Aluminum Chlorohydrate (ACH), also known as polyaluminum chloride hydroxide or basic aluminum chloride, is an inorganic polymeric compound with the molecular formula Al2(OH)5Cl·2H2O, a molecular weight of 210.48 g/mol, and CAS No. 12042-91-0. It is a hydrolysis product intermediate between aluminum chloride and aluminum hydroxide, polymerized through hydroxyl bridging, and carries a varying number of hydroxyl groups in its molecule. As an important inorganic polymeric compound, aluminum chlorohydrate is widely used in many industrial fields. Its unique chemical structure and physical properties make it an indispensable raw material in water treatment, personal care products, and pharmaceuticals.
The physicochemical properties of aluminum chlorohydrate appear as a white or slightly yellow solid powder, readily soluble in water, and its solution is a colorless transparent liquid. The specific gravity of the 50% liquid is 1.33-1.35 g/ml at 20°C, and the aqueous solution is corrosive. Its density is 1.95 (at 20°C), and the vapor pressure is 0.001 Pa at 20°C. In cosmetic ingredients, it is mainly used as an antiperspirant and astringent. A distinguishing feature of aluminum chlorohydrate is that it has the highest aluminum content of any solution-based aluminum product on the market — 23% Al2O3 (w/w); ACH with 83%-90% basicity also has the highest basicity of any solution-based aluminum salt. Basicity (degree of alkalization) refers to the degree of acid neutralization and also represents how highly polymerized the polyaluminum in ACH is. The highly polymerized aluminum in ACH carries a higher cationic charge than standard salts such as alum or polyaluminum chloride, and even other aluminum salt products. As a multifunctional inorganic polymeric compound, aluminum chlorohydrate has a wide range of applications, mainly covering three major fields: water treatment, personal care products, and pharmaceuticals. In different application fields, aluminum chlorohydrate performs different functions, mainly due to its unique chemical structure and physical properties. The following is a detailed analysis of the specific performance and mechanism of action of aluminum chlorohydrate in each major application field.
