About FMEE Fatty Methyl Ester Ethoxylates  :

Chemical structure

The chemical structure of the fatty methyl ethoxy ether consists of three main components: long-chain alkyl, methyl ester, and ethoxy. Long-chain alkyl provides hydrophobicity, methyl ester provides hydrophilicity, and the ethoxy group increases the intermolecular interaction force. This special chemical structure enables the fat methyl ethoxyl ether to form micelles in aqueous solution, reduce the surface tension of water, and thus produce wetting, emulsification, solubilization and foaming.

Surface activity

Fat methyl ethoxy ether has good surface activity. It can form micelles in an aqueous solution, which significantly reduces the surface tension of water and enables water and oil to mix. This property makes methyl ester an ideal emulsifier, wetting agent and dispersant.

Hydrophilic and lipophilic

The hydrophilicity and lipophilicity of methyl ester ethoxy ether depend on its chemical structure and composition. In general, with the increase of the carbon chain, the lipophilicity of fat methyl ethoxy ether increases. With the increase of ether bond content, its hydrophilicity increases. This balance of hydrophilicity and lipophilicity enables methyl ester ethoxy ether to act as a bridge at the water-oil interface so as to achieve emulsification, dispersion, and solubilization.

Stability

Fatty methyl ester ethoxy ether has good chemical stability and is not prone to hydrolysis, oxidation and thermal decomposition. However, under strong acid and base or high-temperature conditions, the fatty methyl ethoxy ether may undergo hydrolysis or oxidation reaction, reducing surface activity. Therefore, fat methyl ethoxy ether storage and use conditions should be controlled when using it.

Biodegradability

This allows the fat methyl ethoxy ether to not cause long-term environmental pollution after use. However, to achieve better degradation effects, selecting suitable microbial strains and appropriate degradation conditions is necessary.

Toxicity

Fatty methyl ester ethoxy ether is safe for humans and animals under normal conditions of use. Therefore, when using products containing fatty methyl ethoxy ether, care should be taken to follow safety guidelines and product instructions.

Production Method of  FMEE Fatty Methyl Ester Ethoxylates:

Esterification reaction and etherification reaction

Producing fatty methyl ester ethoxy ether usually involves two main steps: esterification and etherification. In esterification, fatty alcohols react with acids to form fatty acid esters. Commonly used acid catalysts include sulfuric acid, phosphoric acid and acid ion exchange resins. It is necessary to control the temperature, pressure and reaction time during the reaction process to ensure the esterification reaction and the quality of the product. The obtained fatty acid ester is further etherized with ethylene oxide to form the fat methyl ethoxy ether. Etherification is usually carried out in the presence of catalysts, including sodium hydroxide, potassium hydroxide and acid ion exchange resins. In the reaction process, it is necessary to control the temperature, pressure, and feed ratio of ethylene oxide to ensure the etherification reaction and product quality.

Direct etherification

With science and technology, people have developed a direct etherification method to produce fat methyl ester ethoxy ether. This method avoids the traditional two-step process of esterification and etherification. Fatty alcohol and ethylene oxide are etherified directly to produce methyl ester ethoxy ether in one step. The method has the advantages of a simple process, high production efficiency, and environmental friendliness. Commonly used catalysts include sodium hydroxide, potassium hydroxide and acid ion exchange resins. In the reaction process, it is necessary to control the temperature, pressure, and feed ratio of ethylene oxide to ensure the etherification reaction and product quality.

Enzyme catalysis method

Enzyme catalysis is an environmentally friendly method for producing methyl ester ethoxy ether. The method uses enzymes as catalysts to etherize fatty alcohol and ethylene oxide as raw materials to produce fat methyl ethoxy ether. The advantages of the enzyme-catalyzed method are mild reaction conditions, high product purity, and environmental friendliness. Commonly used enzymes include lipase, esterase and glucose oxidase. The enzyme catalysis method can be divided into two types: the one-step method and the two-step method. The one-step method is to mix the fatty alcohol, ethylene oxide, and enzyme and react at a certain temperature and pH conditions to produce the fat methyl ethoxy ether. The two-step process is to esterify the fatty alcohol with ethylene oxide to produce an intermediate and then etherify the intermediate with another ethylene oxide molecule to produce the fat methyl ester ethoxy ether. The disadvantages of enzymatic catalysis are limited sources of enzymes, high cost, and possible specificity limitations for some substrates.

Ion exchange resin method

The ion exchange resin method is new for producing fat methyl ester ethoxy ether. The method uses ion exchange resin as a catalyst and fatty alcohol and ethylene oxide as raw materials for etherification reaction to produce fat methyl ethoxy ether. The advantages of the ion-exchange resin method are that the catalyst can be reused, high product purity, and friendly environmental protection. Common ion exchange resins include strong acidic cation and basic anion exchange resins. The disadvantages of the ion exchange resin method are long reaction time and difficult separation and purification of products.

Application of FMEE Fatty Methyl Ester Ethoxylates:   

Cosmetics and personal care products

In cosmetics and personal care products, the fat methyl ethoxy ether is used as the main ingredient to improve the product's performance and user experience. As an emulsifier, wetting agent, and solubilizer, it helps to disperse the product evenly, stabilize the emulsion, and improve skin sensation. In addition, it is also used in the formulation of makeup products such as lipsticks and eyeshadow to improve the persistence and adhesion of colors.

Detergents and cleaning supplies

Fatty methyl ester ethoxy ether is the main component in detergents and cleaning products and exerts excellent surface activity. It can reduce the surface tension of the water and improve the detergent's wettability and permeability on the stain's surface, thus enhancing the washing effect. In laundry detergent, dish soap, hand sanitizer, and other products, methyl ester ethoxy ether helps to improve the solubility of detergent, foam, and decontamination ability, make clothes cleaner, improve cleaning efficiency and save water consumption.

Paint and coatings manufacturing

In the manufacture of paints and coatings, methyl ester ethoxy ether is used as an emulsifier and wetting agent, which plays a key role in the dispersion and stability of pigments. Using methyl ester ethoxy ether to manufacture paint and coatings helps improve the quality, stability, and construction of coatings and their appearance and protection performance.

Agriculture and plant protection

It can promote the wetting and penetration of pesticides on the surface of plants to improve the control effect of pesticides. In addition, fatty methyl ester ethoxy ether can also be used as a carrier of plant growth regulators to promote plant growth and development. In plant protection products, methyl ester ethoxy ether helps improve product performance and effect.
