Description

Disodium 4-(Octadecenyl) 2-Sulphonatosuccinate is a high-performance anionic surfactant belonging to the succinate sulfonate ester class, valued for its excellent emulsifying, dispersing, and wetting properties. Its unique molecular structure provides superior mildness and compatibility, making it a preferred ingredient in formulations requiring high efficacy with low irritation potential. This compound is essential for manufacturers in the personal care, household & industrial cleaning, and textile processing industries seeking advanced surface-active performance.

Application

• Personal Care Formulations: Acts as a primary or secondary surfactant in mild shampoos, body washes, facial cleansers, and baby care products.
• Household & Industrial Cleaners: Used in liquid dishwashing detergents, hard surface cleaners, and industrial degreasers for its superior grease-cutting and foaming properties.
• Textile Processing: Serves as an effective wetting agent, dispersant, and emulsifier in dyeing and finishing processes.
• Emulsion Polymerization: Functions as a critical emulsifier and stabilizer in the production of synthetic latexes for paints, coatings, and adhesives.
• Agricultural Adjuvants: Enhances the spreading and absorption of pesticides and herbicides on plant surfaces.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery formulations as a surfactant and viscosity modifier.
