Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Butyl-.Omega.-(Octyloxy)- is a non-ionic surfactant belonging to the class of alkyl-terminated polyethylene glycol (PEG) ethers. This compound is valued for its excellent surface-active properties, acting as an effective emulsifier, wetting agent, and dispersant in complex formulations. It is primarily utilized in the production of industrial lubricants, coatings, agrochemicals, and personal care products where controlled hydrophobicity and stability are required.

Application

• As a key emulsifier and stabilizer in water-based industrial lubricants and metalworking fluids.
• As a wetting and dispersing agent in pesticide and herbicide formulations for improved foliar adhesion and efficacy.
• As a co-emulsifier and viscosity modifier in coatings, inks, and adhesive systems.
• In the synthesis of specialty polymers and resins as a reactive intermediate or modifier.
• As a surfactant component in institutional and industrial cleaning products.
• In personal care applications, such as creams and lotions, for its emollient and solubilizing properties (subject to grade suitability and regulatory approval).

Quality Control

Our Poly(Oxy-1,2-Ethanediyl), .Alpha.-Butyl-.Omega.-(Octyloxy)- is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent performance characteristics such as hydroxyl value, average molecular weight, and cloud point. A comprehensive Certificate of Analysis (COA) detailing 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, and well-ventilated area at room temperature (15-25°C/59-77°F). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
