Description

Disodium 2-Ethylhexyl Phosphate is an organophosphate salt widely recognized for its surfactant and chelating properties. This compound is valued for its ability to modify surface tension and sequester metal ions in complex formulations. It serves as a critical functional additive for manufacturers in the lubricant, metalworking fluid, textile processing, and personal care industries, where performance and stability are paramount.

Application

• Metalworking Fluids & Lubricants: Acts as an effective anti-wear additive, corrosion inhibitor, and emulsifier in synthetic and semi-synthetic fluids.
• Textile Processing: Used as a wetting agent, detergent, and antistatic agent in fiber treatment and dyeing processes.
• Personal Care & Cosmetics: Functions as an emulsifying and stabilizing agent in creams, lotions, and hair care products.
• Industrial Cleaners: Serves as a key surfactant and builder in heavy-duty alkaline and acid cleaning formulations.
• Paints & Coatings: Employed as a dispersing agent for pigments and fillers to improve stability and application properties.
• Plastic & Polymer Processing: Acts as an internal lubricant and antistatic agent during extrusion and molding.
• Agricultural Formulations: Used as an adjuvant and emulsifier in pesticide and herbicide concentrates.
• Oilfield Chemicals: Applied as a scale inhibitor and surfactant in drilling and production fluids.
