A foaming light duty aqueous liquid detergent composition especially useful for hand dishwashing containing 5 to 50 wt. % of non-cationic detergent active material, optional foam boosters and hydrotropes, and 0.1 to 10 wt. % of a cationic foam-stabilizing copolymer containing a major weight proportion of units derived from acrylamide and/or methacrylamide, about 0.5 to 2 wt. % of quaternary nitrogen as present in quaternary ammonium groups, and about 0.1 to 10 wt. % of pendant C8-24 hydrophobic, preferably alkyl groups. Said quaternary ammonium group-containing monomer has the formula <IMAGE> wherein R1 is H or CH3, R2 and R3 are independently C1-4 alkyls, R4 is C1-4 akyl, C2-3 hydroxyalkyl, or benzyl R2, R3 and R4 together contain less than 9 carbon atoms, Z is a water-solubilizing salt-forming anion, and M may be -CO-X-, then X is -O- or -NR5-, R5 is H or C1-4 alkyl and x is 1-6, or M may be phenylene then x is 1, said hydrophobic group-containing monomer has the formula <IMAGE> wherein R1 is H or CH3, X is -O- or -NR7-, Y is -C2H4O- or -C3H7O-, Y is 0-60, when X is -O-, R6 is C8-24 hydrocarbyl, and when X is -NR7-, R6 is C1-24 hydrocarbyl and R7 is H or C1-24 hydrocarbyl, at least one of R6 and R7 being C8-24 hydrocarbyl. |
