Aluminum Chlorohydrate

Aluminum chlorohydrate (ACH) is a group of specific aluminum salts primarily used as antiperspirants and coagulating agents in water purification.

• Composition: Aluminum chlorohydrate is typically formulated as a solution or powder and consists of various polymeric species containing aluminum ions (Al^3+) and chloride ions (Cl^-), along with water molecules.
• Function: In antiperspirants, aluminum chlorohydrate works by forming a gel-like plug in the sweat duct, reducing the flow of sweat to the skin’s surface. This helps to control perspiration and reduce body odor. In water purification, aluminum chlorohydrate acts as a coagulant, facilitating the removal of suspended particles and impurities by causing them to clump together and settle out of the water.
• Application: In personal care products, aluminum chlorohydrate is a common active ingredient in antiperspirants, deodorants, and other cosmetic formulations designed to reduce sweating and body odor. In water treatment, it is used in the purification of drinking water, wastewater treatment, and the treatment of industrial process water to clarify and disinfect water supplies.
• Characteristics: Aluminum chlorohydrate solutions are typically colorless or slightly yellow and have a slightly acidic pH. They are soluble in water and can form a viscous solution or suspension depending on the concentration and formulation.
• Usage: In antiperspirants, aluminum chlorohydrate is applied topically to the skin in the form of roll-ons, sprays, sticks, or creams. In water treatment, it is typically added to the water supply as a liquid solution or as a solid powder and mixed thoroughly to ensure even distribution.
