About
Chamazulene is a cosmetic ingredient used in product formulations. Note: classified as harmful to aquatic environments. Exercise caution due to limited available safety data.
Chamazulene (also called guaiazulene) is a sesquiterpene azulene derived from the essential oils of chamomile (Matricaria chamomilla) and blue tansy (Tanacetum annuum). It is used in cosmetics for its potent anti-inflammatory, antioxidant, and skin-soothing properties. Chamazulene is not listed on any EU restriction Annexes; it is considered safe at concentrations up to 0.1% in cosmetic formulations. SCCS notes high cosmetic acceptance and low systemic toxicity. The ingredient is permitted in all cosmetic product types including leave-on and is a popular natural-derived active for sensitive skin formulations.
