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)	Category 4	Warning	H302	P301+P312 P264 P270 P330 P501	On the basis of LD50 values of 630 mg/kg [GLP compliance] and 1470 mg/kg [OECD TG 401] for rats (both SIDS (2011)), it was classified in Category 4.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	From an LD50 value of >2010 mg/kg for rabbits [GLP compliance] (SIDS (2011)), it was classified as "Not classified" in JIS classification (Category 5 in UN GHS classification).	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)	Category 2	Danger	H330	P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501	From LC50 values of 232 to 334 ppm in 4-hour exposure to rats [OECD TG 403; GLP compliance] (SIDS (2011)), it was classified in Category 2. Besides, a reference value of gasses as vapour with hardly included mist was applied because the test concentrations (232 to 334 ppm) are lower than 90 % of the saturated vapour pressure concentration (42632 ppm).	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	Category 1	Danger	H314	P301+P330+P331 P303+P361+P353 P305+P351+P338 P304+P340 P260 P264 P280 P310 P321 P363 P405 P501	In a test semi-occlusive applied 0.5 mL of undiluted this substance to six rabbit skins for 4 hours (GLP compliance), erythema and edema were observed until 21 days after application, a maximum irritation score was 7.0/8.0, necrosis was present on the application sites in all six animals, and this substance was assessed as corrosive. (SIDS (2011)) Therefore it was classified in Category 1.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
3	Serious eye damage/eye irritation	Category 2A	Warning	H319	P305+P351+P338 P337+P313 P264 P280	In a test dropped 0.1 mL of undiluted this substance to the conjunctival sac of rabbits, it was assessed as moderately irritating from a maximum average irritation score (equivalent to AOI) of 39.8/110 after 24 hours. (SIDS (2011)) Another test applied 0.05 mL of undiluted this substance to the conjunctival sac of rabbits concluded that the eyes are at risk of severe damage due to marked eye reactions with corneal opacity lasting until the end of an 8-day observation period despite subsided erythema and chemosis. (SIDS (2011)) From the above, it was classified in Category 2A.	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	- -	-	-	The classification is not possible due to no in vivo test data. Besides, an Ames test reported a weakly positive as an in vitro test (SIDS (2011)).	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	- -	-	-	No data.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
8	Specific target organ toxicity - Single exposure	Category 1 (respiratory organs), Category 2 (nervous system)	Danger Warning	H370 H371	P308+P311 P260 P264 P270 P321 P405 P501	In an acute oral toxicity test in rats (500 to 800 mg/kg), an LD50 value of 638 mg/kg and toxicological symptoms such as decreased activity, ataxia, body tremors, constricted pupils, dilated pupils, and ptosis were observed. (SIDS (2011)) And in another acute oral toxicity test in rats (316 to 3160 mg/kg) (OECD TG 401), an LD50 value of 1470 mg/kg, apathy, abnormal agitation, and unsteady gait at 1000 mg/kg, and abnormal positioning, atony, a narcosis-like state with reduced pain and eye reflexes at 1470 mg/kg or higher were observed. (SIDS (2011)) Because above symptoms were observed at doses corresponding to Category 2 in Guidance values, it was classified in Category 2 (nervous system). On the other hand, in a 4-hour inhalation test exposed 1.144 or 1.647 mg/L (vapour) to rats (OECD TG 403; GLP), respiratory distress was observed. And increased weights and inflation of the lungs, and red or dark trachea with white frothy fluid were observed in necropsy in a 1.647 mg/L group where all animal died (SIDS (2011)). Furthermore, epistaxis, gasping, nasal discharge, and respiratory gurgle were observed by an inhalation exposure of 1.14 to 5.15 mg/L/1h (0.57 to 2.58 mg/L/4h) (vapour) to rats. And survived animals showed pale lung and lung edema at 0.74 mg/L/4h and red mottled lung at 1.38 mg/L/4h in the necropsy. (SIDS (2011)) From the above, it was classified in Category 1 (respiratory system) because effects on lung and upper respiratory tract were observed within a range of Category 1 in Guidance values.	FY2011	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	No data. Besides, according to a report on a 28-day oral administration test given pivalic acid (a hydrolysate of this substance) to rats (OECD TG 407; GLP), only clinical signs were shaking of the head and sneezing with nasal discharge at 100 and 300 mg/kg/day considered to be caused by irritant effects, some slight changes in a biochemical examination and no pathological effect were observed, and acute toxicity is low.
