1 | Acute toxicity (Oral) | Not classified |
- |
- | - | Based on a report of an LD50 value of 3,500 mg/kg (PATTY (6th, 2012), ACGIH (7th, 2001)) for rats, it was classified as "Not classified" (Category 5 in UN GHS classification). | FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
1 | Acute toxicity (Dermal) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, there is a report of an LD50 value of > 16,000 mg/kg (GESTIS (Access on August 2015), RTECS (Access on August 2015)) for rabbits. | FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |

1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified |
- |
- | - | There is a report that in a 4-hour exposure test with rats, there were no deaths at 3,000 ppm (15.72 mg/L), some deaths were observed at 3,484 ppm (18.26 mg/L), and 4 out of 6 animals died at 5,888 ppm (30.9 mg/L) (PATTY (6th, 2012)), and there is a report that in an 8-hour test with rats exposed at 6,000 ppm at 35 deg C (converted 4-hour equivalent value: 12,000 ppm (62.9 mg/L)), 4 out of 6 animals died (ACGIH (7th, 2001)). Since the result of the 4-hour test was adopted preferentially according to the GHS classification guidance for the Japanese government, it was classified as "Not classified." Besides, because the test concentrations were higher than the saturated vapor pressure concentration (2,631 ppm), the reference value as mist was applied. Information from newly obtained information sources (PATTY (6th, 2012), ACGIH (7th, 2001)) was added, and the category was reviewed. | FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, there is a description that this substance is slightly irritating to the skin (PATTY (6th, 2012)). However, it was judged to be inadequate data to classify it as "Not classified" (Category 3 in UN GHS classification). | FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
3 | Serious eye damage/eye irritation | Category 2 |
Warning |

There is a report that after rats or mice were exposed to the vapour of this substance for 4 hours, eye irritation was observed (ACGIH (7th, 2001)). In addition, as for humans, there is a report that transient corneal injury was observed when this substance in the liquid form made contact with the eye (ACGIH (7th, 2001)), and there is a report that eye irritation was observed in exposure to this substance (ACGIH (7th, 2001), HSDB (Access on August 2015)). From the above, it was classified in Category 2. | FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |

There are reports that this substance was irritating to the respiratory tract in humans and experimental animals (rats, mice) (ACGIH (7th, 2001), PATTY (6th, 2012)). In addition, there are reports that headaches and nausea by inhalation exposure in humans, and ataxia, hypoactivity, and coma by inhalation exposure at 6,000 ppm (31.5 mg/L) (the dose exceeding Category 2) in rats were observed, but these resolved (ACGIH (7th, 2001)). From the above, this substance is irritating to the respiratory tract and has narcotic effects, and it was classified in Category 3 (respiratory tract irritation, narcotic effects). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, there is a report that in a 13-week repeated dose toxicity test (unknown administration route) with rats, hypoactivity, decreased body weight gain and gamma-diketone neuropathy were observed at 410 mg/kg/day (converted guidance value: 296 mg/kg/day), which was outside the range for Category 2 (PATTY (6th, 2012)). Besides, this data is from an abstract and is considered to be poor in reliability. |
