Description

Sodium Undecylbenzenesulfonate is a high-purity anionic surfactant derived from linear alkylbenzene. This compound is valued for its excellent wetting, foaming, and emulsifying properties, making it a critical component in formulating high-performance cleaning and industrial products. It is essential for manufacturers in the detergent, agrochemical, textile, and oilfield chemical industries seeking reliable and effective surface-active agents.

Application

• Primary surfactant in liquid and powder detergent formulations for enhanced cleaning power.
• Emulsifier and wetting agent in agricultural chemical products such as pesticides and herbicides.
• Key ingredient in industrial and institutional (I&I) cleaners for hard surface cleaning.
• Foaming and dispersing agent in the textile processing industry.
• Additive in enhanced oil recovery (EOR) and drilling fluid formulations.
• Intermediate in the synthesis of specialty surfactants and sulfonated polymers.

Quality Control

Our Sodium Undecylbenzenesulfonate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for active matter content, sulfonation efficiency, and impurity profiles. Certificates of Analysis (COA) documenting purity, assay, and physical parameters are available for every shipment to guarantee consistency and compliance with your formulation requirements.

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); keep the container tightly sealed when not in use to prevent caking and degradation due to moisture absorption. Keep away from strong oxidizing agents.
