Brief Overview

Aluminum chlorohydrate is a simple form of a group of FDA-recognized aluminum-based salts that can be used to reduce underarm wetness in underarm antiperspirant products. 


Manufacturing Process

Because of the explosion hazard related to hydrogen produced by the reaction of aluminum metal with hydrochloric acid, the most common industrial practice is to prepare a solution of aluminum chlorohydrate (ACH) by reacting aluminum hydroxide with hydrochloric acid. The ACH product is reacted with aluminum ingots at 100 °C using steam in an open mixing tank. The Al to ACH ratio and the time of reaction allowed determines the polymer form of the PAC n to m ratio.
