4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
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 was reported to be negative in an Ames test (EHC 202 (1998), HSDB (2010)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	It was classified as "Classification not possible" because EPA classified it in D for carcinogenicity (IRIS (1997)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Category 1 (respiratory organs), Category 2 (liver, kidney)	Danger Warning	H372 H373	P260 P264 P270 P314 P501	In a 90-day repeated oral administration test with mice (doses: 100, 200, 400 mg/kg/day), increased liver weights in both males and females in the groups at or above 100 mg/kg/day, increased incidences and aggravation of hypertrophy and necrosis of the centrilobular hepatocytes in the liver in females at or above 100 mg/kg/day and males at or above 200 mg/kg/day, and nephrosis and related renal lesions in females at or above 100 mg/kg/day were observed (Environmental Risk Assessment for Chemical Substances vol. 7 (Ministry of the Environment, 2009)). From the above, it was classified in Category 2 (liver, kidney ) because adverse effects were found in the liver and kidney at 100 mg/kg/day corresponding to the upper limit of the guidance value range. On the other hand, in a 4-month repeated inhalation exposure test with rats (vapour: 4 hours/day, 0.5-1.25 mg/m3), findings such as bronchitis, peribronchitis with alveolar epithelial hyperplasia and bronchial epithelial metaplasia, and detachment of bronchial and alveolar epithelium are reported as lung effects in histological examination (Environmental Risk Assessment for Chemical Substances vol. 7 (Ministry of the Environment, 2009)). From the results, the test concentrations (converted 6-hour/day equivalent value: 0.0004-0.001 mg/L) correspond to the guidance values for Category 1, therefore it was classified in Category 1 (respiratory system).

10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）

ENVIRONMENTAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
11	Hazardous to the aquatic environment Short term (Acute)	Category 1	Warning	H400	P273 P391 P501	It was classified in Category 1 from 48-hour LC50 = 0.041 mg/L for crustacea (Daphnia magna) (EHC202, 1998).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
11	Hazardous to the aquatic environment Long term (Chronic)	Category 1	Warning	H410	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 32-day NOEC = 0.509 mg/L for fish (Pimephales promelas) (EHC202, 1998). 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 (not readily degradable, BOD 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law)), and 48-hour LC50 = 0.041 mg/L for crustacea (Daphnia magna) (EHC202, 1998). By drawing a comparison between the above results, it was classified in Category 1.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）

This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
