Methyl ester ethoxylates

What is Methyl ester ethoxylates?

Fatty acid methyl esters (FAME)—from coconut, palm kernel, soybean, and other vegetable sources—can be ethoxylated directly using Venus patented catalyst technology to produce methyl ester ethoxylates (CAS Number: 67784-80-9). Compared with conventional fatty alcohol ethoxylates, methyl ester ethoxylates offer lower…

What is Methyl ester ethoxylates used for?

Methyl ester ethoxylates attach ethylene oxide to the ester carbonyl rather than a terminal alcohol hydroxyl. Wetting strength is comparable to fatty alcohol ethoxylates of equivalent alkyl chain length, but MEE grades do not form viscous gels at high active levels—a key benefit for compact liquid detergents. CMC and… Venus Ethoxyethers manufactures and supplies in India; request a quote for your requirements.

Fatty acid methyl esters (FAME)—from coconut, palm kernel, soybean, and other vegetable sources—can be ethoxylated directly using Venus patented catalyst technology to produce methyl ester ethoxylates (CAS Number: 67784-80-9). Compared with conventional fatty alcohol ethoxylates, methyl ester ethoxylates offer lower foam, favourable ecotoxicity, and excellent biodegradability while maintaining strong wetting and detergency.

Structure and performance advantages

Methyl ester ethoxylates attach ethylene oxide to the ester carbonyl rather than a terminal alcohol hydroxyl. Wetting strength is comparable to fatty alcohol ethoxylates of equivalent alkyl chain length, but MEE grades do not form viscous gels at high active levels—a key benefit for compact liquid detergents. CMC and cloud point can be tuned via alkyl chain length and degree of ethoxylation. Narrow homologue distribution supports consistent batch performance and predictable viscosity build with electrolytes.

Applications

MEE products function as primary or co-surfactants in laundry liquids, hard-surface cleaners, laundry pre-spotters, and institutional detergents. They emulsify oily soils, build viscosity in low-active formulations, and pair well with anionic and amphoteric systems. Personal care formulators use selected grades in mild cleansing products where low irritation and sustainable feedstock stories matter.

Environmental and regulatory profile

Derived from renewable methyl ester feedstocks, methyl ester ethoxylates align with eco-label and RSPO sourcing requirements increasingly demanded in EU and export markets. Venus provides documentation for biodegradability testing references and impurity profiles to support customer registrations.

Manufacturing and custom grades

Venus Ethoxyethers manufactures methyl ester ethoxylates at integrated Indian facilities with toll and custom ethoxylation services. Explore the methyl ester ethoxylate guide for market and formulation detail, or contact us for samples, SDS, and chain-length recommendations for your application.

Patented catalyst technology

Direct ethoxylation of fatty acid methyl esters using Venus patented catalyst systems enables efficient production without converting to alcohol first—supporting cost-competitive, sustainable surfactant supply for global detergent and cleaning markets.
