Description

Methyl Dodecylbenzene Sulfonate is a high-purity anionic surfactant derived from dodecylbenzene. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in demanding formulations. It serves as a critical intermediate and functional additive for manufacturers in the industrial cleaning, textile processing, and agrochemical sectors seeking reliable performance and batch-to-batch consistency.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Textile Processing: Used as a wetting agent, emulsifier, and dye leveling agent in fiber treatment and dye baths.
• Agrochemical Formulations: Acts as an emulsifier and dispersant in pesticide and herbicide concentrates.
• Emulsion Polymerization: Serves as a surfactant in the production of synthetic latexes for paints, coatings, and adhesives.
• Oilfield Chemicals: Employed in drilling muds and oil recovery formulations for its surfactant properties.
• Chemical Intermediate: Used in the synthesis of other specialty surfactants and sulfonated compounds.
