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	- -	-	-	From no mortality at a dose of 2000 mg/kg and an LD50 value of > 2000 mg/kg for rats (Report on Toxicity Tests of Chemical Substances, MHLW (2007)), it was classified as "Not classified."	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	"Liquids" according to GHS definition.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Lack of data. Besides, an LC50 value of 40 mg/L/2h (30 mg/L/4h) in 2-hour exposure for rats (RTECS (2006)) is from List 3, and the details are unknown. The test condition is considered to be a vapour including mist because the LC50 value （40 mg/L） is not less than 90 % of the saturated vapour pressure concentration (43 mg/L).	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
2	Skin corrosion/irritation	Classification not possible	- -	-	-	No data. Besides, there is a description of cyclohexane that is "mildly irritating to human skin" (HSDB (2002)).	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Skin sensitization	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Due to no in vivo test data, the classification is not possible. Besides, both an Ames test and a chromosomal aberration test with Chinese hamster lung cells reported negative results as in vitro tests (Report on Toxicity Tests of Chemical Substances, MHLW (2006)).	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
7	Reproductive toxicity	Classification not possible	- -	-	-	A combined repeated dose toxicity study with reproduction/developmental toxicity screening test by oral administration to rats reported salivation and a decreased weight gain in parent animals as general toxicities at a high dose, but no changes in parameters such as sexual function, fertility, and survival and external surface of offspring, and no finding of evidence of reproduction toxicity related to this substance. (Report on Toxicity Tests of Chemical Substances, MHLW (2007)) However, due to lack of data, it was classified as "Classification not possible" in adverse effects on the development of the offspring including teratogenicity on fetal examination at term pregnancy.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	An oral administration test to rats given 300 or 2000 mg/kg reported no mortality and no abnormalities in clinical signs and in necropsy except a decreased weight gain at 2000 mg/kg. (Report on Toxicity Tests of Chemical Substances, MHLW (2007)) But a blood biochemical test and a histological test were not conducted, therefore, due to lack of data it was classified as "Classification not possible."	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	A combined repeated dose toxicity study with reproduction/developmental toxicity screening test by oral administration to rats reported hyperplasia in bladder mucosal epithelium at doses of 60 mg/kg/day (converted to a 90-day equivalent value: 28 mg/kg/day) or higher, and salivation and a decreased weight gain, and histopathological signs such as increased hyaline droplet disposition in proximal tubular epithelium in kidney in males, hyperplasia in bladder mucosal epithelium in females, as well as an increased number of reticulocyte, decreased inorganic phosphorus, and increased kidney weight in males or females at a dose of 300 mg/kg/day respectively (converted to a 90-day equivalent value: 140 mg/kg/day). (Report on Toxicity Tests of Chemical Substances, MHLW (2007)) Out of the above results, the hyperplasia in bladder mucosal epithelium found in males at the dose of 60 mg/kg/day was not used as a basis for classification because they are all minimal and details are unknown, therefore, it was classified as "Classification not possible." Besides, all of the other effects were found in doses above the upper limit (100 mg/kg/day) of Guidance values.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
10	Aspiration hazard	Classification not possible	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）

11	Hazardous to the aquatic environment Short term (Acute)	Category 2	- -	H401	P273 P501	On the basis of 48-hour EC50 = 4.018 mg/L for crustacea (Daphnia pulex) (AQUIRE, 2012), it was classified in Category 2.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
11	Hazardous to the aquatic environment Long term (Chronic)	Category 2	-	H411	P273 P391 P501	Reliable chronic toxicity data were not obtained. Due to lack of rapid degradability (hardly degradable, a degradation rate by BOD: 0 % (the existing chemicals survey program, 1977)) and acute toxicity Category 2, it was classified in Category 2.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in Annexes to the Montreal Protocol.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
