Description

2-Hydroxyethyl Methyl Hydrogen Phosphate is an organophosphorus compound that serves as a versatile intermediate and functional additive. Its unique structure, combining a phosphate ester group with hydroxyl and methyl functionalities, makes it valuable for modifying surface properties and chemical reactivity. This chemical is essential for manufacturers in sectors requiring specialized surfactants, flame retardants, and metal treatment agents, where precise molecular architecture is critical for performance.

Application

• Surfactant & Emulsifier Intermediate: Used in the synthesis of specialized anionic surfactants for industrial and institutional cleaning formulations.
• Flame Retardant Synergist: Acts as a component in flame-retardant systems for polymers, textiles, and coatings, enhancing char formation.
• Metal Surface Treatment: Employed in metalworking fluids and corrosion inhibitor formulations for ferrous and non-ferrous metals.
• Lubricant & Anti-wear Additive: Functions as an extreme pressure (EP) additive and friction modifier in synthetic lubricants and hydraulic fluids.
• Textile & Fiber Processing: Used as an antistatic agent and softening auxiliary in fiber production and fabric finishing.
• Paper & Pulp Industry: Serves as a dispersant and processing aid in paper coating and pigment slurry formulations.
• Personal Care Ingredients: Utilized as a precursor for mild surfactants in cosmetic and personal care products.
• Chemical Synthesis Intermediate: A key building block for further organic synthesis of more complex phosphate esters and derivatives.
