---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 5 | - | Warning | H303: May be harmful if swallowed | P312: Call a POISON CENTER or doctor/physician if you feel unwell. | SPECIES: Rat ENDPOINT: LD50 VALUE: 2500 mg/kg REFERENCE SOURCE: IUCLID (2000) |
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. |
There was description that skin irritation was not admitted by the test using the rabbit (IUCLID (2000)). It was set to category 2 since there was description which suggests a potential of stimulating the human skin seriously (HSFS (2000)). | |
3 | Serious eye damage/eye irritation | Category 2A-2B | Warning | H319: Causes serious eye irritation |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P337+P313: If eye irritation persists: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. |
It was set as Category 2A-2B from description that irritation was admitted by the test using the rabbit (UCLID (2000)). Since reparable is unknown, detailed categorization is not made. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | Although there is descriptive which suggests a possibility of causing asthmatic allergic to HSFS (2000), there is no report of a concrete case, and since data is insufficient, it cannot be classified. |
4 | Skin sensitization | Classification not possible | - | - | - | - | Although there is descriptive which suggests a possibility of causing skin allergy to HSFS (2000), there is no report of a concrete case, and since data is insufficient, it cannot classify. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Since data is insufficient only the information of the data of the in vitro reverse mutation test, and it cannot be classified. |
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 | - | - | - | - | Insufficient data available. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |

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 ... |
It was classified into Category 3 from 96-hour LC50=46-68mg/L of fishes (Golden orfe) (IUCLID, 2000). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | It is considered that toxicity factor is reduction of dissolved oxygen, but toxic effect was eased in environmental water. |
