Label snippet

Append after your INCI list (these names are required even though they originate from your essential oils — and even if you label as "fragrance-free").

Linalool, Limonene, Geraniol.

Allergen percentages are typical mid-range values from GC-MS literature — always verify against your supplier's COA before finalizing a label. The EU expanded the list to ~80 substances under Reg. 2023/1545 with a transition period through 2028; this tool covers the classic 26.
