P302+P352
P362+P364 P280 P312 P321 P501 |
Among five LD50 values for rabbits [1,280 mg/kg, 2,000 mg/kg (the above two, Environmental Risk Assessment for Chemical Substances vol. 4 (Ministry of the Environment, 2005)), 1,300 mg/kg (ECETOC TR 95 Volume II (2005)), 1,290 mg/kg, 3,900 mg/kg (the above two, PATTY (5th, 2001))], four corresponded to Category 4, and one corresponded to "Not classified." Therefore, it was classified in Category 4 to which most corresponded. |

H331 |
P304+P340
P403+P233 P261 P271 P311 P321 P405 P501 |
It was classified in Category 3 based on an LC50 value of 4,700 mg/m3 for rats by 7-hour inhalation exposure (converted 4-hour equivalent value: 6.218 mg/L = 1,998 ppm) (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). Besides, because the LC50 value (4.7 mg/L/7 hours) was lower than 90% of the saturated vapour pressure concentration (38.9 mg/L), the reference value of gas was applied as a vapour with little mist. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | No data available. |
2 | Skin corrosion/irritation | Not classified |
- |
- | - | On the basis that it was not irritant in a test in which 0.5 mL of undiluted this substance was applied to the rabbit skin for 4 hours (ECETOC TR95 Volume II (2005)), it was classified as "Not classified." Besides, in other tests with rabbits, it was reported that the application of 483 mg for 24 hours was slightly irritating (IUCLID (2000)), and that repeated and prolonged exposure to the rabbit skin resulted in no irritation (PATTY (5th, 2001)). |
3 | Serious eye damage/eye irritation | Not classified |
- |
- | - | In a test in which 0.1 mL of undiluted this substance was applied to the conjunctival sac of rabbits (OECD TG 405), the average irritation scores 24 hours to 72 hours after application were 1.3-1.1 for conjunctival redness, 0.5-0.2 for chemosis, and 0.2-0.0 for corneal opacity, and it was judged as not irritant (ECETOC TR 95 Volume II (2005), BUA 198 (1996)). Therefore, it was classified as "Not classified." Besides, as information in humans, there is a report on the person who developed eye irritation after exposure but fully recovered after 48 hours (PATTY (5th, 2001)), but it was not adopted for classification because it was a report on one person. |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | No data available. |
4 | Skin sensitization | Classification not possible |
- |
- | - | It is described that this substance was not a skin sensitizer in a maximization test with guinea pigs (CICAD 67 (2010)), but because there were no further descriptions, and the details such as test conditions and test results are unknown, it was classified as "Classification not possible." |
5 | Germ cell mutagenicity | Not classified |
- |
- | - | There are reports on multiple dominant lethal tests with mice or rats by oral or inhalation exposure (in vivo heritable germ cell mutagenicity tests), most of them gave negative results although some weakly positive ones, and negative results were reported in some chromosomal aberration tests (in vivo mutagenicity tests) by oral or inhalation exposure of mice or rats (the above, Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). Therefore, it was classified as "Not classified." Besides, two micronucleus tests with mice (in vivo mutagenicity tests) were negative and weakly positive (ECETOC TR 95 Vol. II (2005)). As for in vitro tests, all of an Ames test, a mouse lymphoma test, an HGPRT test and a GPT test with Chinese hamster CHO cells gave negative results, and a chromosomal aberration test with humans lymphocytes was negative after 1-hour culture but positive after 24-hour culture (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). |

7 | Reproductive toxicity | Category 1B |
Danger |
H360 |
P308+P313
P201 P202 P280 P405 P501 |
It was classified in Category 1B based on the following reasons. In reproductive tests according to the NTP continuous breeding protocol in which male and female mice or rats were dosed by drinking water before mating, through mating, parturition, and nursing periods, decreased numbers of live births, decreased fertility index, and decreased numbers of pregnancies were seen (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). A decrease in fertility index was not severe in the drinking water administration test with rats, but it was clearly observed in reproductive tests by gavage, inhalation, or dermal administration (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). Furthermore, in developmental toxicity test by administration to pregnant animals mainly during the organogenesis period, there are reports on fetal deaths, increased incidences of malformations in the fingers of the extremities (syndactyly, brachydactyly, ectrodactyly, polydactyly), skeletal malformations (bifurcated or split cervical vertebral arch), and external malformations (exencephaly) in mice, resorptions, increased incidences of external malformations (arthrogryposis, club foot, anonychia, brachydactyly, ectrodactyly, etc.), visceral malformations (ventricular septal defect, aplasia of the subclavian artery, renal agenesis, renal malformations, dilatation of the renal pelvis, diaphragmatic hernia, ovarian aplasia, etc.), and skeletal malformations (missing phalanges) in rabbits, fetal deaths and the malformations that did not occur spontaneously in the cardiovascular system in rats, and increased fetal deaths in rhesus monkeys (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). Besides, it was classified in R60-61 in the EU (EC-JRC (ESIS) (Access on May 2012)). |

Danger |
H370 |
P308+P311
P260 P264 P270 P321 P405 P501 |
It was classified in Category 1 (central nervous system) based on the following descriptions. As human case reports, a 44-year-old man who drank brandy contaminated by this substance developed coma followed by loss of consciousness (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)), two men (23-year-old, 41-year-old) who mistakenly drank 100 mL of this substance had neurological symptoms such as confusion and excitement (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)), and congested edema was found in the brain and meninx as acute effects of this substance (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). And it was classified in Category 1 (kidney) based on the following reports. In the above cases, necropsy of the 44-year-old man revealed blackening of the kidney and degeneration of the renal tubules, oxalate in the urine was seen in one of the two men of accidental drinking, suspected of having renal disorders, and renal disorders were observed in other three men (18 to 58-year-old) (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). On the other hand, as for animal tests, degeneration and necrosis of the spermatocytes were found after a single dose of 150 mg/kg to rats (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)), and degeneration of the seminiferous germinal epithelium with damage to the primary spermatocytes was reported in rats after 4-hour inhalation exposure to 1,000 ppm (3.11 mg/L) (ACGIH (2006)). Because the doses corresponded to the guidance values for Category 1 in both routes, it was classified in Category 1 (testis). |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (central nervous system, hematopoietic system, testis) |
Danger |
H372 |
P260
P264 P270 P314 P501 |
It was classified in Category 1 (central nervous system, hematopoietic system) based on the results of multiple epidemiological surveys and case reports such as the following. As knowledge in humans, 12 out of 19 workers who used a mixture of this substance (33%) and ethanol for processing collars of shirts developed neurological symptoms such as severe fatigue, lethargy, tremor, and abnormal reflexed anomaly, blood tests revealed many immature leukocytes, and macrocytic anemia considered to be due to effects on the bone marrow was observed in about half of the workers (Environmental Risk Assessment for Chemical Substances vol. 4 (Ministry of the Environment, 2005)), anemia and central nervous system disorders were found in a worker exposed to this substance in a microfilm production facility (ACGIH (2006)), and five persons with encephalopathy and anemia were seen in the workers who used this substance, but after the workplace was improved, and air concentrations of this substance were reduced, no further ill effects were noted (ACGIH (2006)). And it was classified in Category 1 (testis) because oligozoospermia, aspermatogenesis, and a decrease in sperm counts per ejaculation were observed in male shipyard painters, and because, also in animal tests, testicular atrophy and degeneration of the germinal epithelium were found at or 750 ppm (about 70 mg/kg/day) in a 13-week drinking water administration test with rats (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)), and severe degeneration of the seminiferous tubules was reported at or above 100 ppm (0.31 mg/L) in a 13-week inhalation exposure test with rabbits (Initial Risk Assessment Report 88 (NITE, CERI, NEDO, 2007)). |

If chronic toxicity data are used, then it is classified as "Not classified" due to being rapidly degradable (readily biodegradable (a 2-week degradation rate by BOD: 73, 82, 94%) (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1988)), 21-day NOEC > 84.8 mg/L for crustacea (Daphnia magna) (Initial Risk Assessment (NITE, CERI, NEDO, 2007)), and 72-hour NOECr >= 93.2 mg/L for algae (Pseudokirchneriella subcapitata) (Initial Risk Assessment (NITE, CERI, NEDO, 2007)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified as "Not classified" due to 96-hour LC50 > 88.9 mg/L for fish (Oryzias latipes) (Initial Risk Assessment (NITE, CERI, NEDO, 2007)), and being not water-insoluble (water solubility = 1000000 mg/L, PHYSPROP Database, 2009). From the above results, it was classified as "Not classified." |
