Abstract
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 1 is a member having 3 to 6 carbon atoms selected from the group consisting of dihydroxyalkyl and trihydroxyalkyl, and R 2 and R 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A process for maintaining or restoring hygroscopicity in the skin for the protection of the skin of warm-blooded animals comprising topically applying to the skin a safe but effective amount as a moisturizing agent of a cosmetic composition consisting essentially of an aqueous medium adjusted to a pH between 5 and 7 containing from 1 to 20% by weight of at least one hydroxyalkylamine selected from the group consisting of (1) compounds having the formula ##STR5## wherein R 1 is a member having from 3 to 6 carbon atoms selected from the group consisting of dihydroxyalkyl and trihydroxyalkyl, and R 2 and R 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 (2) topically-inert acid salts thereof; and the remainder to 100% by weight of inert cosmetic excipients.
Claim 2
Dependent Claim
155 words
A process for maintaining or restoring hygroscopicity in the skin for the protection of the skin of warm-blooded animals comprising topically applying to the skin a safe but effective amount as a moisturizing agent of a cosmetic composition consisting essentially of an aqueous medium adjusted to a pH between 5 and 7 containing from 1 to 20% by weight of at least one hydroxyalkylamine selected from the group consisting of (1) compounds having the formula ##STR5## wherein R 1 is a member having from 3 to 6 carbon atoms selected from the group consisting of dihydroxyalkyl and trihydroxyalkyl, and R 2 and R 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 (2) topically-inert acid salts thereof; and the remainder to 100% by weight of inert cosmetic excipients.
Claim 3
Dependent Claim
10 words
The process of claim 1 wherein the pH is 6.
Claim 4
Dependent Claim
23 words
The process of claim 1 wherein said at least one polyhydroxyalkylamine is present in an amount of from 3 to 10% by weight.
Claim 5
Dependent Claim
18 words
The process of claim 1 wherein said at least one polyhydroxyalkylamine is present as said topically-inert acid salt.
Claim 6
Dependent Claim
42 words
The process of claim 4 wherein said topically-inert acid salt is selected from the group consisting of the halide, the sulfate, the phosphate, the acetate, the lactate, the tartarate, the citrate, the glycolate, the oxalate, the fumarate, the succinate, and the malate.
Claim 7
Dependent Claim
13 words
The process of claim 4 wherein said topically-inert acid salt is the chloride.
