The present invention relates to compositions for the treatment of the skin containing from 1 to 20% by weight of a polyhydroxyalkylamine having the formula ##STR1## wherein R.sub.1 is a member having 3 to 6 carbon atoms selected from the group consisting of dihydroxyalkyl and trihydroxyalkyl, and R.sub.2 and R.sub.3 are members selected from the group consisting of hydrogen, alkyl having from 1 to 4 carbon atoms, hydroxyalkyl having from 2 to 4 carbon atoms and dihydroxyalkyl having from 3 to 4 carbon atoms, and salts thereof, and the remainder up to 100% by weight inert cosmetic excipients; as well as the method of skin treatment.

Process of skin treating with compositions containing

The present invention relates to N-polyhydroxyalkyl-amino acids of the formula ##STR1## wherein R.sub.1 represents a phenylene or a group of the general formula --CHR.sub.3 --, wherein R.sub.3 represents hydrogen, alkyl, benzyl possibly substituted by a hydroxyl group, hydroxyalkyl, mercaptoalkyl, methylthioalkyl, aminoalkyl, polyhydroxylalkylaminoalkyl, carboxyalkyl, guanidinoalkyl, N-polyhydroxyalkylguanidinoalkyl or a ureidoalkyl group, R.sub.2 represents a CH.sub.2 OH or COOH group, m stands for the integers of 3 or 4 and n for the integer 0, if m = 3, when R.sub.2 is COOH, or 4, or for the number 1, if m = 3 and R.sub.2 represents a CH.sub.2 OH group, their alkali metal salts or possibly substituted ammonium salts; as well as the process of preparing the same and skin care and protection agents containing an effective amount of said N-polyhydroxyalkyl-amino acids.

N-polyhydroxyalkyl-amino acids, their manufacture and skin treating

The present invention relates to compositions for the treatment of the skin containing up to 25% by weight of at least one N-polyhydroxyalkyl-amine of the formula ##STR1## wherein R.sub.1 is hydrogen, lower alkyl, hydroxy-lower alkyl or aminoalkyl, as well as heterocyclic aminoalkyl, R is the same as R.sub.1 except that both cannot be hydrogen at the same time, R.sub.2 is --CH.sub.2 OH or --COOH, m is the integer 3 or 4, and n is the integer O, or, when m is 3 and R.sub.2 is --CH.sub.2 OH, 1; and the method of skin treatment therewith.

Skin treating cosmetic compositions containing N-polyhydroxyalkyl-amines

Anti-inflammatory cyclic 2-furfural-acetals of the formula ##SPC1## In which X is hydrogen, a lower alkyl preferably having 1 to 4 carbon atoms, or nitro, Z is an alkylene of the formula
