Appendix 8: Calciumdodecylbenzenesulphonate (CaDBS) 
56     General description

56.1     Identity

Calciumdodecylbenzenesulfonate, CaDBS, is an anionic surfactant used as dispersing agent for pesticide formulation. It is often produced and used in a mixture of linear alkylbenzene sulfonates, LAS. Only very few data were found specifically on CaDBS.
