Description

Octoxynol-9 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, widely recognized for its potent surface-active and detergent properties. Its primary value lies in its exceptional ability to reduce surface tension, emulsify oils, and solubilize a wide range of compounds, making it a versatile processing aid. This chemical is essential for manufacturers in the pharmaceutical, personal care, agrochemical, and industrial cleaning sectors who require a reliable and effective surfactant for formulation development.

Application

• Pharmaceutical & Biotech: Used as a solubilizing agent, emulsifier, and wetting agent in topical formulations, medicated creams, and as a critical component in cell culture media and diagnostic reagents.
• Personal Care & Cosmetics: Functions as a primary surfactant and emulsifier in shampoos, liquid soaps, intimate hygiene products, and spermicidal creams, where its cleansing and foaming properties are utilized.
• Agrochemical Formulations: Acts as an effective wetting agent, dispersant, and emulsifier in pesticides, herbicides, and fungicides to enhance spray coverage and active ingredient penetration.
• Industrial & Institutional Cleaning: Serves as a key ingredient in heavy-duty cleaners, degreasers, and detergent formulations for hard surface cleaning in food processing, manufacturing, and healthcare facilities.
• Textile & Leather Processing: Employed as a scouring agent, dye leveling agent, and wetting agent to improve processing efficiency and final product quality.
• Paints & Coatings: Used as a dispersant and emulsifier in latex paints and coating formulations to stabilize pigments and improve application properties.

Quality Control

Our Octoxynol-9 is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified against stringent in-house specifications, which typically include parameters for assay, ethylene oxide content, cloud point, pH, and residue on ignition. While we offer standard technical and pharmaceutical-intermediate grades, we can provide material compliant with relevant monographs upon request. A detailed Certificate of Analysis (COA) accompanies every shipment to guarantee traceability and specification compliance.

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. Under these conditions, the product has excellent shelf stability.
