Is 50% alcohol a disinfectant?

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.

Which is a better disinfectant ethyl alcohol or isopropyl alcohol?

For disinfecting surfaces, ethanol and isopropyl alcohol are nearly equally efficient. Ethanol may be used in purely surface-cleaning applications, but isopropyl alcohol can also double as antiseptic and is often used in hospitals.

70% IPA solutions penetrate the cell wall more completely which permeates the entire cell, coagulates all proteins, and therefore the microorganism dies. Extra water content slows evaporation, therefore increasing surface contact time and enhancing effectiveness.

Can whiskey kill bacteria?

A study published in the Annals of Microbiology has found that whiskey kills ice bacteria more effectively than vodka. … They found that while alcohol, CO2, and acidic pH levels consistently reduced the presence of bacteria, whiskey was the only liquid that eliminated all 4 strains of bacteria in the ice.
