Polymeric skin-protecting cpds contain at least two polar gps. sepd by a predominantly a chain of at least 15C contg. a =5C cyclic residue. Preferred cpds and (A) polymers derived from 2-4 monomeric fatty acids with 2-4 CO2H or other polar gpds. (B) esters and polyesters of cycloaliphatic or aromatic polycarboxylic acids with at least one (5-7C) ring and polyoxyalkylene ethers with (2-30) oxyalkylene units contg. (2-4C) alkylene gps. (C) condensation products of (2-4C) epoxyalkanes with polyamines contg. 2-4 amino gps. and with (2-8C) in each aliphatic, cycloaliphatic or aromatic residue. (D) condensation products of epoxyethanes and an epoxypropane-propylene glycol starter of formula: HO(CH2CH2O)a(CHMe.CH2O)b(CH2CH2O)cH, where a = 1-150, b = 15-70 and c = 1-150. (E) esters and polyesters of polymerised fatty acids (as defined in (A) with polyols of type. a) polyoxyalkylene ethers with (2-30) oxyalkylene units with (2-4C) alkylene gps and b) condensation products are defined in C and D above. Esp. preferred are dimeric acids esterified with oxyalkylene polyols.
