HEALTH 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
1	Acute toxicity (Oral)	Not classified	- -	-	-	Based on a LD50 value of >2000 mg/kg for rats ("Toxicity Testing Reports of Environmental Chemicals" (Chemicals Investigation Promoting Council) (access in Sep. 2009)), the substance was classified into "Not classified" in JIS Classification (correspond to Category 5 or "Not classified" in GHS classification).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	Based on a result of "moderate irritation and slight necrosis" by application of undiluted substance to rabbits (PATTY (5th, 2001)), the substance was classified into Category 2. As relevant information, there is a report of skin injury from contact as human health effects (HSDB (2003)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Diethylbenzene tested by drop on a rabbit eye caused transient symptoms of irritation, but no injury was detected by fluorescein staining (HSDB (2003)). Additionally, it was reported that men exposed to 1000 ppm experienced eye irritation which rapidly diminished in intensity on continued exposure and a concentration of 2000 ppm caused immediately severe eye irritation, lacrimation (HSDB (2003)), and there is a report that diethylbenzene is an eye irritant (HSDB (2003)). Based on these information, the substance was classified into Category 2. [Data for diethylbenzene was used as the basis of classification on the assumption that there are only minor differences between isomers.]	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data from in vivo mutagenicity tests. From in vitro mutagenicity tests, there are reports of a negative Ames test ("Toxicity Testing Reports of Environmental Chemicals" (Chemicals Investigation Promoting Council) (access on Sep. 2009)) and a negative Chinese hamster CHL cell chromosomal aberration test ("Toxicity Testing Reports of Environmental Chemicals" (Chemicals Investigation Promoting Council) (access on Sep. 2009)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Classification not possible	- -	-	-	In a combined repeat dose and reproductive/developmental toxicity test with rats (OECD TG422), there were no effects on mating, fertility and oestrus cycle and all gestation animals delivered pups normally ("Toxicity Testing Reports of Environmental Chemicals" (Chemicals Investigation Promoting Council) (access on Sep. 2009)). Although there was no adverse effect on sexual function and fertility of parental animals, classification was not possible due to lack of sufficient data for fetal development including teratogenicity.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	In a rat acute oral toxicity test (OECD TG401 (GLP)), decrease of spontaneous motor activity and lacrimation were observed at a dose level of 2000 mg/kg but no changes in body weight or treatment-related gross pathological changes were observed ("Toxicity Testing Reports of Environmental Chemicals" (Chemicals Investigation Promoting Council) (access on Sep. 2009)). Based on this result, the substance corresponds to "Not classified" with oral exposure. However, classification was not possible due to lack of data with other exposure routes (inhalation, dermal).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	In a combined repeat dose and reproductive/developmental toxicity test with rats (OECD TG422 (GLP)), increases in BUN and GPT were observed at 150 mg/kg/day (90-day equivalence: 75 mg/kg/day) and 750 mg/kg/day (90-day equivalence: 375 mg/kg/day), and increases in total protein, albumin, creatinine and total bilirubin were observed at 750 mg/kg/day. As the gross findings, increases in incidence of brown colored livers or enlargement of the livers were observed in male rats receiving 750 mg/kg/day, and swelling of centrilobular hepatocytes was observed histopathologically. Although morphological changes in the liver were observed at a high dose level (90-day equivalence: 375 mg/kg/day) which exceeds the guidance value range, some biochemical changes such as increased enzyme activity were observed at a middle dose level (90-day equivalence: 75 mg/kg/day) which is within the guidance value range. Therefore, classification was not possible due to lack of data for evidence of effects at the upper limit (100 mg/kg/day) of the guidance value range. The above information come from "Toxicity Testing Reports of Environmental Chemicals" (Chemicals Investigation Promoting Council) (access on Sep. 2009). For health hazards, refer also to the information of 1,2-diethylbenzene (CAS 135-01-3).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
10	Aspiration hazard	Classification not possible	- -	-	-	Although the substance is a hydrocarbon, classification was not possible since the kinematic viscosity at 40 degC was unknown.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
