11. Washing Hands In Cold Water Works As Well As Hot Against Germs
Mon Mar 2, 2020, 08:20 AM
Mar 2020
https://time.com/4800412/wash-hands-cold-water/

Good news for anyone planning on getting their hands dirty this summer: Washing them with cold or lukewarm water will work just as well as hot water to remove bacteria, according to a new study published in the Journal of Food Protection.

In handwashing experiments with 21 volunteers, Rutgers University researchers found no significant difference in cleaning power between water that was 60, 79 or 100 degrees Fahrenheit. They also found that lathering hands for just 10 seconds was sufficient to remove germs.

Everyone in the study had high levels of a harmless strain of E. coli bacteria applied to their hands and were then asked to wash them in a variety of scenarios: using cold, warm or hot water; using between half a milliliter and 2 milliliters of soap; and washing for various lengths of time, between 5 and 40 seconds. They repeated these tests several times over six months.

Just buy 70% alcohol, a pack of disposable dry cloth or paper wipes, and a good common hand lotion. Wipe your hands with an alcohol moistened wipe, let them air dry a few seconds, then put lotion on your hands.

People are really stupid to pay over a hundred dollars for what they can do better with spending maybe $10.

i regard it as a credit to our efforts that Y2K passed quietly and is now widely regarded as techies "crying wolf" or some such.

the COVID-19 outbreak strikes me as far different because the time for effective containment ended prior to discovery of the problem. it's like if Y2K occurred but no one bothered to prepare at all. we are in the middle of a truly amazing clusterfuck, make no mistake.

The same applies to hand sanitation, bleach-based products are far more effective than hand sanitizer.

Most hand sanitizers must remain wet for 5 minutes to be partially effective.

Most people who use it, let it dry in seconds.

I would likely go up a little on your bleach concentration and use distilled water instead of tap water. But, a bleach solution at an adequate concentration should be effective, it just stinks and the stink lingers. I would use rubbing alcohol instead.

What about the study finding more norovirus outbreaks with use of hand sanitizers?

"This study does not change my routine recommendation that people should use a hand sanitizer," Glatt says. He sees them as especially useful when water is not available.

In the study, published in the American Journal of Infection Control, CDC researchers looked at the use of hand sanitizers by the staff in 91 long-term care facilities. In those where the staff were equally or more likely to use the hand sanitizers over soap and water for routine hand hygiene, the chance of an outbreak was nearly six times greater.

"It's one study,” says Glatt.

More research is needed, he and other experts say.

So, is hand washing better than hand sanitizers to prevent infection spread?

Both are important, say Glatt and Brian Sansoni, spokesman for the American Cleaning Institute.

"Soap and water are number one," says Sansoni. "Hand sanitizers are a very effective additional tool."

The sanitizers are meant to supplement, not replace, good old-fashioned soap and water washing, Sansoni says.

The CDC agrees. It says that for norovirus, washing hands is your best prevention, especially after using the bathroom, changing a diaper, and before eating and doing food prep. Sanitizers may help, but “they are not a substitute for washing with soap and water.”

Tue Mar 3, 2020, 02:14 PM
Mar 2020

that is where the discussion about hand sanitizers started.

Personally, if I was out and about where I could not wash my hands, like I stated, I would use rubbing alcohol followed by hand lotion, making sure that I got under my nails when wiping with the alcohol wipe.

Rubbing alcohol is generally around 70-73%. If people want a more powerful alcohol, they can use the 90-91% stuff or EverClear (100% alcohol). If they are concerned oil removal from the skin (defatting) they can make a bottle of half rubbing alcohol and half the more powerful stuff. Regardless, they should follow with a common hand lotion, ones that have cinnamon or lavender oil in them would be excellent.

But if people can, they should wash their hands, using a good anti-bacteria soap, like experts recommend they do when they can.

64. Sorry BA, But No
Wed Mar 4, 2020, 08:52 AM

A few reasons.
The 30% water raises the vapor pressure of a thin film of liquid making it stay there longer as evaporation slows.
More importantly, that much water raises the surface tension of the mixture exponentially. So, when that is swabbed or wiped, more actually sticks to the surface. Microscopic layer, but then we're talking microbes.
Third, in the presence of liquid that isn't water, the microbes slows activity. So, the denaturing effect of the alcohol slows.
By having that much water, the microbes' respiration does not slow, making the "poisoning" more efficient.
Now, the 3rd one admittedly is less relevant with viruses than bacteria, but the micro folks are always concerned with both, plus mold and fungi.
In actuality, compounds with labile chlorine are more effective because the mechanism is more damaging to the tiny world.
The active ingredient in things like Clorox or Lysol wipes are exactly that, and that is what I'd use.
My advantage is that I have 2 quart jars of the active ingredient at 40% in water/isopropanol in my garage.
That'll last us 10 years.

63. "Why Is 70% the Most Effective Concentration of Isopropyl Alcohol for Disinfection?"
Tue Mar 3, 2020, 05:55 PM
Mar 2020

From https://blog.gotopac.com/2017/05/15/why-is-70-isopropyl-alcohol-ipa-a-better-disinfectant-than-99-isopropanol-and-what-is-ipa-used-for/


Why Is 70% the Most Effective Concentration of Isopropyl Alcohol for Disinfection?

[...]

Isopropyl alcohol, particularly in solutions between 60% and 90% alcohol with 10 – 40% purified water, is rapidly antimicrobial against bacteria, fungi, and viruses. Once alcohol concentrations drop below 50%, usefulness for disinfection drops sharply. Notably, higher concentrations of alcohol don’t generate more desirable bactericidal, virucidal, or fungicidal properties.

The presence of water is a crucial factor in destroying or inhibiting the growth of pathogenic microorganisms with isopropyl alcohol. Water acts as a catalyst and plays a key role in denaturing the proteins of vegetative cell membranes. 70% IPA solutions penetrate the cell wall more completely which permeates the entire cell, coagulates all proteins, and therefore the microorganism dies. Extra water content slows evaporation, therefore increasing surface contact time and enhancing effectiveness. Isopropyl alcohol concentrations over 91% coagulate proteins instantly. Consequently, a protective layer is created which protects other proteins from further coagulation.

Solutions > 91% IPA may kill some bacteria, but require longer contact times for disinfection, and enable spores to lie in a dormant state without being killed. A 50% isopropyl alcohol solution kills Staphylococcus Aureus in less than 10 seconds (pg. 238), yet a 90% solution with a contact time of over two hours is ineffective. Some disinfectants will kill spores with exposures times that exceed 3-12 hours, which are classified as chemical sterilants. So why do higher alcohol solutions yield fewer results for bactericidal and antimicrobial outcomes?

Where did you see 1 tablespoon (3 teaspoons) per gallon recommended?

BTW, they recommend more than 1 tablespoon/gallon, for cleaning some surfaces. They list different concentrations for different types of surfaces:

Purell Hand Sanitizer (ethyl alcohol), Purell Food surface Sanitizer (ethyl alcohol) and an institutional sanitizer (ammonia) which is listed specifically to be effective against Coronavirus (ATCC VR-740, Strain 229E). My take is that dilute bleach or ammonia are the probably most effective and the most practical. The crucial part is to thoroughly wet the area and to leave the solution on for ten minutes if possible.
