Aluminum Chlorohydrate

Aluminum Chlorohydrate (ACH), with the chemical formula Al2(OH)5Cl·2H2O, is an inorganic polymer known for its excellent coagulation properties. It appears as a white solid powder and is soluble in water, forming a clear or slightly yellowish liquid solution with a specific gravity of 1.33-1.35g/ml at 20°C. ACH is highly effective in applications such as water treatment, where it aids in the purification process by removing impurities like iron, fluorides, and radioactive pollutants. It is also used in industrial wastewater management, particularly in the treatment of dyeing effluents. Additionally, ACH finds use in personal care products, serving as an antiperspirant and deodorant agent due to its astringent properties. It is important to note that ACH solutions are corrosive and should be handled with care.
