Description

Sodium Didodecylbenzenesulphonate is a high-purity anionic surfactant derived from dodecylbenzene. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in demanding industrial formulations. It serves as a critical performance additive for manufacturers in the agrochemical, textile, and polymer industries seeking reliable and consistent surfactant performance.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticides, herbicides, and fungicides.
• Textile Processing: Used as a wetting agent and detergent in scouring, dyeing, and finishing operations.
• Polymer & Rubber Industry: Functions as an emulsifier in emulsion polymerization (e.g., for SBR, ABS) and as a processing aid.
• Industrial & Institutional (I&I) Cleaners: A core component in heavy-duty degreasers and cleaning concentrates.
• Oilfield Chemicals: Employed in drilling mud formulations and as an additive for enhanced oil recovery.
• Leather Processing: Used in tanning and fatliquoring processes for improved penetration and uniformity.
