There are two LD50 values for rats of > 2,000 mg/kg [OECD TG 401, GLP] (JECDB (Access on Dec. 2012)) and 1,770 mg/kg [FDA guideline, GLP] (USEPA/HPV (2002)), one of them corresponds to "Not classified," and the other corresponds to Category 4. It was classified in Category 4 by adopting a more hazardous category. |

5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | The classification is not possible due to no in vivo test data. Besides, as for in vitro, it is reported that it was negative in an Ames test (JECDB (2000), USEPA/HPV (2002)), negative in a chromosomal aberration test with CHL/lU cells (JECDB (2000)), positive in a chromosomal aberration test with CHO cells (HPVIS (2009)), and negative in a mouse lymphoma test (HPVIS (2009)). |

P308+P313
P201 P202 P280 P405 P501 |
In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test by oral administration to rats (OECD TG 422, GLP), both male and female parent animals (F0) showed decreased weight gain before mating or during mating at or above 50 mg/kg/day, while a statistically significant decrease in the number of total implantations/litter was observed in the high dose group (300 mg/kg/day) (HPVIS (2005)). Therefore, it was classified in Category 2. Besides, no effects on the numbers of pups or live pups per litter were found in any dose group, and there was no evidence of toxicity in F1 offspring. |
8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | In an acute oral toxicity test with rats (FDA guideline, GLP), red stains on the muzzle, piloerection, slight depression, brown-yellow stains on the urogenital area, rapid breathing, unkempt fur, etc. were observed at 625 or 1,250 mg/kg, and at 2,500 and 5,000 mg/kg, saliva-like stains on the muzzle and hunched posture were seen in addition to the above signs, and all the animals died (USEPA/HPV (2002)). It is reported that in another single administration test by oral administration to rats (OECD TG 401, GLP), diarrhea and reduced weight gain were found after the administration of 1,500 or 2,000 mg/kg, but there were no deaths, and no serious toxic signs were observed at 14-day observation after the administration (JECDB (Access on Dec. 2012)). It was hard to specify the target organ within the range of the above data, and effects are unknown at the limit value of the guidance values (2,000 mg/kg). Therefore, it was classified as "Classification not possible." |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (kidney) |
Warning |
H373 |
P260
P314 P501 |
It is reported that in a 28-day repeated oral administration toxicity test with rats (doses: 0, 100, 300, 1,000 mg/kg/day), granular casts, etc. in the kidney were observed in both males and females in the 1,000 mg/kg group (converted guidance value: 311 mg/kg) above the guidance value range, and an increase in drinking water and an increase in regeneration in the tubular epithelium (males), which were estimated to be related to kidney disorders, were found in the 300 mg/kg group (converted guidance value: 93.3 mg/kg) (JECDB (Access on Dec. 2012)). And in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test by oral administration to rats (OECD TG 422, GLP), dose-related lesions in the kidney were described as histopathological findings in the 300 mg/kg/day group (converted guidance value: 93.3 mg/kg/day) in males (HPVIS (2005)). Because the doses of the above findings correspond to the guidance values for Category 2, it was classified in Category 2 (kidney). Besides, findings in the liver were not adopted because they were just weight changes, not accompanied by histological changes at doses within the guidance value range. |

It was classified in Category 2 from 96-hour LC50 = 1.2 mg/L for fish (Oryzias latipes) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2004)). |

If chronic toxicity data are used, then it is classified in Category 2 due to being not rapidly degradable (not readily degradable, a degradation rate by BOD: 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 2002)), and 72-hour NOEC = 0.33 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, 2004)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 2 due to being not rapidly degradable (not readily degradable, a degradation rate by BOD: 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 2002)), and 96-hour LC50 = 1.2 mg/L for fish (Oryzias latipes) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2004)). From the above results, it was classified in Category 2. |
