Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(2-Ethylhexyl)-.Omega.-Hydroxy-, Phosphate is a specialized nonionic surfactant and phosphate ester, widely recognized for its excellent emulsifying, dispersing, and wetting properties. This compound is valued for its ability to function effectively under demanding conditions, including high electrolyte environments and across a wide pH range. It is a critical raw material for formulators in the agrochemical, textile, metalworking, and personal care industries seeking robust performance and formulation stability.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates (ECs, SCs) and adjuvant systems, enhancing spray coverage and active ingredient efficacy.
• Metalworking Fluids: Serves as an effective emulsifier and lubricity agent in synthetic and semi-synthetic cutting fluids, coolants, and drawing compounds.
• Textile Processing: Used as a wetting agent, lubricant, and antistatic agent in fiber spinning, dyeing, and finishing operations.
• Industrial & Institutional Cleaners: Functions as a surfactant and detergent builder in heavy-duty alkaline and acid cleaners, offering good hard water tolerance.
• Personal Care: Employed as an emulsifier and solubilizer in select cosmetic and toiletry formulations, such as creams and lotions.
• Paints & Coatings: Utilized as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Paper & Pulp Industry: Applied as a dispersant and deinking agent in pulp processing and paper coating formulations.
