Sodium Fatty Acid Methyl Ester Sulfonate, commonly abbreviated as MES, is a type of environmentally friendly anionic surfactant derived from natural renewable resources such as vegetable oils or animal fats. It typically appears as a white to light yellow powder or flake solid, with good water solubility, excellent detergency, emulsifying property and foam stability.

Core Characteristics

Performance AdvantagesMES stands out for its strong resistance to hard water, maintaining stable cleaning performance even in water with high calcium and magnesium ion content without the need for additional builders. It has a mild formula, with lower irritation to the skin compared with traditional petrochemical-based surfactants, making it suitable for mild cleaning products. In addition, it features excellent biodegradability, breaking down rapidly in the natural environment without causing persistent pollution, which aligns with the global trend of green and sustainable development.

Safety TraitsThis surfactant has low toxicity and meets the safety standards of daily chemical products in most countries and regions. Under normal usage concentrations, it does not cause skin dryness, tightness or irritation, and is friendly to both the human body and the ecological environment.

Main Application Fields

Household Cleaning ProductsMES is a key raw material for formulating high-efficiency and environmentally friendly laundry powder, laundry detergent and dishwashing liquid. It can effectively remove various stains such as oil stains, food residues and dirt on clothes and tableware, and produce rich and stable foam that is easy to rinse off, avoiding residue on fabrics or tableware surfaces. It is especially suitable for manufacturing laundry products for baby clothes and sensitive skin, as well as low-phosphorus or phosphorus-free cleaning formulations.

Personal Care ProductsIn the personal care field, MES is used in mild hand sanitizers, body washes and facial cleansers. Its mild cleaning ability can remove dirt and excess oil on the skin surface without damaging the skin's natural barrier, helping to maintain skin moisture and a comfortable state. It also shows good compatibility with other mild surfactants, and can be compounded to enhance the overall performance of products.

Industrial and Textile ApplicationsIn the textile industry, MES serves as a scouring agent, wetting agent and leveling agent in the dyeing and finishing process. It can effectively remove sizing agents, waxes and impurities on fiber surfaces, improve the wettability of fibers, and promote uniform dyeing of fabrics, thus enhancing the quality of textile products. In the industrial cleaning sector, it is used to prepare metal cleaners and industrial degreasers, playing a role in removing oil stains and dirt on the surface of equipment.

Other FieldsMES is applied in the production of agricultural pesticide emulsifiers, helping to disperse pesticide active ingredients evenly in water to form stable suspensions, which improves the adhesion and permeability of pesticides on crop surfaces. It can also be used in the formulation of water-based coatings and inks, acting as a dispersant to promote the uniform dispersion of pigments and fillers, and improve the smoothness and finish of coating films and printed products
