What it is
Citrus Nobilis Peel Oil is a volatile essential oil obtained from the peel of the mandarin orange, dominated by limonene with smaller amounts of other terpenes. It provides a sweet citrus scent and is used in very small amounts to fragrance or mask the base odor of a formula. It is found in some Korean sunscreens for a fresh aroma rather than for any protective function.
Safety & warnings
As a citrus essential oil it contains limonene and related terpenes that are recognized fragrance allergens and can oxidize over time to become more sensitizing; it may cause irritation or contact allergy in sensitive individuals. Cold-pressed citrus peel oils can also be phototoxic, so fragrance suppliers typically limit furocoumarin content for leave-on products.
Origin & sourcing
Natural; cold-pressed from the peel of mandarin oranges (Citrus nobilis).
