Lemon Oil (Citrus limon) naturally contains 4 substances regulated under EU 2023/1545: Limonene (typically 55–75%); Pinene (typically 10–18%); Citral (typically 1–5%); Alpha-Terpinene (typically 0.1–0.5%). 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 (CITRUS LIMON PEEL 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 Lemon Oil usually trigger declarations.
It depends on the constituent with the highest typical level. For example, Limonene, Lemon Oil's most abundant regulated allergen (up to 75%), crosses the 0.001% leave-on threshold once the oil itself exceeds ~0.00% of the formula.
