1 | Acute toxicity (Oral) | Category 4 |

P301+P312
P264 P270 P330 P501 |
It was classified in Category 4 based on reports on LD50 values for rats of 1,367 mg/kg (females), 1,540-2,000 mg/kg (males) (JECDB (Access on August 2013)), and 1,780 mg/kg (PATTY (6th, 2012)). |

3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, it is described in PATTY (6th, 2012) that there was slight irritation in the eye of rabbits, but it was not adopted for classification because the details are unknown. |

5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. There are no in vivo data, and as for in vitro, it was negative in a bacterial reverse mutation test and positive in a chromosomal aberration test with cultured mammalian cells (JECDB (Access on September 2013)). |
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, no reproductive and developmental toxicity was observed in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with rats in the oral route (gavage) (JECDB (Access on October 2013), PATTY (6th, 2012), HSDB (Access on October 2013)). Because it is the result of a screening test, and there are no sufficient reports on developmental toxicity, it was classified as "Classification not possible." |
8 | Specific target organ toxicity - Single exposure | Category 2 (kidney, liver, spleen, thymus) |
Warning |
H371 |
P308+P311
P260 P264 P270 P405 P501 |
In a gavage administration test with rats (JECDB (Access on October 2013)), a decrease in spontaneous activity, salivation, prone position, subnormal temperature, bradypnea, and diarrhea were observed in the surviving animals at the doses (910-2,000 mg/kg) within the guidance value range. Histopathological examinations revealed ulcer, thickening of the mucosal layer, granulation growth in the submucosal tissue, etc. in the forestomach and regeneration of the tubular epithelium and fibrosis in the kidney. And atrophy and an increase in extramedullary hematopoiesis in the spleen were observed. The dead animals showed necrosis of the mucosal epithelium in the forestomach, focal necrosis and congestion of hepatocytes, necrosis and atrophy of the tubular epithelium in the kidney, necrosis in the spleen, congestion of the lung and edema in the alveoli, and atrophy of the thymus and thymic cyst. Among these, the findings in the forestomach were thought to be caused by irritation of the substance, and the findings in the lung were thought to be those at an agonal stage. Therefore, these were not taken as the target organs. Based on the findings except those of the forestomach and lung, it was classified in Category 2 (kidney, liver, spleen, thymus). |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (thymus) |
Warning |
H373 |
P260
P314 P501 |
In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with rats by gavage exposure, thickening of the mucosa and hyperkeratosis in the forestomach at or above the low dose (converted guidance value: 5.5 mg/kg/day) corresponding to Category 1, edema in the submucosal tissue and ulcer in the forestomach and atrophy of the thymus at the middle dose (converted guidance value: 15 mg/kg/day; corresponding to Category 2), and increased absolute and relative weights of the liver and kidney at the high dose (50 mg/kg/day; corresponding to Category 2) were observed (JECDB (Access on October 2013), HSDB (Access on October 2013), PATTY (6th, 2012)), but among these, the findings in the forestomach were thought to be caused by irritation of the substance. Furthermore, increased weights of the liver and kidney were not accompanied by relevant blood chemical findings and pathological changes, and the organs except for the thymus were excluded because their findings were not thought to be of significance in toxicity. From the above, it was classified in Category 2 (thymus). |

From 72-hour EbC50 = 1.1 mg/L (SIDS, 2004) for algae (Pseudokirchneriella subcapitata), it was classified in Category 2. |

Chronic toxicity data for algae were obtained, but it is not possible to use it for classification because it is of low reliability although chronic toxicity is suspected by considering acute toxicity. 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 (a degradation rate by BOD: 93% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1995; SIDS, 2004)), and a low bioaccumulation estimate (Log Pow = 2.12 (SIDS, 2004)) despite 72-hour EC50 = 2.4 mg/L for fish (Oryzias latipes) (SIDS, 2004). From the above, although chronic toxicity data usable for classification were obtained for algae, chronic toxicity was suspected, therefore it was classified as "Classification not possible" by expert judgment. |
