Abstract
An insoluble polyvalent salt of a C.sub.12 -C.sub.24 mono- or di-alkyl phosphoric acid is used as a lather controller in detergent compositions. The use of this material as lather controller is especially beneficial in built fabric washing detergent compositions.
Claims18
A solid detergent composition for fabric washing in water comprising about 1% to about 90% by weight of an anionic, nonionic, amphoteric or zwitterionic detergent active compound and about 0.05% to about 20% by weight of a polyvalent salt of an alkyl phosphoric acid having the general formula:
- ##STR2## where A is --OH or R.sub.2 O, n is 0 and R.sub.1 and R.sub.2 are the same or different C.sub.16-22 straight or branched chain, saturated or unsaturated alkyl groups, and containing about 0.05% to about 20% by weight of a mineral oil.
A lather control detergent additive for use in solid detergent compositions for aqueous fabric washing which comprises in substantially homogeneous admixture a polyvalent salt of an alkyl phosphoric acid having the general formula:
- ##STR3## where A is --OH or R.sub.2 O, and n is 0 and R.sub.1 and R.sub.2 are the same or different C.sub.16-22 straight or branched chain, saturated or unsaturated alkyl groups, and mineral oil, the ratio of the polyvalent salt of an alkyl phosphoric acid to the mineral oil being about 1:20 to about 10:1 parts by weight.
A process for forming a solid detergent composition for fabric washing in water according to claim 28, comprising forming a lather control detergent additive according to claim 11 and admixing the additive with an anionic, nonionic, zwitterionic or amphoteric detergent active compound.
