Aluminum chlorohydrate is a group of water-soluble aluminum complexes with the general formula AlnCl(3n-m)(OH)m. It is included up to 25% in over-the-counter hygiene products as an active antiperspirant agent. The primary site of action of aluminum chlorohydrate is at the level of the stratum corneum layer, which is relatively near the skin surface. It is also used as a coagulant in the water purification process.

4 Drug and Medication Information

4.1 Drug Indication

Indicated for use as an antiperspirant.

5 Pharmacology and Biochemistry

5.1 Pharmacology

Aluminum chlorohydrate serves to reduce excessive sweating by directly blocking the sweat ducts.

5.2 Absorption, Distribution and Excretion

Absorption

Penetration of aluminum chlorohydrate following dermal application is minimal, with the rate being around 0.01% and up to 0.06% in pre-damaged skin. In a preliminary study, dermally applied aluminium chlorohydrate displayed 0.012% of the applied aluminium being absorbed through the skin, which accounts for 4 mcg of aluminum following a single dermal application. This is about 2.5% of the aluminium typically absorbed by the gut from food over the same time period.
