---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 3 |
H301 |
P301+P310 P264 P270 P321 P330 P405 P501 |
From an LD50 value of 178 mg/kg for rats (IARC 11 (1976)), it was classified in Category 3. | |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | No data. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | "Liquids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Vapours) | Category 3 |
H331 |
P304+P340 P403+P233 P261 P271 P311 P321 P405 |
All of three LC50 values for rats (4000 ppm/0.5h, 2800 ppm/1h, and 690 ppm/6h) (IARC 11 (1976)), which are converted into 4-hour equivalent values of 1414 ppm, 1400 ppm, and 845 ppm respectively, correspond to Category 3. Besides, a reference value of gasses as a vapour with hardly included mist was applied because the LC50 values before conversion are lower than 90 % of the saturated vapour pressure concentration (328948 ppm). |
|
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | No data. |
2 | Skin corrosion/irritation | Not classified | - | - | - | On the basis that this substance was mild irritant to skin with recovery within 24 hours (PATTY (5th, 2001)), it was classified as “Not classified” in JIS classification (Category 3 in UN GHS classification). |
3 | Serious eye damage/eye irritation | Category 2B |
H320 |
P305+P351+P338 P337+P313 P264 |
On the basis that this substance was mild irritant to eyes with recovery within 24 hours (PATTY (5th, 2001)), it was classified in Category 2B. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | No data. |
4 | Skin sensitization | Classification not possible | - | - | - | No data. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | No data. |
6 | Carcinogenicity | Classification not possible | - | - | - |
From Group 3 classification in IARC carcinogenicity evaluation (IARC suppl.7 (1987)), it was classified as "Classification not possible." Besides, a weekly subcutaneous administration test in rats at doses of 8 or 16 mg/kg for one year with observation until deaths reported local sarcomas in the high dose group and local fibromas in the low dose group as carcinomas that were not found in the control group (IARC 11 (1976)). |
7 | Reproductive toxicity | Classification not possible | - | - | - | No data. |
8 | Specific target organ toxicity - Single exposure | Category 1 (central nervous system, lung) |
H370 |
P307+P311 P260 P264 P270 P321 P405 P501 |
On the basis that an acute oral toxicity test in rats (an LD50 value was 178 mg/kg) reported depression of the central nervous system with unconsciousness (IARC 11 (1976)), it was classified in Category 1 (central nervous system). And on the basis that an acute inhalation toxicity test in rats (an LC50 value was 2.1 to 3.5 mg/L/4h) reported irritation to mucous membrane, congestion, edema, and hemorrhage in the lungs, it was classified in Category 1 (lung). |
|
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | No data. |
10 | Aspiration hazard | Classification not possible | - | - | - | No data. |
