2 | Skin corrosion/irritation | Not classified |
- |
- | - | [Rationale for the Classification] Although human and animal test data are not available, reliable in vitro data (1) indicate Category 3. Therefore, it was classified as "Not classified" (Category 3 in UN GHS classification). Besides, the category was changed from the previous classification by using new information. [Evidence Data] (1) There is a report that in an in vitro study (OECD TG 439 (reconstituted human epidermis test method), GLP-compliant), in which this substance was applied to human epidermis cells for 15 minutes, at the time of observation after 42 hours, no irritation was observed (REACH registration dossier (Accessed Aug. 2018)). |

H318 | P305+P351+P338 P280 P310 |
[Rationale for the Classification] Although human and animal test data are not available, it was classified in Category 1 based on reliable in vitro data (1). Besides, the category was changed from the previous classification by using the new information. [Evidence Data] (1) There is a report that since in an in vitro test (OECD TG 437 (Bovine Corneal Opacity and Permeability (BCOP) test), GLP-compliant), in which a 20% solution of this substance was applied to isolated bovine corneas for 4 hours, in vitro irritancy score (IVIS) of 109.3 (IVIS of 64.8 for positive control) was obtained, this substance shows serious damage to the eyes (REACH registration dossier (Accessed Aug. 2018)). |

4 | Skin sensitization | Classification not possible |
- |
- | - | [Rationale for the Classification] Information (1) indicating that this substance is not a skin sensitizer is also obtained, however, not enough evidence to determine "Not classified" is obtained, therefore, it was classified as "Classification not possible." Besides, the category was changed from the previous classification by using new information. [Evidence Data] (1) There is a report that this substance was not sensitizing in an LLNA test (OECD TG 442B, GLP test) with mice (REACH registration dossier (Accessed Aug. 2018)). |

8 | Specific target organ toxicity - Single exposure | Category 2 (nervous system, respiratory organs), Category 3 (narcotic effects) |
Warning |

P308+P311 P260 P264 P270 P405 P501 P304+P340 P403+P233 P261 P271 P312 |
[Rationale for the Classification] Based on (1), since symptoms of the nervous system such as twitching and trembling and anesthesia were observed within the range of Category 2, it can be classified in Category 2 (nervous system), Category 3 (narcotic effects). In addition, based on (2), it can be classified in Category 2 (respiratory organs) because flatulence was observed at doses within the range of Category 2. Therefore, it was classified in Category 2 (nervous system, respiratory organs), Category 3 (narcotic effects). [Evidence Data] (1) There is a report that in a single oral administration test with rats, apathy, staggering, cyanosis, diarrhea, twitching, trembling, rattling, dyspnoea, anesthesia, etc. were observed at 316-1,000 mg/kg/day (within the range of Category 2) (REACH registration dossier (Accessed Aug. 2018)). (2) In a single inhalation exposure test (4 hours) with rats, at 1.07-4.16 mg/L (within the range of Category 2), discharge of the eye and nose, and reddish encrusted nose as irritation symptoms to the nose were observed. Other than these, dyspnoea, staggering gait, apathy, and in the dead animals, flatulence, etc. were observed (REACH registration dossier (Accessed Aug. 2018)). |

9 | Specific target organ toxicity - Repeated exposure | Category 1 (teeth, bone) |
Danger |
H372 | P260 P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1 (teeth, bone). In (2), there are descriptions that the teeth, bone and kidneys are target organs, and that findings on the teeth and bone indicated typical fluorosis. However, since no histopathological abnormalities were observed in the kidney, this was judged to be excluded from target organs. Besides, a target organ was newly added by adopting new information sources. [Evidence Data] (1) In humans, bone lesions associated with fluorosis due to occupational exposure to inorganic fluoride are reported (ACGIH (7th, 2001)). (2) There is a report that in a test with rats dosed by feeding, pronounced impairment of enamel of the incisors at or above 900 ppm (converted value: 14 mg/kg/day, within the range of Category 2), and teeth whitening and increased BUN at 3000 ppm (converted value: 46.7 mg/kg/day, within the range of Category 2) were observed (REACH registration dossier (Accessed Aug. 2018)). |
