Use of a cationic polymer for improving sudsing profile of laundry detergent compositions is disclosed. The cationic polymer has a weight average molecular weight (Mw) ranging from 1,000 to 300,000 Daltons and contains: (i) from 35 mol% to 85 mol% of a first, nonionic structural unit derived from (meth) acrylamide (AAm); (ii) from 10 mol% to 65 mol% of a second, cationic structural unit; and (iii) from 0.1 mol% to 35 mol% of a third, anionic structural unit derived from (meth) acrylic acid (AA) or anhydride thereof, while the total mol% of (i) - (iii) adds up to 100 mol%, and the molar ratio of (ii) to (iii) is greater than 1. |
