Description

Sodium 4-n-Octylbenzenesulfonate is a high-purity anionic surfactant derived from linear alkylbenzene sulfonic acid. This compound is valued for its excellent wetting, emulsifying, and foaming properties in aqueous systems. It is a critical raw material for formulators in the industrial cleaning, agrochemical, and textile processing sectors who require consistent performance and reliable supply.

Application

• Primary surfactant and wetting agent in industrial and institutional (I&I) cleaning formulations.
• Emulsifier and dispersant in the production of agricultural chemicals, including pesticides and herbicides.
• Key component in textile auxiliaries for scouring, dyeing, and finishing processes.
• Foaming and cleansing agent in specialized technical-grade detergent blends.
• Intermediate in the synthesis of other specialty surfactants and sulfonated compounds.
• Additive in emulsion polymerization processes to stabilize polymer particles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
