Description

Tetraethyleneglycol Monododecyl Ether is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether family. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in a wide range of industrial formulations. It is a critical ingredient for manufacturers in the personal care, agrochemical, textile, and industrial cleaning sectors seeking reliable performance and process stability.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, and hair care products, providing stable oil-in-water emulsions.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates to enhance spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and floor care products for superior detergency.
• Textile Processing: Functions as a leveling agent, dye dispersant, and scouring aid in textile manufacturing and finishing processes.
• Paints & Coatings: Employed as a pigment wetting and grinding aid to improve color development and dispersion stability in aqueous systems.
• Polymerization: Can be utilized as an emulsifier in emulsion polymerization processes for the production of synthetic latexes.
