Request SDS →Oleyl Betaine (CAS 871-37-4) is an amphoteric surfactant, the inner salt of a carboxymethyl dimethyl oleyl ammonium compound. It functions as a surfactant, foam booster, and antistatic and conditioning agent, and is documented for cleansing applications in personal-care formulations.
Frequently Asked Questions
What is (carboxymethyl) dimethyloleylammonium hydroxide used for?
Also known as oleyl betaine (CAS 871-37-4), it is an amphoteric surfactant used as a primary or co-surfactant in cleansing formulations. It functions as a foam booster, antistatic agent, and hair- and skin-conditioning agent in personal-care products.
What is oleyl betaine also known as?
This material is the inner salt of a carboxymethyl dimethyl oleyl ammonium compound, commonly called oleyl betaine. It carries CAS 871-37-4 and molecular formula C22H43NO2 in the family of amphoteric (betaine) surfactants.
Is oleyl betaine a quaternary ammonium compound?
It is an amphoteric surfactant built on a quaternary ammonium center carrying a carboxymethyl (carboxylate) group, making it an inner salt (betaine) rather than a simple quat. This zwitterionic structure is why it is classed with amphoteric surfactants used as foam boosters and co-surfactants.
What is its role in cleansing formulations?
As an amphoteric surfactant it lowers surface tension, builds and stabilizes foam, and acts as a secondary surfactant that improves mildness and conditioning when blended with anionic primaries. It also provides antistatic and conditioning effects in hair-care blends.
How is oleyl betaine supplied in bulk and what documentation is provided?
It is supplied as a liquid surfactant concentrate in industrial packaging such as drums, totes, and IBCs. A Certificate of Analysis and Safety Data Sheet (SDS) are provided per lot. Contact us with your active-content and volume requirements for a bulk quote.
