Abstract
Improved antiperspirant compositions having an astringent material suspended in a hydrophobic medium, and emulsions of aqueous solutions of astringent materials in a hydrophobic medium, said compositions having added thereto from 1 to 5% by weight of a C.sub.3 to C.sub.8 alkanediol compound.
Claims10
An improved method for increasing the antiperspirant efficacy of a water-in-oil emulsion antiperspirant or suspension stick, selected from the group consisting of suspensions of an astringent compound in a hydrophobic medium and emulsions of an aqueous solution of an astringent compound in a hydrophobic medium, wherein the improvement comprises incorporating into said composition from about 1 to 5 percent by weight, based on the total weight of said composition, of a saturated C.sub.3 to C.sub.8 alkanediol compound;
- said diol compound having no more than one carbon atom separating the hydroxy groups thereof.
An improved water-in-oil antiperspirant emulsion stick composition comprising a hydrophobic medium, a metallic astringent compound, and wherein the improvement comprises from about 1 to 5 percent by weight, based on the total weight of said composition, of a saturated C.sub.3 to C.sub.8 alkanediol compound;
- said diol compound having no more than one carbon atom separating the hydroxy groups thereof.
