Description

Sulfonic Acids, C13-18-sec-Alkane, Sodium Salts is a high-performance anionic surfactant derived from secondary alkane sulfonates, offering excellent wetting, emulsifying, and foaming properties. This compound is valued for its robust performance in demanding formulations, particularly where high electrolyte tolerance and stability are required. It is a critical raw material for manufacturers in the detergent, personal care, and industrial cleaning sectors seeking effective and reliable surface-active agents.

Application

• Detergent & Cleaner Formulations: Primary surfactant in liquid and powder laundry detergents, dishwashing liquids, and all-purpose cleaners.
• Personal Care Products: Key ingredient in shampoos, shower gels, and hand soaps for its mildness and good lathering characteristics.
• Industrial & Institutional (I&I) Cleaning: Used in floor cleaners, degreasers, and vehicle wash formulations due to its high tolerance for hard water and alkalies.
• Textile & Leather Processing: Acts as a wetting agent, emulsifier, and leveling agent in dyeing and finishing baths.
• Emulsion Polymerization: Serves as an effective emulsifier and stabilizer in the production of synthetic rubbers, plastics, and polymer dispersions.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
