Abstract
A method of solubilizing a first compound in a second medium where the first compound has a limited solubility in the second medium. In particular, the method comprises reacting the first compound with the second medium. By this reaction, a product is formed whereby an active component of the first compound is covalently incorporated into the second medium. The first compound and second medium each contain at least one reactive group which will react with a reactive group of the other. In addition, the first compound comprises at least one antioxidant which will be covalently bonded to and thus effectively solubilized in the second medium by the reaction. The second medium comprises glyceride derivatives, silicones, fluorocarbons and alkoxylates containing reactive groups such as hydroxy, amino, carboxyl, ester, or amides.
