|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Category 3 |  |
H301 |
P301+P310 P264 P270 P321 P330 P405 P501 |
On the basis of an LD50 value of 290 mg/kg bw for rats (IUCLID (2000)), it was classified in Category 3. |
| 1 | Acute toxicity （Dermal） | Not classified | - | - | - | On the basis of an LD50 value of >2000 mg/kg bw for rats (IUCLID (2000)), it was classified as "Not classified" in JIS classification (Category 5 or "Not classified" in UN GHS classification). |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | "Solids" according to GHS definition. |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | No data. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Category 4 |  |
H332 |
P304+P340 P261 P271 P312 |
On the basis of an LC50 valuse of 3.6 mg/L/4h for rats (IUCLID (2000)), it was classified in Category 4. Besides, due to a melting point of 100 degrees C and no vapour pressure data, it was considered as a test by an exposure of dust. |
| 2 | Skin corrosion/irritation | Not classified | - | - | - | From a result as "not irritating" in a test in which an 80 % aqueous solution was applied to rabbis (IUCLID (2000)), and from a report on an application of a 35% inclusion to guinea pig, rat, and miniature pig skins for 1 second to 1 hour, by which injuries were not observed (IUCLID (2000)), it was classified as "Not classified." |
| 3 | Serious eye damage/eye irritation | Category 2 | |
H319 |
P305+P351+P338 P337+P313 P264 P280 |
From "irritating" in a report on a test using rabbits (IUCLID (2000)), it was classified in Category 2. |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | No data. |
| 4 | Skin sensitization | Classification not possible | - | - | - | No data. |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | No data. |
| 6 | Carcinogenicity | Classification not possible | - | - | - |
No data. Besides, it is classified in A4 in fluorides in ACGIH carcinogenicity assessment (ACGIH (2001)). |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | No data. |
| 8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | No data. |
| 9 | Specific target organ toxicity - Repeated exposure | Category 2 (tooth, bone) |  |
H373 |
P260 P314 P501 |
In a 4-week diet administration test in rats, effects on teeth such as decoloration, lack of smoothness, a developmental disorder, a mineralization disorder, and enamel hypoplasia were observed at doses of 900 ppm (converted to 90-day equivalent quantity: 27.7 mg/kg/day) and more in macroscopy and microscopy. In addition, the mineralization disorder in bone tissue was also found at a dose of 3000 ppm (converted to 90-day equivalent quantity: 92.3 mg/kg/day) (IUCLID (2000)). Because the doses of the above effects correspond to Category 2 of a range of guidance values, it was classified in Category 2 (tooth, bone). Besides, a reported NOAEL is 300 ppm (converted to 90-day equivalent quantity: 9.2 mg/kg/day). |
| 10 | Aspiration hazard | Classification not possible | - | - | - | No data. |

H402 |
P273 P501 |
From 96-hour LC50 = 65 mg/L for fish (Lepomis macrochirus) (IUCLID, 2000), it was classified in Category 3. |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 3 | - |
H412 |
P273 P501 |
Reliable chronic toxicity data are not obtained. Due to no obtaining data on rapid degradability and acute toxicity Category 3, it was classified in Category 3. |
| 12 | Hazardous to the ozone layer | Classification not possible | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
