Abstract
Oil-soluble vitamins such as vitamin A and vitamin E can be entrapped in the oil phase of an elastomeric silicone polyether. The vitamin entrapped oil phase can then be emulsified and stabilized without requiring the use of other surfactants. The vitamin entrapped oil phase and water-in-oil emulsions prepared from the vitamin entrapped oil phase are useful in water-based skin and cosmetic compositions.
