Can you provide a Certificate of Analysis (COA) for this lime oil?

Yes. A batch-specific COA ships with every order and is issued before release.

What the COA contains

  • Batch code, production date and retained-sample reference
  • Botanical name, plant part and process route
  • Appearance, colour and odour
  • Relative density and refractive index (measured values)
  • GC-MS fingerprint with the key markers
  • Heavy metals and microbiological results

A retained sample is kept for every lot, so the COA can be re-checked within the shelf life. COA, SDS and origin documents are re-issued on request, and third-party testing (SGS, Eurofins) can be arranged at the buyer's cost.
