1 | Acute toxicity (Oral) | Category 4 |
Warning |
H302 | P301+P312 P264 P270 P330 P501 |
From a reported LD50 value (OECD TG 423) of 300 to 2,000 mg/kg for rats (Japan Existing Chemical Data Base, Ministry of Health, Labour and Welfare (Access on October 2015)), it was classified in Category 4. |
1 | Acute toxicity (Dermal) | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable |
- |
- | - | "Solids" according to GHS definition. |

4 | Skin sensitization | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Namely, there are no in vivo data, and as for in vitro, a bacterial reverse mutation test and a chromosomal aberration test in cultured mammalian cells were negative (Japan Existing Chemical Data Base, Ministry of Health, Labour and Welfare (Access on October 2015)). |
6 | Carcinogenicity | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | In a combined repeated dose toxicity study with reproduction/developmental toxicity screening test (OECD TG 422) using rats, prolongation of gestation period and a decrease in a number of pups born were observed in maternal animals at 300 mg/kg/day where general toxic effects were apparent in parent animals (deaths (females 2/12), tissue injury in kidney and bladder (60 mg/kg/day or higher), tissue injury in forestomach and so on). However, out of death cases, one died at the end of gestation, and the other died during parturition, and it was considered that both perinatal deaths and difficult parturition were attributed to severe general toxic effects in maternal animals which resulted in prolongation of gestation period and a decreased number of pups born (Japan Existing Chemical Data Base, Ministry of Health, Labour and Welfare (Access on October 2015)). Moreover, it is thought that they were not reproductive effects specifically related to administration of this substance. Namely, reproductive/developmental effects related to administration of this substance were not detected in this test, but it cannot be classified as "Not classified" only by this result because it is a screening test, and there are no other data available. Therefore, the classification is not possible due to lack of data in this hazard class. |
8 | Specific target organ toxicity - Single exposure | Category 2 (gastrointestinal tract) |
Warning |
H371 | P308+P311 P260 P264 P270 P405 P501 |
There are no human data. As for experimental animals, decreased spontaneous motility, irregular breathing, and gastrointestinal tract disorder (distension of the stomach and small intestine, reddening in the mucous membrane of the glandular stomach, accumulation of red and clear ascitic fluid) were reported after oral administration in rats (2,000 mg/kg, corresponding to Category 2) (Japan Existing Chemical Data Base, Ministry of Health, Labour and Welfare (Access on October 2015)). From the above, because gastrointestinal tract disorder was observed for this substance, the substance was classified in Category 2 (gastrointestinal tract). |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (kidney, urinary bladder) |
Warning |
H373 | P260 P314 P501 |
There is no human information. As for experimental animals, in a combined repeated dose toxicity study with reproduction/developmental toxicity screening test using rats in gavage administration, necrosis of tubular epithelium and hyperplasia of pyelic epithelium in the kidney and hyperplasia of mucous membrane epithelium in bladder were observed at 60 mg/kg/day within a range of Category 2 (converted to a 90-day equivalent: males 28 mg/kg/day) (Japan Existing Chemical Data Base, Ministry of Health, Labour and Welfare (Access on October 2015)). Therefore, the substance was classified in Category 2 (kidney, bladder). |

---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Category 1 |
Warning |
H400 | P273 P391 P501 |
From 96-hour LC50 = 0.88 mg/L for fish (Oryzias latipes) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2004), it was classified in Category 1. |
11 | Hazardous to the aquatic environment (Long-term) | Category 3 |
- |
H412 | P273 P501 |
If chronic toxicity data are used, then it is classified in Category 3 due to rapid degradability (a degradation rate by 28-day O2 consumption/BOD = 96%, a degradation rate by TOC removal = 98%, a degradation rate by HPLC = 100% (Official Bulletin of Economy, Trade and Industry, 2004) and a degradation rate by 28-day BOD (NH3) = 96%, a degradation rate by HPLC = 100% (Official Bulletin of Economy, Trade and Industry, 2004)), 21-day NOEC (reproduction) = 0.29 mg/L for crustacea (Daphnia magna) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2005). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified as "Not classified" due to rapid degradability, and a low bioaccumulation estimate (log Kow = 0.47 (PHYSPROP Database, 2009)) although 96-hour LC50 = 0.88 mg/L for fish (Oryzias latipes) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2004). It was classified in Category 3 by drawing a comparison between the above results. |
