---|---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 4 |
Warning |
H302 | P301+P312 P264 P270 P330 P501 |
Based on the rat LD50 value of 1.41 mL/kg (= 1635 mg/kg) (PATTY, 5th (2001)), the substance was classified as Category 4. | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
1 | Acute toxicity (Dermal) | Category 3 |
Danger |
H311 | P302+P352 P361+P364 P280 P312 P321 P405 P501 |
Based on the rabbit LD50 value of 0.53 mL/kg (= 610 mg/kg) (PATTY, 5th (2001)), the substance was classified as Category 3. | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |

2 | Skin corrosion/irritation | Not classified |
- |
- | - | In the rabbit test, only slight erythema and edema were observed (PATTY, 5th (2001)). In other rabbit test (OECD TG 404), no irritating effect was reported (IUCLID (2000)). Based on these documents, the substance was classified as "Not classified" in the JIS classification (Category 3 in the UN-GHS classification). As relevant notes, irritating effects were reported in other rabbit test in 24-hour application (IUCLID (2000)). | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
3 | Serious eye damage/eye irritation | Category 2B |
Warning |
H320 | P305+P351+P338 P337+P313 P264 |
The substance was classified as Category 2B based on the documented case of "slightly irritating" resulted from the rabbit test (OECD TG 405) (IUCLID (2000)). In other rabbit tests, highly irritating, or mild irritating were reported (IUCLID (2000)). | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |

5 | Germ cell mutagenicity | Not classified |
- |
- | - | The classification was concluded as "Not classified" based on the negative results in the micronucleus test using erythrocytes of mice orally administered (in vivo mutagenicity test in somatic cells) (PATTY, 5th (2001)). As relevant information, as for in vitro study, negative results in the Ames test were reported (PATTY, 5th (2001), IUCLID (2000)). | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
6 | Carcinogenicity | Classification not possible |
- |
- | - | No data available. | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | No data available. | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | Because the single dermal application of 0.5 or 2 g/kg to rats did not cause deaths or induce any systemic effects (PATTY, 5th (2001)), the classification for dermal route corresponded to "Not classified". However, the classification for specific target organ toxicity (single exposure) was determined as "Classification not possible" due to no available data for the other routes (oral, inhalation). | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | In the 4-week repeated dermal toxicity study in rats, slight increase in leukocyte count and reduced serum levels of reduced and oxidized glutathione were noted in the high dose group at 500 mg/kg/day (converted dose level as that of 90-day study: 153.8 mg/kg/day) except the local effects of the skin, and no serious toxic effects were seen (PATTY, 5th (2001), IUCLID (2000)). Therefore, the classification for dermal route corresponded to "Not classified". However, the classification for specific target organ toxicity (repeated exposure) was determined as "Classification not possible" due to no available data for the other routes (inhalation, oral). | FY2010 | GHS Classification Guidance by the Japanese Government (July, 2010) |
