Description

Propylene Glycol Caprylate is a high-purity, non-ionic surfactant and emollient derived from propylene glycol and caprylic acid. This versatile ester is valued for its excellent solubilizing properties, skin feel, and stability in a wide range of formulations. It serves as a key functional ingredient for manufacturers in the personal care, pharmaceutical, and food industries seeking effective and compliant ingredients.

Application

• Cosmetics & Personal Care: Acts as a premium emollient, solubilizer, and carrier for fragrances and active ingredients in creams, lotions, sunscreens, and deodorants.
• Pharmaceuticals: Used as a solubilizing agent and penetration enhancer in topical ointments, gels, and transdermal drug delivery systems.
• Food Industry: Functions as an emulsifier, stabilizer, and carrier for flavors, colors, and fat-soluble vitamins in various food products.
• Industrial Applications: Employed as a lubricant, plasticizer, and intermediate in specialty chemical synthesis and industrial formulations.
• Animal Nutrition: Serves as an energy source and carrier for fat-soluble nutrients in feed premixes and supplements.
