Description

Tetraethyleneglycol Monodecyl Ether is a high-purity, non-ionic surfactant belonging to the polyoxyethylene alkyl ether family. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, making it a versatile intermediate and performance additive. It is essential for formulators and manufacturers in sectors requiring precise surface activity control, such as agrochemicals, coatings, and industrial cleaning. Consistent quality and reliable supply are critical for maintaining batch-to-batch reproducibility in these demanding applications.

Application

• Agrochemical Formulations: Acts as a key wetting agent, emulsifier, and penetrant in herbicides, insecticides, and fungicides.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaners, and floor care products for its superior detergency.
• Coatings & Inks: Functions as a dispersing and flow control agent in water-based paints, pigment preparations, and printing inks.
• Textile Processing: Employed as a scouring agent, dye leveler, and softener in fabric treatment baths.
• Personal Care & Cosmetics: Serves as a mild surfactant and emulsifier in rinse-off products like shampoos and body washes.
• Metalworking Fluids: Incorporated as an emulsifier and corrosion inhibitor in soluble oils and coolants.
• Polymerization: Utilized as a non-ionic emulsifier and stabilizer in emulsion polymerization processes.
