摘要

评估1,1-二氧基庚烷的遗传毒性、重复剂量毒性、生殖毒性、局部呼吸毒性、光刺激/光致敏性、皮肤致敏性和环境安全性。读取类似物辛烷二甲基缩醛（CAS # 10022-28-3）的数据表明，1,1-二氧基庚烷预计不具有遗传毒性。使用Cramer I类材料的毒理学关注阈值（TTC）评估了重复剂量，生殖和局部呼吸毒性终点，暴露于1,1-二氧基庚烷低于TTC（分别为0.03 mg/kg/day， 0.03 mg/kg/day和1.4 mg/day）。采用非反应性材料的皮肤致敏阈值（DST）（900 μg/cm2）完成皮肤致敏终点；暴露在夏时制之下。根据紫外/可见（UV/Vis）光谱评估光刺激/光致敏性终点；1,1-二氧基庚烷不具有光刺激性/光致敏性。评估环境终点；根据国际香料协会（IFRA）环境标准，1,1-二氧基庚烷被发现不具有持久性、生物蓄积性和毒性（PBT），其风险商数基于其在欧洲和北美的当前使用量（VoU）（即预测环境浓度/预测无影响浓度[PEC/PNEC]）为<；1。

Update to RIFM fragrance ingredient safety assessment, 1,1-diethoxyheptane, CAS Registry Number 688-82-4

1,1-Diethoxyheptane was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, photoirritation/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog octanal dimethyl acetal (CAS # 10022-28-3) show that 1,1-diethoxyheptane is not expected to be genotoxic. The repeated dose, reproductive, and local respiratory toxicity endpoints were evaluated using the Threshold of Toxicological Concern (TTC) for a Cramer Class I material, and the exposure to 1,1-diethoxyheptane is below the TTC (0.03 mg/kg/day, 0.03 mg/kg/day, and 1.4 mg/day, respectively). The skin sensitization endpoint was completed using the Dermal Sensitization Threshold (DST) for non-reactive materials (900 μg/cm²); exposure is below the DST. The photoirritation/photoallergenicity endpoints were evaluated based on ultraviolet/visible (UV/Vis) spectra; 1,1-diethoxyheptane is not expected to be photoirritating/photoallergenic. The environmental endpoints were evaluated; 1,1-diethoxyheptane was found not to be Persistent, Bioaccumulative, and Toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use (VoU) in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.

期刊介绍： Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs. The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following: -Adverse physiological/biochemical, or pathological changes induced by specific defined substances -New techniques for assessing potential toxicity, including molecular biology -Mechanisms underlying toxic phenomena -Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability. Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
