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

ParameterSpecification (20°C)
AppearanceClear 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)
Solubility1:2 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
