Abstract
Hair treatment compositions are provided which have conditioning benefits and which contain a fatty acid polyester of a polyol selected from cyclic polyols, sugar derivatives and mixtures thereof, in which at least 50% by weight of the total fatty acid moieties of the polyester are C20 or higher unsaturated fatty acid moieties. Specific examples of suitable fatty acid polyesters are sucrose trierucate, sucrose pentaerucate, sucrose tetraerucate, sucrose trirapeate, sucrose tetrarapeate, and sucrose pentarapeate, and mixtures thereof. The compositions are typically in the form of shampoos or conditioners and give surprisingly improved overall conditioning, in particular hair softness.
