FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Solid (GHS definition)	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	Based on the rat LC50 value of > 12.5 mg/L/4hrs (SIDS (Access on Dec. 2010)), the substance was classified as "Not classified". This study was carried out with dust or mist generated by nebulizing the substance which melted at 95 - 115 degrees centigrade (melting point: 80.5 degrees centigrade). As relevant information, the saturated vapor pressure concentration was 0.0001 mg/L (SRC Phys Prop (Access on Dec. 2010).	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	In the skin irritation test in rabbits in which 50% suspension of the substance in ethanol was occlusively applied for up to 1, 5, 15 minutes and 20 hours, 20-hour exposure caused mild erythema on the back and ears of the male rabbits after 24 hours, and symptoms disappeared in 7 days (SIDS (Access on Dec. 2010)). In another rabbit test in which treatment of suspension in olive oil (10%, 20% and 50%) for 20-hour, 20% suspension on the back caused very slight erythema after 1 and 2 days of application (symptoms disappeared in 3 days), and 50% suspension on the ears caused marked erythema associated with edema over 4 days (SIDS (Access on Dec. 2010)). It was also reported that open exposure of the substance caused "slightly irritating" by judging from the grade 3 for irritation (mean score was unclear) and "moderately irritating" by judging from the Draize score of 2.63 to 8.00 after 24 and 72 hours (SIDS (Access on Dec. 2010)). In the guinea pig test, the substance resulted as "slightly irritating" (SIDS (Access on Dec. 2010)). Based on these documents, the substance was classified as Category 2.

3	Serious eye damage/eye irritation	Category 2	Warning	H319	P305+P351+P338 P337+P313 P264 P280	In the rabbit test in which the solid substance was directly inserted into the conjunctival sac of 2 animals, erythema with slight to significant conjunctival edema were observed in one animal at 1 to 24 hours after instillation, and corneal opacity was observed in one animal after 8 days (SIDS (Access on Dec. 2010)). In another rabbit test, instillation of the 10% olive oil solution for 2 animals caused erythema after 10 minutes, and erythema and edema after 1 to 3 hours. Symptoms disappeared after 24 hours of instillation (SIDS (Access on Dec. 2010)). It was also reported that the substance caused "slight injury" by judging from the grade 3 (mean score was unclear) and caused conjunctival erythema in 5 of 6 animals and chemosis in 4 of 6 animals (no corneal involvement) (SIDS (Access on Dec. 2010)). Based on these documents, the substance was classified as Category 2.	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）

As relevant information, the substance was classified as "Sh" in the assessment of MAK/BAT (MAK/BAT (2009)).	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
5	Germ cell mutagenicity	Not classified	- -	-	-	The substance was classified as "Not classified" based on the negative results in the micronucleus test using mice intraperitoneally administered (in vivo mutagenicity test in somatic cells) (SIDS (Access on Dec. 2010)). As relevant information, as for in vitro studies, negative results in the Ames test using bacteria and the micronucleus test using Chinese hamster were reported (SIDS (Access on Dec. 2010)).	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
7	Reproductive toxicity	Classification not possible	- -	-	-	In the oral administration study in wistar rats (day 6 - 19 postcoitum) (OECD TG414, GLP-compliant), at the high dose level of 90 mg/kg/day, general toxicity (blood system and liver) of the maternal animal was observed. But, no effect on gestational parameters and fetal development were observed (SIDS (Access on Dec. 2010)). In the 3-month oral administration study in male and female wistar rats (OECD TG408, GLP-compliant), the general toxicity (blood system and liver) was seen at 60 mg/kg/day. On the other hand, changes in the weights of reproductive organs were not seen in 120 mg/kg/day (SIDS (Access on Dec. 2010)). However, since there was no data for the development of postnatal offspring, the classification was not possible.	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）

In the acute oral study in rats (6400 mg/kg group: equivalent to "Not classified" according to the guidance document), dyspnea and apathy were reported without any abnormalities in the organs (SIDS (Access on Dec. 2010)). It was also reported in the acute dermal studies in rabbits (4000 mg/kg) or rats (2500 mg/kg) that no pathological changes were found in the surviving animals (SIDS (Access on Dec. 2010)). Based on the information described above, the substance was classified as Category 3 (respiratory tract irritation).	FY2010	GHS Classification Guidance by the Japanese Government （July, 2010）
9	Specific target organ toxicity - Repeated exposure	Category 1 (nerve, heart), Category 2 (liver)	Danger Warning	H372 H373	P260 P264 P270 P314 P501	In the 3-month oral dose study in male and female rats (OECD TG 408, GLP-compliant), shortening in prothrombin time, decreases in AST and ALT, an increase in liver weight in females, and centrilobular hypertrophy of the liver in both sexes were observed at the dose level of 60 mg/kg/day (equivalent to Category 2) (SIDS (Access on Dec. 2010)). In the 4-week oral dose toxicity study in ten female Wistar rats, hypothermia, unstable gait, piloerection, pale skin, decreased serum cholinesterase activity, elevation of erythrocyte cholinesterase activity, erosion and ulcer in stomach, liver enlargement, axonal degeneration in proximal sciatic nerve were observed at 7.8 mg/kg/day (converted value as that of 90-day study) (equivalent to Category 1) (SIDS (Access on Dec. 2010)). Moreover, in the oral dose toxicity studies in rabbits and dogs, neuronal disorder (ataxia, listlessness of extremities) with injuries in the brain and spinal cord, and cardiac enlargement were observed at the dose levels equivalent to Category 1 of the guidance values (SIDS (Access on Dec. 2010)). Furthermore, in the 5-week (dust) inhalation study in male and female beagle dogs, neuronal disorder of hind limbs at the dose level of 0.028 mg/L/day (converted value as that of 90-day study) (equivalent to Category 2), and scattered degeneration in the spinal cord at the dose level of 0.0097 mg/L/day (converted value as that of 90-day study) (equivalent to Category 1) were reported (SIDS (Access on Dec. 2010)). In the 4-week (dust) inhalation study in male and female beagle dogs, neuronal disorder (impaired gait) at the dose level of 0.0294 mg/L/day (converted value as that of 90-day study) (equivalent to Category 2), and histopathological changes in central nervous system at the dose level of 0.0056 mg/L/day (converted value as that of 90-day study) (equivalent to Category 1) were also reported (SIDS (Access on Dec. 2010)). Therefore, the target organs were considered as the nervous system, heart and liver, and the substance was conclusively classified as Category 1 (nervous system, heart), Category 2 (liver).
