Surfactants - Cationic Available — Bulk Only

Di(C14-18 alkyl) Dimethyl Ammonium Chloride (Dialkyldimethylammonium Chloride)

CAS 68002-59-5

Saturated twin-chain cationic surfactant for softening, conditioning, and emulsification. Like other dialkyldimethylammonium chlorides it is substantive to negatively charged fibers and surfaces, and is used as a fabric-softening and conditioning active, an antistatic agent, and a cationic emulsifier.

Full Description

A twin-chain cationic surfactant (CAS 68002-59-5) carrying two saturated C14-C18 alkyl groups on a quaternary nitrogen. Like other dialkyldimethylammonium chlorides it is substantive to negatively charged fibers and surfaces, and is used as a fabric-softening and conditioning active, an antistatic agent, and a cationic emulsifier.

Frequently Asked Questions

What are quaternary ammonium compounds, di-C14-18-alkyldimethyl, chlorides used for?

This twin-chain cationic surfactant (CAS 68002-59-5) is used as a fabric-softening and conditioning active for rinse-cycle and industrial softeners, a substantive conditioning agent for hair and textiles, a cationic emulsifier for oil-in-water systems, and an antistatic agent for treated substrates.

What is this compound made of?

It is a dialkyldimethylammonium chloride carrying two saturated C14-C18 alkyl groups on a quaternary nitrogen, supplied under CAS 68002-59-5. The twin-chain structure and permanent positive charge make it substantive to negatively charged fibers and surfaces.

Why is it described as substantive to fibers?

Its quaternary nitrogen gives a permanent positive charge that is attracted to anionic surfaces such as textile fibers and keratin, so it deposits and stays bound. That deposition is what delivers its softening, conditioning, and antistatic function.

What CAS number and HS code apply to this material?

It is supplied under CAS 68002-59-5 and classified under HS heading 3402.41 (cationic organic surface-active agents). Confirm the final import classification with your customs broker for the destination country.

How is bulk di-C14-18-alkyldimethyl ammonium chloride supplied and priced?

RawSource distributes it to manufacturers in industrial bulk formats. Pricing depends on volume and market conditions, so we quote per order; request a bulk RFQ for pack sizes, MOQ, lead time, and a CoA/SDS.
