Abstract
Abstract Polar solvent-free antiperspirant compositions comprising particulate cellulose ether polymers, preferably hydroxyethyl-cellulose. These antiperspirant compositions produce less stinging and burning than compositions not containing particulate cellulose ether polymers when applied to underarm skin following shaving.
