Scientific Taxonomy & Fragrance Chemistry
Olfactory Chemistry & Evaluation Methodology
Every formulation in the The Perfume Encyclopedia archive is cataloged using molecular volatility dynamics, GC-MS compound estimates, and strict adherence to IFRA / ISO 9235 conventions.
1. GC-MS Gas Chromatography Mapping
Fine fragrances are complex molecular orchestrations. Our archive indexes the primary synthetic isolates and captive molecules that define modern niche sillage and tenacity:
Iso E Super • C16H26O
Velvety cedarwood-amber radiance with expansive skin aura.
Ambroxan • C16H28O
Crystalline dry ambergris note with immense projection and tenacity.
2. Olfactory Pyramid Volatility Dynamics
Our olfactory pyramid model categorizes compounds by thermodynamic evaporation curves:
- Top Notes (0 - 30 Minutes): High vapor pressure volatile citrus, aldehydes, and aromatic terpenes (Bergamot, Pink Pepper).
- Heart Notes (30 Mins - 4 Hours): The core identity consisting of florals, warm spices, and herbal lactones (Rose, Iris, Lavender).
- Base Notes (4 - 24+ Hours): High molecular weight resins, fixative musks, vanillin, and precious woods (Oud, Patchouli, Amber).
3. IFRA & ISO 9235 Standards Protocol
Catalog entries reference the IFRA 51st Amendment standards and ISO 9235 definitions for natural aromatic raw materials, tracking restricted compounds (e.g. Oakmoss atranol limits, Lilial transitions) across historic formulation batches.
