Limonene
Allowed
D-Limonene
The citrus-peel terpene that gives orange, lemon and grapefruit oils their smell, and a capable degreasing solvent.
- What it does
- Scent
- Our take
- Along with linalool, the name most likely to alarm someone reading an all-natural label. If a cleaner or a body wash is scented with citrus oil, limonene comes with it. Like linalool it oxidises in air into more sensitising compounds, so an old bottle of citrus-scented anything is more irritating than a fresh one. We permit it and would rather explain it than let the name do the scaring.
- Scope
- A label cannot tell you whether this was extracted from a plant or built in a lab, because the molecule is identical either way. Seeing it named is a disclosure rather than a warning: it is what an honestly labelled, essential-oil-scented product looks like, and the EU requires it to be named precisely so that the minority of people who react to it can avoid it.
