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.

| Restriction Type | Specification |
| Critical Effect | Dermal Sensitization |
| Specification | Oxidation products of Linalool, especially hydroperoxides, have been demonstrated to be potent sensitizers. d-, l- and dl-Linalool and natural products containing substantial amounts of it, should only be used when the level of (hydro)peroxides is kept to the lowest practical level, for instance by adding antioxidants at the time of production. The addition of 0.1% BHT or α-Tocopherol for example |
