Abstract
A method of inhibiting the dissolution in anhydrous ethanol or isopropanol of a powdered aluminium-containing basic halide antiperspirant agent which comprises incorporating in the ethanol or isopropanol an amount effective to inhibit said dissolution of an alcohol soluble or alcohol-insoluble dissolution-inhibiting compound selected from the group consisting of compounds having a basic nitrogen function and compounds having a basic oxygen function. Examples of dissolution-inhibiting compounds are urea, thiorea, amino acids, C.sub.1 -C.sub.20 alkylamines and hydroxyalklyamines, inorganic bases, and alkali metal and alkaline-earth metal salts of inorganic acids and C.sub.1 -C.sub.20 organic carboxylic acids. The dissolution-inhibiting compound may alternatively be a particulate alcohol-insoluble inorganic drying agent such as a molecular sieve.
