Description

Propylene Glycol Dicaprylate/Dicaprate is a high-purity, synthetic diester derived from propylene glycol and a blend of caprylic and capric fatty acids. This versatile emollient and solvent is prized for its excellent skin feel, low viscosity, and exceptional oxidative stability, making it a superior choice for demanding formulations. It is a critical ingredient for manufacturers in the cosmetics, personal care, pharmaceutical, and food industries seeking reliable, high-performance excipients and carriers.

Application

• Cosmetic & Personal Care: Acts as a premium emollient, solvent, and carrier in sunscreens, creams, lotions, and makeup for its non-greasy, silky texture.
• Pharmaceuticals: Used as a solvent and co-solvent in topical drug delivery systems, enhancing the solubility of active pharmaceutical ingredients (APIs).
• Food & Flavor Industry: Serves as a carrier and solvent for flavors, colors, and vitamins in food-grade applications.
• Industrial Applications: Functions as a plasticizer, lubricant, and intermediate in specialty chemical synthesis.
• Animal Nutrition: Employed as a carrier for fat-soluble vitamins and nutrients in feed premixes.
