Description

Fatty Acids, C16-18 And C18-Unsatd., Ethoxylated is a non-ionic surfactant derived from the ethoxylation of a blend of saturated and unsaturated C16-C18 fatty acids. This chemical modification imparts excellent emulsifying, dispersing, and wetting properties, making it a versatile intermediate for formulating high-performance industrial and consumer products. It is essential for manufacturers in the personal care, textile processing, agrochemical, and industrial cleaning sectors seeking to enhance the stability and functionality of their end products.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and thickener in creams, lotions, and hair conditioners, providing a smooth texture and stable formulations.
• Textile Processing: Used as a lubricant, softener, and antistatic agent in fiber spinning and fabric finishing to improve handle and processability.
• Industrial & Institutional (I&I) Cleaning: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and floor care products for effective soil removal and emulsification.
• Agrochemical Formulations: Functions as an emulsifier and dispersant in pesticide and herbicide concentrates, ensuring stable tank mixes and improved spray coverage.
• Paints & Coatings: Employed as a grinding aid and pigment dispersant to achieve uniform color distribution and stability in water-based systems.
• Leather Processing: Utilized as a fatliquoring agent to soften leather and improve its tensile strength and durability.

Quality Control

Our Fatty Acids, C16-18 And C18-Unsatd., Ethoxylated is produced under a stringent quality management system. Each batch is tested against critical parameters including hydroxyl value, acid value, saponification value, and water content to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from strong oxidizing agents. For long-term storage, consider using under an inert atmosphere to prevent oxidation of the unsaturated components.
