An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.

About this composition

This record is anchored to a directly read public GC/MS batch report for Cinnamomum cassia oil and cross-checked against public cassia profile pages for plant part, extraction, aroma, and safety context. The public batch profile is strongly cinnamaldehyde-dominant with smaller o-methoxycinnamaldehyde, cinnamyl acetate, and coumarin fractions.
