If I keep using 99% abacterial hand soap would I be breeding super bacterias?

What happens to all the 1%'s that breed?If I keep using 99% abacterial hand soap would I be breeding super bacterias?
There aren't all that many studies showing that triclosan is causing resistance over a short period of time. However many scientists are concerned that triclosan may be responsible for resistance to other anti-microbials. Basically, some resistance could occur, but the bigger concern is cross-resistance, and there are a limited amount of studies investigating this situation.If I keep using 99% abacterial hand soap would I be breeding super bacterias?
Yes. This has been a real concern of many bacteriologists for awhile. The 1% is what the soap does not treat, and those tend to be viruses such as (i think) hep C. This also relates with overuse of prescription antibacs that can become useless against certain strains (like the influenza virus). My best suggestion is to use normal soap. Plain soap kills and removes a massive number of germs and bacteria that do not require antibacterial versions. Unless you are in the medical professions. Then for goodness sake use those bug killers and have pride.
antibacterial gels are no more effective than soap and water. alcohol is not considered a disinfecting agent since you need at least 70% alcohol w/ a 10 minute contact time--the alcohol will evaporate by then.





furthermore that 99%, 99.9%, and et cetera labeling is just that, labeling purposes; there are different levels of cleaning: cleaning-removal of gross dirt, sanitation- cleaning such that pathogens are at an acceptable public health standard (99%), disinfection-cleaning such that more pathogens are elliminated (99.9%), and sterilization-cleaning such that there are no pathogens...or something like that. i don't really remember.
Make sure that the hand soap effectively kills bacterial. Many manufacturers state that their soap kills ';99% of all bacteria'; but the alcohol concentration isn't high enough to do that. If the soap is effective, then no super bacteria will be created since they'll die. The 1% that isn't affected by the soap in the first place won't get any stronger. However, if you are using ineffective soap, the bacteria won't die and will get stronger...
