Fatty acid methyl ester ethoxylate (FMEE) is widely used in industrial and household cleaning products due to its excellent surfactant properties. It is particularly effective in degreasing applications, making it a key ingredient in heavy-duty cleaners for removing oil, grease, and dirt from surfaces. Its ability to emulsify and disperse oils makes it suitable for use in metal cleaning, textile processing, and automotive cleaning solutions.

In the textile industry, FMEE is utilized as a wetting and scouring agent, helping to remove impurities from fabrics during processing. It is also employed in the formulation of detergents and dishwashing liquids, where it enhances cleaning efficiency and foam stability. Additionally, FMEE is valued in agricultural applications as an adjuvant in pesticide formulations, improving the spread and adhesion of active ingredients on plant surfaces. Its biodegradability and low toxicity make it an environmentally friendly choice for various applications.
