Description

Poly(Oxy-1,2-Ethanediyl), α-Hydro-ω-Hydroxy-, 2-Butyloctyl Phosphat (Mittlerer Eo 4 Mol) is a specialized phosphate ester surfactant derived from a branched 2-butyloctyl alcohol and a short ethoxylate chain. This compound matters for its unique combination of emulsifying, dispersing, and anti-static properties, making it a versatile performance additive. Industries such as lubricants, metalworking fluids, agrochemicals, and coatings rely on this chemical to enhance formulation stability and functionality.

Application

• Lubricant & Grease Additive: Functions as an effective anti-wear agent, friction modifier, and emulsifier in synthetic and semi-synthetic lubricating oils and greases.
• Metalworking Fluids: Serves as a key component in soluble oils and semi-synthetic coolants, providing emulsion stability, lubricity, and corrosion inhibition.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates to improve tank-mix stability and spray application.
• Industrial & Institutional Cleaners: Acts as a surfactant and degreaser in heavy-duty cleaning formulations for hard surfaces and machinery.
• Coatings & Inks: Employed as a dispersing agent for pigments and fillers, improving color development and preventing settling in paints and printing inks.
• Textile Processing: Utilized as a spin finish lubricant and anti-static agent for synthetic fibers during manufacturing.
• Personal Care (Rinse-off products): Can be used as a mild surfactant and emulsifier in select rinse-off cosmetic formulations, subject to compliance.

Quality Control

Our production of this phosphate ester adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as active content, acid value, pH, and moisture level are rigorously tested. A comprehensive Certificate of Analysis (COA) documenting these specifications is provided with every shipment to support your quality assurance and regulatory needs.

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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product performance.
