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	- -	-	-	Of four rat LD50 values documented (> 7940 mg/kg, > 5000 mg/kg, > 10000 mg/kg, and 1980 mg/kg (IUCLID (2000)), three values fall under the "Not classified" category and one value falls under Category 4. Giving precedence to the more represented category of two, the substance was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Since its rabbit LD50 is > 7940 mg/kg (IUCLID (2000)), the substance was classified into the "Not classified" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Not classified	- -	-	-	Draize tests using rabbits found that a 24-hour application of the substance is not irritating (IUCLID (2000)). Other skin irritation tests using rabbits also discovered that the substance is not irritating (IUCLID (2000)). Based on these results, the substance was classified into the "Not classified" category. As additional information, skin irritation tests using guinea pigs found that the substance produced irritant reactions (IUCLID (2000)).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Draize tests using rabbits found that a 24-hour application of the substance is slightly irritating. Other rabbit tests also revealed that the substance is slightly to moderately irritating. Based on these results, the substance was classified into Category 2B.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Skin sensitization	Category 1	Warning	H317	P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501	Positive results have been obtained in both human patch tests (IUCLID (2000)) and guinea pig tests adopting Buehler's method (IUCLID (2000), HSDB (2003)). Thus, the substance was classified into Category 1.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Dominant lethal assays using rats (in vivo heritable mutagenicity tests using germ cells) found positive results (IUCLID (2000)); however, because only one dose was used in the assays and insufficient test information was provided, evaluation of the results was difficult. Regarding in vitro mutagenicity tests, Ames tests (IUCLID (2000)) and chromosomal aberration tests using CHO cells (HSDB (2003)) yielded negative results while mouse lymphoma assays gave positive results (IUCLID (2000)), and in mutation tests using CHO cells, both negative and positive results have been obtained (IUCLID (2000), HSDB (2003)). Overall, with an expert judgement, we could not validate the positive results obtained in in vivo tests (dominant lethal assays), and we could not reach definitive conclusions based on negative and positive results found in in-vitro tests. Thus, the substance was classified into the "Classification not possible" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Not classified	- -	-	-	No signs of carcinogenicity were detected in the following tests: 2-year oral administration (mixed diet) tests using rats, 79-week forced oral administration tests using mice, 21-month oral administration (mixed diet) tests, and 18-month oral administration tests (IUCLID (2000)). Thus, the substance was classified into the "Not classified" category. In addition, no indication of tumorigenicity was detected in mice that received subcutaneous administration (IUCLID (2000)).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Not classified	- -	-	-	In reproduction tests using female and male rats, no visible signs of poisoning, such as changes in the estrous cycle, delay in conceptions, and increased total embryonic mortality, were detected (IUCLID (2000)). In addition, in several oral administration tests conducted during the organogenetic period using rats, no adverse effects of administration such as incidences of fetal malformation and a decreased number of embryos due to post-implantation loss, were detected (IUCLID (2000)). Based on these results, the substance was classified into the "Not classified" category.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Not classified	- -	-	-	No changes due to administration of the substance were detected, other than changes in organ weight, at the following doses in the following tests: an application of 1000 mg/kg in 4-week oral administration tests using rats (dose: 100, 200, 500, and 1000 mg/kg), an application of 1125 mg/kg in 3-month oral administration (mixed diet) tests (dose: 18, 69, 282, and 1125 mg/kg), an application of 1500 mg/kg in 21-month oral administration (mixed diet) tests (dose: 15, 150, and 1500 mg/kg), and an application of 125 and 250 mg/kg in 56-day forced oral administration tests (dose: 125, 250, and 500 mg/kg) (IUCLID (2000)). Since no effects of administration were detected within the range of guidance doses, the substance was classified into the "Not classified" category. Additionally, in 4-week inhalation exposure tests (6 hours/day and 5 days/week, dose: 0.0044, 0.0098, and 0.0102 mg/L), no pathological changes were observed, other than slight body weight reductions and changes in organ weights and biochemical values, at the highest dose tested (IUCLID (2000)).

10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
