Description

Fatty Acids, C8-10, 1,2-Ethanediylbis(Oxy-2,1-Ethanediyl) Esters is a synthetic ester derived from caprylic (C8) and capric (C10) fatty acids, functioning as a versatile non-ionic surfactant and emollient. This compound is valued for its excellent solvency, low viscosity, and skin-friendly properties, making it a key ingredient in high-performance formulations. It is primarily sought by manufacturers in the personal care, cosmetics, and industrial lubricant sectors for its stability and compatibility with a wide range of ingredients.

Application

• Personal Care & Cosmetics: Acts as a premium emollient, solubilizer, and carrier oil in skin creams, lotions, sunscreens, and makeup products.
• Industrial Lubricants & Metalworking Fluids: Serves as a synthetic base oil or additive, providing lubrication, corrosion inhibition, and thermal stability.
• Plasticizers & Polymer Additives: Used as a secondary plasticizer or processing aid to improve flexibility and workability in various polymer systems.
• Textile & Leather Processing: Functions as a softening agent, lubricant, and finishing agent for fibers and leather goods.
• Cleaning & Detergent Formulations: Employed as a surfactant and degreaser in industrial and institutional cleaning products.
• Agricultural Adjuvants: Used as an emulsifier and spreader in pesticide and herbicide formulations to enhance efficacy.
