Method of moisturizing the skin with carbamide acid esters

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.

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.

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.
