Description

Sodium Octylbenzene Sulfonate is a high-performance anionic surfactant derived from the sulfonation of octylbenzene. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in aqueous systems. It serves as a critical ingredient for formulators in the industrial cleaning, textile processing, and agrochemical sectors, where reliable surface activity is required.

Application

• Primary surfactant and wetting agent in industrial and institutional (I&I) cleaning formulations.
• Emulsifier and dispersant in the production of pesticides and agricultural chemical concentrates.
• Key component in textile auxiliaries for scouring, dyeing, and finishing processes.
• Intermediate in the synthesis of more complex specialty surfactants.
• Additive in construction chemicals, such as concrete admixtures, to improve workability.
• Foaming and cleansing agent in select industrial-grade personal care products.
