Description

Sulfosuccinic Acid, Sodium Salt is a versatile anionic surfactant and intermediate derived from succinic acid. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in aqueous systems. It serves as a critical raw material for manufacturers in the personal care, textile, and industrial cleaning sectors, where consistent quality and reliable supply are paramount.

Application

• Surfactant & Wetting Agent: A key component in high-performance industrial and institutional cleaners, offering superior surface penetration.
• Personal Care Formulations: Used in shampoos, body washes, and facial cleansers for its mildness and foaming characteristics.
• Textile Processing: Acts as a leveling and dispersing agent in dyeing and finishing operations to ensure uniform color.
• Paper & Pulp Industry: Employed as a dispersant and de-inking agent to improve pulp processing and paper quality.
• Emulsion Polymerization: Serves as a stabilizer and emulsifier in the production of synthetic latexes and polymers.
• Agricultural Adjuvants: Enhances the spreading and absorption of pesticides and herbicides on plant surfaces.
• Metal Treatment & Plating: Functions as a wetting and brightening agent in electroplating baths and surface treatment solutions.
