Aluminum chloride hexahydrate

Aluminum chloride hexahydrate (CAS 7784-13-6) is the hydrated crystalline salt form of aluminum chloride, commonly sourced under the trade name Hydrosal Gel in personal care and pharmaceutical supply chains. It functions primarily as a coagulant, flocculant, and catalyst precursor across water treatment, textile processing, and industrial manufacturing sectors. In municipal and industrial water treatment, it acts as a coagulant.

This material destabilizes suspended solids and colloidal matter, enabling efficient clarification and sludge removal. Textile and leather processors use it as a mordant and fixative to improve dye uptake and bonding. In pulp and paper manufacturing, it supports rosin sizing and retention aid systems that control fiber bonding and sheet formation. Pharmaceutical and cosmetic formulators incorporate it as an active antiperspirant agent.

It also serves as a precursor in the preparation of aluminum-based compounds. Aluminum chloride hexahydrate is supplied as white to off-white crystalline granules or powder for various industrial uses. Standard commercial grades include technical grade for industrial water treatment and textile applications, as well as pharmaceutical/USP-grade material for personal care and healthcare formulations.

Bulk supply is typically available in 25 kg bags or bulk sacks, with solution forms offered for select water treatment applications. This ensures reliable delivery for large-scale manufacturing and processing needs.
