THE SCIENCE BEHIND THE SCENT
Inside the oil
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 the EMA assessment report for Roman chamomile flower oil, which describes an ester-rich profile dominated by angelates, tiglates, and isobutyrates. Open public aromatherapy references were used only for non-native odor-strength normalization and unrestricted-safety handling where no public source published a numeric leave-on maximum.

What we're still learning · 3 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- max_dermal_pct 100 is an archive normalization of unrestricted public safety guidance rather than a source-native numeric leave-on maximum.
- Odor intensity 70 is an archive normalization of AromaWeb's qualitative strength band `Medium - Strong`; no source-native 0-100 scale was publicly available in this pass.
- No public source reviewed in this pass provided verified volatility-rate or tenacity-hour values.
