THE SCIENCE BEHIND THE SCENT

Inside the oil

6 constituents

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

About this composition

Eden Botanicals' live Cognac EO page identifies this oil as green cognac distilled from wine lees left after fermentation and aging of cognac. Public supplier SDS and pyrolysis reference material agree that green cognac is dominated by fatty-acid ethyl esters, especially ethyl decanoate / caprylate-caproate-laurate-palmitate/myristate fractions, which explains its fruity, winey, diffusive, and tenacious profile.

A TRADITION OF BOTANICAL CURIOSITY

Traditional & reported uses

These uses reflect the profile's reported traditions and literature. They are not established treatment recommendations.

used in perfumery for its fruity, boozy, wine-lees character in fine fragrance
traditionally associated with warm, sophisticated, evening-fragrance atmospheres
used as a distinctive top-to-heart note in gourmand and chypre-style compositions
shares the traditional convivial, celebratory reputation of other wine and spirit-derived aromatics
used sparingly in blends for its powerful, ester-rich fruity-fermented facet

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 from public safety language stating no specific safety information or IFRA restriction was found for green cognac, not a directly published numeric dermal cap.
Odor intensity 85 is a normalization from Eden Botanicals' qualitative description of a powerful, intensely diffusive, outstandingly tenacious aroma rather than a published 0-100 measurement.
Public open sources reviewed here provide partial component disclosure for green cognac rather than a full modern GC-MS fingerprint, so minor constituents remain outside this first-pass record.
