Isoeugenol must be separately declared in the ingredient list (INCI) when its concentration in the finished product exceeds these values. Below the threshold, no separate mention is required.
Typical concentration ranges (of the oil itself, not the finished product):
Example: at 1.5% lavender oil in a leave-on cream with linalool at up to 45%, the product contains up to ~0.68% linalool — far above the 0.001% threshold, so it must be declared.
Upload your supplier PDFs and Allergen81 extracts every allergen, runs the threshold math (including pre-hapten grouping), and generates your INCI-compliant label.
Under EU Regulation 2023/1545, Isoeugenol must be listed separately in the ingredient declaration (INCI) when its concentration in the finished product exceeds 0.100% in leave-on products or 1.00% in rinse-off products.
Isoeugenol naturally occurs in: Vetiver Oil, Clove Bud Oil. Typical concentration ranges in these oils vary — always confirm with a supplier IFRA certificate or GC/MS report.
