Rationale for the classification
1 Acute toxicity (Oral) Not classified
-
-
- - Based on the report that an LD50 value of 3.73 mL/kg (=3.049 mg/kg which was the converted value using 0.8174 g/cm3 at 20 deg C (Lide (85th, 2004))) for rats (ACGIH (7th, 2001)), it was classified as "Not classified" (Category 5 in UN GHS classification).
1 Acute toxicity (Dermal) Not classified
-
-
- - Based on the report that an LD50 value of 5.66 mL/kg (=4,626 mg/kg which was the converted value using 0.8174 g/cm3 at 20 deg C (Lide (85th, 2004))) for rabbits (ACGIH (7th, 2001)), it was classified as "Not classified" (Category 5 in UN GHS classification).
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Category 4


Warning
H332 P304+P340
P261
P271
P312
Based on a report of an LC50 (6 hours) value of 2,690 ppm (converted 4-hour equivalent value: 3,295 ppm) for rats (PATTY (6th, 2012), ACGIH (7th, 2001)), it was classified in Category 4. Besides, since the LC50 value was lower than 90% of the saturated vapor concentration (6,910ppm), the reference value in units of ppm was applied as a vapour without a mist.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - Classification not possible due to lack of data.
2 Skin corrosion/irritation Not classified
-
-
- - Based on descriptions that mild irritation was found in tests with rabbits or guinea pigs, and that after application to humans, mild irritation might occur, it was classified as "Not classified" (Category 3 in UN GHS classification). The category was revised according to the revision of the GHS classification guidance for the Japanese Government.
3 Serious eye damage/eye irritation Category 2


Warning
H319 P305+P351+P338
P337+P313
P264
P280
There are reports that mild irritation was noted in an eye irritation test with rabbits (PATTY (6th, 2012)), and that when rats were exposed to this substance at 2,000 ppm for 4 hours, eye irritation was observed (ACGIH (7th, 2001)). In addition, there is a report that after single application to humans, mild irritation might occur (PATTY (6th, 2012)). From the above results, it was classified in Category 2.
4 Respiratory sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
4 Skin sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
5 Germ cell mutagenicity Classification not possible
-
-
- - Classification not possible due to lack of data.
6 Carcinogenicity Classification not possible
-
-
- - Classification not possible due to lack of data.
7 Reproductive toxicity Classification not possible
-
-
- - Classification not possible due to lack of data.
8 Specific target organ toxicity - Single exposure Category 3 (respiratory tract irritation, narcotic effects)

In humans, based on descriptions that respiratory tract irritation was caused by inhalation exposure, and that depressed consciousness was caused at high concentrations (ACGIH (7th, 2001), PATTY (6th, 2012)), it was considered to have narcotic effects.
In experimental animals, there is a description of decreased respiration at 400 ppm, hypoactivity at 825 ppm, narcotic effects and death at 1,600 ppm and 3,220 ppm, and mucous membrane irritation at 2,000 ppm by inhalation exposure of rats (ACGIH (7th, 2001), PATTY (6th, 2012)).
The effects on experimental animals were judged to be due to irritation and narcotic effects, and it was classified in Category 3 (respiratory tract irritation, narcotic effects).
9 Specific target organ toxicity - Repeated exposure Classification not possible
-
-
- - There was no information in humans. As for experimental animals, although increases in relative weights of the liver and kidney, hepatocyte hypertrophy, and irritation and hyperkeratosis of the nonglandular gastric epithelium were noticed in a 12-week gavage study with rats administered at 1,000 mg/kg/day of this substance (5 days/week) (PATTY (6th, 2012), HSDB (Access on June 2014)), there are no test data that clearly show the effects through the oral route including this study, at or lower than the dose range of Category 2.
On the other hand, on inhalation exposure with rats to this substance at 1,200 ppm (5,592 mg/m3) (presumed to be a vapor) for 2 weeks, no abnormalities were observed except that a decreased response to stimulation during exposure and marginal liver enlargement in necropsy were observed (ACGIH (7th, 2001), HSDB (Access on June 2014)). Although the concentration where effects were observed corresponded to within the range of Category 2 (converted guidance value: 0.86 mg/L/6 hours), it was a short-term exposure test with only one concentration, and it was difficult to confirm with the original source (unpublished company data), therefore, the data was judged to be inappropriate for classification. Therefore, it was concluded that classification was not possible due to lack of data.
10 Aspiration hazard Classification not possible
-
-
- - This substance is a ketone composed of no more than 13 carbon atoms and had a kinematic viscosity of 0.0091 mm2/s (20 deg C, calculated by CERI), corresponding to Category 2. According to the GHS Classification Guidance for the Japanese Government, it was classified as "Classification not possible."
