What is it?

Aluminum Chlorohydrex Propylene Glycol is a complex of aluminum chlorohydrate and propylene glycol in which some of the waters of hydration of the aluminum chlorohydrate have been replaced by propylene glycol. It contains the equivalent of not less than 90 percent and not more than 110 percent of the labeled amount of anhydrous aluminum chlorohydrate.

Aluminum Chlorohydrex complexes are ingredients commonly used in antiperspirants to decrease the production of sweat at the site of application and reduce unpleasant odor.

The U.S. Food and Drug Administration (FDA) has reviewed the safety of aluminum chlorohydrex complexes and has approved these ingredients for use in over-the-counter (OTC) antiperspirant drug products.[1][2]
