Dipropylene Glycol Caprylate

What is Dipropylene Glycol Caprylate?

Dipropylene glycol caprylate is a synthetic ester produced by reacting dipropylene glycol—a colorless, odorless polyether alcohol derived from propylene oxide—with caprylic acid, a medium-chain fatty acid typically obtained from coconut or palm kernel oils. Commonly used in skincare products like lotions, serums, and creams, it functions as an emollient by creating a protective barrier on the skin that mimics natural lipids, promoting smoothness and reducing the appearance of roughness. Its low molecular weight and non-greasy profile allow it to improve product slip and blendability, making formulations feel light and fast-absorbing while aiding even distribution of active ingredients. This ingredient also contributes to skin conditioning by helping preserve the skin's flexibility and hydration balance without heaviness.
