Answer:
WHO recommended 75% IPA for hand sanitizers. Earlier recommended IPA percentage was 65-70%. When the IPA percentage goes up, water content goes down. It means the evaporation rate of IPA becomes high. Therefore, the contact time becomes low. I conducted a lab trial with two concentrations of IPA. 65% and 70%. 65% IPA containing hand sanitizer gave a good result than 70% IPA hand sanitizer. In this case, will 75% provide a good result?
