Description

Poly(Oxy-1,2-Ethanediyl),.Alpha.-Hydro-.Omega.-Hydroxy-, Mono-C11-13-Branched Alkyl Ethers, Phosphates, Potassium Salts is a specialized anionic surfactant belonging to the phosphate ester class, valued for its excellent emulsifying, wetting, and dispersing properties. This compound is particularly significant for its compatibility with a wide pH range and its effectiveness in high-electrolyte formulations where other surfactants may fail. It is a critical ingredient for formulators in the industrial cleaning, agrochemical, textile, and personal care industries seeking robust performance and enhanced stability.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary emulsifier and wetting agent in heavy-duty alkaline cleaners, degreasers, and metalworking fluids.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC, EW formulations) to ensure stable emulsions upon dilution.
• Textile Processing: Serves as a lubricant, antistatic agent, and dye leveling assistant in fiber and fabric treatment baths.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifier in rinse-off products like shampoos and body washes, offering good foam and skin feel.
• Paints & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as an emulsifier and rheology modifier.
