Abstract:
1. A method of treating a substrate selected from human skin, human hair and human nails, the method comprising applying to the substrate a thickened oil composition which is free of water and which comprises (1) an oil, and (2) dispersed in the oil, a side chain crystalline (SCC) polymer which the composition being at a temperature T (i) 70-99% by weight of repeating units derived from at least one n-alkyl acrylate or methacrylate ester in which the n-alkyl group contains 16 to 22 carbon atoms, (ii) 1-30% by weight of repeating units derived from at least one acrylate or methacrylate ester in which the ester group contains a hydroxyl-substituted alkyl group containing less than 12 carbon atoms, and (iii) 0-29% by weight of repeating units derived from at least one acrylate or methacrylate ester in which the ester group contains an unsubstituted alkyl group containing less than 16 carbon atoms.
