About ZANTHOXYLUM ALATUM FRUIT OIL
A citrusy-spicy essential oil from a Himalayan prickly ash tree, used in traditional medicine and perfumery with limited modern cosmetic safety data.
Detailed Analysis
Zanthoxylum alatum fruit oil is a volatile oil expressed from the fruits of a Rutaceae species native to Himalayan regions, yielding an oil valued in traditional medicine and perfumery for its citrusy-camphoraceous notes. Key constituents include limonene, linalool, and sanshool derivatives. Under EU cosmetic regulation EC 1223/2009, Z. alatum is not listed in Annex II (banned) or Annex III (restricted) and has no specific CosIng authorization, placing it in the 'no specific regulation' category. Sanshool compounds have been associated with mild skin irritation in some studies, and as with most essential oils, standardization varies by supplier, making concentration thresholds important.
