Abstract:

The present invention is directed to a clear antiperspirant or deodorant gel composition which exhibits reduced staining while retaining excellent aethetic attributes and efficacy. The gel composition is a water-in-oil emulsion having a viscosity of about 50,000 to 250,000 cP, preferably about 100,000 to 200,000 cP. The water phase comprises about 75 to 90% of the composition and contains a deodorant or antiperspirant effective amount (e. g. about 3 to 25%) of an antiperspirant active dissolved therein. The oil phase comprises about 10 to 25% of the composition and contains a silicone oil and a polyether substituted silicone emulsifying agent. The silicone oil comprises a mixture of a non-volatile silicone, preferably a non-volatile linear silicone, and a volatile linear silicone. It has been found that reducing the amount of non-volatile silicone in the known gel composition to a relatively low level (e. g. below about 5%) and adding an amount of volatile linear silicone to the composition (e. g.
