Abstract
A multiple emulsion of the type W.sub.1 /O/W.sub.2 is made by first preparing a primary emulsion W.sub.1 /O using a silicone fluid as the oil phase (O), and an elastomeric silicone polyether as an emulsifier, for dispersing water phase W.sub.1 into oil phase (O). The primary emulsion W.sub.1 /O is then added and dispersed into a final continuous water phase W.sub.2 to form a multiple emulsion W.sub.1 /O/W.sub.2. The multiple emulsions are useful for treating the hair, the skin, or the underarm areas of the human body. Vitamins or drugs can be included in the oil phase (O) or in either aqueous phase W.sub.1 or W.sub.2 to enhance the benefits of the multiple emulsions in personal care applications.
