Both tenacity figures are blotter life. The two labs use different evaluation protocols, so the numbers are not directly comparable — read them as two independent readings, not as a contradiction.

Regulatory status
Restricted components
| Component | Share |
|---|---|
| Linalool | 0.01 % |
| D-Limonene | 0.001 % |
IFRA regulated substances declared for this material. For naturals — which are mixtures of many molecules — the interactive index derives the effective maximum concentration per category from them. On single molecules these shares are purity traces from the supplier specification; they are far too small to limit use and are therefore not counted.
EU allergen declaration
| Substance | Share |
|---|---|
| Linalool | 0.01 % |
| Limonene | 0.001 % |
Substances that must be named in the ingredient list under Annex III of Regulation (EC) 1223/2009, as amended by Regulation (EU) 2023/1545. Where a range was given, the upper bound is shown.
