Citrus Aurantium Dulcis Peel Oil
Citrus Aurantium Dulcis Peel Oil, also known as Sweet Orange Peel Oil, is the volatile essential oil obtained by expression from the peel of Citrus sinensis (sweet orange). Its main component is limonene, which comprises 83–97% of the oil and is responsible for its characteristic citrus scent. It also contains furanocoumarins, compounds associated with mild phototoxicity. It is listed under CAS # 8008-57-9.
Primarily used as a perfuming and masking agent in cosmetic formulations due to its pleasant citrus scent. It also has minor skin conditioning properties as listed in official CosIng functions. Evidence for meaningful standalone skin benefits beyond fragrance is not strongly supported by the source.
Contains limonene, a frequent skin sensitizer. Also contains furanocoumarins, making it mildly phototoxic — caution is advised when used in daytime products or leave-on formulations with sun exposure. Orange peel contains less furanocoumarin than bergamot or lime, but the risk is still present.
