Description

Fatty Acids, C18-Unsatd., Dimers, Ethoxylated Propoxylated is a high-performance, non-ionic surfactant derived from unsaturated C18 fatty acid dimers. This compound is engineered to provide excellent emulsification, wetting, and dispersing properties, making it a versatile intermediate for demanding formulations. It is particularly valuable for industries requiring robust surfactants with enhanced solubility and stability profiles. Key sectors include industrial lubricants, textile processing, agrochemicals, and personal care products.

Application

• Industrial Lubricants & Metalworking Fluids: Acts as an effective emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and drawing compounds.
• Textile Processing: Used as a scouring agent, lubricant, and softener, providing excellent compatibility with various fiber types.
• Agrochemical Formulations: Serves as a key component in pesticide and herbicide emulsions, improving sprayability and plant adhesion.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifier in creams, lotions, and hair care products, offering good skin feel.
• Paints & Coatings: Employed as a dispersing and grinding aid for pigments, enhancing color development and stability.
• Cleaning & Institutional Products: Provides detergency and foam control in industrial and household cleaners.
• Polymer Additives: Can be used as an internal or external lubricant and processing aid in plastics manufacturing.

Quality Control

Our Fatty Acids, C18-Unsatd., Dimers, Ethoxylated Propoxylated is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as hydroxyl value, acid value, saponification value, and moisture content. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with agreed specifications. We adhere to ISO 9001 standards and can support compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and moisture absorption. Keep away from strong oxidizing agents.
