Abstract
By combining dihydroxyacetone as the active skin coloring agent in combination found with a blend of dispersion polymers and polyester polymers, an easily employed, self-tanning formulation is realized which produces a long lasting, naturally appearing coloring of the skin without any orange pigmentation being produced. In addition, tan colored skin produced by the present invention maintains the desired color for extended periods of time. In the present invention, the dispersion polymers stabilize the dihydroxyacetone as well as provide a thickening agent for the composition. In addition, the present invention also incorporates an oil soluble polyester polymer in combination with the other ingredients which achieves a formulation which provides a slow release of the active ingredient.
