Does isopropyl alcohol kill bacteria and germs?
Isopropyl Alcohol (particularly 60 to 90 percent) is antimicrobial against viruses, fungi and bacteria. It kills microorganisms such as bacteria, germs and fungi or halts their growth, specifically the spread of germs. Isopropyl Alcohol kilss 99.99% of germs in under 30 seconds making it an in-demand and popular sterilisation solution.
What’s the difference between 100% and 70% isopropyl alcohol?
The percentage of IPA correlates to the ration of purified water it is diluted with. Pure 100% IPA is not diluted with any water; common formulas include a ratio of 10 – 40% purified water.
Does 70% rubbing alcohol kill germs?
Yes. Purified water plays an important role in the effectiveness of Isopropyl Alcohol (IPA) as it delays the evaporation rate and therefore increasing the time it remains effective on a surface. 70 percent IPA solutions are most effective in fully penetrating the cell wall, killing the organism. This slightly diluted formula helps to destroy the harmful properties of common pathogens and microorganisms.
What is 70% isopropyl alcohol used for?
70% IPA is the most commonly used form of this solvent. It is used to sanitise areas where germs may be present including household surfaces, beauty salons and hospitals.
​Can 70% Isopropyl Alcohol be used as a Disinfectant?
Yes, it is the 70% diluted solution that can act as a disinfectant because the water helps keep the solution on the surface for longer allowing it to penetrate the cell wall of the organism.
What is 99%-100% isopropyl alcohol used for?
The highly concentrated version of IPA is much less commonly used than 70% IPA. Most often, 99% IPA is used in industrial application or in scientific research, on products that are sensitive to water.
How do you dilute isopropyl alcohol to 70 percent?
Although pure isopropyl alcohol can be diluted, we suggest purchasing a premixed 70% IPA solution. Not only is 70% IPA less expensive, it is also professionally pre-diluted, therefore removing any potential margin of error for mixing.
