Abstract

Skin darkening compositions are made by dissolving cuprous chloride and either benzyl alcohol or 2,3-dihydroxybenzoic acid in an aqueous dermatologic base.

Claims

1. A skin coloring composition comprising an aqueous dermatologic base containing cuprous chloride and a member of the group consisting of benzyl alcohol and 2,3-dihydroxybenzoic acid, the concentration of said member in water being from 2 percent to 4 percent by volume and of said cuprous chloride in water being from 0.045 percent to 0.09 percent by weight.

2. A composition as described in claim 1 and including a sunscreen, the concentration of said sunscreen being from 0.1 percent to 3.0 percent by weight.

3. A composition as described in claim 1 in which said aqueous dermatologic base is saturated with said cuprous chloride and with said member of the group consisting of benzyl alcohol and 2,3-dihydroxybenzoic acid.

4. A composition as described in claim 1 and including a surfactant, the concentration of said surfactant being from 0.05 percent to 1.0 percent by weight.

5. A method of coloring skin comprising the application of an aqueous dermatologic base containing cuprous chloride and a member of the group consisting of benzyl alcohol and 2,3-dihydroxybenzoic acid, the concentration of said member in water being from 2 percent to 4 percent by volume and of said cuprous chloride to water being from 0.045 percent to 0.09 percent by weight.

6. A method as described in claim 5 in which said aqueous dermatologic base is saturated with said cuprous chloride and with said member of the group consisting of benzyl alcohol and 2,3 dihydroxybenzoic acid.
