Description

Fatty Acids,C18-Unsatd.,Dimers,Diesters With Polyethylene Glycol CAS NO 68139-61-7 is a high-performance, non-ionic surfactant and emulsifier derived from unsaturated C18 fatty acid dimers esterified with polyethylene glycol. This chemistry provides excellent wetting, dispersing, and solubilizing properties, making it a versatile intermediate for demanding formulations. It is primarily sought after by manufacturers in the personal care, industrial lubricants, textile processing, and agrochemical sectors for its ability to enhance stability and performance.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, and hair conditioners, providing a smooth texture and improved skin feel.
• Industrial Lubricants & Metalworking Fluids: Serves as an effective emulsifier and corrosion inhibitor in soluble oils and synthetic coolants.
• Textile Processing: Used as a softening agent, lubricant, and antistatic agent in fiber spin finishes and fabric softeners.
• Agrochemical Formulations: Functions as a key component in pesticide and herbicide emulsions, enhancing sprayability and plant adhesion.
• Paints & Coatings: Employed as a dispersing agent for pigments and fillers, improving grind efficiency and final product stability.
• Plastics & Polymers: Acts as an internal and external lubricant and mold release agent during polymer processing.

Quality Control

Our Fatty Acids,C18-Unsatd.,Dimers,Diesters With Polyethylene Glycol is produced under a stringent quality management system. Each batch undergoes rigorous testing to ensure consistency in key parameters such as acid value, saponification value, hydroxyl value, and viscosity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

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.
