In a test by a 4-hour semi-occlusive application of 0.5 mL of the undiluted solution of this substance liquefied by heating to the rabbit skin (GLP-compliant), all six animals showed necrosis, PII (primary irritation index) was 7.25, and it was concluded to be corrosive (HPVIS (2009)). Therefore, it was classified in Category 1. | FY2012 | GHS Classification Guidance by the Japanese Government (July, 2010) |
3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 | P305+P351+P338 P280 P310 |
There are no data, but because it is corrosive to the skin (Category 1), it was classified in Category 1. | FY2012 | GHS Classification Guidance by the Japanese Government (July, 2010) |
4 | Respiratory sensitization | Classification not possible |

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, there is a report on a negative result in both an Ames test and a chromosomal aberration test with cultured Chinese hamster cells (JECDB (Access on Aug. 2012)). | FY2012 | GHS Classification Guidance by the Japanese Government (July, 2010) |

8 | Specific target organ toxicity - Single exposure | Category 2 (systemic) |
Warning |
H371 | P308+P311 P260 P264 P270 P405 P501 |
Lethargy, bloody eye discharge, bloody nasal discharge, labored breathing, tachypnea, anorexia, decreased body weights, hunchback position, muscle twitching, and calm were observed in an acute oral toxicity test with rats (dose range: 1,000-3,000 mg/kg). The dead animals showed hemorrhage in the gastrointestinal tract, liver, and lung, distention of the stomach, and discoloration of the liver and kidney (HPVIS (2009)), and an LD50 value was 1,650 mg/kg/bw. Because the target organ could not be specified, it was classified in Category 2 (systemic toxicity). | FY2012 | GHS Classification Guidance by the Japanese Government (July, 2010) |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (kidney) |
Warning |
H373 | P260 P314 P501 |
It was classified in Category 2 (kidney) because papillary necrosis of the kidney was observed at or above 300 mg/kg/day (converted guidance value: 93.3 mg/kg/day) corresponding to the guidance values for Category 2 at histological examination at the end of a treatment period in a 28-day repeated oral administration test with rats (Toxicity Test Guidelines specified by the Chemical Substances Control Law, GLP) (JECDB (Access on Aug. 2012)). In the test, hyperplasia of the mucosal epithelium in the forestomach in all males and females, and papillary necrosis of the kidney in three females and two males were found in the 1,000 mg/kg/day group (converted guidance value: 311 mg/kg/day), and there is a report on papillary necrosis of the kidney and hyperplasia of the mucosal epithelium in the forestomach in one male in the 300 mg/kg/day group. And effects on the upper gastrointestinal tract (including the stomach) and kidney were also seen at higher doses (500 mg/kg/day or above) in another test by diet administration to rats for 6-24 months (HPVIS (2009)). Besides, because this substance is corrosive to the skin, effects on the stomach were judged as local effects and were not adopted for classification. | FY2012 | GHS Classification Guidance by the Japanese Government (July, 2010) |

11 | Hazardous to the aquatic environment Short term (Acute) | Category 2 |
- |
H401 | P273 P501 |
It was classified in Category 2 from 96-hour LC50 = 2.6 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)). | FY2012 | GHS Classification Guidance by the Japanese Government (July, 2010) |
11 | Hazardous to the aquatic environment Long term (Chronic) | Category 2 |
- |
H411 | P273 P391 P501 |
If chronic toxicity data are used, then it is classified in Category 2 due to being not rapidly degradable (not readily degradable, BOD 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law)), and 72-hour NOEC = 0.44 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, BOD 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1980)), and 96-hour LC50 = 2.6 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. |
