Consistency is controlled by releasing every lot against the same specification and comparing it to a retained reference profile. ControlsSame cultivar source and process route lot to lot.Density and refractive index held inside 0.830-0.890 (25/25 °C) / 1.450-1.490 (25 °C).GC-MS fingerprint compared with the reference profile before release.Retention sample stored for re-test within the shelf life.If your application needs a tighter tolerance, G4S can select lots from the same source or blend to a target profile. Every shipment carries a lot number linking to the COA on file.

In aromatherapy the oil is used for diffusion and for dilution into massage and bath blends, valued for its soft, uplifting lemon character. PracticeDiffusion: a few drops in a diffuser; citrus oils are used for short sessions.Massage and topical use: dilute in a carrier oil, typically 1-2%, and patch test first.Blends: citrus-floral and citrus-herb blends for a bright, clean room character.The oil is low phototoxic risk (distilled, not expressed), but standard dilution practice still applies. G4S supplies the SDS and the allergen declaration for professional use.

The oil smells a soft, rounded perfume-lemon character — gentle peel sweetness with a light floral lift and a clean, low-bitterness finish. ProfileTop: soft, fresh peel with gentle sweetness rather than a sharp acidic bite.Heart: rounded floral-fruity lemon body.Drydown: clean and short; like all citrus oils it is a top-note material.Odour is assessed by an in-house panel against the retained reference sample before release. A reference sample from the current lot can be shipped with your evaluation sample so your perfumer and our panel judge the same material.
