The release window below is the specification G4S tests against; every COA reports the measured value for that batch.

Density and refractive index are run per lot at the stated temperature; lots outside the window are not released.

For the US, citrus peel oils are used as flavouring substances under the FEMA GRAS framework and referenced in FDA 21 CFR 182.20 for the essential-oil category. Documentation suppliedCOA with identity, physical constants and contamination results.SDS in US format (OSHA HazCom).Allergen declaration and food-use statement.Botanical, cultivar and process declaration for label review.The finished-product producer confirms its own product category, label and market eligibility — G4S supplies the material data to make that review straightforward.

G4S uses Steam distillation for this grade. The peel is steam-distilled at low pressure, which gives a clean, soft profile without solvent contact and without the heavy residue of an expressed oil. Why this routeNo solvent is used, so there is no solvent-residue carry-over to declare.Distillation keeps the profile soft and clean, which suits fine-fragrance work.The natural marker ratios of the peel are preserved rather than rebuilt from fractions.The process route, batch yield and key operating parameters are recorded on the batch file, and the COA states which route was used.
