Based on the mouse 4-hour LC50 value of 178 ppm (PATTY, 5th (2001)), the substance was classified as Category 2. Although the rat LC50 value of > 235 ppm/4hrs was reported (PATTY, 5th (2001)), the category can not be specified from this data. The test concentration (178 ppm) was lower than 90% of the saturated vapor pressure concentration (543 ppm), the criterion values for gas were adopted. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available. |
| 2 | Skin corrosion/irritation | Not classified | - | - | - | - | In the rabbit test, 4-hour application of 0.5 mL of test substance to skin caused very slight erythema in 1 of 3 animals and slight erythema and slight edema were noted in second animals, and very slight to slight erythema in the third rabbit (HSDB (2006)). These symptoms were all reversible within 8 days, and it was concluded that this substance was not irritated. Therefore, the substance was classified as "Not classified". |
| 3 | Serious eye damage/eye irritation | Not classified | - | - | - | - | The substance was classified as "Not classified" based on the result of rabbit eye test that instillation of the test substance caused slight irritation and irritation intensity was 1 in 1 - 10 grade (PATTY, 5th (2001)). |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | No data available. |

| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available |
| 10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available. |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |

|
Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Classified into Category 1 from its 48h-EC50 = 0.15 mg/L for crustacea (Daphnia magna) (HSDB, 2010). |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 1 |
|
Warning | H410: Very toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
