Description

Propylene Glycol Dicaprylate/Dicaprate is a high-purity, synthetic diester derived from propylene glycol and a blend of caprylic (C8) and capric (C10) 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 sensitive formulations. It serves as a critical functional ingredient for manufacturers in the personal care, pharmaceutical, and food industries seeking reliable, compliant, and high-performance raw materials.

Application

• Cosmetics & Personal Care: Acts as a premium emollient, solvent for active ingredients, and carrier oil in sunscreens, creams, lotions, and makeup for a non-greasy, silky skin feel.
• Pharmaceuticals: Used as a solubilizer and carrier in topical drug delivery systems, ointments, and transdermal patches.
• Food Industry: Functions as a carrier for flavors, colors, and fat-soluble vitamins, as well as a lubricant and release agent in food processing.
• Industrial Applications: Serves as a plasticizer, lubricant, and solvent in specialty chemical synthesis and industrial formulations.
• Animal Nutrition: Employed as an energy-dense carrier for vitamins and supplements in feed premixes.
