The invention discloses novel series of silicone esters, which are useful as antioxidants on skin. The products are produced using for a variety of hydroxyl containing actives such as vitamin A (retinol), vitamin A-2, and vitamin E. Compounds of the invention are prepared by the esterification of (a) a specific silicone methyl ester and (c) a hydroxyl functional active. The esters of the present invention allow for the formulation of personal care products in which the “active” can be formulated into a variety of solvents without the loss of activity.

硅酯系列,可作为皮肤
抗氧化剂使用。这些产品是使用多种羟基含量活性物质制备的,例如
维生素A(
视黄醇)、
维生素A-2和
维生素E。该发明的化合物是通过(a)特定的
硅甲酯和(c)羟基功能活性物质的酯化制备的。本发明的酯允许制备个人护理产品,其中“活性”可以在各种溶剂中制备而不会失去活性。
