Propylene glycol dicaprylate

Propylene glycol dicaprylate (CAS 7384-98-7) is a diester formed from propylene glycol and caprylic acid. It is commercially available under trade names including Edenol 302, Sefsol 228, Liponate PC, and P 72. It carries no E-code designation and is classified within the oils, fats, and waxes category.

In pharmaceutical and nutraceutical formulations, it functions as a lipophilic carrier that solubilises active compounds with poor aqueous solubility, improving bioavailability in softgel and liquid-fill capsule systems. In personal care, it acts as an emollient and co-emulsifier, reducing interfacial tension between oil and water phases to stabilise creams and serums.

Propylene glycol dicaprylate is supplied in cosmetic, pharmaceutical, and food-grade variants, with compliance referenced against REACH registration requirements and relevant pharmacopoeial standards. It is typically available in drum and IBC packaging. Buyers should confirm grade-specific documentation, including safety data sheets and certificates of analysis, prior to procurement.
