Foam enhancing agent for light duty detergent

Claim 1

A light duty, liquid detergent composition in an aqueous solution consisting essentially of: (a) 0.1% to 1.0% by weight of a nonionic hydroxypropyl guar gum derivative; and (b) a ternary mixture of a water-soluble salt of an anionic C 8 -C 18 alkyl ethenoxy ether sulfate containing 1 to 12 ethenoxy groups in the molecule, a water-soluble salt of a C 8 -C 18 alkyl sulfate surfactant, the weight ratio of said alkyl sulfate to said alkyl ethenoxy ether sulfate being from 1:29 to 29:1, and a zwitterionic betaine surfactant of the formula: ##STR3## wherein R 1 is an alkyl group having 10 to 20 carbon atoms or the amido radical ##STR4## wherein R is an alkyl group having 9 to 19 carbon atoms and a is an integer from 1 to 4; R 2 and R 3 are C 1 -C 3 alkyl; and R 4 is an alkylene or hydroxyalkylene group having 1 to 4 carbon atoms, said ternary mixture being present in an amount of approximately 20% to 40% by weight of the composition with said betaine constituting 2% to 5% by weight of the composition, said composition having a viscosity of from at least 100 cps. to 1000 cps. at room temperature and exhibiting enhanced foaming properties as compared with the same composition without said nonionic guar gum.
