Propylene Glycol Dicaprate

What is Propylene Glycol Dicaprate?

Propylene glycol dicaprate is a synthetic diester formed from propylene glycol and capric acid, a medium-chain fatty acid derived from natural sources like coconut oil. Commonly used in leave-on skincare products such as moisturizers, serums, and sunscreens, it acts as a multifunctional ingredient. In formulations, it lubricates the skin surface to promote smoothness, helps regulate product thickness for better spreadability and stability, and forms a light barrier that supports hydration retention without greasiness. Its low molecular weight allows quick absorption, making it suitable for lightweight textures. Derived through esterification, it mimics natural skin lipids, aiding in maintaining barrier integrity during daily use.
