Description

tert-Butylphenol Oxyethylated is a nonionic surfactant belonging to the alkylphenol ethoxylate family, synthesized by the reaction of tert-butylphenol with ethylene oxide. This versatile chemical intermediate is valued for its excellent surface-active properties, including detergency, wetting, and emulsification. It is essential for formulators and manufacturers in industries such as agrochemicals, industrial cleaning, textiles, and personal care, where stable emulsions and effective dispersion are required.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates (ECs, SCs).
• Industrial & Institutional (I&I) Cleaners: Provides superior wetting and detergency in heavy-duty degreasers and hard surface cleaners.
• Textile Processing: Used as a scouring, leveling, and dyeing assistant to improve process uniformity.
• Metalworking Fluids: Functions as an emulsifier and lubricity agent in coolants and drawing compounds.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid to enhance color development and stability.
• Personal Care: Employed as an emulsifier and solubilizer in select rinse-off products.

Quality Control

Our tert-Butylphenol Oxyethylated is manufactured under a strict quality management system. Each batch is tested against key parameters to ensure consistent performance, including hydroxyl value, ethylene oxide content, and cloud point. Certificates of Analysis (COA) documenting purity, physical properties, and conformance to agreed specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
