About
A terpene oxide found naturally in essential oils, it is used as a fragrance ingredient with a fresh, citrusy-green scent and a clean safety profile in the concentrations typically used in cosmetic products.
Nerol oxide is a monoterpene oxide derived from nerol (a component of many essential oils including rose, palmarosa, and geranium). It functions as a fragrance ingredient contributing fresh, citrus-green, tea-like notes. It is listed in the IFRA Standards and the EU cosmetic fragrance database. No GHS hazard statements are listed in the source data. While the terpene oxide structure is not entirely without concern (oxidation products of terpene alcohols can be sensitising), nerol oxide itself has a good safety record in cosmetic use at normal dilution. It should be declared as a fragrance allergen in the INCI list when above threshold.
Skin benefits
- Provides fresh, citrus-green fragrance notes
- Natural terpene origin — appealing for natural/green cosmetic positioning
Known concerns
- Terpene oxide: theoretical oxidation product sensitisation concern at high concentrations
- Fragrance allergen — declarable in INCI at threshold concentrations
- IFRA guidelines apply to maximum use concentration
