Skin treating cosmetic compositions containing N-polyhydroxyalkyl-amines

Claim 1

A cosmetic composition for maintaining or restoring a certain hygroscopicity in the skin for the protection of the skin of warm-blooded animals consisting essentially of an aqueous composition having a pH of between 5 and 7 and containing from 1 to 20% by weight of at least one N-polyhydroxyalkyl-amine compound selected from the group consisting of (1) amines of the formula ##STR13## wherein R 1 is a member selected from the group consisting of hydrogen, alkyl having from 1 to 18 carbon atoms, hydroxyalkyl having from 2 to 6 carbon atoms, dihydroxyalkyl having from 3 to 6 carbon atoms, trihydroxyalkyl having from 4 to 6 carbon atoms, and ##STR14## wherein R 6 and R 7 are members selected from the group consisting of hydrogen, alkyl having from 1 to 12 carbon atoms, hydroxyalkyl having from 1 to 3 carbon atoms, with the proviso that only one of R 6 and R 7 can be hydrogen, and, when taken together with the nitrogen, pyridyl, piperazino, morpholino, furfuryl, pyrrolidino and hydroxyalkylpiperazino having from 1 to 3 carbon atoms in the alkyl, and q is an integer from 1 to 3, R is the same as R 1 , with the proviso that only one of R and R 1 can be hydrogen, and R and R 1 together with the nitrogen, are alkylpiperazino having from 1 to 3 carbon atoms in the alkyl or hydroxyalkylpiperazino having from 1 to 3 carbon atoms in the alkyl, R 2 is a member selected from the group consisting of --CH 2 OH and --COOH, m is the integer 3 or 4, and n is the integer 0, or, when m is 3 and R 2 is --CH 2 OH, 1, and (2) physiologically-compatible acid addition salts thereof, and the remainder to 100% by weight of inert cosmetic excipients.
