Claim 1
Independent Claim
281 words
A foaming composition comprising (1) an alkylpolysaccharide surfactant having the formula wherein Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms; R is a hydrophobic group selected from the group consisting of alkyl, alkyl phenyl groups and mixtures thereof in which said alkyl groups contain from 8 to 18 carbon atoms; said alkyl group being either saturated or unsaturated and containing from 0 to 3 hydroxy groups, R 1 is ethylene, propylene and/or glyceryl, t is from 0 to 30; and x is a number from 1.5 to 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 weight ratio of (2) to (1) being from 1:10 to 10:1; and (3) from 2% to 10% by weight of an auxiliary foam booster selected from the group consisting of: (a) amides having the formula wherein R 7 is an alkyl group containing from 8 to 18 carbon atoms and each R 8 is the same or different and is selected from the group consisting of hydrogen, C l - 3 alkyl, C ' - 3 alkanol, and ―(C 2 H 4 O―) 1-4 H groups and mixtures thereof; (b) amines oxides having the formula wherein R 4 is an alkyl group containing from 8 to 18 carbon atoms, each R 5 is ethylene or propylene, b is from 0 to 30, each R is the same or different and is selected from the group consisting of C 1-3 alkyl, C l - 3 alkanol, and ―(C 2 H 4 O) 1-6 H groups and mixtures thereof; and (c) mixtures thereof.
