ABSTRACT:
A novel stable anhydrous paste or cream composition having superior ultradry characteristics when applied to the skin comprising an antiperspirant or deodorant agent and an oil absorbent material homogeneously dispersed in a vehicle comprising about 25-55% of a volatile silicone and a clay suspending/thickening agent in the form of a gel, preferably a bentonite gel. Additionally preferable ingredients are stability agents to prevent syneresis (oil separation) such as the fatty acid metal salts, more specifically zinc, aluminum, calcium, magnesium, and lithium stearates. Additional thickeners, binders, suspending agents, emollients and nonionic emulsifiers may be added as desired to further enhance the aesthetics of the cream product. The resultant dry-feel cream products spread easily, are not wet, oily or sticky, and vanish almost immediately on rub-in when applied to the skin.
