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	- -	-	-	There are five reports of LD50 values for rats of > 6,000 mg/kg (PATTY (6th, 2012), HSDB (Access on July 2016)), > 15,000 mg/kg (EU-RAR (2003), DFGOT (2015)), > 29,100 mg/kg (EU-RAR (2003), NICNAS (2015), DFGOT (2015), Evaluation of effects on food safety (Food Safety Commission, 2016)), > 62,080 mg/kg (EU-RAR (2003), NICNAS (2015), Evaluation of effects on food safety (Food Safety Commission, 2016)), 64,000 mg/kg (HSDB (Access on July 2016)). Based on these, it was classified as "Not classified."	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	There are reports of an LD50 value of > 2,910 mg/kg (EU-RAR (2003), NICNAS (2015), DFGOT (2015)) for rats, which corresponds to "Not classified." 　There are two reports of LD50 values of > 3,160 mg/kg (EU-RAR (2003), NICNAS (2015), DFGOT (2015)), and > 9,700 mg/kg (EU-RAR (2003), HSDB (Access on July 2016)) for rabbits, both of which correspond to "Not classified." 　Based on these, it was classified as "Not classified."	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	Based on a report of an LC50 value (4 hours) of > 12.54 mg/L (females and males) (EU-RAR (2003), NICNAS (2015), DFGOT (2015), Evaluation of effects on food safety (Food Safety Commission, 2016), HSDB (Access on July 2016)) for rats, it was classified as "Not classified." Besides, since this value is higher than the saturated vapor pressure concentration (12.7 ng/L), a reference value of mist was applied.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
2	Skin corrosion/irritation	Not classified	- -	-	-	In a skin irritation test (OECD TG 404) using rabbits, transient very slight irritation was observed. Moreover, in other rabbit skin irritation tests (4-hour application), skin irritation was transient and very slight (EU-RAR (2003), DFGOT (2015)). Also, in a human patch test, when applying 0.2 mL occlusively for 24 hours to 15 subjects, irritation was not observed in the examinations at 30 minutes and 24 hours after patch removal (EU-RAR (2003)). Based on these results, it was judged to be classified as "Not classified" (Category 3 in UN GHS classification).	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Not classified	- -	-	-	In an eye irritation test (OECD TG 405) using rabbits, conjunctival redness (score 2) was observed at 1 hour after application but was not observed after 24 hours (DFGOT (2015), EU-RAR (2003)). Also, in other eye irritation tests using rabbits, very slight conjunctival redness and swelling were observed transiently but disappeared within 48 hours and no effect on the cornea and iris was observed (DFGOT (2015), EU-RAR (2003), PATTY (6th, 2012)). Based on these results, eye irritation was judged to be extremely weak, and it was classified as "Not classified."	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Skin sensitization	Classification not possible	- -	-	-	In a skin sensitization test (modified Buehler test) using guinea pigs, erythema was observed in 15 out of 20 animals and edema was found in one animal, and it was judged as positive (DFGOT (2015), EU - RAR (2003)). On the other hand, in other skin sensitization tests (Buehler test and maximization test), both were negative (DFGOT (2015), EU-RAR (2003), PATTY (6th, 2012)). In addition, in humans, in patch tests on 104 volunteers, 310 patients with dermatosis, 144 patients with plastic or glue allergy, no positive reaction was observed in any cases (DFGOT (2015), EU-RAR (2003), PATTY (6th, 2012)). Because conflicting data were obtained, it was classified as "Classification not possible."	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	The substance 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, a micronucleus assay using mouse bone marrow cells is negative (EU-RAR (2003), NICNAS (2015), PATTY (6th, 2012)). As for in vitro, bacterial reverse mutation tests, and mouse lymphoma assays using cultured mammalian cells are negative (EU-RAR (2003), NICNAS (2015), PATTY (6th, 2012)).	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data. 　Besides, an increased incidence of mononuclear cell leukaemia (MNCL) was observed in a carcinogenicity study using rats given this substance by feedings for 2 years. However, MNCL is a common neoplasm in F344 rats, and it was judged as not relevant to humans. 　In addition, no increased incidence of tumor related to the administration was observed (NICNAS (2015), PATTY (6th, 2012)).	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	In two 2-generation reproductive toxicity studies using rats administered by the oral route (feeding), no effect on fertility was observed even at the doses where general toxic effects (reduction in body weight gain, increase in liver and kidney weight, etc.) were observed in F0 and F1 parental animals. However, in the F1 and F2 pups, there was an increase in the mortality rate up to postnatal day four (up to weaning at high doses), and in one test, in addition, delay in preputial separation was observed in F2 (NICNAS (2015), PATTY 6th, 2012)). 　On the other hand, as a result of gavage administration to pregnant rats during the organogenesis period, slight effects (skeletal variation such as supernumerary ribs etc.) were only observed in the fetus at the doses lower than the doses with general toxicity in maternal animals (NICNAS (2015) , PATTY (6th, 2012)). 　As above, the substance was classified in Category 2 for this hazard class since the postnatal mortality rate of the pups was increased at the dose where general toxicity in parental animals is manifested in two-generation studies using rats.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	There is no single exposure data on this substance in humans. 　As for experimental animals, in rats given this substance by oral administration at a dose exceeding the guidance value ranges of Category 2, there was no mortality or manifestation of symptoms, and no change in necropsy was observed (EU-RAR (2003)). 　Also, when rabbits were dermally administered at doses exceeding the guidance value range of Category 2, general symptoms such as anorexia etc., and dark reddening of the lungs at the necropsy were observed when applied on abraded skin, but when applied on healthy skin, only skin erythema as a local effect was observed, and systemic toxicity was not observed (EU-RAR (2003)). Also, in dermal administration at a dose exceeding the guidance value range of Category 2 to rats, no general symptoms and pathological abnormalities at necropsy were observed (EU-RAR (2003)). 　Furthermore, in an acute study using rats exposed by inhalation at doses exceeding the guidance value range of Category 2, it is only reported that symptoms after the exposure were agitation and unkempt appearance, and as the sole pathological finding at necropsy, numerous dark red foci in the lung were more frequently observed in the treated group (EU-RAR (2003)). 　From the above, since effects of this substance in animals studies were observed only when large amounts of this substance exceeding the guidance value range were administered, it is not possible to estimate the effects in humans. 　Therefore, because there is not sufficient data available for the judgement of category, it was classified as "Classification not possible" according to the GHS classification guidance for the Japanese government.	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	There is no information on humans. 　As for experimental animals, in a 13-week repeated dose toxicity study using dogs administered by feeding, hypertrophy and vacuolation of hepatocytes were observed at 75 mg/kg/day, which is within the range of Category 2 (EU-RAR (2003), NICNAS (2015), DFGOT (2015), Evaluation of effects on food safety (Food Safety Commission, 2016)). 　In several 21-day to 2-year repeated dose toxicity studies using rats administered by feeding, hypertrophy of hepatocytes and induction of drug-metabolizing enzymes, etc. in the liver have been reported at outside the range of Category 2 (EU-RAR (2003), NICNAS (2015), DFGOT (2015), Evaluation of effects on food safety (Food Safety Commission, 2016)). 　The changes in the liver seen in dogs are not regarded as serious toxicological findings since histological changes are slight, dose dependency is absent, and effects in liver enzymes such as ALT and AST are not observed, etc. (EU-RAR (2003)). 　As mentioned above, the effects on the liver was observed in the oral route, however, they are not serious changes and data on other routes are insufficient. Therefore, it was not classified as "Not classified" but "Classification not possible."	FY2016	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data. 　Besides, from numerical data (viscosity: 130 mPa*s (20 deg C), density (specific gravity): 0.97 (20 deg C)) listed in EU-RAR (2003), the kinematic viscosity is calculated to be 134 mm2/sec (20/20 deg C).
