Based on the description that skin contact with this material may cause severe injury or necrosis (HSDB (Access on August 2017)), this substance was classified in Category 1. Besides, this substance was classified as "Skin. Corr. 1B, H314" in EU CLP classification (ECHA CL Inventory (Access on August 2017)). |
| 3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 |
P305+P351+P338
P280 P310 |
It is classified in Category 1 for skin corrosion/irritation. In addition, there is a description that skin contact with this substance may cause severe burns (HSDB (Access on August 2017)). Therefore, this substance was classified in Category 1. |
| 4 | Respiratory sensitization | Classification not possible |

Classification was not possible due to lack of data. There is no in vivo data on this substance. As for in vitro, a bacterial reverse mutation test was negative (HSDB (Access on August 2017)). Besides, for the genotoxicity of fluorine, it is stated by the Food Safety Commission of Japan that weak positive results were obtained in the in-vitro tests with mammalian cells, but in an in-vivo DNA damage test, it was judged as negative in a comprehensive manner, and it is considered that there is no genotoxicity which is a particular problem for living bodies (Risk Assessment Report (Beverages) (Food Safety Commission of Japan, 2012)). |
| 6 | Carcinogenicity | Classification not possible |

- | - | Classification not possible due to lack of data. |
| 7 | Reproductive toxicity | Classification not possible |

In humans, two cases were reported in which children exposed to detergents containing this substance developed marked hypocalcemia and ventricular fibrillation (HSDB (Access on August 2017)). In addition, there is a description that inhalation of dust of this substance may cause irritation of the respiratory system (HSDB (Access on August 2017)). From the above, it was classified in Category 1 (heart), Category 3 (respiratory tract irritation). In the previous classification, it was classified in Category 2 (Inhalation: lung) based on the description that it causes pulmonary edema due to exposure to high levels in humans (HSDB (2003), IUCLID (2000), SITTIG (4th, 2001)). However, it was not adopted because there is no description of pulmonary edema in HSDB (Access on August 2017), the information in IUCLID is not available at present, and SITTIG is the information source listed as List 3 and details are unknown. Therefore, the classification result was changed. |

P264 P270 P314 P501 |
In humans, there is no information on this substance. However, there is a report of lesions in bones related to fluorosis due to occupational exposure to inorganic fluoride in ACGIH's "FLUORIDES" (ACGIH (7th, 2001)). In addition, for fluorides, both beneficial and detrimental dental and skeletal effects have been observed in humans. Fluoride has been shown to decrease the prevalence of dental caries and, under certain conditions, has been used for the treatment of osteoporosis. However, it is described that excess fluoride can also result in dental fluorosis and can result in an increased prevalence of bone fractures in the elderly or patients with skeletal fluorosis (ATSDR (2003)). As for experimental animals, there is no information on this substance. Therefore, this substance was classified in Category 1 (teeth, bone). |
