Abstract: Skin-care and skin-protection agents contain at least one polyethercarboxylic acid as a skin moisture-containing agent, and a process for treating skin comprises applying an effective amount of these agents to the skin.

Abstract: Skin-care and skin-protection agent compositions containing at least one aliphatic polycarboxylic acid, or a salt thereof, which may be substituted by sulfonate groups, as a skin moisture-retaining agent, as well as a process for protecting the skin utilizing this composition.

Abstract: 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.

Abstract: The present invention relates to compositions for the treatment of the skin containing up to 25% by weight of at least one polymer having carboxyl or carboxylate groups and hydroxyl groups of chiefly rectilinear or cross-linked C--C compounds, the ratio of carboxyl or carboxylate groups to hydroxyl groups in said polymer being in excess of 0.5:1, and particularly between 1.1:1 and 16:1, preferably between 2:1 and 9:1, and the polymerization degree being at least 3, preferably 3 to 300; as well as the method of skin treatment.

Abstract: 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.
