Description

3-[(2-Ethylhexyl)Oxy]-2-Hydroxy-1-Propanesulfonic Acid Sodium Salt is a high-purity, anionic surfactant and specialty chemical intermediate valued for its excellent wetting, emulsifying, and solubilizing properties. This compound is critical for formulators requiring a stable, water-soluble component with a branched hydrophobic chain to modify surface tension and enhance compatibility in complex mixtures. It is primarily needed by manufacturers in the personal care, agrochemical, textile, and industrial cleaning sectors for producing high-performance formulations.

Application

• Personal Care & Cosmetics: Used as a mild surfactant, emulsifier, and viscosity modifier in shampoos, body washes, facial cleansers, and other skincare products.
• Agrochemical Formulations: Acts as a wetting agent, dispersant, and penetrant in pesticide and herbicide concentrates and emulsifiable concentrates (ECs).
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant in hard surface cleaners, degreasers, and detergent formulations for its oil-emulsifying power.
• Textile Processing: Employed as a wetting and leveling agent in dyeing and finishing processes to ensure uniform color application.
• Coatings & Inks: Functions as a dispersing and stabilizing agent in pigment preparations and water-based coating systems.
• Polymerization: Can be utilized as an emulsifier or stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.
