毒理性
1-丙氧基-2-丙醇在涂料、清洁剂、油墨中使用。人类暴露和毒性:无数据。动物研究:将0.1、0.01或0.005毫升滴入兔子的眼睛中会引起严重的结膜炎和弥散性轻度角膜损伤,需要3-14天才能完全解决。在室温下,吸入大量饱和蒸汽可能导致大鼠严重失去协调和麻醉。测试材料的急性口服毒性较低。在兔子的急性覆盖皮肤应用后,临床体征包括红斑、水肿、瘀血、脱皮、麻醉和眼部刺激。大体病理显示肺充血、肝脏斑驳和肾脏苍白。在大鼠中,除了1500 ppm组在母体毒性存在下观察到的后肢趾骨化减少外,没有发现与处理相关的内脏或骨骼畸形、异常或变异。在兔子中,1500 ppm观察到的母体毒性表现为显著死亡率(27.3%)、体重增加减少以及食物和水的消耗减少。妊娠参数没有显著变化,包括黄体数量、总不可活和可活着床数/窝、性别比、着床前后损失和胎儿体重。没有观察到与处理相关的内脏或骨骼畸形、异常或变异。在遗传毒性测试中,使用鼠伤寒沙门氏菌测试菌株TA98、TA100、TA1535和TA1537以及大肠杆菌测试菌株WP2ucrA,该化学物质为阴性。测试材料的浓度范围为100至5000微克/平板。在体外染色体畸变试验中,使用大鼠淋巴细胞,也被认为是阴性。
IDENTIFICATION AND USE: 1-PROPOXY-2-PROPANOL is used in coatings, cleaners, inks. HUMAN EXPOSURE AND TOXICITY: No data. ANIMAL STUDIES: Instillation of 0.1, 0.01, or 0.005 mL into the eyes of rabbits caused severe conjunctivitis and diffusely mild corneal injury, requiring 3-14 days for complete resolution. Inhalation of substantially saturated vapor evolved at room temperature under may result in severe loss of coordination and anesthesia in rats. The test material has low acute oral toxicity. Following acute covered dermal application in rabbits, clinical signs included erythema, edema, ecchymosis, desquamation, anesthesia and eye irritation. Gross pathology revealed congested lungs, mottled livers and pale kidneys. In rats there were no treatment-related visceral or skeletal malformations, anomalies or variations with the exceptions of reduced ossification of hindlimb phalanges in litters of the 1500 ppm group observed in the presence of maternal toxicity. In rabbits maternal toxicity observed at 1500 ppm was evidenced by significant mortality (27.3%), reduction in weight gain and food and water consumption. Gestational parameters exhibited no significant changes, including the number of corpora lutea, total nonviable and viable implantations/litter, sex ratio, pre or postimplantation loss, and fetal body weights. No treatment-related visceral or skeletal malformations, anomalies or variations were observed. The chemical was negative in the genotoxicity testing using Salmonella typhimurium tester strains TA98, TA100, TA1535, and TA1537 and Escherichia coli tester strain WP2ucrA. The concentrations of the test material assay ranged from 100 to 5000 ug/plate. It was also was considered to be negative in the in vitro chromosomal aberration assay utilizing rat lymphocytes.
