[Rationale for the Classification] Based on (1), it was corresponding to Category 2 for rats, and based on (2)-(4), it was corresponding to Category 3 for rabbits. Therefore, it was conservatively classified in Category 2. [Evidence Data] (1) LD50 for rats: 161 mg/kg (BUA 263 (2007)) (2) LD50 for rabbits: 230 mg/kg (BUA 151 (1993), HSDB (Access on June 2019)) (3) LD50 for rabbits: 335 mg/kg (BUA 151 (1993)) (4) LD50 for rabbits: 230-335 mg/kg (BUA 263 (2007)) |

P403+P233 P261 P271 P311 P321 P405 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 3. Since the LC50 value was lower than 90% of the saturated vapor concentration (6408.4 ppm), the reference value in units of ppm was applied as a vapor without a mist. Besides, the category was changed from the previous classification by the use of the new information sources. [Evidence Data] (1) LC50 (4 hours) for rats: 3.81 mg/L (760.13 ppm) (GESTIS (Access on July 2019)) |

[Rationale for the Classification] Since effects were judged to be non-reversible based on (1), it was classified in Category 1. Besides, the category was changed due to the detailed information obtained. [Evidence Data] (1) In a skin irritation test with rabbits according to OECD TG 404, the mean scores at 24/48/72 hours were 3-3.67 for erythema and 3.3 for edema. Erythema of 2/3 animals was not fully reversible in 21 days (REACH registration dossier (Access on July 2019)). [Reference Data, etc.] (2) As for a human case, a worker had the back of his hand and his forearm exposed to a 1.5 M solution (M/ethanol) of this substance, and reddening and blistering of the skin developed in 1 hour. The lesions healed within 10 days, leaving small scars (GESTIS (Access on June 2019)). (3) In a skin irritation test in which this substance was administered to rabbits by semi-occlusive application for 4 hours, slight to severe erythema by 14 days and very slight to severe edema by 7 days were observed. The reactions were considered to be reversible, and it was judged as an irritant (BUA 151 (1993)). (4) This substance is toxic by ingestion, inhalation and skin absorption and is a strong irritant and a lacrimator (NTP DB (Access on June 2019)). It was classified as "Skin Irrit. 2 (H315)" in the EU-CLP classification (EU CLP classification (Access on August 2019)). |

[Rationale for the Classification] Since it was judged to be a skin irritant (Category 1) based on (1), it was classified in Category 1. Besides, the category was changed due to the new information obtained. [Evidence Data] (1) In a skin irritation test with rabbits according to OECD TG 404, the mean scores at 24/48/72 hours were 3-3.67 for erythema and 3.3 for edema. Erythema of 2/3 animals was not fully reversible in 21 days. Therefore, it was classified in "Skin Category 1 (corrosion)" (REACH registration dossier (Access on July 2019)). [Reference Data, etc.] (2) In an eye irritation test with rabbits, it was judged to be a strong eye irritant (BUA 151 (1993)). (3) There is a description that it is strongly irritating to humans (HSDB (Access on June 2019)). |

P333+P313 P362+P364 P261 P272 P280 P321 P501 |
[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1. [Evidence Data] (1) It is described that it strongly sensitized animals in a skin sensitization test with guinea pigs (maximization test) (BUA 151 (1993)). (2) It is described that 5/20 animals were sensitized (positive rate 25%) in a skin sensitization test with guinea pigs according to OECD TG 406 (BUA 151 (1993), REACH registration dossier (Access on July 2019)). [Reference Data, etc.] (3) There was a report of a positive reaction to this substance in a patch test in humans (GESTIS (Access on June 2019)). (4) There was a report on cross-reactivity to chloroacetic acid methyl ester in a skin sensitization test with guinea pigs on this substance (GESTIS (Access on June 2019)). |
5 | Germ cell mutagenicity | * |
- |
- | - |
[Rationale for the Classification] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, there was a report of a negative result in a bacterial reverse mutation test (NTP DB (Access on June 2019)). |
6 | Carcinogenicity | * |
- |
- | - |
[Rationale for the Classification] There are no classifications by other organizations. Therefore, classification was not possible due to lack of data. [Reference Data, etc.] (1) Tumorigenic was not observed in a subcutaneous injection of this substance to mice (NTP DB (Access on June 2019)). (2) An equivocal result for induction of lung adenomas was obtained by an intraperitoneal injection of this substance to strain A mice (NTP DB (Access on June 2019)). |

[Rationale for the Classification] Based on (1) and (2), since effects on the respiratory organs and central nervous system were observed, it was classified in Category 1 (respiratory organs), Category 3 (narcotic effects). The classification results were changed from the previous classification by the use of the new information sources. [Evidence Data] (1) The major consequence after inhalation exposure to this substance was considered to be the risk of severe lung damage. Moreover, narcosis was also one of the highlighted effects (GESTIS (Access on June 2019)). (2) In a 4-hour single inhalation exposure test with rats, at 0.83-7.5 mL/m3 (converted value based on the density, 1.15 g/cm3: 0.95-8.63 g/m3 = 0.95-8.63 mg/L) of the aerosol of this substance, increased respiratory rate, irregular breathing, panting, tremor, balance disorder, ataxia, drowsiness, analgesia and hyporeflexia were observed (REACH registration dossier (Access on September 2019)). [Reference Data, etc.] (3) Despite no descriptions of whether effects were observed in humans or experimental animals, there was a description that pronounced systemic effects such as drowsiness, vertigo, hyporeflexia and respiratory disorders were observed after application of even minor doses (GESTIS (Access on June 2019)). |
