Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Not classified | - | - | - | - | It was classified into Not classified from 48 hours EC50=200mg/L of the crustacea (Daphnia magna) (SIDS (2004) and others.). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Since it was not water-insolubility (the water-solubility =5320mg/L (PHYSPROP Database, 2005)), and acute toxicity was low, it was classified into Not classified. |
