Product Overview

FMEE is a non-ionic surfactant made by ethoxylating fatty acid methyl ester directly over a special catalyst, rather than going through a fatty alcohol. Against alcohol ethers it dissolves in water far faster, foams less and breaks foam quicker, and solubilises grease more strongly. Skin irritation is comparable to APG or amino acid surfactants, biodegradation is good, and it costs less than the alcohol ether it replaces.

Key Benefits

Dissolves in water very quickly, so it is easy to blend into liquid products
Low foaming with fast defoaming, which is what industrial cleaning needs
Strong grease solubilising power for hard surface cleaning
Mild: irritation comparable to APG or amino acid surfactants
Good biodegradation and a mild odour, at a lower price than alcohol ethers

Specification

Typical Data And Dosage

Typical values are indicative of the product and are not release specifications. Figures are reproduced from the manufacturer data sheet.

Component	RCO(EO)nOCH3
Appearance	Colourless or pale yellow liquid
PEG	95 +/- 5%
Water content	0.5% maximum
Saponification value	1.5 maximum
Packing	200 kg drum
Transport	Non-dangerous goods

Use Guide

Add directly to the water phase; it dissolves quickly with normal agitation.
Avoid long exposure during storage so quality is not affected.
Store and transport as non-dangerous goods in the 200 kg drum it ships in.
Where a formulation currently uses an alcohol ether, start by matching on active content and then adjust for the lower foam.

Quality Control On Your Side

Measure foam height and collapse time against the incumbent surfactant
Check grease removal on the actual soil, not on a standard test soil
Confirm skin compatibility data before using in personal care

Comparison

How It Compares With The Alternatives

Technical comparison against other ways of solving the same problem. Nothing here is a performance claim against a named commercial product.

Alcohol ether AEO	Faster water solubility, lower foam, faster defoaming and stronger grease solubilising, at a lower price.
APG	Comparable mildness at a lower cost.
NP series	A fatty acid methyl ester backbone with no alkyl phenol chemistry.

Questions

Fatty Acid Methyl Ester Ethoxylates FMEE Questions

How is FMEE different from an alcohol ether?

It is made by ethoxylating fatty acid methyl ester directly rather than a fatty alcohol. In use it dissolves faster, foams less, defoams faster and solubilises grease more strongly.

Is it mild enough for personal washing products?

The source data states irritation is comparable to APG or amino acid surfactants and lists personal washing supplies among the applications.

What packing is standard?

200 kg drums, shipped as non-dangerous goods.

What are the published specification figures?

PEG 95 +/- 5%, water content at or below 0.5%, and saponification value at or below 1.5.
