| 4 | Skin sensitization | - | - | - | - | - | - |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | It has been found that the positive result of the body cell in vivo mutagenicity test (chromosome aberration test) which is a basis of three-ministry GHS classification could not be reliable data. Although the public comment demands "Not classified" based on the negative result of the in vitro examination and the in vivo genotoxicity test, at least reliable negative result in vivo mutagenicity test is required to classify as "Not classified". Therefore, "Category 2" is corrected to "Classification not possible". |
