CINNAMOMUM CULILAWAN LEAF EXTRACT.

Questionable CAS 91771-48-1 / PERFUMING

A botanical extract derived from the leaves of the Culilawan cinnamon tree, primarily utilized in skincare for its aromatic masking properties. While it contains bioactive compounds like eugenol that offer antioxidant potential, it is frequently categorized as a fragrance component rather than a primary active.

Antioxidant Fragrance agent Masking agent Anti-inflammatory

Science

The extract operates through its high eugenol content to scavenge free radicals and mitigate oxidative stress. It is theorized to modulate inflammatory pathways—specifically inhibiting NF-κB signaling and reducing levels of pro-inflammatory cytokines such as IL-6 and TNF-α—while also providing secondary antimicrobial benefits.
