What are the physicochemical properties of this lavender oil?

Question

Accepted Answer

Relative density 0.875–0.895 (20°C), refractive index 1.459–1.470 (20°C), optical rotation -12.0° to -6.0° and acid value ≤1.2 — the oil fully aligns with GB/T 12653-2008 and ISO 3515 physical limits.

Each COA lists measured values per batch, tested by GB/T 11540-2008 (density), GB/T 14454.4-2008 (refractive index), GB/T 14454.5-2008 (optical rotation) and GB/T 14455.5-2008 (acid value).Send our COA to your QC lab for cross-checking. We can also prepare a third-party test report on request.
