- 4%
- Phototoxicity
- Phototoxic — use caution
- Maximum for sun-exposed skin
- 4%
- Oxidation risk
- high
A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.
Expressed grapefruit oil is phototoxic; Tisserand Institute's current public dilution chart states grapefruit oil can be used at up to 4% to avoid phototoxicity. Bergapten-free or low-furanocoumarin grapefruit oils are considered non-phototoxic.
Contraindications & cautions
- moderatePhototoxic in leave-on dermal use when expressed; bergapten-free/low-furocoumarin variants differ.

What we're still learning · 2 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- No public source reviewed in this pass published a native 0-100 odor-intensity value; the archive's 60 is a normalization of The Good Scents Company's categorical 'medium' odor-strength label.
- Public grapefruit references reviewed in this pass did not provide a directly stated volatility-rate metric.
