---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, there is a report on an LD50 value of 316-464 mg/kg for rats (ECHA (Access on October 2013)). This information was not used for classification because it is from the information source outside the List. |
1 | Acute toxicity (Dermal) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, there is a report on an LD50 value of > 400 mg/kg for rabbits (ECHA (Access on October 2013)). This information was not used for classification because it is from the information source outside the List. |

5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, as for in vitro, there is information that it was negative in all of a bacterial reverse mutation test, a gene mutation test (hgprt gene locus) with cultured mammalian cells, and a micronucleus test with cultured V79 cells of Chinese hamsters (ECHA (Access on September 2013)). This information was not used for classification because it is from the information source outside the List. |
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. Besides, in ECHA (Access on October 2013), in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG 422) with rats in the oral route (gavage), reproductive toxicity was not observed at the doses where general toxicity was found in parent animals. Furthermore, likewise in NITE Chemical Risk Information Platform (NITE-CHRIP), and Safety Test (Ministry of Economy, Trade and Industry (METI) (Access on October 2013)), in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG 422) with rats in the oral route (gavage), reproductive toxicity was not observed at the dose where general toxicity was found in parent animals. The above information was not used for classification because it is from the information source outside the List. |
8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, in ECHA (Access on October 2013), there is a report on transient dyspnea, apathy, staggering, spastic gait, etc. in gavage administration to rats at concentrations (215-464 mg/kg) within the guidance value ranges for Category 1-2. This information was not used for classification because it is from the information source outside the List. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, the following test results are reported in NITE Chemical Risk Information Platform (NITE-CHRIP), Safety Test (Ministry of Economy, Trade and Industry (METI) (Access on October 2013)) and ECHA (Access on October 2013). In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test in which rats were dosed by gavage for 42 days from 14 days before mating for males and 42-47 days from 14 days before mating for females, vacuolated bronchial epithelium in the lung was observed at the dose (23.3 mg/kg/day (converted guidance value)) corresponding to Category 2 (NITE Chemical Risk Information Platform (NITE-CHRIP) (Access on October 2013)). In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test in which rats were dosed by gavage (males: for 30 days from 14 days before mating, females: from 14 days before mating to day 4 of lactation), decreased eosinophil counts were found at the dose (25 mg/kg/day (converted guidance value)) corresponding to Category 2, but this was thought to be effects of unspecific stress (ECHA (Access on October 2013)). The above information was not used for classification because it is from the information source outside the List. |

From 72-hour ErC50 = 71 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2008)), it was classified in Category 3. |

If chronic toxicity data are used, then it is classified as "Not classified" due to being not rapidly degradable (a degradation rate by BOD: 1% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 2005)), and 72-hour NOEC (r) = 9.4 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2008)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 3 due to being not rapidly degradable (a degradation rate by BOD: 1% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 2005)), and 48-hour EC50 = 78 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2008)). By drawing a comparison between the above results, it was classified in Category 3. |
