Based on a report of an LC50 value (7 hours) of 8,200 mg/m3 (converted 4-hour equivalent value: 1,779 ppm) (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008)) for rats, this substance was classified in Category 3. Besides, a reference value in the unit of ppm was applied as vapour without mist, as the LC50 value is less than 90% of the saturated vapor concentration (1,974 ppm (12,081 mg/m3)). |
| 1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified |
- |
- | - | Based on a report of an LC50 value (4 hours) of 17.6 mg/L for rats (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008)), this substance was classified as "Not classified." Besides, the reference value for mist was applied as the LC50 value is greater than the saturated vapor concentration (1,974 ppm (12,081 mg/m3)). The category was revised by adding the new information obtained for this investigation. |
| 2 | Skin corrosion/irritation | Category 2 |
Warning |
H315 | P302+P352 P332+P313 P362+P364 P264 P280 P321 |
There are descriptions that this substance is irritating to the skin and causes erythema and pain on contact with the skin (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008)). From the above, this substance was classified in Category 2. Besides, it is reported that strong irritation occurred after 24-hour occlusive application of this substance in a skin irritation test with rabbits (DFGOT vol. 1(1991)). However, it was not used for this classification as it is the result of 24-hour application. |
| 3 | Serious eye damage/eye irritation | Category 2A |
Warning |
H319 | P305+P351+P338 P337+P313 P264 P280 |
It was reported that in an eye irritation test with rabbits, 24-hour application of 0.1 mL of this substance resulted in slight to severe chemosis and slight corneal opacity (DFGOT vol. 1 (1991), BUA 8 (1987)). In addition, there are descriptions that this substance is irritating to the eye and causes pain on contact with the eye (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008)). As above, based on reports of severe symptoms, this substance was classified in Category 2A. |

- | - | As for in vivo, this substance was positive in a micronucleus test with bone marrow cells of mice dosed intraperitoneally (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008), DFGOT Vol. 1 (1990), EHC 128 (1991), IARC 73 (1999)) and negative in a chromosome aberration test with the bone marrow cells of Chinese hamsters dosed orally (BUA 133 (1996)). As for in vitro, this substance was negative in bacterial reverse mutation tests (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008), ATSDR (2006), DFGOT Vol. 1 (1990), IARC 73 (1999), EHC 128 (1991)). From the above, the positive finding in the in-vivo bone marrow micronucleus test was considered unsuitable for use in evaluation (DFGOT Vol. 1 (1990)), and this substance was classified as "Classification not possible" according to the GHS Classification Guidance for the Japanese Government. |
| 6 | Carcinogenicity | Classification not possible |
- |
- | - | There is no information available for the classification in terms of carcinogenicity of this substance, in either humans or experimental animals. The IARC classified this substance in Group 3 (IARC vol. 73 (1999)). In terms of other carcinogenicity classifications, the EPA classified this substance as "D (Not classifiable as to human carcinogenicity)" (IRIS Summary (Access on August 2015)) in 1990. From the above, this substance was classified as "Classification not possible" for this hazard class. Besides, because of the revision of the GHS Classification Guidance for the Japanese Government, which was used as a classification criteria, the classification result was changed from the previous one ("Not classified"). |
| 7 | Reproductive toxicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, while there is a description that no effects of either maternal toxicity or fetal developmental toxicity were observed at up to 200 mg/kg/day in a developmental toxicity study with pregnant rats given this substance by gavage during organogenesis (gestation days 6 to 15), this report is considered inadequate as it consists only of a summary without details of the method and results of the study (ATSDR (2006), DFGOT MAK Value Documentation (2013), HSDB (Access on August 2015)). |
| 8 | Specific target organ toxicity - Single exposure | Category 1 (liver), Category 3 (respiratory tract irritation, narcotic effects) |

P308+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312 |
This substance causes respiratory tract irritation (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008), EHC 128 (1991)). It is reported that this substance causes cough, lethargy, and sore throat through inhalational exposure and causes diarrhea, nausea, and vomiting through ingestion (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008)), although there are no details specifying whether this pertains to humans or experimental animals. It is also reported that oral administration of this substance to mice at 300 mg/kg (equivalent to Category 1) caused liver damage with significantly increased liver weights and serum ALT activity and extensive centrilobular hepatocyte necrosis (IARC 73 (1999)). It is described that oral administration of this substance to mice at doses of not less than 1,000 mg/kg (equivalent to Category 2) caused ataxia, labored breathing (EHC 128 (1991)), and depression of the central nervous system (narcotic effects) (EHC 128 (1991)). From the above, this substance causes respiratory tract irritation, narcotic effects, and effects on the liver, therefore, was classified in Category 1 (liver) and in Category 3 (respiratory tract irritation, narcotic effects). |
| 9 | Specific target organ toxicity - Repeated exposure | Category 2 (liver) |
Warning |
H373 | P260 P314 P501 |
There is no information on humans. In experimental animals, a 10-day oral toxicity test with rats dosed by gavage revealed increased liver weights, hepatic degeneration (vacuolization and swelling) at 368 mg/kg/day (converted guidance value: 40.9 mg/kg/day), which is within the range of Category 2; a 90-day oral toxicity test (gavage) revealed increased liver weights, hepatocellular alterations, and hepatocellular necrosis at 147-588 mg/kg/day, which exceeds the range of Category 2 (Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008), ATSDR (2006)). Besides, this 90-day test also revealed increased GOT (AST) and cholesterol levels (males), reduced LDH levels (males), decreased thyroid follicular colloid density, and vacuolization of the cells of the adenohypophysis (in males) at 9 mg/kg/day, which is within the range of Category 1, however, these findings were not adopted for this classification as they were considered to be secondary findings associated with hepatic enzyme induction. In addition, a 28-day oral toxicity test with rats dosed by gavage revealed increased liver weights and enzyme induction in the liver (without histopathological alterations) at 100 mg/kg/day (converted guidance value: 31.1 mg/kg/day), which is within the range of Category 2, and hepatocellular hypertrophy and slightly raised serum enzyme activity at 500 mg/kg/day (converted guidance value: 155.6 mg/kg/day), which exceeds Category 2 (BUA 133 (1996), Environmental Risk Assessment for Chemical Substances Vol.6 (Ministry of the Environment, 2008)). Therefore, this substance was classified in Category 2 (liver). |
