Abstract
Topical deodorant and compositions are provided. The deodorant compositions include in the range of about 20 to about 80 percent by weight of an acetylsalicylic acid solution and in the range of about 20 to about 80 percent by weight of a waxy carrier. The acetylsalicylic acid solution has acetylsalicylic acid in the range of between about 5 percent by weight per unit volume of a solvent mixture up to saturation of the solvent mixture. This solvent mixture consists essentially of propylene glycol in the range of about 5 to 15 percent by volume, glycerin in the range of about 1 to 10 percent by volume, and the balance of the solvent mixture made up with one or more solvents selected from the group consisting of isopropyl alcohol, water, and ethanol, the balance of the solvent mixture comprising at least 50 percent by volume isopropyl alcohol. The waxy carrier preferably includes cetyl alcohol and sodium stearate. Thus, the composition has a waxy consistency for each of application to the skin for antiperspirant purposes.
