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.

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.
