Description

Bis(15-Methyl-3,6,9,12-Tetraoxahexadecyl) Hydrogen Phosphate is a specialized organophosphate surfactant and chelating agent characterized by its polyether chain structure. This compound is valued for its ability to act as a highly effective emulsifier, dispersant, and metal ion complexing agent in demanding formulations. It is primarily sought by manufacturers in the lubricant additive, agrochemical, and specialty polymer industries where performance under specific conditions is critical.

Application

• Lubricant & Fuel Additive: Functions as a multifunctional additive providing detergency, anti-wear properties, and metal deactivation in synthetic and semi-synthetic lubricants and fuels.
• Agrochemical Formulations: Used as an emulsifier and stabilizer in pesticide and herbicide concentrates to improve dispersion and system compatibility.
• Polymer & Resin Production: Acts as a catalyst or chain transfer agent in polymerization processes, and as a plasticizer or stabilizer in final polymer products.
• Metalworking Fluids: Serves as a corrosion inhibitor and emulsifier in cutting oils, drawing compounds, and other industrial metal treatment fluids.
• Personal Care & Cosmetics: Employed as a mild surfactant and emulsifying agent in high-end cosmetic formulations, such as creams and lotions.
• Industrial Cleaning: Enhances the cleaning power and metal sequestration in industrial and institutional detergent formulations.
