Isopropyl alcohol, often called IPA or isopropanol, is similar in function and structure to ethanol. It evaporates at a similar rate and destroys bacterial and viral cells by the same mechanism. However, it is not as effective at dehydrating living tissue and so is a better solution for disinfecting skin than ethanol. Isopropyl alcohol is often used as an antiseptic for this reason
CDC: https://www.cdc.gov/infectioncontrol/guidelines/disinfection/disinfection-methods/chemical.html Ethyl alcohol, at concentrations of 60%–80%, is a potent virucidal agent inactivating all of the lipophilic viruses (e.g., herpes, vaccinia, and influenza virus) and many hydrophilic viruses (e.g., adenovirus, enterovirus, rhinovirus, and rotaviruses but not hepatitis A virus (HAV) 58 or poliovirus) 49. Isopropyl alcohol is not active against the nonlipid enteroviruses but is fully active against the lipid viruses 72. 冠状病毒是non lipid virus。

如果是，北美的酒精不是乙醇都是异丙醇？
对病毒而言，效果没有乙醇好
原来如此，谢谢
所以说不管用？
对哒！
其实你注意了擦了就很好了
这是个probability的事，90%和99%的差别，即使没买到99%杀毒概率的，拿90%的擦两次不就可以了
酸啊酒精类的，70%到99%，民用的拿来擦擦都可以的，无需那么紧张的
并不是的，很多时候是专项专用，还是需要知道背后知识的。
杀冠状病毒，IPA不好用。
nice
那就说明冠状病毒在体外不是很顽固，醇类变性剂效果不错。
因为CDC提过IPA对nonlipid virus效果打折扣
