1 | Acute toxicity (Oral) | Category 4 |
H302 |
P301+P312 P264 P270 P330 P501 |
On the basis of an LD50 value of 985 mg/kg for rats (OECD TG401, GLP) (Report on Toxicity Tests of Chemical Substances, MHLW (Access on Dec. 2010)), it was classified in Category 4. | |
1 | Acute toxicity (Dermal) | Category 4 |
H312 |
P302+P352 P280 P312 P322 P363 P501 |
Both LD50 values for rats, 1000-1250 mg/kg in males and 1030 mg/kg in females (OECD TG402, GLP) (IUCLID (2000)), correspond to Category 4. | |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | "Liquids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | No data. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | No data. |
2 | Skin corrosion/irritation | Category 1 |
H314 |
P301+P330+P331 P303+P361+P353 P305+P351+P338 P304+P340 P260 P264 P280 P310 P321 P363 P405 P501 |
On the basis of a result as "corrosive" in a test using rabbits (OECD TG 404: GLP) (IUCLID (2000), it was classified in Category 1. | |
3 | Serious eye damage/eye irritation | Category 2 |
H319 |
P305+P351+P338 P337+P313 P264 P280 |
From a result as "moderately irritating" in a test using rabbits (IUCLID (2000), it was classified in Category 2. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | No data. |
4 | Skin sensitization | Classification not possible | - | - | - | No data. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - |
The classification is not possible due to no in vivo test data. Besides, as in vitro tests, a positive in a Ames test (OECD TG471; GLP) (with the addition of S9mix), a negative in a chromosomal aberration test using Chinese hamster lung cells (OECD TG 473; GLP) (Report on Toxicity Tests of Chemical Substances, MHLW (Access on Dec. 2010)), and a negative in an HGPRT test using V79 cells (OECD TG 476; GLP) (IUCLID (2000)) are reported respectively. |
6 | Carcinogenicity | Classification not possible | - | - | - | No data. |
7 | Reproductive toxicity | Category 2 |
H361 |
P308+P313 P201 P202 P281 P405 P501 |
In a combined repeated dose toxicity study with reproduction/development toxicity screening test (OECD TG 422; GLP) in which rats were orally administrated from 14 days before mating, methemoglobinemia and anemia as general toxicities were initiated at doses of 20 mg/kg/day or higher in parent animals, but no adverse effects on sex cycle, copulation ability, and fertility, and no adverse effects during deliveries and pregnancy period were observed (Report on Toxicity Tests of Chemical Substances, MHLW (Access on Dec. 2010)). But in a high dose group (60 mg/kg), body weight on day 0 showed a low value in both sexes of newborns, and Viability Index on Day 4 after birth showed a statistically significant low value in newborn males and showed a low-value tendency in newborn females (Report on Toxicity Tests of Chemical Substances, MHLW (Access on Dec. 2010)), therefore it was classified in Category 2. |

8 | Specific target organ toxicity - Single exposure | Category 1 (blood) |
H370 |
P307+P311 P260 P264 P270 P321 P405 P501 |
On the basis of a report in which single-dose oral administration of 25 mg/kg, which corresponds to Category 1 in guidance values, to cats caused increased methemoglobin concentration and increased Heinz body (SIDS (2005)), it was classified in Category 1 (blood). | |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (blood system) |
H372 |
P260 P264 P270 P314 P501 |
On the basis of a report in which methemoglobinemia and anemia were initiated and changes, which were considered to be caused by those, such as general toxicities, hematological test results, excessive hematopoiesis in bone marrow, extramedullary hematopoiesis in liver and spleen were observed at doses of not less than 20 mg/kg (converted to a 90-day equivalent value: ca. 10 mg/kg/day), which corresponds to an upper limit of Category 1, in a combined repeated dose toxicity study with reproduction/development toxicity screening test (OECD TG 422; GLP) in which rats were orally administrated 6, 20, and 60 mg/kg/day (Report on Toxicity Tests of Chemical Substances, MHLW (Access on Dec. 2010)), it was classified in Category 1 (blood system). | |

11 | Hazardous to the aquatic environment (Acute) | Category 2 | - |
H401 |
P273 P501 |
It was classified in Category 2 from 48-hour EC50 = 1.5 mg/L for crustacea (Daphnia magna) (Ecotoxicity tests by Environment agency, 1998). |
11 | Hazardous to the aquatic environment (Long-term) | Category 1 |
H410 |
P273 P391 P501 |
If chronic toxicity data are used, then it is classified in Category 1 because it is non-rapidly degradable (a degradation rate by BOD: 1 % (the existing chemicals survey program, 2002)) and 21-day NOEC = 0.0051 mg/L for crustacea (Daphnia magna) (Ecotoxicity tests by Environment agency, 1998). If acute toxicity data are used for trophic levels for which chronic toxicity data are lacking, then it is classified in Category 3 because it is non-rapidly degradable (a degradation rate by BOD: 1 % (the existing chemicals survey program, 2002)) and 96-hour LC50 = 46 mg/L for fish (Oryzias latipes) (Ecotoxicity tests by Environment agency, 1998). It was classified in Category 1 by a comparison between the above results. |
