Description

Sodium Octoxynol-2 Ethane Sulfonate is a high-performance anionic-nonionic surfactant derived from ethoxylated octylphenol. This compound is valued for its excellent wetting, dispersing, and emulsifying properties, particularly in challenging aqueous systems. It is a critical raw material for formulators in the agrochemical, textile, and industrial cleaning sectors who require robust and stable surfactant performance.

Application

• Agrochemical Formulations: Acts as a key wetting agent and dispersant in suspension concentrates (SC) and wettable powders (WP) for pesticides and herbicides.
• Textile Processing: Used in scouring, dyeing, and finishing baths for its superior wetting and penetrating abilities on synthetic and natural fibers.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty alkaline and acid cleaners, degreasers, and metal treatment solutions.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Oilfield Chemicals: Employed in drilling muds and well stimulation fluids for its emulsification and dispersion characteristics.
• Paint & Coatings: Enhances pigment dispersion and stabilizes aqueous coating systems to prevent settling and improve finish quality.
• Leather Processing: Used in soaking, degreasing, and dyeing stages to ensure uniform chemical penetration and processing.
• Paper & Pulp Industry: Aids in de-inking processes and acts as a dispersant for pigments and fillers in paper coating formulations.

Quality Control

Our Sodium Octoxynol-2 Ethane Sulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with industry specifications. Certificates of Analysis (COA) documenting key parameters such as assay, sulfonate content, and pH are available upon request to support your quality assurance protocols.

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). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
