Cedarwood Atlas Oil (Cedrus atlantica) naturally contains 1 substances regulated under EU 2023/1545: Limonene (typically 0.1–1%). Exact values vary by harvest and producer — confirm with a GC/MS report or IFRA certificate.
The oil itself is declared under its INCI name (CEDRUS ATLANTICA BARK OIL). Additionally, each regulated constituent that exceeds 0.100% (leave-on) or 1.00% (rinse-off) of the finished product must be listed separately — e.g. "linalool". Because many constituents run high, even small doses of Cedarwood Atlas Oil usually trigger declarations.
It depends on the constituent with the highest typical level. For example, Limonene, Cedarwood Atlas Oil's most abundant regulated allergen (up to 1%), crosses the 0.001% leave-on threshold once the oil itself exceeds ~0.10% of the formula.
