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" because it is reported that there were no dead animals after administration of 2,000 mg/kg to rats (OECD Test Guideline 401; GLP-compliant), and an LD50 value was 2,000 mg/kg or above (JECDB (Access on July 2012)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	It is reported that there were no deaths after 1-hour exposure to 10.7 mg/L in rats, and an LC50 value was > 10.7 mg/L/1 hour (converted 4-hour equivalent value: 2.675 mg/L/4 hours) (IUCLID (2000)). The result corresponds to Category 4 or "Not classified," but the category cannot be determined. Therefore, it was classified as "Classification not possible." Besides, it is described that the substance was in a dust state (IUCLID (2000)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
2	Skin corrosion/irritation	Not classified	- -	-	-	It was classified as "Not classified" in the Classification JIS (corresponding to Category 3 in UN GHS classification) because it was slightly irritating in a test by a 24-hour occlusive application of 500 mg to the rabbit skin (IUCLID (2000)).	FY2012	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	Three tests with rabbits are described, and it is reported that it was moderately irritating, irritating, or not irritating (IUCLID (2000)). It was classified in Category 2A based on the results of being moderately irritating or irritating, corresponding to a more hazardous category. Besides, there is the information that a 2 g/L concentration (20 deg C) of this substance has pH 2-2.5 (IUCLID (2000)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
5	Germ cell mutagenicity	Not classified	- -	-	-	It was classified as "Not classified" based on a negative result in a micronucleus test by oral administration to mice (in vivo mutagenicity test) (IUCLID (2000)). Besides, as for in vitro tests, it is reported that it was negative in an Ames test (JECDB (Access on July 2012)), and a chromosomal aberration test with cultured Chinese hamster cells (CHL) gave a positive result, although the effects of a decrease in pH were suggested (JECDB (Access on July 2012)).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	In a test by oral administration of 2,000 mg/kg to rats, transient diarrhea and loose stool were observed in both males and females, but no deaths were seen in males or females. No macroscopic abnormalities were found in males or females at pathological autopsy at the end of observation, and reduced weight gain was not observed in males or females (JECDB (Access on July 2012)). From the above, because there were no adverse effects at 2,000 mg/kg, the upper limit of the guidance value range, it corresponds to "Not classified" in the oral route. However, due to no data in the other routes, it was classified as "Classification not possible" for specific target organ toxicity (single exposure).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	It is reported that in a 28-day repeated oral administration toxicity test with rats, no apparent effects of administration of the test substance were observed in any test item, and the NOEL was 1,000 mg/kg/day (converted guidance value: 311.1 mg/kg/day) above the guidance value range (JECDB (Access on July 2012)). Therefore, it corresponds to "Not classified" in oral administration. However, because effects in the other routes (inhalation, dermal) are unknown due to no data, it was classified as "Classification not possible" for specific target organ toxicity (repeated exposure).	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2012	GHS Classification Guidance by the Japanese Government （July, 2010）
