CMEE Coconut Methyl Ester Ethoxylates CAS 65218-33-7

CMEE Coconut Ethoxylates are easy to work with and have a very low freezing point.

It is mild and eco-friendly. CMEE Coconut Methyl Ester Ethoxylates have low foam and are easy to wash. Coldwater dissolution speed, no gel phase, good compatibility.

Initially, the Fatty Acid methyl Ester was primarily used to make fatty alcohols. Another use of this ester is sulfonating fatty acids methyl esters a= sodium chloride, also known as MES.

The disodium generated by MES can have a negative impact on the washing performance. It is difficult, too, to manufacture high-concentration products that are viscous and difficult to price compete with linearalkylbenzeneSodiumSulfonate. Fatty acid methyl ester is made from renewable oil which is suitable for human living conditions.

With the increasing global environmental protection standards, the percentage of surfactants produced from renewable sources has increased, as well as the production of natural oil. Therefore, the use and production of fatty acid-methyl ester have been gradually increasing. Recently, both domestic and foreign researchers have explored the application of fatty acids methyl esters in order to expand its field.

Japanese Lion and German Condia have been comparing FMEE and laurate ether (alcohol ether) since the 1990s.

Both have similar surface tension properties, such as wetting power, but the former’s foaming power is less than alcohol ether. The water solubility in the former also is lower.

Henkel has found that fatty acid methyl esters ethoxylates containing a mass fraction of 60% EO have a greater ability to remove stains than alcohol ethers (AEO) with the same carbon number when heated at 40C.

A patent indicates that fatty-acid methyl ester ethoxylates can be used in a variety of applications due to the excellent surface properties.

In China, technical staff of China National Institute of Daily Chemical Industry have developed a technology and catalyst for the preparation of FMEE utilizing fatty acid methyl ester as raw material with ethylene oxide added. They also studied the synthesis of FMEE utilizing a self-made catalyst.

The results indicate that FMEE is not only similar to AEO in terms of properties, but also offers the following advantages: low foaming, quick water solubility (strong oil solubilization), less skin irritation, and good biodegradability. This makes FMEE ideal for hard surface cleaning as well as liquid cleaning pesticides emulsifiers.

China Daily Chemical Industry Research Institute and Fushun Dongyuan Chemical Plant have completed two industrial scale production experiments in 2002.

The manufacturer uses cMEE-8, which is the epoxy ethane with 8 molecules condensed. The powdered washing has undergone various tests and produced good results. It has good prospects for industrial use.
