Caprylyl Glycol

What is Caprylyl Glycol?

Caprylyl glycol is an eight-carbon diol, a type of alcohol compound often derived from plant sources like coconut or palm kernel oil through esterification and reduction processes. In cosmetics, it serves primarily in moisturizers, serums, cleansers, and hair products. As a humectant, it draws moisture from the environment into the skin's upper layers, enhancing hydration. Its emollient properties allow it to lubricate the skin surface, reducing friction and promoting smoothness. It also acts as a skin and hair conditioning agent by forming a light film that improves manageability and shine. Additionally, it functions as a preservative booster, enhancing the efficacy of other antimicrobial agents without strong biocidal activity itself. This multifunctional nature makes it suitable for both rinse-off and leave-on formulations across various product categories.
