Propylene glycol dicaprylate

Propylene glycol dicaprylate (CAS 7384-98-7), also known as propylene glycol dioctanoate and 1,2-Dicaprylin, is a diester of propylene glycol and caprylic acid. It is used as a solvent, carrier, and emollient across food, pharmaceutical, and cosmetic manufacturing.

Its FEMA 4471 designation supports its use in flavoring applications. Low viscosity and good lipid solubility make it a practical vehicle for active ingredient delivery in various industrial processes.

In pharmaceutical formulations, it functions as a carrier for lipophilic actives in softgel capsules and oral lipid-based drug delivery systems. It is also utilized in topical preparations to enhance the delivery of active compounds.

Food manufacturers use it as a flavor carrier and dispersant, particularly in emulsified flavor systems. This ensures the uniform distribution of oil-soluble compounds required for consistent product quality and taste profiles.

In personal care, it acts as an emollient and spreading agent in skin creams, serums, and sunscreen formulations. It improves texture without a heavy or greasy feel, making it ideal for high-end cosmetic applications.

It also serves as a plasticizer in film coatings for tablets and functional food products. This versatility allows manufacturers to achieve specific structural properties in finished solid dosage forms and nutritional supplements.

Propylene glycol dicaprylate is supplied as a clear, low-viscosity liquid. It is available in food-grade and pharmaceutical-grade specifications, with the latter typically conforming to Ph.Eur. monographs for excipient use.

Bulk supply is standard in drums and IBC containers for industrial scale. Kosher and halal certifications are commonly available to meet the specific regulatory requirements of food and nutraceutical applications worldwide.
