What are the physicochemical properties and specifications of this sweet orange oil?
Each batch is tested against the international benchmark ISO 3140:2019 and Chinese standard GB/T 11424-2008, which define the physical limits for authentic cold-pressed sweet orange oil.
Physicochemical Specifications
| Parameter | Specification (20°C) |
|---|---|
| Appearance | Clear liquid, yellow to orange |
| Relative density (d20/20) | 0.842-0.850 |
| Refractive index (nD20) | 1.470-1.476 |
| Optical rotation | +94° to +99° |
| Aldehyde content (as decanal) | 0.5-2.8% |
| Evaporation residue | ≤6.0% (GB/T 11424-2008) |
| Solubility | 1:2 soluble in 90% ethanol (clear at 20°C) |
- Relative density and refractive index are the primary identity checks — values outside the range indicate dilution, adulteration or contamination
- Optical rotation is strongly positive because of the high d-limonene content
- Flash point ≈ 47-53°C — treat as a combustible liquid in storage and transport
- Full GC-MS fingerprint, physicochemical data and allergen declarations are provided on the batch COA
- Specifications are consistent with ISO 3140:2019, GB/T 11424-2008 and FCC (Food Chemicals Codex) for orange oil
