Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Tridecyl-.Omega.-Hydroxy-, Phosphate, Sodium Salt is a specialized nonionic surfactant and anionic phosphate ester blend, valued for its excellent emulsifying, wetting, and dispersing properties. This unique chemistry provides superior performance in demanding formulations where stability and compatibility are critical. It is an essential ingredient for manufacturers in the agrochemical, textile, and industrial cleaning sectors seeking high-efficiency surface-active agents.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates (EC, SC, EW) and adjuvant systems, enhancing spray coverage and active ingredient efficacy.
• Textile Processing: Used as a wetting agent, lubricant, and antistatic agent in fiber preparation, dyeing, and finishing baths to improve process uniformity.
• Industrial & Institutional (I&I) Cleaning: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and alkaline formulations, offering high detergency and stability in hard water.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid, improving color development and stability in water-based architectural and industrial coatings.
• Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and drawing compounds.
• Personal Care: Can be utilized in rinse-off products like shampoos and body washes as a mild secondary surfactant and foam booster.
