Abstract The COVID-19 crisis and ensuing supply chain disruptions prompted many breweries and distilleries to repurpose their facilities for the production of hand sanitizer, with the vast majority following the World Health Organization formulation (80% v/v ethanol, 1.45% v/v glycerol and 0.125% v/v hydrogen peroxide). The long term shift from bottling to canning among craft brewers left canning as the sole scalable option for many facilities to package hand sanitizer. With essential services desperate for hand sanitizer to help protect their staff, patients, and clients, many breweries moved to package these products in cans despite warnings that they are not designed to hold solutions containing high ethanol concentrations or strong oxidizers. The present study explores the resistance of ubiquitous can liners, WB Modified Epoxy and BPANI Gen 2, to WHO formulated hand sanitizer. Shelf life observations and microscopic visualization show the WB Modified Epoxy liner withstands hand sanitizer with little observable disruption at room temperature, while BPANI Gen 2 liners permit package failure and liquid leakage within 30 days. Incubation at 37 °C accelerated the rate of failure sixfold in BPANI Gen 2 lined cans versus room temperature incubation, providing a basis by which to expect an approximately 72 day shelf life for WB Modified Epoxy lined cans. Because of the inherent risk to consumers presented by these data and despite lack of clear guidance from regulatory agencies, manufacturers should strive to cease packaging hand sanitizer in cans and instead find supplies of inert non-beverage containers.

含洗手液的铝制啤酒罐的耐腐蚀性能

摘要 COVID-19 危机和随之而来的供应链中断促使许多啤酒厂和酿酒厂将其设施重新用于生产洗手液,其中绝大多数遵循世界卫生组织的配方(80% v/v 乙醇,1.45% v/v甘油和 0.125% v/v 过氧化氢)。精酿啤酒商从装瓶到罐装的长期转变使罐装成为许多设施包装洗手液的唯一可扩展选择。由于基本服务迫切需要洗手液来帮助保护他们的员工、患者和客户,许多啤酒厂将这些产品包装在罐中,尽管警告说这些产品并非旨在容纳含有高浓度乙醇或强氧化剂的溶液。本研究探讨了普遍存在的罐头衬垫、WB 改性环氧树脂和 BPANI Gen 2 的抵抗力,世卫组织配制的洗手液。保质期观察和显微可视化显示,WB 改性环氧树脂内衬可耐受洗手液,在室温下几乎没有可观察到的中断,而 BPANI Gen 2 内衬允许在 30 天内出现包装损坏和液体泄漏。与室温孵育相比,在 37 °C 下孵育将 BPANI Gen 2 内衬罐的失败率提高了六倍,这为预计 WB 改性环氧内衬罐的保质期约为 72 天提供了基础。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。保质期观察和显微可视化显示 WB 改性环氧树脂内衬可耐受洗手液,在室温下几乎没有可观察到的中断,而 BPANI Gen 2 内衬允许在 30 天内出现包装损坏和液体泄漏。与室温孵育相比,在 37 °C 下孵育将 BPANI Gen 2 内衬罐的失败率提高了六倍,这为预计 WB 改性环氧内衬罐的保质期约为 72 天提供了基础。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。保质期观察和显微可视化显示,WB 改性环氧树脂内衬可耐受洗手液,在室温下几乎没有可观察到的中断,而 BPANI Gen 2 内衬允许在 30 天内出现包装损坏和液体泄漏。与室温孵育相比,在 37 °C 下孵育将 BPANI Gen 2 内衬罐的失败率提高了六倍,这为预计 WB 改性环氧内衬罐的保质期约为 72 天提供了基础。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。而 BPANI Gen 2 内衬允许在 30 天内出现包装故障和液体泄漏。与室温孵育相比,在 37 °C 下孵育将 BPANI Gen 2 内衬罐的失败率提高了六倍,这为预计 WB 改性环氧内衬罐的保质期约为 72 天提供了基础。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。而 BPANI Gen 2 内衬允许在 30 天内出现包装故障和液体泄漏。与室温孵育相比,在 37 °C 下孵育将 BPANI Gen 2 内衬罐的失败率提高了六倍,这为预计 WB 改性环氧内衬罐的保质期约为 72 天提供了基础。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。WB 改性环氧内衬罐的保质期约为 72 天。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。WB 改性环氧内衬罐的保质期约为 72 天。由于这些数据给消费者带来了固有风险,并且尽管监管机构缺乏明确的指导,但制造商应努力停止将洗手液包装在罐中,转而寻找惰性非饮料容器的供应。
