Description

Polyoxyethylene 10 Tridecyl Ether is a nonionic surfactant belonging to the alkylphenol ethoxylate family, specifically a tridecyl alcohol ethoxylate with an average of 10 moles of ethylene oxide. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in aqueous systems. It is a critical ingredient for formulators in the industrial cleaning, agrochemical, textile, and paint & coatings sectors seeking reliable performance and stability.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary surfactant and wetting agent in heavy-duty degreasers, floor cleaners, and metalworking fluids.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates to ensure stable emulsion formation upon dilution.
• Textile Processing: Serves as a scouring, leveling, and wetting agent in dyeing and finishing operations to improve process uniformity.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid to prevent agglomeration and ensure color consistency.
• Paper & Pulp Industry: Employed as a de-inking agent and dispersant in pulp processing and paper coating formulations.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as an emulsifier and viscosity modifier.
