Abstract
Sunscreens are colored with oil-soluble dyes approved for use in skin care products (such as sunscreens, lotions, etc.). The color imparted by the dyes substantially disappears shortly after the sunscreen emulsion is applied to skin. This colored sunscreen emulsion includes a oil-soluble phase, at least one sunscreen active agent, water, and an emulsifier. The oil-soluble phase comprises from about 0.0005 to about 0.5 percent by weight of the complete emulsion of at least one oil-soluble dye. The dye imparts a color other than white to the sunscreen emulsion. The sunscreen active ingredient is provided in an amount effective to protect against the actinic radiation of the sun. Sufficient water is provided to form the colored emulsion. The emulsion additionally contains at least one emulsifier in an amount effective to provide an at least substantially stable emulsion. Other optional ingredients may also be compounded into the sunscreen formulations.
