2	Skin corrosion/irritation	Not classified	- -	-	-	It was classified as "Not classified" because it was not irritating in a test by a 4-hour semi-occlusive application of 0.5 mL of this substance to the rabbit skin (OECD TG 404) (BUA 161 (1997)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）

Because of the occurrence of clouding of the cornea and the reversibility by day 7, it was classified in Category 2B.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Respiratory 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.

FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	Data are lacking. Besides, ACGIH classified dimethylaniline in A3 for carcinogenicity as mixed isomers (ACGIH (2002)), corresponding to Category 2. And as for epidemiological surveys, it is reported that in a case-control study in 298 patients diagnosed with bladder cancer and 308 control subjects in California, the adduct of this substance and Hb was significantly increased in the patient group, and this substance and 2,6-DMA were considered to be one of the independent predictors of bladder cancer risk (Environmental Risk Assessment for Chemical Substances vol. 7 (Ministry of the Environment, 2009)).	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	Category 1 (blood)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	It is reported that in a single oral administration test with rats, a methemoglobin level reached a maximum of 32.7% after 3 hours in the 4.80 mmol/kg group (580 mg/kg), exceeded 5% in the groups at or above 1.2 mmol/kg (145 mg/kg) corresponding to the guidance values for Category 1 (4.96% in the control group), and this substance had a higher ability to form methemoglobin than the other isomers (Environmental Risk Assessment for Chemical Substances vol. 7 (Ministry of the Environment, 2009)). Therefore, it was classified in Category 1 (blood). Besides, in humans, it is described that exposure to this substance at high levels could cause lowering of consciousness and formation of methemoglobin, inhalation may cause dizziness, drowsiness, headache, and nausea, and ingestion may cause cyanosis of lips, nails, and skin, dizziness, drowsiness, headache, nausea, and unconsciousness (Environmental Risk Assessment for Chemical Substances vol. 7 (Ministry of the Environment, 2009)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Category 2 (blood)	Warning	H373	P260 P314 P501	In a 28-day repeated oral administration toxicity test with rats (doses, 0, 10, 60, 360 mg/kg: GLP-compliant), an increase in methemoglobin, decreases in erythrocyte counts, hemoglobin level, and hematocrit values, and increases in reticulocyte rate and spleen weights were observed in the groups at or above 60 mg/kg. And histopathological examination revealed hemosiderin deposits in the liver and spleen, extramedullary hematopoiesis of the spleen, hypertrophy of hepatocytes in the liver, and hypertrophy of follicular epithelium of the thyroid at the same doses. From the above, because it is reported that primary changes were an increase in methemoglobin accompanied by anemia in both males and females at or above 60 mg/kg (converted guidance value; 18.6 mg/kg) corresponding to the guidance values for Category 2 (JECDB (Access on July 2012)), it was classified in Category 2 (blood).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	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 48-hour EC50 = 2.2 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1997); Environmental Risk Assessment for Chemical Substances Vol. 7 (Ministry of the Environment, 2009)).	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 1 due to being not rapidly degradable (not readily degradable, BOD 3% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1990)), and 21-day NOEC = 0.03 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1997)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 3 due to being not rapidly degradable (not readily degradable, BOD 3% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1990)), and 96-hour LC50 = 33.9 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, 2000)). 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）
