Aluminum Dichlorohydrate

What Is It?

Aluminum Chlorohydrate and Aluminum Sesquichlorohydrate are solids. Aluminum Dichlorohydrate occurs as a white to yellow powder. The Aluminum Chlorohydrate complexes are used in the formulation of personal cleanliness products.

Why Is It Used?

Aluminum Chlorohydrate complexes are ingredients that are applied to the skin to reduce the production of perspiration at the site of application, to induce a tightening or tingling sensation of the skin and to reduce or eliminate unpleasant odor and that protect against the formation of such odors on the skin.

Scientific Facts

The Aluminum Chlorohydrate complexes are inorganic compounds. Aluminum is commonly found in the Earth’s crust.

Safety Information

The Food and Drug Administration (FDA) has reviewed the safety of Aluminum Chlorohydrate complexes and has approved the use of these ingredients in Over-The-Counter (OTC) antiperspirant drug products. The Cosmetic Ingredient Review (CIR) has deferred evaluation of these ingredients because the safety has been assessed by FDA. This deferral of review is according to the provisions of the CIR Procedures.

The Aluminum Chlorohydrate complex commonly used in deodorants and antiperspirants is Al2Cl(OH)5. Aluminum is widely used in food contact articles including cans, foils and cooking utensils.

More Scientific Information

The Aluminum Chlorohydrates are complex inorganic salts that consist of aluminum and hydrogen chloride. These compounds are polymeric, bound loosely to water and include a range of aluminum to chloride ratios from 2.1-1.9 to 1 for the Chlorohydrate, from 1.25-0.9 to 1 for the Dichlorohydrate, and from 1.9-1.25 to 1 for the Sesquichlorohydrate. Aluminum Chlorohydrate is also used as a flocculant in water purification.
