Clear, greaseless skin-care compositions

摘要

The present invention relates to compositions including anhydrous compositions which include a dimethicone crosspolymer and/or dimethicone elastomer gum and one or more skin care products which may include retinoic acid, retinoic acid derivatives, retinal, retinol and/or retinyl esters, and methods of making, storing, and using such compositions.

主权项

1. A method for making an anhydrous topical composition comprising the steps:
combining a low molecular weight silicone component consisting essentially of one or more linear silicone component having a measurable vapor pressure at 25° C., and a therapeutically effective amount of an active component selected from the group consisting of retinoic acid, retinoic acid derivatives, retinal, retinol, retinyl esters, and mixtures thereof at ambient temperature to make an admixture, blending high molecular weight silicone polymer having an average molecular weight of between 100,000 and about 5,000,000 Daltons with said admixture, wherein said combining and blending steps are conducted at ambient temperature without the use of an inert gas.
