Frequently Asked Questions
What is hydrogenated tallowalkyl (2-ethylhexyl) dimethyl ammonium methylsulfate?
It is a cationic quaternary ammonium compound (CAS 308074-31-9) — a dialkyl dimethyl ammonium methylsulfate supplied at approximately 82% actives in water. Quaternary ammonium salts of this type are used as fabric-softening, antistatic, and conditioning agents.
What is this quaternary ammonium compound used for?
It serves as a cationic softener active for rinse-added fabric-softening formulas, as a charge-neutralizing antistatic agent, and as a substantive cationic film former for surface conditioning. The methylsulfate counterion makes it an alternative to chloride-based dialkyl quats.
What does the 82% actives in water specification mean?
It means the supplied material is approximately 82% active quaternary ammonium compound with the balance being water. This is the as-shipped concentration — adjust your formulation dosing to the actual active content stated on the CoA.
What is the HS code for this quaternary ammonium methylsulfate?
It classifies under HS 2923.90 (quaternary ammonium salts and hydroxides, other). Confirm destination-country tariff treatment with your customs broker; RawSource supplies documentation per shipment.
What bulk packaging and MOQ are available?
This cationic active is supplied at ~82% actives in drums and totes for manufacturing use. MOQ, lead time, and pricing are quote-based — request a bulk quote with your target volume; an SDS and CoA confirming actives content accompany the order.
What is the REACH and TSCA regulatory status of Hydrogenated Tallow Alkyl (2-Ethylhexyl) Dimethyl Ammonium Methylsulfate?
Hydrogenated Tallow Alkyl (2-Ethylhexyl) Dimethyl Ammonium Methylsulfate (CAS 308074-31-9) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
