I. Evaporation Kinetics: 100% Pure Oil Extrait vs. Alcohol Sprays
Commercial designer perfumes dilute fragrance oils with 80% to 90% denatured ethanol. While ethanol creates an initial volatile burst, it evaporates completely within 45 to 90 minutes, taking volatile top notes with it. Pure concentrated perfume oils bind directly to epidermal lipids, releasing aromatic molecules gradually at skin temperature (33°C to 37°C).
| Format | Oil Concentration | Alcohol Content | Active Sillage Window | Residual Longevity |
|---|---|---|---|---|
| Raees Pure Extrait Oil | 100% Neat Concentrate | 0% (Alcohol-Free) | 6 to 10 Hours | 18 to 24+ Hours |
| Commercial Extrait de Parfum | 20% – 30% | 70% – 80% | 4 to 6 Hours | 8 to 12 Hours |
| Eau de Parfum (EDP) | 15% – 20% | 80% – 85% | 2 to 4 Hours | 6 to 8 Hours |
| Eau de Toilette (EDT) | 5% – 12% | 88% – 95% | 1 to 2 Hours | 3 to 5 Hours |
II. Candle & Diffuser Manufacturing Specifications
For commercial candle studios and home scenting manufacturers in the US and Europe, oil stability and flashpoint determine safety and hot throw efficiency:
| Fragrance Family | Average Flashpoint | Specific Gravity @ 25°C | Recommended Candle Load | Reed Diffuser Base Load |
|---|---|---|---|---|
| Oriental Amber & Resins | > 98°C | 0.985 – 1.020 | 8% – 10% | 15% – 20% |
| Vintage Dehn Al Oud Accords | > 100°C | 0.992 – 1.035 | 7% – 9% | 12% – 18% |
| Botanical Floral & Rose | 88°C – 94°C | 0.945 – 0.980 | 6% – 8% | 15% – 22% |
III. Agarwood Distillation Yield Empirical Data
Pure wild Aquilaria agallocha (Assam) and Aquilaria crassna (Trat) require decades of microbial fungal induction before resin saturation occurs. Our distillation records indicate:
- Raw Wood Requirement: Approximately 20kg to 25kg of resinous wild heartwood yields exactly one tola (11.66g / ~12ml) of first-press Dehn Al Oud.
- Distillation Duration: 14 to 21 continuous days of hydro-distillation in copper alembics at strictly regulated boiling points.
- Curing Cycle: Degassed in unsealed glass vessels under controlled sunlight for 90 days to release water molecules before airtight decanting.
IV. Sources & Methods
- Evaporation curves: In-house 24-hour transdermal release panels at 33-37C, timed against commercial EDP/EDT reference sprays of equivalent concentration.
- Flashpoint and density: Standard closed-cup flashpoint determination and 25C specific-gravity measurements per fragrance family, taken on production lots.
- Agarwood yield records: Cumulative hydro-distillation logs from the Deira atelier (Aquilaria agallocha, Assam, and Aquilaria crassna, Trat), including raw-wood input, alembic duration and curing cycle.
- Safety reference: Dermal limits follow IFRA (International Fragrance Association) maximum usage standards; commercial lots ship with COA and MSDS documentation.
