Claims
- 1. In a method for keeping the skin of a warm-blooded animal moist comprising topically applying to the skin an effective moisturizing amount of a cosmetic composition,
- wherein the improvement comprises the cosmetic composition containing from 1 to 20 percent by weight, based upon the weight of the total cosmetic composition, of at least one skin moisturizing compound having the formula ##STR5## wherein R.sub.1 is a member selected from the group consisting of alkyl having 1 to 4 carbon atoms, alkylol having 2 to 4 carbon atoms, and alkyldiol having 3 to 4 carbon atoms, R.sub.2 is a hydroxyalkyl having 2 to 6 carbon atoms and having 1 to 5 hydroxyl groups, and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, and hydroxyalkyl having 2 to 4 carbon atoms.
- 2. The method of claim 1, wherein the cosmetic composition comprises from 3 to 10 percent by weight, based upon the weight of the total cosmetic composition, of at least one moisturizing compound.
- 3. The method of claim 1, wherein the pH value of the cosmetic composition is in the range of acid to neutral.
- 4. The method of claim 1, wherein the pH value of the cosmetic composition is about 6.
- 5. The method of claim 1, wherein the cosmetic composition contains conventional cosmetic excipients selected from the group consisting of an emulsifier, a fatty substance, a vegetable extract, a preservative, a perfume, a thickener, a solvent, a surfactant, and mixtures thereof.
- 6. The method of claim 1, wherein at least one skin moisturizing compound is selected from the group consisting of N-(2-hydroxyethyl)-carbamide acid-2-hydroxyethyl ester, N-(2-hydroxypropyl)-carbamide acid-2-hydroxyethyl ester, N-(1-hydroxy-2-methyl-2-propyl)-carbamide acid-2-hydroxyethyl ester, N-(2-hydroxyethyl)-carbamide acid-1-hydroxy-2-propyl ester, and N-(2-hydroxypropyl)-carbamide acid-1-hydroxy-2-propyl ester.
- 7. The method of claim 1, wherein the cosmetic composition is a foam bath.
- 8. In a method for keeping the skin of a warm-blooded animal moist comprising topically applying to the skin an effective moisturizing amount of a cosmetic composition,
- wherein the improvement comprises the cosmetic composition consisting essentially of an emulsion adjusted to a pH between 5 and 7 containing an emulsifier and from 1 to 20 percent by weight, based upon the weight of the total cosmetic composition, of at least one skin moisturizing compound having the formula ##STR6## wherein R.sub.1 is a member selected from the group consisting of alkyl having 1 to 4 carbon atoms, alkylol having 2 to 4 carbon atoms, and alkyldiol having 3 to 4 carbon atoms, R.sub.2 is a hydroxyalkyl having 2 to 6 carbon atoms and having 1 to 5 hydroxyl groups, and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, and hydroxyalkyl having 2 to 4 carbon atoms, said emulsion being an oil-in-water emulsion or water-in-oil emulsion.
- 9. In a method for keeping the skin of a warm-blooded animal moist comprising topically applying to the skin an effective moisturizing amount of a cosmetic composition,
- wherein the improvement comprises the cosmetic composition consisting essentially of a water and lower alcohol solution adjusted to a pH between 5 and 7 containing from 1 to 20 percent by weight, based upon the weight of the total cosmetic composition, of at least one skin moisturizing compound having the formula ##STR7## wherein R.sub.1 is a member selected from the group consisting of alkyl having 1 to 4 carbon atoms, alkylol having 2 to 4 carbon atoms, and alkyldiol having 3 to 4 carbon atoms, R.sub.2 is a hydroxyalkyl having 2 to 6 carbon atoms and having 1 to 5 hydroxyl groups, and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, and hydroxyalkyl having 2 to 4 carbon atoms.
- 10. In a method for keeping the skin of a warm-blooded animal moist comprising topically applying to the skin an effective moisturizing amount of a cosmetic composition,
- wherein the improvement comprises the cosmetic composition containing from 1 to 20 percent by weight, based upon the weight of the total composition, of at least one skin moisturizing compound having the formula ##STR8## wherein R.sub.4 is alkylene having 2 to 4 carbon atoms in its chain or alkylene having 2 to 4 carbon atoms in its chain which is substituted by lower alkyl, lower hydroxyalkyl or lower alkyl and lower hydroxyalkyl and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, and hydroxyalkyl having 2 to 4 carbon atoms.
- 11. The method of claim 10, wherein at least one skin moisturizing compound is selected from the group consisting of 4,4-dimethyl-oxazolidine-2-one, 4-hydroxy-methyl-4-methyl-oxazolidine-2-one, 4,4-bis-hydroxymethyl-oxazolidine-2-one, and N-(2-hydroxyethyl)-oxazolidine-2-one.
- 12. The method of claim 10, wherein the cosmetic composition consists essentially of an emulsion adjusted to a pH between 5 and 7 containing an emulsifier and from 1 to 20 percent by weight, based upon the weight of the total cosmetic composition, of at least one skin moisturizing compound having the formula ##STR9## wherein R.sub.4 is alkylene having 2 to 4 carbon atoms in its chain or alkylene having 2 to 4 carbon atoms in its chain which is substituted by lower alkyl, lower hydroxyalkyl or lower alkyl and lower hydroxyalkyl, and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, and hydroxyalkyl having 2 to 4 carbon atoms, said emulsion being an oil-in-water emulsion or water-in-oil emulsion.
- 13. The method of claim 10, wherein the cosmetic composition consists essentially of a water and lower alcohol solution adjusted to a pH between 5 and 7 containing from 1 to 20 percent by weight, based upon the weight of the total cosmetic composition, of at least one skin moisturizing compound having the formula ##STR10## wherein R.sub.4 is alkylene having 2 to 4 carbon atoms in its chain or alkylene having 2 to 4 carbon atoms in its chain which is substituted by lower alkyl, lower hydroxyalkyl or lower alkyl and lower hydroxyalkyl, and R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, and hydroxyalkyl having 2 to 4 carbon atoms.
