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	- -	-	-	[Rationale for the Classification] Based on (1)-(3), it was classified as "Not classified." [Evidence Data] (1) LD50 for rats: >2,000 mg/kg, >4,400 mg/kg, >=5,000 mg/kg (ACGIH (7th, 2019)) (2) LD50 for rats: 4,500 mg/kg (ECETOC TR95 (2005)) (3) LD50 for rats: >5,000 mg/kg (PATTY (6th, 2012))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	[Rationale for the Classification] Based on (1), it was classified as "Not classified." [Evidence Data] (1) LD50 for rabbits: 8,100 mg/kg (ACGIH (7th, 2019), PATTY (6th, 2012), ECETOC TR95 (2005))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	[Rationale for the Classification] Liquid (GHS definition). It was classified as "Not classified (Not applicable)."	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1), since there were no deaths by exposure to this substance, the LC50 was considered to be higher than 2,213 ppm, but the category could not be determined. Therefore, it was classified as "Classification not possible." Besides, the exposure concentrations were lower than 90% of the saturated vapor pressure concentration (5,079.3 ppm), so the reference values in units of ppm were applied as vapour with little mist. [Evidence Data] (1) Inhalation in rats (4 hours): no mortality at 3,337 ppm (whole-body exposure), 2,213 ppm (nose-only exposure) (ACGIH (7th, 2019), PATTY (6th, 2012))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	[Rationale for the Classification] Based on (1), it was classified as "Not classified." Besides, since the exposure concentration was higher than 90% of the saturated vapor pressure concentration (5,079.3 ppm), a reference value in unit of mg/L was applied as a mist. [Evidence Data] (1) Inhalation in rats (4 hours): no mortality at 1,420 mg/L (ACGIH (7th, 2019))	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
2	Skin corrosion/irritation	Not classified	- -	-	-	[Rationale for the Classification] Based on (1), it was classified as "Not classified." [Evidence Data] (1) In a skin irritation test with rabbits equivalent or similar to OECD TG 404, slight erythema was observed at 1 and 24 hours after exposure and disappeared after 48 hours. Flaking was also noted, but it disappeared within 7 days. The mean scores for erythema and edema at 24/48/72 hours were 0-1.33 and 0, respectively (REACH registration dossier (Access on August, 2019)). [Reference Data, etc.] (2) This substance was slightly irritating to the skin of rabbits, producing minimal transient reddening and edema with slight flaking of the skin after 72 hours (ACGIH (7th, 2019)). (3) Moderate irritation was observed in skin irritation tests by 24-hour occlusive or 4-hour semi-occlusive application to rabbits (ECETOC TR64 (1995)). (4) This substance is slightly irritating to the skin (PATTY (6th, 2012)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Category 2B	- Warning	H320	P305+P351+P338 P337+P313 P264	[Rationale for the Classification] Based on (1) and (2), it was classified in Category 2B. [Evidence Data] (1) In an eye irritation test with rabbits, no severe irritation was shown and the effects were fully reversible within 7 days (ECETOC TR64 (1995), PATTY (6th, 2012)). (2) Results of eye irritation tests with rabbits ranged from non-irritating to moderately irritating (ACGIH (7th, 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Respiratory sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Skin sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) A skin sensitization test with guinea pigs (maximization method) on the acetate of this substance (CAS RN 54839-24-6) was negative, suggesting that the parent compound, this substance, would also be unlikely to possess skin sensitizing potential (ECETOC TR64 (1995), ACGIH (7th, 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	[Rationale for the Classification] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, there were reports of it being negative in a bacterial reverse mutation test and a chromosomal aberration test with human lymphocytes (ECETOC TR95 (2005)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1), as for developmental toxicity, no effects on embryos/fetuses were observed even at doses where maternal toxicity was observed. However, since there were no data on parental sexual function and fertility, it was classified as "Classification not possible" due to lack of data. [Evidence Data] (1) In tests in which female rats and rabbits were exposed by inhalation to the vapor of this substance during gestation, reduced body weight gain and decreased food consumption were observed in maternal animals, but no effects on fetal development were observed (ECETOC TR95 (2005), PATTY (6th, 2012), ACGIH (7th, 2019)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Category 3 (narcotic effects, respiratory tract irritation)	Warning	H336 H335	P304+P340 P403+P233 P261 P271 P312 P405 P501	[Rationale for the Classification] Based on (1) and (2), it was classified in Category 3 (narcotic effects, respiratory tract irritation). [Evidence Data] (1) In a 4-hour single inhalation exposure test with rats, at 10,000 ppm (42.5 mg/L, exceeding the range of Category 2), irritation of the eyes and nose and central nervous system depression were observed, but no mortality was reported (ACGIH (7th, 2019), PATTY (6th, 2012), ECETOC TR95 (2005)). (2) In another 4-hour single inhalation exposure test with rats, transient lachrymation, salivation, and central nervous system depression were observed at 2,213 ppm (9.59 mg/L, equivalent to Category 1), but no mortality was observed (ACGIH (7th, 2019), PATTY (6th, 2012), ECETOC TR95 (2005)).	FY2019	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1), it is considered to correspond to "Not classified" in the inhalation route. The classification was not possible due to lack of data in the oral and dermal route. [Evidence Data] (1) In a 13-week inhalation exposure test with rats (6 hours/day, 5 days/week), increased urine volume was observed at or above 300 ppm (converted guidance value: 0.9 mg/L, within the range of Category 2), reversible eye and nose irritation, sedation and increased liver weights, and focal macrophage aggregation in the lungs were observed at 2,000 ppm (converted guidance value: 6.2 mg/L, exceeding Category 2) (ACGIH (7th, 2019), PATTY (6th, 2012), ECETOC TR95 (2005)). [Reference Data, etc.] (2) When rats were administered orally at 2 mL/kg 10 times, slightly reduced body weight gain and minor hematological changes in males, and increased liver weight in males and females were observed (ECETOC TR95 (2005)).
