Abstract
New cosmetic formulations containing free and derivatized forms of conjugated linoleic acid. These ingredients have beneficial effects related to their medicinal and nutritional properties, but also are engineered for their compatibility with standard cosmetic ingredients. Certain vitamin/conjugated linoleic acid combinational molecules are described which deliver equimolar amounts of both free components to viable layers of the epidermis, thereby obtaining multiple functionality of the final product.
