Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified |
- |
- | - | It was classified as "Not classified" in the Classification JIS (corresponding to Category 5 in UN GHS classification) based on an LD50 value of 3,700 mg/kg bw for rats (SIAP (2008)). |
1 | Acute toxicity (Dermal) | Not classified |
- |
- | - | It was classified as "Not classified" in the Classification JIS (corresponding to Category 5 in UN GHS classification or "Not classified") based on an LD50 value of > 3,170 mg/kg bw for rats (SIAP (2008)). |

Danger |

P304+P340
P403+P233 P260 P271 P284 P310 P320 P405 P501 |
It was classified in Category 2 based on a 4-hour exposure LC50 value of 0.5 mg/L for rats (SIAP (2008)). Besides, it was regarded as a test on dust because the LC50 value was higher than the saturated vapour pressure concentration (7.03E-09 mg/L). |
2 | Skin corrosion/irritation | Not classified |
- |
- | - | It was classified as "Not classified" because there was minimal irritation in a test by a 24-hour application to the rabbit skin (SIAP (2008)). |
3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 |
P305+P351+P338
P280 P310 |
It was classified in Category 1 because there was serious eye damage in a test by an application to the rabbit eye (SIAP (2008)). |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | No data available. |
4 | Skin sensitization | Not classified |
- |
- | - | It was classified as "Not classified" because it was concluded that it was not considered to possess skin sensitization properties based on the available information from two guinea pig tests (a maximization test and a photosensitization test) (SIAP (2008)). |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | The classification is not possible due to no in vivo test data. Besides, as for in vitro tests, it is reported that it was negative in both an Ames test and a chromosomal aberration test with human lymphocytes (OECD TG 473) (SIAP (2008)). |
6 | Carcinogenicity | Classification not possible |
- |
- | - | No data available. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | In a one-generation reproductive toxicity test by oral administration to rats (OECD TG 415), parent animals showed general toxicity such as decreased weight gain and food consumption in the high dose group (300 mg/kg/day), but there was no reproductive toxicity. And as for developmental toxicity, only slightly decreased pup weights during lactation were observed, and there were no other adverse effects (SIAP (2008)). However, due to no data on the investigation of fetuses at the end of gestation, data are insufficient on effects on the development of offspring. Therefore, it was classified as "Classification not possible." |
8 | Specific target organ toxicity - Single exposure | Category 1 (systemic toxicity) |
Danger |
H370 |
P308+P311
P260 P264 P270 P321 P405 P501 |
It is reported that signs of dyspnea, trismus, tremor, and sedation were observed in a dose-dependent intensity in all treated animals in an acute toxicity test with rats by 4-hour inhalation exposure (LC50 value: 0.5 mg/L) (SIAP (2008)). The above signs and deaths occurred within the guidance values for Category 1, but because it was hard to specify the target organ, it was classified in Category 1 (systemic toxicity). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | Findings reported in repeated dose toxicity tests with rats and dogs were limited to reduced weight gain and distentions of the small intestine in some animals on necropsy in a 28-day repeated oral administration toxicity test with rats (0, 50, 200, 600 mg/kg bw/day), reduced weight gain in a 90-day diet administration toxicity test with rats (males: 0, 26, 80 or 261 mg/kg bw/day, females: 0, 29, 90 or 277 mg/kg bw/day), and reduced weight gain and liver hypertrophy in a 28-day repeated oral administration toxicity test with dogs (males: 0, 27, 69 or 150 mg/kg bw/day, females: 0, 27, 78 or 155 mg/kg bw/day). Because no serious toxicity effects were observed, it was estimated to correspond to "Not classified" in the oral route. However, because effects are unknown in the other routes due to no data, it was classified as "Classification not possible" for this hazard class. |

It was classified in Category 2 from 72-hour ErC50 = 1.1 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1999)). |

If chronic toxicity data are used, then it is classified in Category 1 due to being not rapidly degradable (a 28-day degradation rate by OECD Test Guideline 301B: 10-24% (SIAP (Conclusions Agreed in SIAM 26, 2008))), and 72-hour NOEC = 0.050 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1999)). 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 (a 28-day degradation rate by OECD Test Guideline 301B: 10-24% (SIAP (Conclusions Agreed in SIAM 26, 2008))), and 96-hour LC50 = 4.3 mg/L for fish (Lepomis macrochirus, Oncorhynchus mykiss) (SIAP (Conclusions Agreed in SIAM 26, 2008)). By drawing a comparison between the above results, it was classified in Category 1. |
