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 cineole chemotype record is anchored to a directly readable Tunisia batch GC sheet that publishes both measured percentages and the supplier's rosemary-cineole normative ranges. The batch is strongly 1,8-cineole dominant, with alpha-pinene, camphor, beta-pinene, and camphene as the main supporting markers and verbenone below the detection threshold used on the sheet.

What we're still learning · 2 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- max_dermal_pct 1 is taken from the directly read legacy IFRA 48 certificate's leave-on Category 5 maximum for this Tunisia rosemary cineole ingredient rather than from a newer IFRA 51 category table for the same exact batch.
- Odor intensity 65 is an archive normalization from public qualitative wording such as fresh, herbaceous, camphoraceous, invigorating, and stimulating rather than a native published 0-100 measurement.
