Description

Sodium Hydroxy(Tridecyloxy)Propanesulphonate is a high-performance anionic surfactant and hydrotrope, known for its excellent solubility and compatibility in concentrated electrolyte solutions. This compound is critical for enhancing the stability, clarity, and viscosity of complex formulations, particularly where high salt tolerance is required. It is an essential ingredient for manufacturers in the industrial & institutional cleaning, agrochemical, and personal care sectors seeking to improve the performance of their concentrated products.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a powerful hydrotrope and coupling agent in high-alkaline, high-electrolyte liquid detergents, dishwashing liquids, and hard surface cleaners to prevent phase separation.
• Agrochemical Formulations: Used as a solubilizer and stabilizer in concentrated pesticide and herbicide solutions (SL, EC, SC formulations) to ensure tank-mix compatibility and long-term storage stability.
• Personal Care Products: Serves as a mild surfactant and viscosity modifier in shampoos, body washes, and other cleansing products, especially in systems containing high levels of salts or actives.
• Textile & Leather Processing: Functions as a wetting agent, dispersant, and leveling agent in dye baths and finishing chemicals to promote even coloration and processing.
• Oilfield Chemicals: Employed in drilling muds and stimulation fluids as a compatibility agent and to control rheology in high-salinity environments.
• Paint & Coating Additives: Enhances pigment dispersion and stabilizes latex emulsions in water-based architectural and industrial coatings.
