Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | - | Its rat LD50 of 2900 mg/kg bw (DFGOT vol. 9 (1998)) falls under the "Not classified" category using the JIS classification criteria (Category 5 in the United Nations classification). |
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 | - | - | - | - | No data available. |
2 | Skin corrosion/irritation | Category 2 | Warning | H315: Causes skin irritation |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P332+P313: If skin irritation occurs: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment (see ... on this label). P362: Take off contaminated clothing and wash before reuse. |
The substance is reported to be a severe irritant (DFGOT vol. 9 (1998)). It is unknown if irritation is reversible and is rated as R38 by the EU. | |
3 | Serious eye damage/eye irritation | Category 1 | Danger | H318: Causes serious eye damage |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. |
The classification is based on the description that the substance caused corrosion in rabbit tests (DFGOT vol. 9). | |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
4 | Skin sensitization | Not classified | - | - | - | - | The classification is based on the description that guinea pig Buehler tests gave negative results (DFGOT vol. 9 (1998)). |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Negative results are reported in Ames tests (DFGOT vol. 9 (1998)), but in vivo test results are not available. |
6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available. |
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 an 8-week mixed diet administration test using rats, exhaustion and focal skin lesion were noted at the dose of 1355 mg/kg/day (DFGOT vol. 9 (1998)). In a 90-day oral administration test using rats, bleeding from the mouth and nose, and decrease in hemoglobin and hematocrit values were noted at 1100 mg/kg/day (DFGOT vol. 9 (1998)). Similarly, in a 4-week feeding test using dogs, decrease in hemoglobin, hematocrit, and erythrocyte values were detected in female dogs at 122 mg/kg/day (DFGOT vol. 9 (1998)). In the first two studies, administration doses were above Category 2 guidance values, and in the third study, only one dog was tested. As such, classification is not possible due to insufficient 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 | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Category 3 | - | - | H402: Harmful to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
Since its 24-hour EC50 = 65 mg/L for crustaceans (Daphnia magna) (IUCLID, 2000), the substance was classified into Category 3. |
11 | Hazardous to the aquatic environment (Long-term) | Category 3 | - | - | H412: Harmful to aquatic life with long lasting effects |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
Since its classification for acute toxicity is Category 3, and it is not rapidly degradable (OECD 301D-compliant, 28-day degradability: approx. 40% (IUCLID, 2000)), the substance was classified into Category 3. |
