What are the full physicochemical properties of this valerian root oil?
Valerian root oil has a defined physicochemical profile covering density, refractive index, optical rotation, miscibility, and acid value — set per our spec and T/CAFFCI 70-2023.
Physicochemical Properties
| Parameter | Value (our spec) | Standard range (T/CAFFCI 70-2023) |
|---|---|---|
| Relative density (20°C) | 0.910–0.995 | 0.845–1.033 (20°C/20°C) |
| Refractive index (20°C) | 1.470–1.510 | 1.331–1.627 |
| Optical rotation (20°C) | — | −38° to −8° |
| Miscibility (20°C) | Soluble in ethanol & fixed oils | 1 vol in 2 vol 85% ethanol, clear |
| Acid value (mg KOH/g) | ≤ 13 | ≤ 13 |
| Appearance | Clear to pale yellow-green to dark brown-green liquid | Transparent to semi-transparent |
| Shelf life | 36 months | Per GB 7718 / industry practice |
- Our density/RI ranges fall within the standard's wider bands — a reasonable tightening reflecting premium-grade quality control
- Test methods: density GB/T 11540, refractive index GB/T 14454.4, optical rotation GB/T 14454.5, miscibility GB/T 14455.3, acid value GB/T 14455.5
- Values are measured with a KEM DA-840 digital density meter and KEM RA-600 automatic refractometer, reported on the batch COA
- The oil is heavier than water (sinks in aqueous phase) — an important handling fact for distillation and separation lines
