What are the physicochemical properties of this litsea cubeba oil?
This litsea cubeba oil (TPS-RO-009) has the classic physicochemical profile of a citral-rich berry distillate: a light mobile liquid with a density slightly lighter than water and a refractive index near 1.48. The reference values below are measured at 20°C unless stated, in line with GB/T 11424-2008, GB 1886.35-2015, ISO 3214:2000 and FCC 12.
Physicochemical Properties
| Property | Reference value |
|---|---|
| Relative density | 0.860-0.890 (20°C); GB 1886.35: 0.880-0.905 (25°C/25°C) |
| Refractive index | 1.480-1.490 (20°C) |
| Optical rotation | +1° to +12° (20°C, GB 1886.35) |
| Solubility | 1 mL dissolves in 3 mL of 90% ethanol, clear (GB 1886.35) |
| Flash point | 54.4-71°C (open-cup 54.4°C; closed-cup ≥71°C) — Class 3 flammable liquid |
| Boiling range | Citral fraction distils ~225-229°C (atmospheric) |
| Shelf life | 36 months in sealed, cool, dark storage |
- The density window 0.860-0.890 at 20°C is the customer-facing spec; slightly different windows apply per standard (e.g. GB 1886.35 uses 0.880-0.905 at 25°C/25°C)
- The low flash point matters for shipping: the oil is classified UN 1993, Class 3 (flammable liquid), PG III
- Full COA lists all measured values batch by batch, including the GC citral content
