefore stopped.

6.6.2 Description of product type

The products are shaped as colourful figures. They are soft products and focus was placed on the container, which represents the largest surface of the product. The packaging was rinsed thoroughly with water prior to analysis, but allowance has to be made for the contents of the product, e.g. perfume residue, that could affect the analysis results.

6.6.3 Selected products

Table 6.47 presents those products selected for analysis. The reason for choosing these products is described in the survey.

6.6.4 Analysis methods

The following sections describe the screening methods and quantitative analysis methods used. The migration analyses have been carried out as described in Chapter 6.2 and have subsequently been analysed as quantitative analyses. The procedure is described below.

6.6.4.1 FTIR analysis of the material composition

In cases where the material composition is not stated on the product nor on the accompanying packaging (products 6-2, 6-3, 6-4, 6-5), an FTIR analysis has been performed in order to determine the type of material.

6.6.4.2 GC/MS screening, extractable organic substances

A GC/MS analysis is used to test for the presence of extractable organic components. Samples have been taken from the product packaging (6-1: From the lid/head. From the rest a sample was extracted from the packaging, which includes valves). A single analysis was performed.

The analysis method is described in Table 6.48.

6.6.4.3 Quantitative SPME analysis of migrating fluids

A 2.5 g sample (cut into as few pieces as possible and with the surface area estimated) was placed in 50 ml of preheated artificial sweat or saliva with BBP as internal standard and left at 37 oC for 0.5-7.75 hours. The liquid phase was decanted from the sample pieces and examined using GC/MS, with solid-phase micro-extraction (SPME) of substances migrated to the liquid phase with 7 µm PDMS-fibre after the addition of 25% w/v NaCl.

6.6.5 Results

The results of the screening analyses are given in the sections below.

6.6.5.1 Results of FTIR analyses

The FTIR analyses showed that all the examined packagings (6-2, 6-3, 6-4, 6-5) consist of PVC softened with phthalates.

6.6.5.2 Results of the GC/MS-screening analyses

Table 6.49 presents the results of the GC/MS screening analysis Results are given in units of µg/g. The results are semi-quantitative since the substances are estimated according to internal standards.

n.d. means that the substance was not detected above the detection threshold.

Despite high quantitative levels in these projects, the results show that only a small amount of the phthalate contents migrates under the specified conditions. Results also show that the higher molecular weight phthalates DINP and DNOP are not detected in the migration fluids.

6.7 Non-slip figures and mats

Non-slip figures and mats for bathtubs belong to the arena “Go´nat”: Bath.

6.7.1 Summary of the results

The phthalates DEHP and DINP were detected in three of the products. Migration studies show that DEHP migrates to artificial sweat while DINP is not detected.

6.7.2 Description of product type

Non-slip figures and mats often consist of a smooth or structured surface and an underside with suction capabilities. When the child is sitting on the product, the greatest exposure will be from the top surface. However, when the child plays with the product, it may come into contact with both sides. Both sides of the product have been examined (at the edge).

6.8 Soft toys

Soft toys come under the arena Good Night: The bed

6.8.1 Summary of results

Two of the soft toys are designed for heating and they release several fragrances consistent with the constituents of lavender oil, both before and after heating. No fragrances were found in the remaining three products.

No trace of formaldehyde was found during analysis of the selected soft toys.

6.8.2 Description of product type

A soft toy may consist of many parts. For example, the fur, the eyes and the nose may be made from different materials such as textiles and polymers, and it may be equipped with a bowtie or be clothed. It was decided to pool the various materials used in the soft toys. Two of the selected soft toys are designed to be heated in the microwave and both these soft toys give off a lavender scent.

6.8.3 Selected products

6.8.4 Analysis methods

The following sections describe the screening methods and quantitative analyses used. Examination of exposure through inhalation is also conducted.

6.8.4.1 GC/MS screening, extractable organic substances

GC/MS is used to examine for organic components. Samples have been extracted from the surface of the soft toys (equal weight samples of each type of fabric on the soft toys). A single analysis was performed.

The analysis method is described in Table 6.58.

6.8.4.2 GC/MS-screening, headspace analysis

A GC/MS-headspace analysis is used to test for the presence of volatile organic components. The soft toys (the entire soft toy) are placed in a closed chamber (in an exsiccator) and volatile substances are then collected using Radiello-tubes (white diffusive body + cartridge code 130) for 16 hours with and without prior heating of the scented bears in the microwave (8-1 and 8-5 respectively). Microwave heating has been conducted according to the instructions on the soft toys, meaning that soft toy 8-1 (just the inside bag) was heated at 650 watts for 45 seconds. Soft toy 8-5 (the entire bear) was heated at 650 watts for 150 seconds. A single analysis was performed.

The analysis method is described in Table 6.59.

Two of the soft toys are designed for heating and these give off several fragrances, both before and after heating. No fragrances were found in the remaining three products.

6.8.5.3 Results of analyses for formaldehyde

Stuffing, bows, laces and pouch (depending on product) were analysed for formaldehyde, which was not detected above the detection threshold of 2 µg/g.

6.8.6 Quantitative analyses and migration studies

Headspace analyses were performed, which correspond to exposure through inhalation. The results can be found in section 6.8.5.2.

It was decided not to select more products and fabrics for further analysis in this product category.

6.9 Diapers

The diapers come under the arena Go´morgen: Clothing, but may come under all arenas if the 2-year-old child wears them for 24 hours a day.

6.9.1 Summary of the results

Screening analyses have been performed on the extractable organic compounds in various parts of the diapers. The analyses showed that most of the organic substances found are aliphatic hydrocarbons and polymers which could not be identified using the applied method.

Five of the organic compounds appear in all the products. These are all additives (antioxidants) which may have been used in the production of the polymers that comprise the diapers.

Limonene, which is a perfume substance, was detected in three of the products.

The analysis showed that three of the analysed diapers contained low levels of formaldehyde. However, these levels were so low that they were close to the detection threshold of this method.

No organotin compounds or rosin were detected in the diapers.

6.9.2 Description of product type

A diaper consists of many parts in close contact with the child’s skin. The filling material which provides suction capability is a large component of the product. The diapers’ upper edge and leg edges are also in close contact with the skin and may be made from a different material than the rest of the diaper in order to give a good fit. On selected diapers there is a strip of adhesive for fitting the diaper. This is not in direct contact with the skin.

6.9.4 Screening methods

In the following sections, the applied screening methods are explained.

6.9.4.1 GC/MS screening, extractable organic substances

A GC/MS analysis is used to test for the presence of extractable volatile and semi-volatile organic components. Samples have been extracted from the filling material, the elastic/rim around the legs, the waistband and, if present, frontal prints and adhesive strips. A single analysis was performed.

The analysis method is described in Table 6.65.

Table 6.65 GC/MS-screening

Sampling Samples were collected from 4-5 different places on the diapers.
The samples have been analysed individually.
Extraction Extraction agent: Dichloromethane and acetone (3:1), 20-40 ml.
Extraction: 60 min. in ultrasound followed by 60 min. of mechanical shaking
Internal standards DEHP-d4, Pyrene-d10, Naphthalene-d8.
GC/MS instrument Agilent GC/MS
GC parameters Column Phenomenex ZB-5 MS, 30 m x 0.5 mm id., 0.25 µm phase film
Carrier gas: Helium, constant flow at 1.9 ml/min.
Oven settings: 40 ºC for 0.5 min., 20 ºC/min. to 320 ºC for 15 mins.
Injection: 280 ºC, splitless
MS parameters Scan mode: 29-550 m/z
Solvent delay: 3 min.
Detection threshold 1 µg/g

6.9.4.2 GC/MS analysis, derivatised from rosin

5 ml of the extract from the GC/MS analysis was reduced to dryness after which 2 ml of BF3 in methanol was added. See Table 6.65 After heating, the sample was cooled and water plus hexane were added. The hexane phase was analysed using GC/MS using the same method as that for screening. Two samples were taken from each diaper, one from the filling and one from the inside lining. The detection threshold is estimated to be 1-2 µg/g.

6.9.4.3 Spectrophotometer analysis of formaldehyde.

A spectrophotometric analysis was employed for the identification of formaldehyde. The analysis was performed according to Japanese law no. 112 (1973). This determines the content of formaldehyde that is not fixed. The result is quantitative and a single analysis was performed. The analysis method is described in Table 6.66.

Table 6.66 Spectrophotometer analysis

Sampling  2.5 g
Extraction Japanese law no. 112 (1973)
Extracted at 40 °C using 100 ml water in 1 hour. Filter, add acetylacetone reagent and leave for 30 minutes in a water bath at 40 °C.
Spectrophotometer Absorption maximum 412-415 nm
Detection threshold 2 µg/g

6.9.4.4 ICP-MS for organotin compounds

The products were analysed for organotin compounds using migration to artificial sweat. The sweat was then ICP-MS analysed to screen for tin content. A positive finding meant that a GC/MS analysis was performed to identify and quantify the organotin compounds. A single analysis was performed.

The analysis method is described in table 6.67.

Table 6.67 ICP/MS-analysis

Sampling 2.5 g of filling material and elastic rim around legs

Detection threshold 0.03 µg/g for filling material and02 µg/g for elastic rim

6.9.5 Results

The results of the screening analyses are given in the sections below.

6.9.5.1 Results of GC/MS analyses

Several different parts of the diapers were analysed. Filling material, elastic leg rims, stretch closures, inner lining and imprints were all analysed.

GC/MS-analyses showed that most of the organic substances found are aliphatic hydrocarbons and polymers which could not be identified using the applied method.

Analysing the filling material of the diapers revealed no other organic substances in addition to those mentioned - except for Irganox 245 (an additive - antioxidant) found in product no. 9-2, see Table 6.68. The result is given in units of µg/g. The result is semi-quantitative since the substance is estimated according to an internal standard.

Five of the organic substances such as Irgafos 168 and BHT are present in all products. These substances are additives (antioxidants) which may have been used in the production of the polymers that are used in the diapers.

In three of the products the fragrance limonene was detected, although not in the filling material used for most of the diaper.

6.9.5.2 Results of analyses for rosin

An analysis was performed for rosin, which is sometimes used as an adhesive in paper products. No rosin was detected above the 2 µg/g detection threshold in the filling material of the diaper or in the waistband.

6.9.5.3 Results of analyses for formaldehyde

Table 6.74 presents the results of the spectrophotometric analysis for formaldehyde. Results are given in units of µg/g. The results are quantitative (single analysis) and state the content of free formaldehyde in the product. It was not possible to finish the analysis for the filling material in the diapers.

The diaper analyses showed that three diapers contained low levels of formaldehyde. However, these levels were so low they were close to the detection threshold of this method.

6.9.5.4 Results of analyses for organotin compounds

The diapers were analysed for organotin compunds by screening for tin. No tin was detected above the detection threshold (0.02-0.03 µg/g) in the diaper’s filling material, nor in the elastic bands near the legs.

6.9.6 Quantitative analyses and migration studies

In collaboration with the Danish Environmental Protection Agency, it was decided not to select any more products and fabrics for further analysis in this product category.

6.10 Bed linen

Bed linen comes under the arena Good Night: The bed

6.10.1 Summary of results

A large number of organic compounds have been detected in the examined bed linens; some will disappear after washing while others will remain detectable.

A number of substances suspected to be a health risk were detected in products no. 12-3 and 12-4, and which are subject to the requirements in the Eco-Tex Standard 100, such as dichlorobenzene, o-toluidine, aniline and dichloroanilines. The highest concentrations of organic substances were found in product no. 12-4.

At analysis of the bed linen, formaldehyde was detected in 3 types of bed linen. Contents decrease after washing. Product no. 12-4 has the highest detected levels both before and after washing.

6.10.2 Description of product type

One set of bed linen consists of a main pillowcase and a duvet cover. In this product, the sole focus has been on the duvet cover. All of the selected products are patterned, and the analyses have attempted to sample from as many of the colours as possible.

6.10.3 Selected products

Table 6.75 presents those products selected for analysis. The reason for choosing these products is described in the survey.

6.10.4 Washing procedure

All bed linens were analysed both before and after washing. Each set of bed linen was washed separately according to the instructions provided on the packing material or on the product, 60°C or 30°C, respectively. A standard washing procedure was performed in a washing machine of the brand Wascator, using a standard ECE-detergent without added perborate. No bulking agent was used and thus no standard wash fabric filling. “Blind-sample” washing was performed at 60°C, in which a 1 m cotton standardized fabric of full width (zig-zag cut at the ends) was washed by itself with ECE detergent. Both the blinded sample and the bed linen were then hung-dried.

6.10.5 Analysis methods

The following sections explain the screening methods and quantitative analysis methods used. The migration analyses have been carried out as described in Chapter 6.2 and have subsequently been analysed as quantitative analyses. The procedures are described below.

6.10.5.1 GC/MS screening, extractable organic substances

A GC/MS analysis is used to test for the presence of extractable volatile and semi-volatile organic components. Sampling of the bed linen was conducted in such a way that as many colours as possible were represented in the samples.

The analysis method is described in Table 6.76.

Table 6.76 GC/MS-screening

Sampling Between 1.0 – 1.3 grams extracted before and after washing

MS parameters Scan mode: 29-550 m/z
Solvent delay: 3 min.
Detection threshold 10 µg/g

6.10.5.2 Spectrophotometric analysis of formaldehyde

Spectrophotometric analysis was used to identify formaldehyde. The analysis was performed according to Japanese law no. 112 (1973) – this is an accredited method. This determines the content of formaldehyde, which is not fixed. The result is quantitative and dual analyses were performed. The analysis method is described in Table 6.77.

6.10.6 Results

The results of the screening analyses are given in the sections below.

6.10.6.1 Results of GC/MS analyses

Table 6.78 presents the results of the GC/MS analysis. The results are given in µg/g and are semi-quantitative since the substances are estimated according to internal standards.

Table 6.78 Results for the GC/MS-analyse, µg/g – before and after washing

Click here to see Table 6.78

A large number of organic compounds have been detected in the surveyed bed linens; some disappear on washing. A few substances appear in larger quantities after washing. The reason for this is that interfering substances made it impossible to identify those substances before washing. Some of these interfering substances are removed in the wash, resulting in better identification and quantification of other substances (semi quantitatively).

A number of substances were found in products no 12-3 and 12-4, including arylamines such as aniline, o-toluidine, dichloroanilines and dichlorobenzenes, which are regulated through the Eco-Tex Standard 100 (Eko-Tex Standard 100, 2009). The arylamines may be the decomposed products from an azo colouring agent and the dichlorobenzenes may result from chemicals used to aid fabric colouring. The highest concentrations of organic substances were found in product no. 12-4.

6.10.6.2 Results of analyses for formaldehyde

Tabel 6.79 presents the results of the spectrophotometric analysis for formaldehyde. Results are given in units of µg/g. The results are quantitative (average of dual analyses) and state the content of free formaldehyde in the product.

6.10.7.1 Selection of products and substances

A series of products and substances have been selected to undergo further examinations based on screening tests.

Table 6.80 Overview of selected products and substances

Product no. Description Components analysed for Analyses Reason
12-4 Bed linen, before washing Formaldehyde Sweat migration: 16 hours A quantitative result is found by extraction in water, 1 hour, 40 degrees. The child sleeps during the day and night.
12-4 Bed linen, after washing Formaldehyde Sweat migration: 10 hours In order to calculate exposure with and without washing

The set of bed linen containing the highest levels of formaldehyde during screening studies was selected for further analysis.

6.10.7.2 Results of quantitative and migration analyses

Results of the investigations are shown in the table below.

Table 6.81. Results of quantitative analyses and migration analyses for formaldehyde.

Product type + no. Quantitative analysis Migration analysis Migration period Migration fluid
Bed linen no. 12-4 before washing 182 ug/g 307 ug/g 10 hours Sweat
Bed linen no. 12-4 after washing 34 ug/g 121 ug/g 10 hours Sweat

A larger content of formaldehyde has been found following the migration analysis compared to the quantitative analysis using a standardized method for the detection of formaldehyde in fabric. The quantitative analysis is performed followed by 1 hour extraction with water, whereas the migration analysis is performed for 10 hours with artificial sweat, which is a watery fluid containing salts. It would therefore appear that the applied standardized method does not determine the total amount of formaldehyde present in a given product. The standardized method determines the amount of free formaldehyde, and it is possible that the artificial sweat releases more formaldehyde due to its composition, or due to the prolonged liquid exposure.

6.11 Overview of quantitative analyses and migration analyses

The results of the quantitative analyses and the migration studies are found in the chapters pertaining to the specific products. The most important results are summarized in Table 6.82.

n.a.: Product or fabric was not selected for analysis
n.s.: A screening result was not calculated
n.d.: The substance was not detected above the detection threshold, as indicated earlier in this report
n.p.: The analysis was not possible due to problems retrieving the frabrics

Substances and product groups have been selected based on these results, and subjected to risk assessment.

6.11.1 Conclusions from migration studies

The results from the migration studies are highly dependant on the substance in question:

  • A higher level of formaldehyde was detected in bed linen following migration over 10 hours compared to the quantitative analysis based on an extraction period of 1 hour.
  • Several products have high levels of phthalates, e.g. soap packaging, but only a fraction was found in the migration analysis. The high molecular weight phthalates (DINP and DNOP) were not detected by the migration analysis.
  • Bisphenol A was found in the coverage/button on pacifiers made of polycarbonate, but this was not detected by the migration analysis.
  • Perfluoro compounds were found in impregnated jackets and mittens, but migration analysis was not possible due to interference in the analysis method and thus poor detection. For this reason it cannot be determined - and thus not excluded - that perfluorate compounds migrate from the product.
  • Isocyanates (2,4-TDI and MDI), triphenylphosphate, Diglycidylbisphenol and o-toluidine, which were detected in jackets and bed linen, were all shown to migrate.

Risk assessment of selected substances is described in Chapter 7.
