Abstract

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 C.sub.8-24 hydrophobic, preferably alkyl groups. Said quaternary ammonium group-containing monomer has the formula ##STR1## wherein R.sub.1 is H or CH.sub.3, R.sub.2 and R.sub.3 are independently C.sub.1-4 alkyls, PA1 R.sub.4 is C.sub.1-4 akyl, C.sub.2-3 hydroxyalkyl, or benzyl PA1 R.sub.2, R.sub.3 and R.sub.4 together contain less than 9 carbon atoms, PA1 Z is a water-solubilizing salt-forming anion, and PA1 M may be --CO--X--, then X is --O-- or --NR.sub.5 --, R.sub.5 is H or C.sub.1-4 alkyl and x is 1-6, or PA1 M may be phenylene then x is 1, said hydrophobic group-containing monomer has the formula ##STR2## wherein R.sub.1 is H or CH.sub.3, X is --O-- or --NR.sub.7 --, PA1 Y is --C.sub.2 H.sub.4 O-- or --…
