Description

Sodium 3-(1,3-Dimethylbutoxy)-2-Hydroxypropanesulphonate is a specialized anionic surfactant and hydrotrope, valued for its excellent solubility and stability in high-electrolyte and alkaline formulations. This compound is engineered to enhance the performance and clarity of concentrated liquid products by preventing phase separation and viscosity build-up. It is a critical component for formulators in the detergent, personal care, and industrial cleaning sectors seeking robust, multi-functional additives.

Application

• Liquid Detergent & Cleaner Formulations: Acts as a primary hydrotrope and coupling agent to maintain clarity and stability in concentrated heavy-duty liquids, hard surface cleaners, and dishwashing liquids.
• Personal Care Products: Used in shampoos, body washes, and liquid soaps as a viscosity modifier and solubilizer for fragrances and active ingredients.
• Industrial & Institutional (I&I) Cleaners: Enhances the efficacy of alkaline and chlorinated cleaners, including dairy, food processing, and transportation cleaning systems.
• Agricultural Formulations: Serves as a stabilizer and compatibility agent in pesticide and herbicide concentrates.
• Textile & Leather Processing: Functions as a wetting agent, dispersant, and leveling agent in dyeing and finishing baths.
• Coatings & Paints: Improves pigment dispersion and stability in water-based coating systems.
