---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | - | Based on its rat LD50 = 2250 mg/kg (HSDB (2004)), the substance was classified into "Not classified" in JIS classification (Category 5 in UN 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 | Classification not possible | - | - | - | - | No data available. |
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. |
Since in a Draize test using rabbits, the substance was severely irritating (RTECS (2008)) and it is rated Xi; R41 in the EU classification (EU-Annex I (accessed in September 2008)), it was classified into Category 1. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | It is documented that in an inhalation test using rats, increased humoral immune response was noted (RTECS (2008)). However, due to a lack of data, classification is not possible. |
4 | Skin sensitization | Category 1 | Warning | H317: May cause an allergic skin reaction |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P333+P313: If skin irritation or rash occurs: Get medical advice/attention. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P272: Contaminated work clothing should not be allowed out of the workplace. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment (see ... on this label). P363: Wash contaminated clothing before reuse. P501: Dispose of contents/container to ... |
It is documented that in a test using guinea pigs, the substance exhibited mild sensitizing properties (HSDB (2004)), and it is rated Xi; R42/43 in the EU classification. Therefore, the substance was classified in Skin sensitization Category 1. | |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | No data 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 oral administration test using rats for 30 days, at the dose of 1320 mg/kg (330 mg/kg/90 days) above the guidance value of Category 2, changes in total protein contents, bilirubin levels, and cholesterol levels were noted, and changes in cholinesterase and phosphoenzymes in tissue and blood were observed (RTECS (2008)). In a halation test using rats for 122 days (exposure durations are not shown), at the dose of 0.02 mg/L, respiratory depression and hepatic steatosis were observed (RTECS (2008)). However, since these data are List 3 data, and these tests do not provide details, and due to the lack of data, 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 | |
