NEW COPOLYMERS USEFUL IN LIQUID DETERGENT COMPOSITIONS

摘要

The present invention relates to a copolymer comprising from about 71 to about 89 mol % of a hydrophilic unit derived from N-vinylpyrrolidone and a cationic unit derived from a dimethyldiallylammonium salt. The copolymer of the invention is useful especially as a sudsboosting polymer in hand dishwashing detergent compositions comprising a surfactant system. The copolymer of the invention provides improved foaming properties,and in particular may boost the suds, when added onto such handdishwashing detergent compositions.
