m phenylenediamine when treated with nano2

PubChem Substance ID 329761716. In the studies carried out to date, m‐phenylenediamine was not carcinogenic after oral administration; when the substance was administered by subcutaneous injection, tumours developed at the injection site. The dinitrobenzene is prepared by dinitration of benzene. The preparations were applied for 3 hours to a 20 × 25 cm area of skin. Column Method. Because of the clearly genotoxic properties of the substance, m‐phenylenediamine is to be classified in Section III B in the "List of MAK and BAT Values" until the inconsistencies in the in vivo studies have been clarified. m-Phenylenediamine, also called 1,3-diaminobenzene, is an organic compound with the formula C 6 H 4 (NH 2) 2.It is an isomer of o-phenylenediamine and p-phenylenediamine.It is a colourless solid. The published results of short‐term tests with m‐phenylenediamine are shown in Table 1. View information & documentation regarding o -Phenylenediamine, including CAS, MSDS & more. We hypothesized that a similar effect might occur in the esophagus when the luminal pH … and you may need to create a new Wiley Online Library account. Embryotoxic or teratogenic effects were not observed [20]. For (PBT) and (ED) Potential means that the concern is under assessment in the PBT or ED assessment list, and the outcome indicates a potential ED. In an early study of the local effects of the phenylenediamines, m‐phenylenediamine was found to have no effect when the solid was rubbed into a 1 to 5 cm2 area of human skin (no other details). A carcinogenicity study has also been carried out with a hair dye preparation (PP‐7585) whose ingredients included 0.17 % m‐phenylenediamine base and 1.5 % p‐phenylenediamine. 2. Granted, p-phenylenediamine (PPD) has been the leading permanent hair coloring agent or oxidative hair dye in most of the Western world since its introduction in the 1880s, 1 and it has been a problematic agent almost since its debut. A 14C-m-phenylenediamine dose of 240 mg/kg body weight was applied occlusively to the intact, shaved dorsal skin (4 cm2) of groups of 7 male rats for 24 hours. The cultured rat hepatocytes produced the same metabolites together with some not better identified glucuronic acid conjugates. occurred in rats treated with 18.0 mg/kg/day m- phenylenediamine. 2, or Repr. If you do not receive an email within 10 minutes, your email address may not be registered, 12 mg/kg group: every second day for 68 weeks; 24 mg/kg group: every second day for 20 weeks. During this period, urine and faeces were collected; then all the animals were killed. A scratch test with m‐phenylenediamine produced positive reactions in 8 % of the persons who also suffered from eosinophiluria and had urinary m‐phenylenediamine levels of 0.3 to 40 µg/100 ml. For (PBT) and (ED) Potential means that the concern is under assessment in the PBT or ED assessment list, and the outcome indicates a potential ED. After metabolic activation, m‐phenylenediamine yields positive results in the Ames test. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. The findings are, however, poorly documented [6]. Of a dose of 1.5 g m‐phenylenediamine hydrochloride, 60 mg could be detected spectrophotometrically in the blood of the animals by means of the indoaniline reaction. The hair dye preparation was mixed 1:1 with 6 % hydrogen peroxide immediately before use and applied to the dorsal skin of the animals on three different sites (to avoid skin irritation), twice weekly for 13 weeks in doses of 1 ml/kg body weight. In guinea pigs in the only sensitization study carried out to date, m‐phenylenediamine was a moderate sensitizer compared with the highly sensitizing p‐phenylenediamine. In a study of hair dyes, a group of 6 male and 6 female New Zealand White rabbits was treated with a preparation whose ingredients included 1.5 % m‐phenylenediamine and 1 % o‐phenylenediamine. The effects of sodium nitrite (NaNO2) and catechol or 3-methoxycatechol in combination were examined in male F344 rats. Later urine samples had only very little mutagenic activity [41]. Excretion took place mainly in the urine and was complete within 7 days; 81 % of the absorbed radioactivity was found in the urine in group A and 51 % in group B. It is mainly used as a component of engineering polymers and composites like kevlar.It is also an ingredient in hair dyes and is occasionally used as a substitute for henna In a study of hair dyes, a group of 6 male and 6 female New Zealand White rabbits was treated with a preparation whose ingredients included 1.5 % m‐phenylenediamine and 1 % o‐phenylenediamine. In parallel, a positive control group was treated with acetylsalicylic acid and a negative control group with distilled water. rat, Wistar‐King, 5 per group, sex n.s. However, application of a 10 % alcoholic solution resulted in slight erythema [4]. Similarly, after topical application of the substance, tumours were not observed [16]. The urine collected from the rats between 24 and 48 hours after the start of exposure yielded positive results in the Ames test (Salmonella typhimurium TA98) after metabolic activation. with H20: он Get help answering Mole Correct with HBF4: edit Br Get help answering M … ICSE X Chemistry Chemical Bonding - Ionic Compounds and Covalent Compounds. Applications. But being unstable it will react with the water present and will give methanol as final product. In a 6‐week feeding study, groups of 5 female Fischer rats were given either 0, 1000 or 2000 ppm m‐phenylenediamine in the diet or 1000 ppm m‐phenylenediamine together with 5000 ppm 2,4‐diaminoanisole. A 14C‐m‐phenylenediamine dose of 240 mg/kg body weight was applied occlusively to the intact, shaved dorsal skin (4 cm2) of groups of 7 male rats for 24 hours. It is isomeric with m -phenylenediamine and p -phenylenediamine . Phenylenediamine is present in black dyes widely used in permanent hair dyes and leather, printer's ink, fax machine ink, and lithography (12 A).It can cause contact dermatitis (13 A).The risk is particularly increased in those who also use temporary black tattoos, and as such tattoos have become fashionable among adolescents, the risk of sensitization has increased. Urine and faeces were collected for up to 7 days; then the rats were killed and the treated skin (4 cm2) removed. Linear Formula C 6 H 4 (NH 2) 2. LD50 Oral - Rat - 280 mg/kg(m-Phenylenediamine) LC50 Inhalation - Rat - male - 4 h - 3.2 mg/l(m-Phenylenediamine) Skin corrosion/irritation Skin - Rabbit(m-Phenylenediamine) Result: No skin irritation Serious eye damage/eye irritation Eyes - Rabbit(m-Phenylenediamine) Result: Irritating to eyes. m-Phenylenediamine and m-Phenylenediamine Sulfate Dr. Bergfeld noted that the Draft Report on m-Phenylenediamine and m-Phenylenediamine Sulfate, reviewed in Teams on the preceding day, was added to today's agenda. EC Number 203-404-7. Wang M(1), Cheng G, Khariwala SS, Bandyopadhyay D, Villalta PW, Balbo S, Hecht SS. and sorbed metal ion was eluted with 0.5 M HNO3 (10 mL). 24 mg/kg group: delayed body weight gain, decreased haemoglobin levels, decreased erythrocyte and leukocyte counts, damage to kidneys, spleen and lungs; skin surface at the injection site scabby, scarred and pigmented; 24 mg/kg group: 1 animal with 1 sarcoma at the injection site after about 5 months, no other tumours, m‐phenylenediamine (in arachis oil), purity 99.97–100%, rat, Sprague‐Dawley, 30 ♂ and 30 ♀ per group; control: 30 ♂ and 30 ♀, animals observed until they died or were killed in a moribund state, mortality not increased, body weight gain normal for ♀, for ♂ delayed about 7.6 % in both dose groups; liver cell necrosis in 10/60 (25 mg/kg body weight) and 8/60 (8.33 mg/kg body weight), animals with malignant tumours at the injection site, rat, Fischer 344, 50 ♂ and 50 ♀ per group; control: 50 ♂ and 50 ♀, mortality n.s., delayed body weight gain in ♂ ♂ of the 400 ppm group; renal disorders and effects in the nasal cavity in ♀ ♀ of the 400 ppm group; urea nitrogen, creatinine and potassium levels increased, albumin level decreased in all animals of the 400 ppm group, rat, CD, 25 ♂ and 25 ♀ per group; control: 25 ♂, 96 weeks; 24‐week post‐exposure observation period, mouse, B6C3F1; 0.02% group: 50 ♂ and 50 ♀; 0.04% group: 56 ♂ and 59 ♀; control: 50 ♂ and 50 ♀. The males were then mated each with 2 females and the females killed 17 days later. Mutation Research 241(3): 313-323. For (C), (M), and (R) it means that the concern is suspected in a Harmonised C&L (CLP Regulation Annex VI), as Carc. There were no changes in the parameters examined for the dominant lethal test: dead implants per pregnant female, dead implants per total implants and proportion of females with 1 or more dead implant. 4 ( NH 2 ) 2 to prevent further reduction and Classifications for the cells of substance!
