Description

Nonoxynol-3 is a non-ionic surfactant belonging to the alkylphenol ethoxylate family, specifically a polyethylene glycol ether of nonylphenol with an average of 3 moles of ethylene oxide. This compound is valued for its effective wetting, emulsifying, and dispersing properties in aqueous systems. It serves as a critical intermediate and functional additive for formulators in the industrial cleaning, agrochemical, textile, and coatings sectors seeking reliable performance at a lower hydrophilic-lipophilic balance (HLB).

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key surfactant and wetting agent in heavy-duty degreasers, floor cleaners, and metalworking fluids.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates to improve tank mix stability and spray application.
• Textile Processing: Functions as a scouring agent, dye leveler, and wetting agent in fabric preparation and dyeing processes.
• Coatings & Inks: Employed as a dispersant and flow aid to stabilize pigment suspensions and improve substrate wetting.
• Pulp & Paper Industry: Serves as a de-inking agent and dispersant in paper recycling and pulp processing.
• Intermediate Synthesis: Used as a chemical building block for the production of other specialty surfactants and derivatives.

Quality Control

Our Nonoxynol-3 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including hydroxyl value, cloud point, and ethylene oxide distribution. A Certificate of Analysis (COA) documenting purity, physical properties, and conformance to agreed specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperatures (15-25°C). Keep away from strong oxidizing agents. Under these conditions, the product is typically stable for at least 24 months from the date of manufacture.
