What it is
This extract is obtained from the peel of the bitter orange, Citrus aurantium amara, and is rich in aromatic and water-soluble citrus constituents. It is used in cosmetics for its citrus scent as a fragrance or scent-masking ingredient and as a skin-conditioning botanical. In sunscreen formulas it serves a supportive aromatic role rather than a UV-protective one.
Safety & warnings
Citrus peel materials contain limonene and related terpenes that are recognized fragrance allergens and may sensitize susceptible skin. Citrus peel can also be a source of furocoumarins that increase skin sensitivity to UV light, so its use in leave-on, sun-exposed products warrants some caution.
