HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Acute toxicity (Oral)	Category 4	Warning	H302	P301+P312 P264 P270 P330 P501	There are data from two tests with rats, an LD50 value in one test was 800 mg/kg (IUCLID (2000)) corresponding to Category 4, and an LD50 value in the other was 3,094 mg/kg (a combined value of 3,000 mg/kg for males and 3,217 mg/kg for females) (IUCLID (2000)) corresponding to "Not classified" in the Classification JIS. The category with higher hazard was adopted from a safety point of view, and it was classified in Category 4.
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available.
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	- -	-	-	No data available.
2	Skin corrosion/irritation	Not classified	- -	-	-	It was classified as "Not classified" because it was not irritating in a test by a 4-hour occlusive application 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 because it was slightly irritating in a test by an application to the rabbit eye (OECD TG405, GLP) (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 maximization test with guinea pigs (Directive 84/449/EEC, B.6. GLP) (IUCLID (2000)), but it is List 2 data, and the number of animals and a positive rate (a rate of sensitized animals) are unknown. Therefore, it was classified as "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, negative results are reported in both an Ames test (GLP) and a chromosomal aberration test with Chinese hamster V79 cells (OECD TG473, GLP) (IUCLID (2000)).
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.
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	Classification not possible	- -	-	-	Data are lacking. Besides, after 11-day diet administration to rats, there is a report on reduced weight gain, decreased food consumption, and liver effects (changes in biochemical values, increased liver weights, vacuolization of hepatocytes) in the high dose group (1%; converted guidance value 85.6 mg/kg/day) (IUCLID (2000)), but it is reported that in the high dose group (200 mg/kg/day; converted guidance value 62.2 mg/kg/day) after 28-day oral administration to rats, liver weights increased, however, there were no findings suggestive of hepatic lesions at clinical and histopathological examination (IUCLID (2000)), and the above was insufficient for the rationale 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)	Not classified	- -	-	-	It was classified as "Not classified" from 96-hour LC50 > 100 mg/L for fish (Danio rerio) (IUCLID, 2000, BUA 213, 1992).
11	Hazardous to the aquatic environment (Long-term)	Not classified	- -	-	-	Reliable chronic toxicity data were not obtained. It was classified as "Not classified" because it is not water-insoluble (water solubility = 5500 mg/L, NITE (2012)), and it was classified as "Not classified" in acute toxicity.
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.
