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	Based on reports of LD50 values of 895 mg/kg (male), 920 mg/kg (female), and 930 mg/kg (male) for rats (SIDS (2006), NICNAS (2001)), it was classified in Category 4.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Based on a report of an LD50 value of >10,000 mg/kg for rabbits (SIDS (2006), NICNAS (2001)), it was classified as "Not classified."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Vapours)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	Based on reports of LC50 values (4 hours) of >5.1 mg/L (SIDS (2006), NICNAS (2001)) and >21.6 mg/L (NICNAS (2001)) for rats, it was classified as "Not classified." Besides, the reference values for the dust were used based on the fact that this substance is a solid, there were no vapour pressure data and a description that the test was conducted with the dust.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
2	Skin corrosion/irritation	Not classified	- -	-	-	In a skin irritation test in which this substance was applied to rabbits for 4 hours, the average scores for erythema and edema were 0, and it was judged to be not irritating (SIDS (2006)). In addition, in other studies with rabbits, the results were also not irritating or very slightly irritating (SIDS (2006), NICNAS (2001)). From the above results, by deleting the information sources in List 3, and adding the ones in List 1, the category was changed according to the revision of the GHS classification guidance for the Japanese Government.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
3	Serious eye damage/eye irritation	Not classified	- -	-	-	In an eye irritation test with rabbits, the average scores for iritis, keratitis and conjunctivitis were all 0, and it was judged as not irritating (SIDS (2006)). In addition, although there is a description that in another test with rabbits, slight conjunctivitis was observed 48 hours after application (NICNAS (2001)), it was judged as not irritating in IUCLID (2000) which was a reference source of this description. From the above results, it was classified as "Not classified."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Respiratory sensitization	Category 1	Danger	H334	P304+P340 P342+P311 P261 P284 P501	There are case reports that asthma symptoms were induced by inhalation exposure in humans (SIDS (2006), NICNAS (2001)). Since it was concluded in SIDS (2006) and NICNAS (2001) that this substance was positive in respiratory sensitization, it was classified in Category 1.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	There are two sensitization tests with guinea pigs (OECD TG 406, GLP-compliant). In one study, only slight erythema was observed (1/20 animals in the treatment group, 3/20 animals in the control group), therefore, it was judged as non-sensitizing (SIDS (2006)). In the other test, after induction, positive results were obtained for the challenge by intradermal injection, and negative results were obtained for the challenge by epidermal application (SIDS (2006), NICNAS (2001)). In humans, there are both results in patch tests indicating non-sensitizing (SIDS (2006)) and sensitizing (NICNAS (2001)). From these reports, it was determined in SIDS (2006) and NICNAS (2001) that this substance was a sensitizer. From the above results, although there were both negative and positive results, the positive results were obtained in humans and animals, and it was also concluded that it is sensitizing in assessment reports in other countries. Therefore, it was classified in Category 1.	FY2014	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 a micronucleus test with mice and an unscheduled DNA synthesis test with rats (IUCLID (2000), NICNAS (2001)). As for in vitro, it was negative in a bacterial reverse mutation test, mammalian cell chromosome aberration test, and an unscheduled DNA synthesis test with cultured hepatocytes of rats (SIDS (2006), IUCLID (2000), NICNAS (2001)).	FY2014	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.	FY2014	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.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
8	Specific target organ toxicity - Single exposure	Category 2 (systemic), Category 3 (respiratory tract irritation)	Warning	H371 H335	P308+P311 P260 P264 P270 P405 P501 P304+P340 P403+P233 P261 P271 P312	This substance was irritating to the respiratory tract. There were multiple cases in humans, but no data were available for classification. As for experimental animals, dyspnea, respiratory distress, and nasal discharge by inhalation exposure with rats, and nasal discharge, irregular breathing, sedation, ataxia, dyspnea, diarrhoea, muscular hypotonia and mydriasis by oral administration to rats were reported (SIDS (2006), ACGIH (7th, 2001), NICNAS (2001)). Besides, the findings by oral administration to rats were observed within the concentration range corresponding to Category 2. Based on these findings, it was considered to be irritating to the respiratory tract by inhalation, and by the oral route, effects on multiple organs were observed, however, effects on specific organs were not confirmed. From the above, it was classified in Category 2 (systemic toxicity), in addition, Category 3 (respiratory tract irritation).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	There were no adverse findings by repeated exposure to this substance with humans. As for experimental animals, in a study in which rats were administered by feeding for 90 days, no toxic findings were observed within or lower than the dose range for Category 2 (1,000 ppm: equivalent to 100 mg/kg/day), and even at a dose exceeding Category 2 (3,000 ppm: equivalent to 225 mg/kg/day), only changes in the gastrointestinal tract epithelial lining (necrosis, atrophy) considered to be due to irritation were observed (SIDS (2006), ACGIH (2001), NICNAS (2001)). Therefore, although it was considered to be equivalent to "Not classified" by the oral route, there was no toxic information in other routes, and it was classified as "Classification not possible" due to lack of data. Besides, in the previous classification, it was classified as "Not classified" only by the oral route information.

11	Hazardous to the aquatic environment Short term (Acute)	Not classified	- -	-	-	It was classified as "Not classified" from 72-hour ErC50 >1000 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1999)), 48-hour EC50 = 133 mg/L for crustacea (Daphnia magna) (SIDS, 2005), and 96-hour LC50 >100 mg/L for fish (Oryzias latipes) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1999)).	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
11	Hazardous to the aquatic environment Long term (Chronic)	Not classified	- -	-	-	If chronic toxicity data are used, then it is classified as "Not classified" from 72-hour NOEC = 3.2 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1999)) although environmental dynamics of the inorganic compound are unknown. If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified as "Not classified" because it corresponds to "Not classified" in acute toxicity for fish and is not water-insoluble (water solubility = 549 g/L (NITE, 2014)). From the above results, it was classified as "Not classified."	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.	FY2014	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
