Description

Fatty Acids, C16-18 And C18-Unsatd., Bu Esters is a high-purity ester blend derived from natural fatty acids, offering a versatile and consistent chemical intermediate. Its primary value lies in its excellent solvency, lubricity, and compatibility, making it a superior alternative to more volatile or reactive raw materials. This product is essential for formulators and manufacturers in the personal care, lubricant, and polymer industries seeking reliable performance and supply chain stability.

Application

• Plasticizer & Lubricant: Acts as an internal and external lubricant and processing aid in PVC, polyolefins, and other polymer systems, improving flow and mold release.
• Personal Care & Cosmetics: Serves as a key emollient, solvent, and carrier oil in creams, lotions, and makeup, providing a smooth, non-greasy feel.
• Metalworking Fluids: Functions as a lubricity additive and corrosion inhibitor in synthetic and semi-synthetic cutting, grinding, and drawing fluids.
• Industrial Cleaners & Degreasers: Used as a bio-based solvent and coupling agent in heavy-duty industrial and institutional cleaning formulations.
• Textile & Leather Processing: Employed as a softening agent, lubricant, and finishing aid for fibers, yarns, and leather goods.
• Paints & Coatings: Enhances pigment wetting and dispersion, and acts as a flow modifier in various coating systems.
