Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
A foaming composition comprising (I) an alkylpolysaccharide surfactant having the formula RO(R 1 O) t (Z) x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is an alkyl, alkylphenyl, hydroxy alkylphenyl or hydroxyalkyl hydrophobic group or mixtures thereof in which said alkyl groups contain from about 8 to about 18 carbon atoms; R 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) a mixture of anionic cosurfactants neutralized with one or more cationic moieties consisting essentially of: (a) from about 1% to about 95% of a water soluble alkylbenzene sulfonate in which the alkyl group contains from about 10 to about 13 carbon atoms, and (b) from about 5% to about 99% of a cosurfactant selected from the group consisting of an alkyl glyceryl ether sulfonate in which the alkyl group contained from about 8 to about 18 carbon atoms, an alpha-olefin sulfonate in which the olefin group contains from about 10 to about 18 carbon atoms, an alkyl polyethoxylate carboxylate in which the alkyl group contains from about 10 to about 18 carbon atoms, and the polyethoxylate chain contains from about 2 to about 6 ethoxylate groups, and mixtures thereof.
Claim 2
Dependent Claim
221 words
A foaming composition comprising (I) an alkylpolysaccharide surfactant having the formula RO(R 1 O) t (Z) x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms and wherein R is an alkyl, alkylphenyl, hydroxy alkylphenyl or hydroxyalkyl hydrophobic group or mixtures thereof in which said alkyl groups contain from about 8 to about 18 carbon atoms; R 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) a mixture of anionic cosurfactants neutralized with one or more cationic moieties consisting essentially of: (a) from about 1% to about 95% of a water soluble alkylbenzene sulfonate in which the alkyl group contains from about 10 to about 13 carbon atoms, and (b) from about 5% to about 99% of a cosurfactant selected from the group consisting of an alkyl glyceryl ether sulfonate in which the alkyl group contained from about 8 to about 18 carbon atoms, an alpha-olefin sulfonate in which the olefin group contains from about 10 to about 18 carbon atoms, an alkyl polyethoxylate carboxylate in which the alkyl group contains from about 10 to about 18 carbon atoms, and the polyethoxylate chain contains from about 2 to about 6 ethoxylate groups, and mixtures thereof.
