Octylphenol Ethoxylates

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.

Ethoxylates are surfactants made by reacting alcohols, phenols, or fatty acids with ethylene oxide. They are non-ionic surfactants used in detergents, personal care, industrial cleaners, and other applications.

Venus Ethoxyethers Pvt. Ltd. manufactures ethoxylates in India, including fatty alcohol ethoxylates, alkyl phenol ethoxylates, castor oil ethoxylates, and amine ethoxylates. We supply from our Goa facility.

Narrow-range ethoxylates have a more precise molecular weight distribution for consistent performance. Broad-range ethoxylates have a wider distribution and are typically more cost-effective. Use narrow-range when precise performance is required.

Yes, many ethoxylates are approved for personal care and cosmetics. They are used in shampoos, lotions, and similar formulations. Our products meet regulatory and quality standards for personal care.
