Request SDS →Aluminum chlorohydrate (CAS 12042-91-0) is a basic aluminum chloride (aluminum chloride hydroxide) complex. It is used as a coagulant/flocculant in water purification and as an astringent active in antiperspirant formulations, with additional use in leather, paper, and pulp processing.
Frequently Asked Questions
What is aluminum chlorohydrate (ACH) used for?
Aluminum chlorohydrate (CAS 12042-91-0) is a basic aluminum chloride complex used primarily as a coagulant/flocculant in water purification. It also serves as a processing aid in pulp, paper, and leather, and as an astringent active in personal-care formulations.
What is the difference between aluminum chlorohydrate and aluminum sesquichlorohydrate?
Both are basic aluminum chlorides differing in their aluminum-to-chloride ratio (basicity): sesquichlorohydrate carries a higher chloride content than standard chlorohydrate. The distinction affects coagulation behavior and formulation properties; specify which you require so we quote the correct material.
What is the CAS number for aluminum chlorohydrate?
The CAS number is 12042-91-0. It is an aluminum chloride hydroxide complex; confirm the exact assay and basicity needed when requesting a quote and Certificate of Analysis.
How is aluminum chlorohydrate used in water treatment?
It acts as a coagulant/flocculant, neutralizing suspended-particle charge so solids aggregate and settle in potable and process-water clarification. It is valued for low residual aluminum carryover relative to some alternative coagulants.
Where can I buy aluminum chlorohydrate in bulk?
RawSource distributes aluminum chlorohydrate in bulk to manufacturers and water-treatment operators, supplied in drums, totes, and IBCs depending on solution or solid form. Request a bulk quote with your volume, grade, and destination; we provide CoA and SDS.
