Description

Propylene Glycol Caprylate is a high-purity, non-ionic surfactant and solubilizer derived from propylene glycol and caprylic acid. This versatile compound is valued for its excellent solubilizing power, low toxicity, and mild nature, making it a critical functional ingredient in advanced formulations. It is primarily sought after by manufacturers in the pharmaceutical, personal care, and food industries for its ability to enhance the solubility and bioavailability of active ingredients.

Application

• Pharmaceutical solubilizer and emulsifier for oral, topical, and injectable formulations.
• Key excipient in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS).
• Solubilizing agent for vitamins, flavors, and fragrances in food and nutritional supplements.
• Emollient and co-emulsifier in high-end skincare creams, lotions, and sunscreens.
• Carrier solvent for active ingredients in cosmetic and personal care products.
• Intermediate in the synthesis of more complex esters and specialty chemicals.
• Plasticizer and processing aid in select polymer applications.
