Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | - | Since its rat LD50 is > 5000 mg/kg (DFGOT vol. 3 (1992)), the substance was classified into the "Not classified" category. |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | - | No data available. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | - | Solid (GHS definition) |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | - | No data available. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | - | Insufficient data available. |
2 | Skin corrosion/irritation | Not classified | - | - | - | - | Since rabbit tests found that the substance causes no irritation (DFGOT vol. 3 (1992)), it was classified into the "Not classified" category. |
3 | Serious eye damage/eye irritation | Not classified | - | - | - | - | Since rabbit tests found that the substance causes no irritation (DFGOT vol. 3 (1992)), it was classified into the "Not classified" category. |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
4 | Skin sensitization | Classification not possible | - | - | - | - | No data available. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Classification is not possible due to lack of in vivo test data. Regarding in vitro tests, Ames tests yielded negative results (IARC 36 (1985)). |
6 | Carcinogenicity | Not classified | - | - | - | - | Since the substance is placed in Group 3 in the IARC's classification, it was classified into the "Not classified" category. Tests have been conducted in which mice or rats received long-term subcutaneous administration or dermal administration-- no exposure-related tumorigenesis was observed in either test (IARC 36 (1985)). |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available. |
8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | No data available. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | In 4-months mixed diet administration tests using rats, decreased hemoglobin and erythrocytes, increased reticulocytes, and increased methemoglobin formation were observed (HSDB (2002)). However, degrees of these changes in blood indices were not provided; in addition, detailed explanations regarding doses used were not provided other than doses used being indicated as "2% or 5%, and LD50 or LD33." As such, due to insufficient information available, classification is not possible. |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available. |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Classification not possible | - | - | - | - | No data available. |
11 | Hazardous to the aquatic environment (Long-term) | Classification not possible | - | - | - | - | No data available. |
