Description

Neopentyl Glycol Dicaprylate/Dicaprate is a high-performance, synthetic ester derived from neopentyl glycol and a blend of caprylic (C8) and capric (C10) fatty acids. This compound is valued for its exceptional oxidative stability, low volatility, and excellent lubricity, making it a superior base fluid and additive. It is primarily sought after by formulators in the cosmetics, personal care, and lubricant industries for creating stable, high-quality end products.

Application

• Cosmetic & Personal Care Emollient: Used as a non-greasy, fast-absorbing emollient and solvent in skin creams, lotions, sunscreens, and makeup products.
• High-Performance Lubricant Base Stock: Serves as a synthetic base oil for formulating high-temperature, low-pour point lubricants and compressor oils.
• Plasticizer: Acts as a secondary plasticizer and viscosity modifier in polymer systems, including PVC and synthetic rubbers.
• Functional Fluid: Employed in heat transfer fluids, metalworking fluids, and textile processing aids due to its thermal stability.
• Carrier & Solvent: Functions as a carrier for active ingredients and a solvent for fragrances and dyes in various industrial applications.
