Abstract

Abstract Aerosol antiperspirant compositions are provided that are highly concentrated with respect to the active astringent salt, and capable of being dispensed from aerosol containers of the foam type at a low delivery rate, comprising, in combination, an astringent salt in an amount within the range from about 8 to about 30%; a liquefied propellant, or a mixture of liquefied propellants, each with a vapor pressure at 21 DEG C. of at least 2.4 atmospheres absolute, having a low molecular weight, in an amount of at least 0.15 mole per atmosphere absolute pressure in the container at 21 DEG C. per 100 g of composition; a nonvolatile miscible organic liquid in an amount within the range from about 0.1 to 30% by weight of the composition; a bulking agent in an amount within the range from about 0.1 to about 5% by weight of the composition; and a solid aliphatic carboxylic acid having from about fourteen to about twenty-two carbon atoms in a straight chain and in an amount within the range from about 0.1 to about 5% by weight of the composition to enhance adherence of the antiperspirant salt to the skin.
