As a disinfectant, the higher the concentration of alcohol, the less effective it is at killing pathogens. … Coagulation of surface proteins proceeds at a slower pace, thereby allowing the alcohol to enter the cell.
What is 99% isopropyl alcohol used for?
99% isopropyl alcohol is used: To clean surfaces, both alone and as a component of a general-purpose cleaner, or as a solvent. 99% isopropyl alcohol has the benefit of being non-corrosive to metals or plastics, so it can be used widely, on all surfaces, and won’t leave smears, even on glass or screens.

Is hydrogen peroxide isopropyl?
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. … The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.
What is the difference between hand sanitizer and rubbing alcohol?
Rubbing alcohol and hand sanitizer are important chemicals in cleaning surfaces. The key difference between rubbing alcohol and hand sanitizer is that rubbing alcohol is denatured ethanol with other components, whereas hand sanitizers are solutions containing a high percentage of alcohol in water.
What is true about isopropyl alcohol?
Isopropyl alcohol is mixed with water for use as a rubbing-alcohol antiseptic. It is also used in aftershave lotions, hand lotions, and other cosmetics. … Added to wet gas, it helps to prevent separation and freezing of a water layer.
