[Rationale for the Classification] Based on (1), it was classified in Category 1. [Evidence Data] (1) This substance is a strong alkali, and it is a strong irritant to the mucous membrane and the skin (HSDB (Access on June 2019)). [Reference Data, etc.] (2) This substance was classified in "Skin Corr. 1B (H314)" in the EU CLP classification (EU CLP classification (Access on August 2019)). |

[Rationale for the Classification] Based on (1) and (2), since the results of all standard combination tests, including in vivo and in vitro tests, were negative, it was classified as "Not classified." [Evidence Data] (1) As for in vivo, a negative result was reported in a micronucleus test with mouse bone marrows (REACH registration dossier (Access on August 2019)). (2) As for in vitro, negative results were reported in a bacterial reverse mutation test and a mouse lymphoma assay (REACH registration dossier (Access on August 2019)). |

Warning |
H335 |
P304+P340
P403+P233 P261 P271 P312 P405 P501 |
[Rationale for the Classification] Based on (1), it is considered that respiratory tract irritation occurs by inhalation exposure. Therefore, it was classified in Category 3 (respiratory tract irritation). Since ICSC (J) used in the previous classification is an information source in List 3, and details were unknown, it was not adopted. The classification result was changed from the previous classification by the use of the new information source. [Evidence Data] (1) There is a description that this substance is irritating to the skin and the mucous membranes (HSDB (Access on June 2019)). |

11 | Hazardous to the aquatic environment Short term (Acute) | Category 1 |

P273
P391 P501 |
It was classified in Category 1 from 48-hour LC50 = 0.55 mg/L for crustacea (Daphnia pulex) (AQUIRE, 2019, Lee, 1976). |
11 | Hazardous to the aquatic environment Long term (Chronic) | Not classified |
- |
- | - | Reliable chronic toxicity data were not obtained. Although the dynamics of the inorganic compound are unclear in the environment, it was thought that after dissociation in water, the aqueous solution becoming strongly alkaline is the main reason for its toxicity. Because a toxicity effect will be diminished by a buffering action in the aquatic environment, it was classified as "Not classified." |
12 | Hazardous to the ozone layer | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
