毒理性
识别和使用：异冰片是一种白色固体。它被用作食品和饮料中的香料成分。它也用于香水制造和化学酯的制备。人体研究：在一项人体最大量测试中，没有观察到10%异冰片在凡士林中引起的敏感性反应。在0.016%至0.08%的浓度范围内，异冰片对人细胞系测试时没有表现出显著的细胞毒性。动物研究：在0.016%至0.08%的浓度范围内，异冰片对猴细胞系测试时没有表现出显著的细胞毒性。交叉参考化学品l-冰片和异冰片酯进行了遗传毒性、重复剂量毒性、发育和生殖毒性的评估。在针对大鼠进行的13周亚慢性毒性研究中，异冰片酯的无观察到有害作用水平（NOEL）确定为15 mg/kg/天，基于尿细胞排出的增加。异冰片酯在亲代生殖毒性的无观察到有害作用水平（NOAEL）确定为300 mg/kg/天。l-冰片在Ames试验中不是致突变剂。异冰片在Bluescreen试验中评估了其遗传毒性潜力，发现在有和没有代谢激活的情况下，异冰片对遗传毒性和细胞毒性均为阴性。
IDENTIFICATION AND USE: Isoborneol is a white solid. It is used as a flavor ingredient in food and beverages. It is also used in perfumery and in preparation of chemical esters.HUMAN STUDIES: In a human maximization test, no reactions indicative of sensitization were observed with 10% isoborneol in petrolatum. Isoborneol did not exhibit significant cytotoxicity at concentrations ranging between 0.016% and 0.08% when tested against human cell lines. ANIMAL STUDIES: Isoborneol did not exhibit significant cytotoxicity at concentrations ranging between 0.016% and 0.08% when tested against monkey cell lines. Read across chemicals l-borneol and isobornyl acetate were evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity. In the13-week subchronic toxicity study for isobornyl acetate conducted in rats the NOEL was determined to be 15 mg/kg/day, based on increased urinary cell excretion.The NOAEL for reproductive toxicity in the parental generation was determined to be 300 mg/kg/day for isobornyl acetate. l-borneol was not mutagenic in the Ames test. Isoborneol, was assessed for genotoxic potential in the Bluescreen assay and was found negative for genotoxicity and cytotoxicity in the presence and absence of metabolic activation.
