Abstract
This invention relates to homogeneous liquid laundry detergent compositions containing polyhydroxy fatty acid amide, silicone antifoam composition, and anionic, nonionic or amphoteric surfactant. The silicone antifoam composition includes polyethylene glycol or a copolymer of polyethylene-polypropylene glycol having a solubility in water at room temperature of more than about 2 weight %.
Claims12
A homogenous liquid laundry detergent composition, comprising:
- a. from about 1 to about 30 weight % of polyhydroxy fatty acid amide having the formula ##STR5## wherein R.sup.1 is H, C.sub.1 to C.sub.4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl, or a mixture thereof, R.sup.2 is a C.sub.5 to C.sub.31 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected thereto, or an alkoxylated derivative thereof;
- b. from about 0.001 to about 1 weight % of silicone antifoam composition comprising by weight % of said antifoam composition:
- (1) from about 5% to about 50% of a polyorganosiloxane and a resinous siloxane or a silicone resin-producing silicone compound;
- (2) from about 0.1% to about 15% of a finely divided filler material, (3) from about 0.01% to about 5% of a catalyst to promote formation of silanolates;
- (4) from about 1% to about 40% of at least one nonionic silicone surfactant;
- and (5) from about 10% to about 80% of a copolymer of polyethylenepolypropylene glycol having a solubility in water at room temperature of more than about 2 weight %;
- and without polypropylene glycol;
- and
- c. from about I to about 50 weight % of anionic or amphoteric or additional nonionic surfactant.
A homogeneous liquid laundry detergent composition according to claim 8 wherein the nonionic surfactant is the condensation product of C.sub.10-20 alcohol and between about 2 and about 20 moles of ethylene oxide per mole of alcohol.
