Foaming dishwashing liquid compositions

Claim 1

A foaming composition comprising (1) an alkylpolysaccharide surfactant having the formula RO(R'0).Z, 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 group 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; and (2) a mixture of anionic cosurfactants neutralized with one or more cationic moieties consisting essentially of: (a) from 1 % to 95% by weight, of a water-soluble alkylbenzene sulfonate in which the alkyl group contains from 10 to 13 carbon atoms, and (b) from 5% to 99% by weight, of a cosurfactant selected from the group consisting of an alkyl glyceryl ether sulfonate in which the alkyl group contains from 8 to 18 carbon atoms, an alphaolefin sulfonate in which the olefin group contains from 10 to 18 carbon atoms, an alkyl polyethoxylate carboxylate in which the alkyl group contains from 10 to 18 carbon atoms, and the polyethoxylate chain contains from 2 to 6 ethoxylate groups, and mixtures thereof.
