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	- -	-	-	Its rat LD50 is 2860 mg/kg bw (SIDS (accessed in August 2008)), which is equivalent to the guidance value of Not classified in JIS classification criteria (equivalent to Category 5 in UN classification).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	Since its rabbit LD50 is ca. 16800 mg/kg bw (SIDS (accessed in August 2008)) or 17300 mg/kg bw (PATTY (5th, 2001)) and its rat LDLo is above 7300 mg/kg bw (PATTY (5th, 2001)), the substance was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Liquid (GHS definition)	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Vapours)	Category 2	Danger	H330	P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501	Its guinea pig LC50 measured with vapour being 275 ppm (8h-exposure) (4h-conversion, 389 ppm, 2.10 mg/L) (PATTY (2000)) is equivalent to the guidance value of Category 2. As relevant information, since the saturated vapour concentration is 488 ppm, the test was considered to be performed with vapour with almost no included mists (evaluation with gas evaluated values).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	Classification not possible due to lack of data. As relevant information, it is reported that its rat LCLo measured with mist is above 1.3 mg/L (4h-conversion, 2.6 mg/L) (quivalent to Category 4 or "Not classified") (PATTY (5th, 2001)).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	In a four-hour skin irritation study according to OECD TG 404 using rabbits, the substance caused moderate irritation with Draize scores of 3.11 for erythema and 1.56 for edema, and the effects were not completely reversible within 14 days (SIDS (accessed in August 2008)). In addition, since its EU Risk Phrase is R36/38, which indicates that its hazard potential is equivalent to Category 2, the substance was classified into Category 2.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Not classified	- -	-	-	In a Draize study with rabbits according to OECD TG 405, the substance caused no significant irritation, with a Draize mean score of 5.17/110, and the effects were completely reversible within six days. Also, in another study using rabbits, 0.5 mL of the substance was applied, and the substance caused slight irritation but no damage, with a Draize score of 1/10 (SIDS (accessed in August 2008)). Therefore, the substance was classified into "Not classified". As relevant information, SIDS concluded that animal tests showed no irritation, but high exposure from the gas phase may cause irritation and profuse lacrimation in humans. PATTY and HSDB also documented that the substance is irritating to humans, but they do not report any symptoms caused by the substance (based on expert judgment).	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	Not classified	- -	-	-	It is documented that in a guinea pig maximization test according to OECD TG 406, the substance was not sensitizing (SIDS (accessed in August 2008)). Therefore, the substance was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Not classified	- -	-	-	Since the substance was negative in a micronucleus test by gavage using mice (SIDS (accessed in August 2008), IUCLID (2000)), and negative in a micronucleus test by inhalation using mice (six-hours/day, 13-weeks) (SIDS (accessed in August 2008)) (both were in vivo mutagenicity tests using somatic cells), the substance was classified into "Not classified". As additional background information, regarding in-vitro mutagenicity tests, Ames tests gave negative results while mouse lymphoma tests yielded both positive and negative results, making the mutagenicity evaluation of the substance inconclusive (SIDS (accessed in August 2008)).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Classification not possible	- -	-	-	The substance did not show any effects on fetuses in a developmental toxicity test using rats performed in accordance with OECD TG 414 (SIDS (accessed in August 2008)). In a mouse inhalation test for 13-weeks (six-hours/day, five-days/week), uretus atrophy and atrophy of the ovary were found (SIDS (accessed in August 2008)). However, since there is no available test data on sexual functions and fertility, and due to the lack of data, classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Category 3 (Narcotic effects)	Warning	H336	P304+P340 P403+P233 P261 P271 P312 P405 P501	In a rat oral administration test, at the doses of 2000 mg/kg or more, the rats exhibited symptoms of sluggishness, prostration, and narcosis (SIDS (accessed in August 2008)), and in humans, signs such as headache and stupor have been reported (SIDS (accessed in August 2008)). Therefore, the substance was classified into Category 3 (narcotic effects).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Category 2 (blood)	Warning	H373	P260 P314 P501	In a 28-day toxicity study in rats with gavage, at the dose of 150 mg/kg/day, hemolytic anemia was seen, which was present at two weeks after the end of the administration period, and as the secondary reactions, increased reticulocyte counts and enhanced extramedullary hematopoesis in the spleen have been reported (SIDS (accessed in August 2008)). While, in a 13-week inhalation test in rats or mice, mainly at the doses of 0.333 mg/L and 0.666 mg/L, changes of blood indexes, including regenerative anemia or reduced erythrocyte count, were reported (SIDS (accessed in August 2008)). Based on the above results, since the developmental doses of hemolytic anemia and related signs, that is, 150 mg/kg/day In the 28-day toxicity study with gavage (90-day conversion, 46.7 mg/kg/day) and 0.333 mg/L and 0.666 mg/L in the 13-week inhalation test are within the guidance values of Category 2, the substance was classified into Category 2 (blood). As relevant information, the toxicological meanings of other changes seen mainly in high-dose groups are unknown.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）

11	Hazardous to the aquatic environment Short term (Acute)	Category 2	- -	H401	P273 P501	Since its 96h-LC50 = 3.2 mg/L (SIDS, 2008) for fish (zebra fish), the substance was classified into Category 2.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
11	Hazardous to the aquatic environment Long term (Chronic)	Not classified	- -	-	-	Although its preexisting classification for acute toxicity is Category 2, it is rapidly biodegradable (BOD degradability, 81% (SIDS, 2006)) and it is estimated to have low bioaccumulation potency (log Kow = 3.78 (SIDS, 2006)), and therefore, the substance was classified into "Not classified".
