About ZANTHOXYLUM PIPERITUM SEED OIL

A spicy, aromatic volatile oil steam-distilled from the seeds of Japanese pepper (sansho), used primarily as a fragrance and flavouring agent in cosmetics. Like many essential oils, it carries a moderate sensitization risk.

Detailed Analysis

Zanthoxylum Piperitum Seed Oil is a volatile essential oil whose principal constituents include limonene, linalool, and other terpenes responsible for its characteristic citrus-pepper aroma. Under EU Cosmetics Regulation 1223/2009 it is not restricted per se, but several of its likely constituents (limonene, linalool) are classified as EU Annex III fragrance allergens requiring declaration above 0.001% (leave-on) or 0.01% (rinse-off). No prohibitions apply, but sensitization potential warrants patch testing and low use levels.
