毒理性
识别和使用:N-甲基二乙醇胺(MDEA)是一种无色液体。MDEA用作中间体,在吸收酸性气体中,作为聚氨酯泡沫的催化剂和pH控制剂。人体研究:无可用的数据。动物研究:MDEA对豚鼠皮肤有刺激性,并显示出诱发过敏性接触性皮炎的潜力。MDEA对眼睛有轻微刺激作用。在大鼠中,反复的皮肤应用MDEA产生剂量相关的刺激作用,但没有证据表明有系统性累积或特定靶器官或组织毒性。怀孕期间,大鼠母体在重复皮肤应用MDEA后出现剂量相关的皮肤刺激。此外,母体毒性也表现为贫血,接受1000 mg/kg/天的大鼠母体出现贫血。尽管有母体毒性,但没有证据表明有发育影响。在鼠伤寒沙门氏菌/微粒体逆向基因突变试验、CHO/HGPRT正向基因突变试验、培养的CHO细胞姐妹染色单体交换试验以及小鼠体内周围血微核试验中,MDEA未表现出遗传毒性。
IDENTIFICATION AND USE: N-Methyldiethanolamine (MDEA) is a colorless liquid. MDEA is used as an intermediate, in absorption of acidic gases, as a catalyst for polyurethane foams, and pH control agent. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: MDEA was irritating to the guinea pig skin, and showed potential to induce allergic contact dermatitis. MDEA caused slight eye irritation. In rats, recurrent skin application of MDEA produced a dose-related irritant effect, but there was no evidence for systemic cumulative or specific target organ or tissue toxicity. Rat dams showed dose-dependent skin irritation following repeated cutaneous application of MDEA during pregnancy. In addition, maternal toxicity was also present as anemia in dams receiving 1000 mg/kg/day. Despite maternal toxicity, there was no evidence of developmental effects. MDEA was not genotoxic when tested in the Salmonella/microsome reverse gene mutation test, the CHO/HGPRT forward gene mutation test, a sister chromatid exchange test in cultured CHO cells, and an in vivo peripheral blood micronucleus test in mice.
