Ethanol is widely used for general surface disinfecting and has reported biocidal efficacy against bacteria, fungi and viruses in the concentration range of 50%–90% . Higher concentrations of ethanol are required to kill fungal spores than bacteria, which show a maximum kill efficacy of 70% ethanol .
Will isopropyl alcohol kill fungus?
Rubbing alcohol can be effective in killing the fungus that causes toenail infections and athletes foot. However, it will usually only eliminate surface-level bacteria in the earliest stages of an infection. If some fungus remains in and around the toenail, an infection can recur.
What does alcohol 70% mean?
Isopropyl alcohol 70 percent, or isopropyl alcohol 99 percent diluted to 70 percent with purified water, kills organisms by denaturing their proteins. A 70 percent isopropyl alcohol solution dissolves their lipids and is effective against most bacteria and fungi and many viruses.
Why is 70 alcohol used for sterilization not 100?
Pure alcohol coagulates protein in contact. If 70 percent of alcohol is poured to a single celled organism, the diluted alcohol also coagulates the protein, but at a slower rate, so that it penetrates all the way through the cell before coagulation can block it. Then the entire cell is coagulated and the organism dies.
Can I use Everclear instead of rubbing alcohol?
If you are having trouble finding rubbing alcohol, then you can substitute a white ethanol like vodka or everclear. Remember, proof and percentage of alcohol are different.
