Which is a better disinfectant ethyl alcohol or isopropyl alcohol?

What alcohol is best for disinfecting?
Isopropyl alcohol, particularly in solutions between 60% and 90% alcohol with 10 – 40% purified water, is rapidly antimicrobial against bacteria, fungi, and viruses. Once alcohol concentrations drop below 50%, usefulness for disinfection drops sharply.
Is hydrogen peroxide a good disinfectant?
Hydrogen peroxide does kill germs, including most viruses and bacteria. A concentration of 3% hydrogen peroxide is an effective disinfectant typically found in stores. Hydrogen peroxide can damage some surfaces, and is a more dangerous chemical than some disinfectants, so be cautious when handling it.
What are the ingredients in Purell hand sanitizer?
Besides ethyl alcohol, it contains water, isopropyl alcohol, glycerin, carbomer, fragrance, aminomethyl propanol, propylene glycol, isopropyl myristate, and tocopheryl acetate.
Is 70 or 90 isopropyl alcohol better for disinfecting?
“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.”
Can vodka sanitize?
Vodka, like most alcohol, is a natural disinfectant. It can easily kill many germs and works in a pinch to keep wounds and even equipment clean from infection causing bacteria.

Is 50 percent alcohol good for disinfecting?
The Centers For Disease Control (CDC) recommend alcohol at a concentration of 50%-70% for use as a disinfectant and antimicrobial. Alcohol at this dilution efficiently penetrates the bacterial cell wall, disrupts the molecular confirmation, then destroys (denatures) the proteins and enzymes inside of the cell.
