About ILEX AQUIFOLIUM LEAF POWDER

European holly (Ilex aquifolium) leaf powder — a tannin-rich botanical used for astringent and antioxidant effects. Use leaf only, not berry.

Detailed Analysis

Ilex aquifolium leaf powder is milled from the evergreen leaves of European holly. The leaves contain tannins, saponins (ilexins), and caffeic acid derivatives, supporting astringent and antioxidant cosmetic claims. Holly berries are well known to be toxic on ingestion and are not an acceptable cosmetic feedstock; only leaves may be used. EU CosIng lists the leaf ingredient without specific restriction and no GHS hazard is assigned to purified leaf powder. Cosmetic-specific safety literature is thin, and saponin content may irritate mucosa.
