Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(Nonylphenyl)-.Omega.-Hydroxy-, Phosphate, Sodium Salt is a specialized anionic surfactant and emulsifier derived from ethoxylated nonylphenol. This compound matters for its unique ability to provide excellent wetting, dispersing, and emulsifying properties in challenging formulations, particularly where compatibility with electrolytes is required. Industrial manufacturers in sectors such as agrochemicals, textiles, and metalworking fluids need this high-performance surfactant to enhance the stability and efficacy of their end products.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates, improving sprayability and plant coverage.
• Textile Processing: Used as a wetting and scouring agent in dyeing and finishing baths to ensure even color penetration and soil removal.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and coolants for machining and grinding operations.
• Industrial & Institutional Cleaners: Provides effective emulsification of oils and greases in heavy-duty alkaline and acidic cleaning formulations.
• Paint & Coating Additives: Functions as a pigment dispersant and grinding aid to improve color development and stability in aqueous systems.
• Paper & Pulp Industry: Utilized as a de-inking agent and dispersant to aid in the removal of inks and contaminants during recycling processes.
