An aqueous skin wash composition comprising from 0.1% to 10% w/w of an α-hydroxy acid or an acid selected from salicylic, maleic and pyruvic acid, and an amount of a detergent base in an amount not exceeding 30% w/w wherein the detergent base consists of a mixture of an amount of a non-ionic alkylpolyglucoside surfactant not exceeding 20% w/w and an amount of amphoteric surfactant not exceeding 10% w/w, and a hydroxy-terminated urethane polymer of the formula:
- wherein:
- R and R1 are independently selected from an alkylene or alkenylene radical having from 1 to 20 carbon atoms, or a cycloalkylene or cycloalkenylene radical containing from 5 to 10 carbon atoms, or a mononuclear or fused ring arylene radical containing from 6 to 10 carbon atoms;
- R2 is selected from hydrogen, methyl or ethyl group;
- m is a number in the range 0 to 6;
- and n is an integer in the range 8 to 51,
- and wherein the pH of the composition is in the range 3.0 to 4.5.
