DESCRIPTION

CADDBS is a calcium salt of a linear alkyl benzene sulphonate salt in isobutanol. It is an
emulsifying and dispersing agent; it is used for the preparation of emulsifiable concentrate pesticide
formulations. It may be incorporated into a formulation on its own or as a mixture with solvents or other
surfactants. Normally, it is applied as a mixture with non-ionic, such as nonylphenol ethoxylates, tristyryl
phenol derivatives or castor oil ethoxylates.
