Citrus Aurantifolia (Lime) Peel Oil

CIT

5/10

Concern level

Moderate concern

A volatile citrus peel essential oil used primarily as a fragrance ingredient and sensory modifier. It is composed largely of terpene-rich citrus volatiles (not a single discrete molecule), so it has no meaningful molecular weight or pH of its own. Citrus peel oils are included in CIR safety reviews as cosmetic fragrance ingredients, but lime peel oil can be irritating and, when expressed/cold-pressed, may be phototoxic because of naturally occurring furocoumarins.
