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	- -	-	-	It was classified as "Not classified" (Category 5 in UN GHS classification) because it is described in SIDS (2002) that an LD50 value was < 5,000 mg/kg for rats (OECD TG 401), but from > 1,000 mg/kg of a preliminary test result, an LD50 value was estimated to be > 2,000 mg/kg.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	It was classified as "Not classified" based on a report on an LD50 value of > 3,200 mg/kg for rabbits (OECD TG 402) (SIDS (2002)). Besides, no death was observed after the application of 3,200 mg/kg (SIDS (2002)).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Vapours)	Not classified	- -	-	-	It was classified as "Not classified" based on a report on an LC50 value (4 hours) of > 20,917 ppm (= 58.2 mg/L) for rats (OECD TG 403) (SIDS (2002)). Besides, because the test concentration (20,917 ppm) was lower than 90% of the saturated vapour pressure concentration (526,159 ppm), a reference value in the unit of ppm was applied as a vapour without mist.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
2	Skin corrosion/irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, it is described in SIDS (2002) that moderate irritation was observed in an acute dermal toxicity test in which 3,200 mg/kg was applied to rabbits for 24 hours, but it was not adopted because of using a high application amount and long application time.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, it is described in SIDS (2002) that this substance is not expected to be a severe eye irritant from data on related compounds.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Skin sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	It was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. As for in vivo, it was negative in micronucleus tests with bone marrow cells of mice and rats (SIDS (2002)), and as for in vitro, it was negative in a bacterial reverse mutation test, a mouse lymphoma test and a chromosomal aberration test with cultured mammalian cells (SIDS (2002), IUCLID (2000)).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
6	Carcinogenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, isoprene, the isomer, was not carcinogenic at doses up to 7,000 ppm in an inhalation administration test with rats (SIDS (2002)).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
7	Reproductive toxicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. Besides, it is reported in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with rats (OECD TG 422), no evidence of reproductive toxicity in parent animals was found, and there were almost no exposure effects on the development of offspring (SIDS (2002), IUCLID (2000)). However, because the test is a screening test, and there was no sufficient information on developmental toxicity, it was classified as "Classification not possible."	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Category 3 (Respiratory tract irritation)	Warning	H335	P304+P340 P403+P233 P261 P271 P312 P405 P501	It was classified in Category 3 (respiratory tract irritation) because it is described that it is irritating to the respiratory tract in humans, and the threshold level causing hypoxia was 850-1,000 mg/m3 for this substance (IUCLID (2000)).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	It is described that in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with rats, no toxicity effects were observed even after the oral administration of a limit dose (1,000 mg/kg/day) (SIDS (2002)), therefore it corresponds to "Not classified" in the oral route. However, because of no toxicity information on the other routes, the classification is not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))

11	Hazardous to the aquatic environment Long term (Chronic)	Not classified	- -	-	-	Reliable chronic toxicity data were not obtained. It was classified as "Not classified" because it is not water-insoluble (water solubility = 0.069 g/100 mL, ICSC, 2008), and it was classified as "Not classified" in acute toxicity.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
