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 LD50 values of 1200 mg/kg and 2700 mg/kg for rats (JECFA (2003)), the lower value was adopted and the substance was classified into Category 4.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Based on a LD50 value of >5000 mg/kg for rabbits (IUCLID (2000)), the substance was classified as "Not classified".	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Classification not possible due to lack of data. As relevant information, although there is information of a LC50 value of 19,500 mg/m3 (5,668 ppmV) (RTECS (2006)), the exposure period is not clear. Since the LC50 value was lower than 90% of saturated vapour pressure concentration (15000 ppm), the test was considered to be conducted for vapour with almost no included mists.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
2	Skin corrosion/irritation	Not classified	- -	-	-	Based on results of not irritating (skin primary irritation index (PII): 0.31) in a rabbit test (OECD TG404) (IUCLID (2000)) and slightly irritating (PII: 2.75 and 3.0) after application for 4-hour in other two rabbit tests (IUCLID (2000)), the substance was classified as "Not classified" in JIS Classification (correspond to Category 3 or "Not classified" in GHS classification). As relevant information, in EU classification, the substance is classified into Xi; R36/38 (EU-Annex I (access on July 2009)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Category 2A	Warning	H319	P305+P351+P338 P337+P313 P264 P280	Based on results of AOI 54.66 (24-hour) and "highly irritating" in a rabbit test (OECD TG405) (IUCLID (2000)), the substance was classified into Category 2A. As relevant information, in EU classification, the substance is classified into Xi; R36 (EU-Annex I (access on July 2009)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
4	Skin sensitization	Classification not possible	- -	-	-	Classification not possible due to lack of data. There is a report that the substance "produced no sensitization reactions" in a maximization test on 25 volunteers (IUCLID (2000)). This information is reported in a document in List 2 and the positive ratio or data for the control group is not clear.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Classification not possible	- -	-	-	Classification not possible due to lack of data from in vivo mutagenicity tests. From in vitro mutagenicity tests, there is a report of a negative Ames Test (JECFA (2003)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Classification not possible	- -	-	-	In a rat developmental test by oral administration during organogenesis period, no maternal, embryo or fetal toxic effects were observed (JECFA (2003)). In a female mice test involving i.p. injections for 28 days, mating with untreated males on the day 10, there were no effects on fertility (JECFA (2003)). However, this information is incomplete as evidence for classification because of exposure to females only, one dosage and the small number of animals (8/group). Therefore, classification was not possible due to lack of data for sexual function and fertility.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	In inhalation tests with rats for 4 - 11 weeks or 11 - 16 weeks, effects on the mitral cells of the olfactory bulb or relationship between concentration of the test substance and drug metabolizing enzymes were reported (IUCLID (2000)). However, these tests are not standard, repeated exposure test, therefore information required for classification are not available because of few examination items. Classification was not possible due to lack of data.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
