HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Acute toxicity (Oral)	Not classified	- -	-	-	Both an LD50 value of 5 g/kg for mice (NTP TR 494 (2005)) and an LD50 value of > 5,000 mg/kg for rats from List 2 information (IUCLID (2000)) correspond to "Not classified."
1	Acute toxicity (Dermal)	Not classified	- -	-	-	It was classified as "Not classified" based on an LD50 value of > 5,000 mg/kg for rats (IUCLID (2000)) and an LD50 value of > 3,000 mg/kg for rabbits (IUCLID (2000)).
1	Acute toxicity (Inhalation: Gases)	Not applicable	- -	-	-	Solid (GHS definition)
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	An LC50 value by 4-hour exposure of > 1.327 mg/L for rats (IUCLID (2000)) corresponds to Category 4 or "Not classified," but the category cannot be determined. Therefore, it was classified as "Classification not possible." Besides, because the test concentration was higher than the saturated vapour pressure concentration, it was regarded as a test on dust.
2	Skin corrosion/irritation	Not classified	- -	-	-	It was classified as "Not classified" because it was not irritating in a skin irritation test with rabbits (OECD TG 404) (IUCLID (2000)). Besides, it is also reported that it was not irritating in another test by a 24-hour semi-occlusive application of 500 microL or 0.5 g to the rabbit skin (IUCLID (2000)).
3	Serious eye damage/eye irritation	Category 2B	- Warning	H320	P305+P351+P338 P337+P313 P264	It was classified in Category 2B based on the result that it was slightly irritating in an eye irritation test with rabbits (OECD TG 405) (IUCLID (2000)). Besides, it was not irritating in another test in which 100 microL or 0.1 g was applied to the rabbit eye (IUCLID (2000)).
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.
4	Skin sensitization	Classification not possible	- -	-	-	It is reported that it was not sensitizing in a skin sensitization test with guinea pigs (Intracutaneus Test), which gave a negative result (IUCLID (2000)). However, because it was from List 2 information, and the test method was not the one approved by OECD, it was classified as "Classification not possible."
5	Germ cell mutagenicity	Not classified	- -	-	-	It was classified as "Not classified" based on negative results in micronucleus tests with bone marrow cells after oral or intraperitoneal administration to mice (in vivo somatic cell mutagenicity test) (NTP DB (Access on July 2012), IARC 101 (2012)). Besides, a positive result was obtained in a micronucleus test with peripheral blood after 14-week diet administration to mice (in vivo somatic cell mutagenicity test), but it is described that it may be due to increased erythropoiesis (NTP TR 494 (2005)). And as for in vitro tests, it is reported that it was negative or positive in Ames tests (NTP DB Study ID A40147 (2006)), positive in a micronucleus test with hamster embryo cells, negative in a chromosomal aberration test with CHO cells, and negative in a gene mutation test with L5178Y mouse lymphoma cells (IARC 101 (2012)).
6	Carcinogenicity	Category 2	Warning	H351	P308+P313 P201 P202 P280 P405 P501	It was classified in Category 2 because IARC classified it in Group 2B for carcinogenicity (IARC 101 (2012)). Besides, it is reported that in 2-year diet administration tests with rats and mice, there was some evidence of carcinogenicity in male rats based on increased incidences of renal tubule adenoma and transitional epithelial papilloma in the kidney and urinary bladder, and there was clear evidence of carcinogenicity in female rats based on increased incidences of renal tubule neoplasms (NTP TR 494 (2005)). On the other hand, it is reported that increased incidences of liver neoplasms were observed in both male and female mice, and there was clear evidence of carcinogenicity (NTP TR 494 (2005)).
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	No data available.
9	Specific target organ toxicity - Repeated exposure	Category 2 (blood, lung)	Warning	H373	P260 P314 P501	It was classified in Category 2 (blood, lung) because there is a report on changes in hematological profile (decreased hemoglobin level, decreased erythrocytes, decreased reticulocytes) and histopathological findings in the lung (emphysema, atelectasis, cellular proliferation, perivascular hyperemia, and exudates in the alveolar lumen) at 0.0122 mg/L in a 4-month inhalation exposure test (5-6 hours/day) with rats (IUCLID (2000)). Besides, it corresponds to Category 1 judging from the guidance values, but it is List 2 data, and its test does not meet Decision criteria 1b3), so it was classified in Category 2 according to the GHS classification guidance for the Japanese government. On the other hand, as for the oral route, there is a report on responsive anemia, hematopoietic cell proliferation, liver hypertrophy, centrilobular hypertrophy of hepatocytes, nephropathy, etc. in 14-week diet administration tests with rats and mice (NTP TR 494 (2005)), but these were found at the high doses above the guidance value range, and the NOEL is unknown. In the oral route, there is also a report on decreased erythrocytes, centrilobular hypertrophy of hepatocytes, etc. in a 3-month diet administration test with rats and a 28-day oral administration test with rats (IUCLID (2000)), but the details are unknown, and these could not be used for classification.
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.

ENVIRONMENTAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
11	Hazardous to the aquatic environment (Acute)	Category 1	Warning	H400	P273 P391 P501	It was classified in Category 1 from 48-hour LC50 = 0.0942 mg/L for crustacea (Americamysis bahia) (Environmental Risk Assessment for Chemical Substances Vol. 1 (Ministry of the Environment, 2002)).
11	Hazardous to the aquatic environment (Long-term)	Category 1	Warning	H410	P273 P391 P501	If chronic toxicity data are used, then it is classified in Category 1 due to being not rapidly degradable (readily biodegradable, BOD: 52.3% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1975)), and 8-day NOEC < 0.01 mg/L for aquatic plants (Lemna gibba) (Environmental Risk Assessment for Chemical Substances Vol. 1 (Ministry of the Environment, 2002)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 1 due to being not rapidly degradable (readily biodegradable, BOD: 52.3% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1975)), and 48-hour LC50 = 0.0942 mg/L for crustacea (Americamysis bahia) (Environmental Risk Assessment for Chemical Substances Vol. 1 (Ministry of the Environment, 2002)). From the above results, it was classified in Category 1.
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.
