Rat LD50 value=96mg/kg, 115mg/kg and 200mg/kg (IUCLID(2000)). Calculated based on the data above. However, the calculation value was lower than the lowest value of the above data, the lowest value was adopted to classify as category 3. | |
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 | - | - | - | - | Classification not possible due to lack of data |

2 | Skin corrosion/irritation | Category 1A-1C | Danger | H314: Causes severe skin burns and eye damage |
P301+P330+P331: IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. P303+P361+P353: IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P260: Do not breathe dust/fume/gas/mist/vapours/spray.

Described only irritating as a result of a rabbit examination (IUCLID (2000)). But there is description with corrosive irritant to skin as human impact (HSDB (Access on Jun 2005)). And also there is description that it was corrosive chemical (HSFS (1999)), it was set as Category 1A-1C. | |
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. |
It was described only as irritating as a result of the rabbit examination (IUCLID (2000)). However, we found the description that it is "corrosive irritant to skin" for effect on human body (HSDB (Access on Jun 2005)), and also we found a description that it was a corrosive chemical (HSFS (1999)). Therefore we classified it as Category 1. | |
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 | - | - | - | - | There is no data of a mutagenicity test and a genotoxicity study using the germ cell and somatic cell in the in vivo. And the result of the mutagenicity test in vitro is only the mutagenicity test (one each) using the bacteria indicated in RTECS of Priority2 (Access on Aug 2005) and IUCLID(2000). So it cannot classify. |
6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available |
8 | Specific target organ toxicity - Single exposure | Category 2 (respiratory system), Category 3 (respiratory tract irritation) | Warning |
H371: May cause damage to organs (respiratory system) H335: May cause respiratory irritation (respiratory tract irritation) |
P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P405: Store locked up. P501: Dispose of contents/container to ... P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. |
The substance was classified as Category 2 (respiratory organs) because it is reported in HSFS(1999) that it has irritant properties to nose, throat and lungs, and it causes shortness of breath and pulmonary edema at higher concentrations. Because there is also a report of the substance showing corrosive properties to skin, eyes and mucosa as effects on humans in HSDB (Access on Jun 2005), it was judged that the substance has airway irritant properties and it was classified as Category 3. | |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |

11 | Hazardous to the aquatic environment (Acute) | Category 1 | Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
It was classified into Category 1 from 96-hour TLm=0.0071-0.55mg/L of fishes (Fathead minnows) (HSDB, 2004). | |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Toxicity factor is considered to be strong base as aqueous solution, but toxic effect is eased by the buffer action in the environmental water. |
