  • Applications

    Diisobutyl Sodium Sulfosuccinate (CAS 127-39-9) is used primarily as an anionic surfactant and emulsifier, also functioning as a wetting agent and dispersant for pigment systems in various formulations. In cosmetics and personal care, it serves as a mild surfactant and emulsifier in cleansing and skincare products. In household and industrial cleaners, it enhances cleaning performance and supports dispersion of actives. In coatings and inks, it facilitates pigment wetting and stabilizes dispersions. In polymers and plastics processing, it acts as an emulsifier and stabilizer in emulsions and polymerization media. In adhesives and sealants, it is used as a surfactant additive to improve substrate wetting and dispersion. In agriculture, it can be used as a surfactant adjuvant in spray formulations to improve coverage. Subject to local regulations and formulation limits.
