Cationic Surfactants List

Cationic Surfactants List are quaternary-ammonium surface-active agents used as antistatic agents, emulsifiers, softeners, conditioners and broad-spectrum biocides.

In this category: This category covers cetyl/dodecyl/octadecyl trimethyl ammonium chloride (CTAC, DTAC, OTAC), didecyl/dioctyl dimethyl ammonium chloride (DDAC) and amine oxides, used in personal care, textiles, organoclay and industrial water treatment. Their positive charge makes them effective surfactants and, for some, bactericides and algicides.

Cationic surfactants are compounds that have a positive charge, making them attractive for use in industrial and commercial applications such as cleaners, detergents, wetting agents and fabric softeners. Cationic surfactants are also used in products like shampoos, hair conditioners and other personal care items. They work by reducing surface tension of liquids so that dirt particles can be more easily removed from fabrics and surfaces. Cationic surfactants are effective at removing grease stains, dirt and oils, leaving behind clean surfaces without any residue.

Cationic Surfactants List — Frequently Asked Questions (FAQ)

What are cationic surfactants used for?

Cationic (quaternary-ammonium) surfactants are used as antistatic agents, emulsifiers, softeners and conditioners in personal care and textiles, as phase-transfer catalysts and organoclay modifiers, and as broad-spectrum bactericides and algicides in water treatment and disinfection.

What is the difference between CTAC, DTAC and OTAC?

They differ in alkyl-chain length: DTAC (C12), CTAC (C16) and OTAC (C18). Longer chains give stronger softening and substantivity; shorter chains give better solubility and biocidal action. The right one depends on the application — conditioning, antistatic, emulsifying or biocidal.

Does VCYCLETECH manufacture cationic surfactants?

Yes. VCYCLETECH supplies cationic quaternary-ammonium surfactants factory-direct in China, ISO 9001/14001/45001 certified, with a COA on every batch, free samples and OEM/ODM service.
