What proof alcohol is disinfectant?
The Centers for Disease Control and Prevention (CDC) recommends an alcohol concentration of between 60 and 90 percent for disinfection purposes.
For example, a bactericide is an agent that kills bacteria. Isopropyl alcohol is excluded from classification as a high-level disinfectant because of its inability to eradicate bacterial spores and hydrophilic viruses such as polio.
Mix 2 parts rubbing alcohol to 1 part water in a spray bottle, and use it to disinfect points of contact and other germy areas. You can even use it directly on a cotton pad to clean your earring posts, thermometers, and any other personal items.
70% isopropyl alcohol is most commonly used disinfectant in pharmaceutical industries. The important thing is that only 70% solution of isopropyl alcohol acts as a disinfectant killing all surface microorganisms. It is used to disinfect hands and equipment surface in pharmaceuticals.
What's the most effective alcohol concentration solution? A concentration of about 70 percent isopropanol or ethyl alcohol is most effective for killing germs. In general, solutions with 60 to 90 percent water tend to be more effective at killing viruses than solutions with concentrations outside this range.
You can use alcohol as a disinfectant for items like scissors, thermometers, and other surfaces. However, alcohol isn't always reliable enough as a hospital-grade disinfectant. It can also damage the protective coating on some items, such as plastic tiles or glasses lenses.
While it is generally okay to use it at the 70/30 ratio, many detailers prefer to dilute it down to a 50/50 (Alcohol to Distilled Water) ratio for optimal results.
It is a commercially available product that mainly is found as a 70% solution in rubbing alcohol and hand sanitizers. Unlike the other toxic alcohols, isopropanol rarely causes death and is associated with ketosis without acidosis. Treatment of isopropanol ingestions typically consists of supportive therapy.
While 70% isopropyl alcohol makes a very effective disinfectant, the more concentrated version of 91% isopropyl alcohol also has some incredibly beneficial uses. This liquid can also be used to clean and disinfect surfaces, and it's safe to use on skin too.
Don't Clean Certain Surfaces With Rubbing Alcohol
Avoid rubbing alcohol on painted, shellacked, lacquered, or varnished surfaces, including treated wood.
Can I use 70 isopropyl alcohol to clean wound?
Clean With Hydrogen Peroxide or Alcohol? FALSE. Using hydrogen peroxide or rubbing alcohol to clean an injury can actually harm the tissue and delay healing. The best way to clean a minor wound is with cool running water and mild soap.
The main difference between isopropyl alcohol and rubbing alcohol is the concentration. The concentration of isopropyl alcohol is 100%, while the concentration of rubbing alcohol is less because of the addition of water. Otherwise, the two liquids have similar properties. They are antibacterial and antiseptic.
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%.
For clarification there is no difference whatsoever. They are the same chemical. Unfortunately there are many different naming conventions, this does lead to some confusion. So look for the two commonly used names Isopropanol Alcohol 70% or Isopropyl Alcohol 70%.
The 100% isopropyl alcohol coagulates the proteins instantly by creating a protein layer that protects the other proteins from further coagulation. Due to this microbes are not killed but remains in dormant stage.
While 70% isopropyl alcohol makes a very effective disinfectant, the more concentrated version of 91% isopropyl alcohol also has some incredibly beneficial uses. This liquid can also be used to clean and disinfect surfaces, and it's safe to use on skin too.

For disinfecting in pharmaceutical labs, hospitals, and other medical locations. Alcohol is well known for its disinfectant properties, but solutions under 50% significantly lose their effectiveness. 99% isopropyl alcohol is so effective it is suitable for medical and lab-grade applications.
When 40% alcohol (the same concentration as vodka) was used the effect on inhibiting the growth of these microorganisms was much greater when applied over 15 minutes compared to six minutes. It was determined that 40% alcohol had some ability to kill oral bacteria with an exposure time of at least one minute.
