Full Description

Octylphenol Ethoxylate (CAS 9036-19-5), also called octoxynol, is a nonionic surfactant formed by ethoxylating tert-octylphenol. It is used as a wetting agent, detergent, and emulsifier across industrial cleaning, emulsion, and process applications.

Frequently Asked Questions

What is 2-(2-[4-(1,1,3,3-tetramethylbutyl)phenoxy]ethoxy)ethanol used for?

This material (CAS 9036-19-5), also called octylphenol ethoxylate or octoxynol, is a nonionic surfactant formed by ethoxylating tert-octylphenol. It is used as a wetting agent, detergent, and emulsifier across industrial cleaning, emulsion, and process applications.

What is octylphenol ethoxylate?

It is a nonionic surfactant made by adding ethylene oxide units to tert-octylphenol. The resulting amphiphile lowers surface tension and stabilizes oil-in-water emulsions, which is why it is used in industrial cleaning and process formulations.

What is the CAS number and molecular formula?

The CAS number is 9036-19-5 and the representative molecular formula is C18H30O3. It is classified within the nonionic surfactant family.

Is octylphenol ethoxylate the same as nonylphenol ethoxylate?

No. Octylphenol ethoxylate is built on a tert-octylphenol base, whereas nonylphenol ethoxylate is built on a nonylphenol base; they are distinct surfactants with different CAS numbers. Specify CAS 9036-19-5 to ensure the octylphenol grade.

What is the bulk price and what HS code applies?

It is classified under HS 3402.42 (non-ionic surface-active agents) and supplied with a CoA and SDS. Submit a bulk RFQ with your target volume and packaging for current pricing.
