What are the physicochemical specifications of this orris absolute?
This orris absolute meets a fully documented physicochemical profile: relative density 0.920–1.000 (20°C), refractive index 1.480–1.530 (20°C), waxy semi-solid at room temperature, shelf life 36 months — aligned with the FCC 1996 quality indicators for orris concrete (irone content 9–20%, melting range 38–50°C, heavy metals negative).
Physicochemical Specifications
| Parameter | Value |
|---|---|
| Relative density (20°C) | 0.920–1.000 |
| Refractive index (20°C) | 1.480–1.530 |
| Appearance | Viscous liquid to semi-solid paste (waxy at RT) |
| Color | Pale yellow to cream to brownish |
| Shelf life | 36 months |
| Melting behavior | 38–50°C (FCC reference for orris concrete) |
- Irone content follows the FCC range of 9–20% and is verified by GC per ISO 18054:2004
- Acid and ester values are reported per batch to confirm the natural fatty-acid profile
- The density and refractive ranges are slightly wider than the legacy Soviet TY standard, reflecting the modern combined ISO/FCC acceptance window
