Description
Aluminum chloride hexahydrate (CAS 7784-13-6, formula AlCl3.6H2O) is the hydrated form of aluminum chloride, commercially referenced as Aluminum Chloride 6-Hydrate or ALUMINIUM CHLORIDE 6H2O. It carries no E-code designation and is classified under HS code 28273200 within the salts and minerals category.
In water treatment, it acts as a coagulant by releasing Al3+ ions that neutralise negatively charged suspended particles, causing them to aggregate and settle. In pharmaceutical and personal care manufacturing, it functions as an antimicrobial and antiperspirant active, while in textile and paper processing it serves as a flame retardant by promoting char formation and inhibiting combustion.
The product is supplied as a white to pale yellow crystalline solid and is available in technical and pharmaceutical grades compliant with REACH registration requirements. Packaging is offered in standard bulk formats suited to industrial procurement. Buyers should confirm grade-specific compliance documentation, including Ph.Eur. alignment where applicable.
