Abstract
A light-duty liquid detergent and shampoo are provided containing an alkyl-polysaccharide surfactant and an anionic cosurfactant in certain proportion ratios. The light-duty liquid detergent also contains C.sub.1-3 alkanols, C.sub.1-3 alkanolamines, C.sub.2-4 polyols or mixtures thereof as a solvent component and water. The shampoo also contains an alkanol amide, a polymeric thickener and water.
Claims12
A light-duty liquid detergent composition comprising:
- (A) from about 5% to about 50% of a foaming composition comprising
- (1) an alkylpolysaccharide surfactant having the formula RO(R.sup.1 O).sub.t (Z).sub.x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is a hydrophobic group selected from the group consisting of alkyl, alkylphenyl, hydroxyalkylphenyl, hydroxyalkyl groups and mixtures thereof in which said alkyl groups contain from about 8 to about 20 carbon atoms;
- R.sup.1 contains from 2 to about 4 carbon atoms;
- t is from 0 to about 30;
- and x is a number from about 1.5 to about 10;
- (2) an anionic cosurfactant selected from the group consisting of sulfates, sulfonates, carboxylates and mixtures thereof, neutralized with one or more cationic moieties,
- the ratio of (2) to (1) being from about 1:10 to about 10:1 except that when the cosurfactant is an alkylbenzene sulfonate, the ratio of (2) to (1) is at least about 1:2, and when the cosurfactant is soap the ratio of (2) to (1) is at least about 1:2, and when the anionic cosurfactant does not contain a sulfonate or carboxylate x must be from 1.5 to 3 and the alkylpolysaccharide surfactant must have a free fatty alcohol content of less than about 2% by weight;
- (B) from about 1% to about 50% of a solvent selected from the group consisting of C.sub.1-3 alkanols, C.sub.1-3 alkanolamines, C.sub.2-4 polyols, and mixtures thereof, and (C) the balance water.
