It has been reported that rubbing alcohol (70%) is effective for disinfecting skin such as hands *. However, it is said that there is no effect unless it exceeds 70%. In addition, too high alcohol concentration may cause rough skin, so it is important to use at an appropriate concentration.
*The standard of the Center for Disease Control and Prevention (CDC) is 60% or more. The Japanese Ministry of Health, Labor and Welfare recommends 70% or more. Also, CDC recommends 70% or more for disinfecting the surface of objects.

If you have a PAL-COVID-19, you can check the concentration of the diluted liquid, so it is also possible to dilute it in a proportion.
※If you do not have purified water, you can substitute water (tap water or mineral water).
What is the difference between absolute ethanol, ethanol, and disinfecting ethanol?
The concentration of ethanol contained in each is different.
Disinfecting ethanol is used for disinfection, because the disinfecting effect is best when the ethanol concentration is around 80%.
