Description

Bis(2-Ethylhexyl) 2-Hydroxyethyl Phosphate is a specialized organophosphorus compound valued for its unique combination of surfactant and chelating properties. This chemical is a critical performance additive, functioning as an effective emulsifier, dispersant, and metal ion sequestrant in demanding formulations. It is primarily needed by manufacturers in the lubricant, metalworking fluid, textile processing, and personal care industries where stability and multi-functional activity are required.

Application

• Lubricant & Grease Additive: Acts as an anti-wear agent, corrosion inhibitor, and emulsifier in synthetic and semi-synthetic lubricants and metalworking fluids.
• Textile Processing: Used as a leveling agent, emulsifier, and antistatic agent in fiber lubricants and dyeing processes.
• Personal Care & Cosmetics: Functions as an emulsifier and stabilizer in creams, lotions, and hair care products, offering mildness and compatibility.
• Industrial Cleaners: Serves as a surfactant and chelating agent in heavy-duty degreasers and alkaline cleaning formulations.
• Plastic & Polymer Additive: Employed as an internal lubricant, antistatic agent, and processing aid in PVC and other polymer systems.
• Hydraulic & Fire-Resistant Fluids: Utilized as a key component in certain types of fire-resistant hydraulic fluids and specialty industrial fluids.
