Provided is a copolymer comprising from about 88 to about 92 mol % of a hydrophilic unit derived from N-vinylpyrrolidone and a cationic unit derived from a dimethyldiallylammonium salt, wherein the copolymer has a molar mass greater than or equal to 250,000 g/mol. Said copolymer is useful especially as a suds boosting polymer in hand dishwashing detergent compositions comprising a surfactant system, and provides improved foaming properties. |
