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
Hermitage Oils presents this Signature Gold material as a top-tier green cognac batch with especially bright boozy-fruity lift and fewer fatty or acrid aspects than average French lots. The live product page does not expose batch GC data, so the quantitative profile below uses open green-cognac composition disclosures from current supplier SDS and public reference material for the same natural complex substance type.

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
For aromatherapy and wellness use only — not medical advice. Effect statements are traditional/reported associations, not treatment claims. The Synergy Rating scores blend craft, harmony and safety, not medical efficacy. Read the safety framework.
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 IFRA restriction was found for green cognac, not a directly published numeric dermal cap for this Signature Gold batch.
- Odor intensity 90 is a normalization from Hermitage Oils' qualitative description of bombastic power, bright boozy-fruity lift, and top-tier tenacity rather than a published 0-100 measurement.
- No public batch-specific GC profile was exposed on the live Signature Gold product page in this pass, so the quantified constituent values are inherited from open green-cognac reference disclosures rather than from this exact lot.
