Description

Oxirane, Methyl-, Polymer With Oxirane, Octyl Ether (CAS NO 61827-84-7) is a specialized polyether surfactant derived from propylene oxide and ethylene oxide, capped with an octyl group. This chemical structure provides a unique balance of hydrophobic and hydrophilic properties, making it an effective and versatile non-ionic surfactant and emulsifier. It is primarily utilized in the formulation of industrial and institutional cleaners, agrochemicals, and as a key component in various polymer and coating systems where controlled surface activity is required.

Application

• As a non-ionic surfactant and emulsifier in industrial and institutional (I&I) cleaning formulations.
• As a wetting and dispersing agent in agrochemical formulations such as herbicides and pesticides.
• As a coalescing aid and stabilizer in water-based polymer dispersions and coating systems.
• As a lubricant and processing aid in the production of polyurethane foams and other polymers.
• As a component in metalworking fluids for its emulsifying and surface-wetting properties.
• In the formulation of textile auxiliaries for scouring, dyeing, and finishing processes.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Octyl Ether is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in parameters such as hydroxyl value, cloud point, and molecular weight distribution. Certificates of Analysis (COA) documenting purity and key specifications are available upon request to support your quality assurance protocols.

Storage

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