PAC Poly Aluminium Chloride Efficient and Cheap Chemical Auxiliary Agent

Product Description

Aluminium chlorohydrate is a group of water-soluble, specific aluminum salts having the general formula AlnCl(3n-m)(OH)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification. In water purification, this compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminum salts such as aluminium sulfate, aluminium chloride and various forms of polyaluminium chloride (PAC) and polyaluminium chlorisulfate, in which the aluminum structure results in a lower net charge than aluminium chlorohydrate. Further, the high degree of neutralization of the HCl results in minimal impact on treated water pH when compared to other aluminium and iron salts.

Uses
PAC is one of the most common active ingredients in commercial antiperspirants. The variation most commonly used in deodorants and antiperspirants is Al2Cl(OH)5. It is also used as a coagulant in water and wastewater treatment processes to remove dissolved organic matter and colloidal particles present in suspension.
