Is rubbing alcohol a disinfectant?
Isopropyl alcohol, often called IPA or Isopropanol, is similar in function and structure to ethanol. It evaporates at a similar rate and destroys bacterial and viral cells by the same mechanism. However, it is not as effective at dehydrating living tissue and so is a better solution for disinfecting skin than ethanol.
The alcohol antibacterial preparations are highly effective at killing bacteria and viruses, but only if there is direct contact of alcohol with the microorganisms. So, if there is a lot of dirt on the hands, the antibacterial hand gel may not reach the microorganisms under the dirt.

- The answer is that while bacteria do not acquire a DNA-based resistance to alcohol, the way that they do to antibiotics which are then transfered between different bacteria in the environment, bacteria can survive death by alcohol and not only survive but "persist" or stay viable but latent on a surface until they are
- Not usually. Alcohol-based hand sanitizers are not the problem. The CDC recommends using sanitizers (like Purell) that contain at least 60% alcohol, which are the same kind used in hospitals. Because alcohol attacks all proteins in the bacteria, not just one, the bacteria can't develop resistance.
Rubbing alcohol refers to either isopropyl alcohol (propan-2-ol) or ethanol based liquids, or the comparable British Pharmacopoeia defined surgical spirit, with isopropyl alcohol products being the most widely available. They are liquids used primarily as a topical antiseptic.
- Ingredient Watch List: Isopropyl Alcohol, the Drying and Harsh Disinfectant You Don't Need. Isopropyl alcohol, also known as isopropanol, is a harmful and unnecessary ingredient used in many skin care products. Not only does it have no nourishing qualities, it can lead to dry, flaky skin and actually exacerbate acne.
- An antiseptic is used on living tissues and cells to destroy any types of infections which may be living on the tissue. Disinfectants are meant to destroy microorganisms which can infect nonliving objects. Common antiseptics include mouthwash, and yeast infection treatment creams.
- The expiration date on medicines and related drugs (of which rubbing alcohol is one of them) usually pertains to the fact the become less effective over time. It isn't bad, it just isn't as potent anymore. Rubbing alcohol evaporates. If it's pure, that should be about it.
