Description

Polyethylene Glycol tert-Octylphenyl Ether is a high-performance nonionic surfactant belonging to the alkylphenol ethoxylate family, widely recognized for its excellent emulsifying, wetting, and dispersing properties. Its unique structure provides a critical balance between hydrophilic and lipophilic characteristics, making it a versatile processing aid and stabilizer in demanding industrial formulations. This chemical is essential for manufacturers in sectors such as agrochemicals, textiles, paints, and industrial cleaning, where reliable surfactant performance directly impacts product efficacy and stability.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide concentrates (EC, EW) and adjuvant systems to enhance spray coverage and active ingredient penetration.
• Industrial & Institutional (I&I) Cleaning: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and textile scouring agents due to its robust performance in alkaline conditions.
• Paints & Coatings: Used as a pigment dispersant and grinding aid to improve color development, stability, and application properties in water-based and solvent-based systems.
• Textile Processing: Functions as a leveling agent, dye dispersant, and scouring aid in dyeing and finishing operations to ensure uniform color and fabric quality.
• Metalworking Fluids: Employed as an emulsifier in soluble oils and semi-synthetic coolants to provide stable emulsions and lubricity.
• Pulp & Paper Industry: Utilized in de-inking processes and as a dispersant for controlling pitch and stickies.
• Oilfield Chemicals: Applied in drilling mud formulations and demulsifiers for crude oil treatment.
• Polymerization: Acts as an emulsifier and stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. For long-term storage, consider using under an inert atmosphere to prevent oxidation. Keep container tightly sealed when not in use to minimize moisture absorption.
