Compositions for use as cosmetics

Abstract

Abstract The invention relates to new compositions to be used as cosmetics. The new cosmetics according to the invention contain as active agent 0.06 to 10% by weight of a reaction product of nicotinic acid, a nicotinic acid salt or a nicotinic acid halide and a polyhydroxy compound of the general formula (I), ##STR1## wherein n is an integer of 1 to 15 and R 1 and R 2 each stand for hydrogen, or R 2 represents hydrogen and R 1 is an alkyl group, or R 1 is hydroxyalkyl and R 2 is an alkyl group, or when n is equal to 1, R 1 and R 2 may also form together a group of the general formula --(CHOH) m --, wherein m is an integer of 1 to 4, or a group of the general formula --(CHOH) q --CHNH 2 --(CHOH) p --, wherein Q is an integer of 0 to 2 and p is an integer of 1 to 3, or R 1 may represent a group of the general formula --(CHOH) m --H, wherein m is an integer of 1 to 4, and at the same time R 2 stands for hydrogen. These active agents are either physiologically active or potentiate the biological effects of other physiologically active substances. The active agents exert beneficial effects in cosmetics, such as in liniments for stimulating scalp or hair bulbs, liniments against rheumatism, hair shampoos, etc. The active agents defined above are prepared by reacting a compound of the general formula (I) or a benzylidene derivative thereof with nicotinic acid, a nicotinic acid salt or a nicotinic acid halide.
