Frequently Asked Questions
What is stearyltrimethylammonium chloride used for?
Steartrimonium chloride (stearyltrimethylammonium chloride, CAS 112-03-8) is a quaternary ammonium compound and cationic surfactant used as a hair-conditioning agent. It provides cationic conditioning and detangling in hair-care products and reduces static charge on hair and fibers as an antistatic agent.
Is stearyltrimethylammonium chloride a cationic surfactant?
Yes. It is a single-chain quaternary ammonium salt carrying a positive charge on the nitrogen, which lets it adsorb to negatively charged hair and fiber surfaces. That charge is what drives its conditioning and antistatic performance.
Is stearyltrimethylammonium chloride the same as cetrimonium chloride?
No. Both are conditioning-grade trimethylammonium quaternary surfactants, but steartrimonium chloride (CAS 112-03-8) has a C18 stearyl alkyl chain, while cetrimonium chloride has a C16 cetyl chain. The chain length affects substantivity and feel in formulations.
How is stearyltrimethylammonium chloride supplied in bulk?
We supply it to manufacturers in bulk industrial packaging such as drums and totes. CAS is 112-03-8; HS classification is 2923.90 (quaternary ammonium salts, other). Request a quote with your volume and packaging for current bulk pricing, CoA, and SDS.
What HS code applies to stearyltrimethylammonium chloride?
It is classified under HS 2923.90, quaternary ammonium salts and hydroxides, other. Verify the exact destination subheading with your customs broker before import.
