ANTIPERSPIRANT COMPOSITION ABSTRACT An antiperspirant composition comprising AlCl3 and one or more alumi- nium salts of one or more acids dissolved and/or dispersed in a suitable carrier, the acid or acids having no pK value in aqueous solution below 2.5, preferably not below 3, in particular not below 3.5, especially not below 4. The acid may preferably itself have an- tiperspirant, deodorant, astringent, antiseptic, antimicrobial, an- tifungal, or antiinflammatoric properties and may in particular be selected from acetylsalicylic acid, salicylic acid, benzoic acid, propionic acid, octanoic acid, undecanoic acid, sorbic acid, ascorbic acid, lactic acid, malic acid, stearic acid, citric acid, phthalic acid, tartaric acid, or a naturally occurring amino acid. The antiperspirant composition causes significantly less or no ir- ritation of the skin because the acid or acids, upon release from its aluminium salt, reacts with and removes the hydrochloric acid formed as a result of the reaction between AlCl3 and the water in sweat.
