A humectant, solvent, and preservative booster.
Caprylyl glycol is used in skincare for a number of purposes. It’s a great humectant, meaning it draws water towards itself and helps hydrate and plump the skin. It’s a solvent, so it helps ingredients stay dissolved in a formula. And it helps boost the efficacy of certain preservatives, ensuring a long shelf life.
