Description

Sodium 4-((2-Ethylhexyl)Oxy)-4-Oxo-2-Sulfonatobutanoate is a high-purity anionic surfactant and specialty chemical intermediate. Its molecular structure, featuring both a sulfonate group and an ester linkage, provides excellent wetting, emulsifying, and dispersing properties in aqueous systems. This compound is essential for formulators in industries such as agrochemicals, coatings, and personal care, where performance and batch-to-batch consistency are critical. We supply this material with a focus on reliable quality and supply chain security for global industrial partners.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticide concentrates and suspension concentrates (SC).
• Coatings and Inks: Used as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Personal Care Products: Serves as a mild surfactant and emulsifier in select cosmetic and toiletry formulations.
• Industrial Cleaners: Functions as a hydrotrope and coupling agent to enhance the solubility of other surfactants in liquid detergent blends.
• Textile Processing: Employed as a leveling agent and dye dispersant in dyeing and finishing operations.
• Polymerization: Can be utilized as an emulsifier in certain emulsion polymerization processes for synthetic rubbers and plastics.
