Is this green mandarin oil 100% natural and undiluted?
Yes. TPS-RO-012 is supplied as 100% natural, undiluted cold-pressed oil — nothing is cut with carrier oil, synthetic limonene, or solvent. The physical constants and GC-MS fingerprint prove it on every batch.
Purity Commitments
| Check | What it proves |
|---|---|
| No carrier-oil dilution | Density 0.845-0.860 and RI 1.473-1.479 — a fixed-oil cut shifts both immediately |
| No synthetic limonene top-up | Gamma-terpinene stays at 16-22% and natural MNMA is present — synthetic-limonene adulteration dilutes both markers |
| No solvent residues | Extraction is physical (cold pressing); residual-solvent screen is still run per batch |
| No artificial colour | The natural green comes only from unripe-peel chlorophyll |
| GC-MS fingerprint | Full chromatogram against the reference Xiao Qing Gan profile is released on request |
- "Natural" means the oil comes only from the botanical source by physical expression — no chemically altered fractions
- "Undiluted" means the batch is 100% oil with 0% carrier or solvent; your own dilution is your formulation choice
- The CoA states density, RI, optical rotation, peroxide value, and the full GC-MS component table so you can verify purity on arrival
- For perfumery, the IFRA 51st Certificate of Conformity is issued for the natural oil as such (with the 2% category-4 restriction on furocoumarin-bearing citrus)
