Description

Oxirane, Methyl-, Polymer With Oxirane, Octadecanoate is a polymeric chemical compound derived from the reaction of propylene oxide and ethylene oxide with stearic acid. This versatile product serves as a crucial nonionic surfactant and emulsifier, valued for its ability to modify surface tension and stabilize formulations. It is primarily sought by manufacturers in the personal care, coatings, textile, and industrial cleaning sectors for its excellent wetting, dispersing, and solubilizing properties.

Application

• As a primary emulsifier and stabilizer in cosmetic and personal care creams, lotions, and ointments.
• Key surfactant component in industrial and institutional cleaning formulations and detergents.
• Used as a dispersing agent and wetting agent in water-based paints, coatings, and inks.
• Processing aid and antistatic agent in the textile and fiber manufacturing industry.
• Emulsifier and lubricant in metalworking fluids and industrial lubricants.
• Intermediate in the synthesis of specialty esters and other polymeric materials.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Octadecanoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance and meets agreed-upon specifications. A Certificate of Analysis (COA) detailing key parameters such as hydroxyl value, saponification value, and moisture content is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

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 material is hygroscopic (moisture-sensitive); ensure containers are kept sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
