Description

Butanedioic Acid, Sulfo-, 1,4-Diisooctyl Ester, Sodium Salt is a high-performance anionic surfactant and wetting agent derived from succinic acid. This compound is valued for its excellent emulsifying, dispersing, and solubilizing properties in demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, inks, agrochemical, and textile processing industries where stable emulsions and effective surface wetting are critical.

Application

• Coatings & Inks: Acts as a highly effective pigment dispersant and grinding aid, improving color development and stability in solvent-based and high-solids systems.
• Agrochemical Formulations: Serves as a key emulsifier and wetting agent in pesticide and herbicide concentrates (EC, SC, EW), enhancing spray coverage and biological efficacy.
• Textile Processing: Used in dyeing and finishing operations to improve dye leveling, penetration, and the overall uniformity of color application.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.
• Industrial Cleaners: Provides powerful wetting and emulsification for degreasers and solvent-based cleaning products used in automotive and metal parts cleaning.
• Polymerization: Can be employed as an emulsifier in specific emulsion polymerization processes for synthetic rubbers and plastics.
