[Rationale for the Classification] Based on (1) and (2), it was classified in Category 2. [Evidence Data] (1) There is a report that in an in vitro skin irritation test (OECD TG439, GLP), a result of a cell viability of below 50% (28%) was obtained and this was judged as irritating (REACH registration dossier (Accessed Oct. 2018)). (2) There is a report that in an in vitro skin corrosion test (OECD TG 431, GLP), since the cell viabilities after a 3-minute and 1-hour exposure were 95% and 92%, respectively, which exceeding the criteria of 50% and 15%, respectively, it was concluded that this substance was not corrosive (REACH registration dossier (Accessed Oct. 2018)). |
3 | Serious eye damage/eye irritation | Not classified |
- |
- | - |
[Rationale for the Classification] Based on (1) and (2), it was classified as "Not classified." [Evidence Data] (1) There is a report that in an in vivo eye irritation test (OECD TG405, GLP, n=3) with rabbits, the conjunctival redness score was 1.1 and the conjunctival edema score was 0.3. They resolved in 7 days (REACH registration dossier (Accessed Oct. 2018)). (2) There is a report that in an in vitro corrosion/irritation test (OECD TG437, GLP) with bovine corneas, the IVIS (irritancy score) value was less than 55 (average 7.4), and it was concluded that it was not corrosive nor a severe irritant (REACH registration dossier (Accessed Oct. 2018)). |

[Rationale for the Classification] Classification not possible due to lack of data. |
4 | Skin sensitization | Classification not possible |
- |
- | - |
[Rationale for the Classification] Although (1) is obtained, there are no human data and animal data is limited. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) There is a report that in an LLNA test (OECD TG429, GLP) with mice, as a result of application of 5% and 10% solutions (propylene glycol) of this substance, Since Stimulation Index (SI) was 0.5 and 1.1, both less than 3.0, this substance was determined to be not sensitizing (REACH registration dossier (Accessed Oct. 2018)). |
5 | Germ cell mutagenicity | Classification not possible |

[Rationale for the Classification] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) There is a report that it was negative in a bacterial reverse mutation test (OECD TG 471, GLP) (REACH registration dossier (Accessed Oct. 2018)). |

Danger |
H370 |
P308+P311
P260 P264 P270 P321 P405 P501 |
[Rationale for the Classification] Based on (1) and (2), the central nervous system is considered to be the target based on the symptoms of sedation, convulsions, coma, etc., and these effects occurred within the range of Category 1. Therefore, it was classified in Category 1 (central nervous system). In addition, central nervous system symptoms are also observed in reference data (3) and (4), but no symptoms suggesting other target organs are observed. [Evidence Data] (1) In a single oral administration test with rats, sedation, clonic convulsions, dacryorrhea, and coma (frequently) were observed. There is a report that the LD50 value in this study was 47 mg/kg, and the mortality rates in the 30, 36, 43, 52 and 62 mg/kg dose groups were 0/10, 1/10, 4/10, 7/10 and 7/10, respectively (REACH registration dossier (Accessed Oct. 2018)). (2) There is a report that in a single oral administration test with rats, convulsions, tremors, sagging eyelids, wetness of the nose and mouth area, flaccid muscle tone, prostration, lethargy, spasms, ataxia and eye closure were observed prior to death. The LD50 value in this study was 55 mg/kg, and 1/2 deaths at a dose of 55 mg/kg and 2/2 deaths at 175 mg/kg were observed (REACH registration dossier (Accessed Oct. 2018)). [Reference Data, etc.] (3) There is a report that in a single oral administration test with rats, prostration and lethargy prior to death, and lethargy, few feces and wetness of the anogenital area in the surviving animals were observed. The LD50 in this study was 171.9 mg/kg (REACH registration dossier (Accessed Oct. 2018)). (4) There is a report that in a single dermal administration test with rabbits, lethargy and wetness of the nose/mouth area prior to death, and lethargy, few feces and diarrhea in the surviving animals were observed. The LD50 value in this study was between 200 mg/kg and 500 mg/kg (REACH registration dossier (Accessed Oct. 2018)). |

Danger Warning |
H372
H373 |
P260
P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1), since effects on the liver were observed at doses within the range of Category 2, it can be classified in Category 2 (liver). In addition, it can be classified in Category 1 (central nervous system) since lethargy was observed within the dose range of Category 1. Other than these, since atrophy of the thymus is considered to be a nonspecific effect reflecting the general condition, it was classified in Category 1 (central nervous system), Category 2 (liver). [Evidence Data] (1) In a 90-day study with rats dosed by gavage, effects on the liver (increased relative and absolute weight, increases in AST, ALT, ALP, the bilirubin value and bile acid, hepatocytes hypertrophy (female)) were observed at 30 mg/kg/day, which is within the range of Category 2. Hepatocellular hypertrophy was also observed in females in the groups of 3 and 10 mg/kg/day, but increased serum liver-derived enzyme activity was not observed, and the findings of the liver at these doses were considered to be within adaptive changes. In addition, deaths (2 males), decreased thymus weight and thymus atrophy (female), and symptoms such as lethargy, piloerection and ptosis were observed. It is reported that symptoms such as lethargy, piloerection and ptosis were also observed at 10 mg/kg/day within the range of Category 1, but this was less frequent and less severe than in the group of 30 mg/kg/day (REACH registration dossier (Accessed Oct. 2018)). |
