Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A plant diterpene antioxidant from yew (Taxus) species. Used at tiny levels for antioxidant claims. Safety depends on careful sourcing because yew also contains toxic compounds.
Taxamairin A (CAS 110300-76-0) is an abietane-type diterpene isolated from Taxus species, used in cosmetics as a natural antioxidant. Taxus plants also produce cytotoxic taxane alkaloids (paclitaxel family), making source purity critical. No published CIR or SCCS opinion on taxamairin A specifically; toxicology data is very limited and derived largely from academic phytochemistry rather than cosmetic safety dossiers. At cosmetic use concentrations (typically ppm-level) with verified purity, systemic risk is minimal, but evidence level is low and consumer-facing caveats are warranted.
