Caprylyl glycol

Caprylyl Glycol is a multifunctional cosmetic ingredient widely used in skincare, hair care, and personal care formulations. It is a colorless to slightly yellow, viscous liquid with excellent compatibility in both water-based and oil-based systems. Caprylyl Glycol is valued for its dual functionality as a skin-conditioning humectant and a preservative booster, making it an important component in modern cosmetic formulations.

Derived from caprylic (C8) fatty sources, Caprylyl Glycol helps attract and retain moisture on the skin, improving hydration and softness. At the same time, it exhibits antimicrobial properties, particularly against bacteria and fungi, which enhances the effectiveness of preservative systems and supports product stability.
