About

A warming, aromatic bark powder from Ceylon cinnamon — antioxidant and antimicrobial, but cinnamaldehyde content makes it a sensitizer that needs careful dilution.

Cinnamomum zeylanicum (Ceylon cinnamon) bark powder contains cinnamaldehyde as the major component (50-60%), along with eugenol, linalool, and other volatile compounds. Unlike C. cassia, Ceylon cinnamon has negligible coumarin content. The bark demonstrates antioxidant activity from its polyphenolic fraction and broad-spectrum antimicrobial properties. Cinnamaldehyde causes dose-dependent skin sensitization; cosmetic regulations in the EU require allergen declaration. Appropriate dilution (typically <0.1%) keeps sensitization risk manageable.
