Aluminum Chloride: Antiperspirant Active Ingredient for Sweating

Aluminum is a very widespread chemical element and the most abundant metal in the Earth's crust.

The aluminum salt aluminum chlorohydrate (ACH) is a water-soluble compound derived from aluminum and used as an active ingredient in everdry antiperspirants.

This salt is the primary and sole active ingredient in antiperspirants and deodorants that can effectively reduce sweat and, consequently, sweat odor.

Aluminum chloride narrows the sweat pores, thus regulating sweat production in the long term. This results in an astringent (narrowing) effect. Aluminum chloride in antiperspirant products has a cumulative effect, which reduces the frequency of application over time. Visible sweating diminishes, requiring only occasional use.
