Is that what you want to put into your, or your children's hands???
Extracts of Q&A from Pfizer's website:
Is there a problem with Purell® instant hand sanitizer staining floors?
Because alcohol is a solvent (Purell® Instant Hand Sanitizer contains 62% Ethyl Alcohol), it can dissolve floor wax and leave a dull or discolored spot if dripped on the floor. In certain situations, product may be "splashed" onto the floor from the user's hands as it is being rubbed in.
If Purell can dissolve commercial floor wax, imagine what it will do to the lipids in your skin cells.
The recommendation of the CDC is that recurrent use of alcohol based gel hand sanitizers is not recommended without adequate hand washing between uses. The reason for this is that gels leave a biofilm on skin surfaces that trap dirt and potentially pathogenic organisms. Effectiveness decreases with added use and alcohol based products are ineffective with the third use without washing your hands.
Since Purell and other alcohol gel products have no residual germ killing protection, you will pick potentially pathogenic organisms as soon as the alcohol dries. For some protection, alcohol based hand sanitizer need to be used every 5 minutes when in a dirty environment. Remember, studies have shown that with the third use, alcohol gel based products without a hand wash with soap and water are ineffective in killing re-colonized germs. Soil also inactivates the effects of alcohol.
Purell will not work in the presence organic soil (dirt or grease). This is why they tell you to wash your hands often.
