It is a humectant, meaning it attracts and binds water to skin. Because of the structure and surface activity of caprylyl glycol, it can also have an effect on the viscosity and stability of emulsion products. It has limited solubility in water and is commonly used with other water solubilizing agents. Studies have also found that caprylyl glycol has some antibacterial properties, and that it can help boost the preservative blend used in some leave-on skin care products. In its raw form, caprylyl glycol is a waxy solid. The Cosmetic Ingredient Review panel has found caprylyl glycol safe as used in cosmetics in amounts between 0.00003%–5%. Toxicologic testing did not reveal caprylyl glycol to be a skin or eye irritant in amounts commonly used in cosmetics. Related ingredients: Propylene Glycol
