Skin cleaning- and protective agents are based on the usual components such as emulsifiers, fatty substances, vegetable extracts, solvents, perfumes, thickeners and preservatives, together with 1-20 wt. %, esp. 3-10 wt. % on total compsn. of N-hydroxyalkylsubstitued non-aromatic N-heterocyclic cpds. or their salts of formula (I):- (where R1 = 1-6C (di)hydroxyalkyl gp.; R2=1-4C alkylene chain opt. substd. by low alkyl, hydroxyalkyl, OH or carbonyl oxygen gps., R3 = direct bond or as R2 and X = O, imino gp., which is opt. substd. by 1-6C (di)hydroxyalkyl gp., or a methylene gp., such that R2, R3, X and the N atom form a 5- or 6- ring). (I) act as moisture-retaining agents and maintain or replace moisture lost from the skin due to environmental effects. |
