Abstract
An aqueous based structured Heavy duty liquid detergent formulation is disclosed, which contains selected bleaches, surfactant combinations, borate polyol pH jump systems, and selected decoupling polymers.
Claims2
A structured aqueous heavy duty liquid cleaning composition concentrate comprising:
- (1) about 1 to 40% by weight of the concentrate of a solid, particulate, substantially water-insoluble organic peroxy acid;
- (2) about 10 to 50% by weight of the concentrate of a surfactant;
- (3) about 1 to 40% by weight of the concentrate of a pH adjusting system which produces a pH in the concentrated composition of about 3-6 and upon dilution of the concentrated composition produces a dilute solution pH of about 7-9;
- (4) from 0.1 to 5% of the concentrate of a stability enhancing polymer which is a copolymer of a hydrophilic and a hydrophobic monomer, said hydrophilic monomer being selected from the group consisting of the acid or salt derivatives of maleic anhydride, acrylic acid, methacrylic acid and analogues or acrylic acid where the carboxylate group is replaced by anionic moieties selected from the group consisting of sulfonate, sulfate, phosphonate and mixtures thereof;
- said hydrophobic monomer being a hydrophilic monomer functionalized with a hydrophobic moiety selected from the group consisting of fatty amides, fatty esters, fatty alkoxylates, C.sub.8-22 alkyls, alkylaryls and mixtures thereof or a C.sub.8-22 alkyl or alkylaryl chain formed by reaction with an .alpha. olefin.
