QUATERNIUM-18- ▸ Fabric softening: Cationic active for rinse-cycle softeners and conditioning formulations.
- ▸ Hair and skin conditioning: Substantive quaternary that deposits on keratin and reduces static.
- ▸ Cationic emulsifier: Stabilizes oil-in-water systems that need a positively charged emulsifier.
- ▸ Antistatic agent: Controls static charge on fibers and surfaces.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →A twin-tail cationic (quaternary ammonium) surfactant supplied as CAS 61789-80-8, built on two hydrogenated tallow alkyl chains. The double hydrophobic tail and permanent positive charge make it substantive to negatively charged fibers and surfaces, the basis for its use as a fabric-softening and conditioning active, an antistatic agent, and a cationic emulsifier.
Frequently Asked Questions
What is quat emulsifier used for?
This twin-tail cationic (quaternary ammonium) surfactant, CAS 61789-80-8, is used as a fabric-softening and conditioning active, a cationic emulsifier for oil-in-water systems, and an antistatic agent. Its double hydrophobic tail and permanent positive charge make it substantive to negatively charged fibers and surfaces.
Is BTMS a quat?
BTMS (behentrimonium methosulfate) is a separate quaternary ammonium ingredient and is not this product. This quat emulsifier is a distinct twin-tail cationic surfactant built on two hydrogenated tallow alkyl chains under CAS 61789-80-8; confirm identity against the CAS number when comparing.
Why is this material called a cationic emulsifier?
It carries a permanent positive (quaternary nitrogen) charge, so it stabilizes oil-in-water systems that need a positively charged emulsifier and deposits readily onto anionic substrates like keratin and textile fibers. That same charge underlies its softening and antistatic performance.
What CAS number and HS code apply to quat emulsifier?
It is supplied under CAS 61789-80-8 and classified under HS heading 3402.41 (cationic organic surface-active agents). Verify final import classification with your customs broker for the destination market.
What packaging and MOQ are available for bulk quat emulsifier?
RawSource distributes this surfactant in industrial bulk formats to manufacturers. Pricing varies with volume and market conditions, so submit a bulk RFQ with your target quantity to receive pack sizes, MOQ, lead time, and a CoA/SDS.
