Safety
Safety Profile
Thuja Occidentalis Bark Extract is classified as 'Regulated' in cosmetic ingredients in Europe and the United Kingdom, indicating a low penalty in all categories by INCI Beauty standards. The presence of thujone, a chemical found in the plant Thuja occidentalis, necessitates precise extraction methods to minimize its content in the final extract. For topical preparations, specific solvent types (ethanol and/or water), extract ratios, and product concentrations are advised to manage potential toxicity.
