Description

Dioctylsulphosuccinate is a high-purity anionic surfactant, also known as dioctyl sodium sulfosuccinate (DSS). This compound is valued for its excellent wetting, emulsifying, and dispersing properties in both aqueous and non-aqueous systems. It is a critical raw material for formulators in the pharmaceutical, agrochemical, and specialty chemical industries seeking reliable performance and consistent quality.

Application

• Pharmaceutical Excipient: Widely used as a wetting agent and solubilizer in tablet and capsule formulations to enhance drug dissolution.
• Agrochemical Formulations: Serves as a key surfactant in pesticides, herbicides, and fungicides to improve spreading and penetration on plant surfaces.
• Industrial Emulsifier: Employed in the production of polymer emulsions, latex, and coatings for stable particle dispersion.
• Textile Processing: Acts as a wetting and leveling agent in dyeing and finishing processes to ensure uniform color application.
• Personal Care Products: Used in creams, lotions, and topical preparations for its emulsifying and skin-feel enhancement properties.
• Oilfield Chemicals: Functions as an emulsifier and viscosity modifier in drilling muds and other petroleum industry fluids.
