Propylene Glycol Dicaprylate

What is Propylene Glycol Dicaprylate?

Propylene Glycol Dicaprylate is a diester compound formed by reacting propylene glycol with caprylic acid, a medium-chain fatty acid often sourced from plant oils like coconut. This synthetic ingredient falls into the emollient and conditioning agent category for skincare and cosmetic products. It functions by lowering surface tension on the skin, delivering a silky, non-greasy feel that improves glide during application. In formulations such as lotions, creams, and foundations, it stabilizes viscosity to prevent separation, aids even distribution of active ingredients, and supports a lightweight sensory experience. Its low molecular weight promotes rapid penetration without leaving residue, making it suitable for daily-use products focused on comfort and usability across various skin types.
