What Is Tropolone?
Tropolone is an organic compound that can be derived from plants. It does have some antioxidant properties but is of most interest to cosmetic chemists as a preservative. Studies have shown tropolone has antimicrobial abilities, specifically the ability to combat bacterial and fungal growth. In its raw form, tropolone is a pale-yellow solid. Tropolone is usually combined with more broad-spectrum preservatives such as phenoxyethanol, where the blend is used in amounts up to 1%.
