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 |
|---|---|
| Benzaldehyde | 0.01 % |
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

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.
