The rubbing alcohol you buy at the drugstore is a mixture of isopropyl alcohol and water. It comes in different strengths, ranging from 50\% to 90\% isopropyl alcohol. “Lower concentrations aren’t as good at killing germs,” Dr. Beers says.

What is the difference between 50 and 70 rubbing alcohol?

Even though you may think the higher concentration is more effective, experts say 70\% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria. The disinfecting power of rubbing alcohol drops at concentrations higher than 80\%-85\%.

How do you make 70 alcohol out of 96?

For your example, 70/96 = 0.729, multiply this result by the volume you want; for example 100 ml = 72.9 ml of original solution, made up to 100 ml. Mix 365 ml of 96\% ethanol with 135 ml of water.

Is 70 percent alcohol better for disinfection than 91 percent?

But according to microbiology, 70 percent alcohol is probably more effective than 91 percent for disinfecting —depending on what kind of germs you’re trying to kill. Here’s why a lower-percentage alcohol might be a better weapon against germs:

What is the percentage of alcohol in hand sanitizer?

If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60\% alcohol. Why? Many studies have found that sanitizers with an alcohol concentration between 60–95\% are more effective at killing germs than those with a lower alcohol concentration or non-alcohol-based hand sanitizers 16, 20.

What happens when you pour 70\% alcohol on a cell?

Under the favorable conditions the cell would then begin to function. While on other hand, 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.
