| 5 | Germ cell mutagenicity | Category 2 |
 Warning |
H341 | P308+P313 P201 P202 P280 P405 P501 |
There are no data on this substance. This substance is a polymer and that of standard technical grade consists of 4,4'-methylenedianiline (4,4'-MDA: CAS number: 101-77-9) between ca. 47 and < 65%, 2,4'-MDA (1.4 to ca. 10%), 2,2'-MDA (ca. 0.2 to 3%), oligomers of MDA (ca. 38.4 to <65%) and on (ECHA SVC Support Document (2011), EU-RAR (2001)). Among components with a content of 1% or higher, data on germ cell mutagenicity was obtained for 4,4'-MDA, but could not be obtained for 2,4'-MDA and 2,2'-MDA. Therefore, germ cell mutagenicity of 4,4'-MDA, a major component of this substance is described below: As for in vivo, for 4,4'-MDA, a somatic cell mutagenicity test (a micronucleus test, a chromosomal aberration test) was positive (NTP DB (Access on March 2006), EU-RAR (2001), SIDS (2002)). As for in vitro, a bacterial reverse mutation test, a mouse lymphoma test, a chromosomal aberration test, and a sister chromatid exchange test in cultured mammalian cells were all positive (Initial Risk Assessment, NITE (2007); EU-RAR (2001); SIDS (2002)). Because this substance contains 1.0% of 4,4'-MDA or more, this substance was classified in Category 2. |

| 6 | Carcinogenicity | Category 1B |
Danger |
H350 | P308+P313 P201 P202 P280 P405 P501 |
This substance is a mixture containing 4,4'-methylenedianiline (4,4'-MDA: CAS number: 101-77-9), and classification results of 4,4'-MDA can be applied. As for classification results of 4,4'-MDA by other organizations, it was classified as follow: Group 2B by IARC (IARC 39 Sup.7 (1987)), A3 by ACGIH (ACGIH (7th, 2001)), R by NTP (NTP RoC (13th, 2014)), 2B by Japan Society for Occupational Health (The Recommendation of Acceptable Concentration (2015)), and Carc. 1B by EU (ECHA CL Inventory (Access on August 2015)) respectively. Among these, according to Classification Guidance, EU classification corresponds to Category 1B, and it corresponds to Category 2 except EU and NTP. In EU-RAR (2001) assessment, in a carcinogenicity test of 4,4'-MDA in rats and mice in an oral route, significantly increased incidences of tumors in the thyroid and liver were observed, and rat showed bladder transitional epithelial papillomas although in a lower frequency. Because they are rare tumors, there is the comment that association of administrating this substance cannot be excluded. Namely, it was concluded that there is sufficient evidence in experimental animals (EU-RAR (2001)). On the other hand, it was suggested that bladder cancer might be associated with occupational exposure to this substance in humans, but it was concluded that no clear conclusion could be drawn for carcinogenicity from epidemiological knowledge. From these, 4,4'-MDA is a carcinogen in experimental animals, but there is insufficient information on human carcinogenicity. Therefore, 4,4'-MDA was classified in Category 2 (corresponding to Carc. 1B in the current CLP classification) according to the criteria of the Directive 67/548/EEC (EU-RAR (2001)). As above, by adopting the carcinogenicity classification results of 4,4'-MDA which EU conducted after IARC evaluation (consistent with the 2014 NTP assessment) and because it is also applicable to this substance, this substance was classified in Category 1B in this hazard class. Besides, by applying the results of 4,4'-MDA in carcinogenicity evaluation of this substance, this substance will be classified in Category 1B. Therefore, EU classed this compound in SVHC (ECHA SVHC Support Document (2011)). |

| 7 | Reproductive toxicity | Category 2 |
Warning |
H361 | P308+P313 P201 P202 P280 P405 P501 |
This substance is a mixture containing 4,4'-methylenedianiline (4,4'-MDA: CAS number: 101-77-9), and classification results of 4,4'-MDA can be applied. Information on reproductive effects of 4,4'-MDA is very limited. There is the only description that pregnant rats were administered by gavage with hydrochloride of 4,4'-MDA at 50 mg/kg/day on day 14 to 20 of gestation and had a Caesarean section on day 21 of gestation, and effects on the liver in maternal animals (discoloration, proliferation in the bile ducts, and proliferation and initial signs of fibrosis in the portal region) and histological changes in the liver in fetuses (fatty infiltration of liver parenchyma (too severe to distinguish the bile ducts and portal area)) were observed (DFGOT vol. 7 (1996)). Besides, it is written that pregnant rats or rabbits were administered by gavage of a preparation containing about 30% 4,4'-MDA (EMP IV) during an organogenetic period in teratogenicity tests, both of which did not observe fetal toxicity and malformations in fetuses even administered up to the doses where maternal animals died. (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012)) From the above, it is judged that Category 2 classification is valid for 4,4'-MDA from the data described in DFGOT similarly to the previous classification. Because the classification results of 4,4'-MDA are also applicable to this substance, this substance was classified in Category 2 in this hazard class. |

| 8 | Specific target organ toxicity - Single exposure | Category 1 (central nervous system, visual organs, heart, liver, kidney) |
Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
There are no data on this substance. This substance is a polymer and that of standard technical grade consists of 4,4'-methylenedianiline (4,4'-MDA: CAS number: 101-77-9) between ca. 47 and < 65%, 2,4'-MDA (1.4 to ca. 10%), 2,2'-MDA (ca. 0.2 to 3%), oligomers of MDA (ca. 38.4 to <65%) and on (ECHA SVC Support Document (2011), EU-RAR (2001)). Among components of 1% or higher, data on single exposure toxicity was obtained for 4,4'-MDA, but could not be obtained for 2,4'-MDA and 2,2'-MDA. Therefore, single exposure toxicity of 4,4'-MDA, a major component of this substance is described below. As for humans, the following is reported as acute toxic signs of 4,4'-MDA reported in oral, inhalation, and dermal routes: acute hepatitis with nausea, vomiting, fever, chill, right upper quadrant pain, and jaundice, hepatic enlargement, cholangitis, inflammation and congestion of bile in the portal region, necrosis and degeneration of hepatocytes, myocardial disorder, ECG abnormalities suggesting myocardial injury, and retinal disorder (Initial Risk Assessment, NITE (2007); Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012); EU-RAR (2001); ACGIH (7th, 2001)). As for experimental animals (rats, mice and so on), the following was reported: necrosis of hepatocytes with hemorrhage, multifocal cholangiolar hepatitis, necrosis of bile ducts, liver and kidney damage, and blindness due to retinal atrophy in oral administration of 4,4'-MDA (at the dose corresponding to Category 1); and tremor, hunched posture, and exophthalmos in inhalation exposure (at the dose corresponding to Category 1) (Initial Risk Assessment, NITE (2007); ACGIH (7th, 2001); EU-RAR (2001); ATSDR (1998)). As above, effects of 4,4'-MDA were observed in the central nervous system, visual organs, heart, liver, and kidney. Because this substance contains 10% of 4,4'-MDA or more, this substance was classified in Category 1 (central nervous system, visual organs, heart, liver, kidney). |

P260 P264 P270 P314 P501 |
There are no data on this substance. However, this substance is a polymer and that of standard technical grade consists of 4,4'-methylenedianiline (4,4'-MDA: CAS number: 101-77-9) between ca. 47 and < 65%, 2,4'-MDA (1.4 to ca. 10%), 2,2'-MDA (ca. 0.2 to 3%), oligomers of MDA (ca. 38.4 to <65%) and on (ECHA SVC Support Document (2011), EU-RAR (2001)). Among components of 1% or higher, data on repeated toxicity was obtained for 4,4'-methylenedianiline (4,4'-MDA: CAS number: 101-77-9). Data on repeated dose toxicity could not be obtained for 2,4'-MDA (CAS number: 1208-52-2) and 2,2'-MDA (CAS number: 6582-52-1). Repeated toxicity of 4,4'-MDA (CAS number: 101-77-9), a major component of this substance is described below. As for humans, in a single exposure and short-term exposure for two weeks or shorter, acute hepatitis was mainly reported, and cases with ECG abnormalities were also reported (Initial Risk Assessment, NITE (2007); ATSDR (1998); EU-RAR (2001)). As for experimental animals, as repeated dose toxicity, in a 103-week toxicity test using rats in drinking water administration, fatty liver, cysts and hyperplasia of thyroid follicular epithelial cells were observed at 150 ppm (9 to 10 mg/kg/day) or higher, and kidney mineralization (males) at 300 ppm (16 mg/kg/day). In a 3-month toxicity test using rats in drinking water administration, the following was observed: nephrocalcinosis and degeneration of thyroid follicular epithelial cells at 80 ppm (males: 7.5 mg/kg/day, females: 8 mg/kg/day) or higher; decreases in food and water consumption, reduced weight gain, anemia, increases in ALP, ALT, AST, urea nitrogen, bile pigments, and cholesterol, focal nodular hyperplasia of thyroid follicular epithelial cells at 400 ppm (males: 22 mg/kg/day, females: 23 mg/kg/day) or above; and increases in white blood cells and neutrophils, prolonged prothrombin time, hyperplasia of small bile ducts of the liver, hyperplasia of thyroid follicular epithelial cells at 800 ppm (males: 31 mg/kg/day, females: 32 mg/kg/day) (Initial Risk Assessment, NITE (2007)). Among these effects, effects on liver, thyroid, and kidney were observed in the range of Category 1, and effects on blood were found in the range of Category 2. As above, effects of 4,4'-MDA were observed in liver and heart in humans, and effects on liver, thyroid, and kidney were observed in the range of Category 1, and effects on blood were found in the range of Category 2 in experimental animals. Because this substance contains 10% of 4,4'-MDA or more, this substance was classified in Category 1 (liver, heart, thyroid, and kidney), Category 2 (blood system). |
