Greetings to everyone.
This query is related to the composition of alcohol in alcohol based hand sanitizers. Organizations like CDC,EPA,WHO recommends alcohol based sanitizers having 60-95% concentration of alcohol. However it mentions nowhere whether the recommended concentration should be weight/weight or volume/volume or weight/volume. Secondly, which grade of ethanol is required ? Can we use Ethanol 96% which is used in perfumes industries ?
Your wise response is eagerly awaited.
