Abstract
Antiperspirant/deodorants contain 5-90 wt % of spheroid silicone rubber powders with average particle sizes of 0.1-200 .mu.m and JIS A hardness of the silicone rubber forming said powder is 35-80. They spread well, are smooth, and have a dry feel when used.
Claims5
A composition for application to the underarm comprising 5-90% by weight based on the weight of the composition of a silicone rubber powder which is free of silicone oil, the silicone rubber powder having an average particle size of 0.1-200 microns and a JIS A hardness of 35-80;
- the remainder of the composition comprising an oil, a cyclic diorganosiloxane, an astringent selected from the group consisting of aluminum chlorohydroxide, aluminum hydroxybromide, aluminum chloride, aluminum/zirconium/glycine complexes, mixtures of aluminum chloride with aluminum hydroxychloride, and mixtures of aluminum chloride with aluminum chlorohydroxide, and an antimicrobial agent selected from the group consisting of quaternary ammonium salts, alkyldiaminoethyl glycine chloride solutions, isopropylmethylphenol, and trichlorohydroxydiphenyl ether.
