Octylphenol Ethoxylates

What is Octylphenol Ethoxylate?

Octylphenol ethoxylate is a nonionic surfactant produced by reacting octylphenol with ethylene oxide; it has emulsifying and wetting properties and is used in industrial formulations.

What is the CAS number of Octylphenol Ethoxylate?

The CAS number of Octylphenol Ethoxylate is 27193-28-8.

What is Octylphenol Ethoxylate used for?

Octylphenol ethoxylates are used in industrial cleaners; in emulsion polymerization; in agrochemicals; in textiles; and in other industrial emulsification and wetting applications. Venus Ethoxyethers manufactures and supplies in India; request a quote for your requirements.

Octylphenol ethoxylates (OPEs, CAS 27193-28-8) are nonionic surfactants from ethoxylation of octylphenol. EO chain length controls HLB, solubility, cloud point, and viscosity—yielding grades from water-dispersible liquids to water-soluble solids.

Properties by ethoxylation level

Low-mole grades (up to 6 EO) are water-dispersible; 7+ EO grades are water soluble. Higher ethoxylation increases HLB and suitability for oil-in-water emulsions in cleaning, agriculture, and industrial formulations.

Applications

OPEs serve as emulsifiers and wetting agents in institutional cleaners, agrochemical adjuvants, textile/leather processing, and as intermediates for ether sulfates, ether carboxylates, and phosphate ester dispersants.

Regulatory context and alternatives

Many markets restrict alkylphenol ethoxylates; Venus offers APEO-free alternatives including fatty alcohol ethoxylates and APE comparison guide. Contact Venus for compliant reformulation support and OPE grades where still permitted.
