Frequently Asked Questions

What is aluminum chloride hexahydrate used for?

Aluminum chloride hexahydrate (CAS 7784-13-6, AlCl3·6H2O) is the hydrated form of aluminum chloride. Industrially it serves as a processing aid and aluminum source in textile dyeing, wood-preservation systems, and aqueous chemical processes, and as an astringent ingredient in personal-care formulations.

What is the chemical formula of aluminum chloride hexahydrate?

The formula is AlCl3·6H2O (also written AlCl3H12O6), CAS 7784-13-6. It is the six-water hydrate of aluminum chloride, distinct from the anhydrous salt.

Is aluminum chloride hexahydrate water soluble?

Yes. As a hydrated aluminum chloride salt it is readily soluble in water, forming an acidic aqueous solution, which is why it functions as an aluminum source in aqueous dyeing and processing baths.

What grades of aluminum chloride hexahydrate does RawSource supply?

We supply this material to USP/EP/BP pharmacopeia specifications. Grade availability and conforming Certificate of Analysis (CoA) are confirmed at quote; request the current spec sheet and SDS with your inquiry.

What is the HS code and bulk packaging for aluminum chloride hexahydrate?

It classifies under HS 2827.32 (chlorides of aluminum). RawSource ships bulk in drums, bags, and palletized quantities; submit volume and destination for a bulk quote, CoA, and SDS.
