β-Thujaplicin

Hinokitiol is a naturally-derived extract from certain evergreen trees that prevents bacterial and fungal formation in cosmetic formulations. This all-natural product has a pleasant evergreen odor and improves the shelf life of cosmetics especially after the initial opening of the product & use by consumers.
Hinokitiol has shown very strong preservative properties even in small concentrations as compared to sorbic acid and other common cosmetic preservatives.
