  • Antiperspirant compositions
    Patent number: 5888486
    Abstract: The present invention is directed to antiperspirant compositions comprising an antiperspirant compound, like an astringent salt; a cyclomethicone, a silicone polymer wax derived from beeswax and a fatty alcohol. The antiperspirant compositions are viscous compositions that are highly stable and essentially non-whitening and non-staining to skin and clothing after topical application. These desirable properties are attained by the inclusion of the specific silicone compound derived from beeswax.
