The science of soap – here’s how it kills the coronavirus

Alcohol-based disinfectants are also effective, but soap is a highly efficient way of killing the virus when it’s on your skin

iruses can be active outside the body for hours, even days. Disinfectants, liquids, wipes, gels and creams containing alcohol are all useful at getting rid of them – but they are not quite as good as normal soap.

With Italy in lockdown, fear over coronavirus is natural but we must not be alarmist Gaby Hinsliff Gaby Hinsliff Read more When I shared the information above using Twitter, it went viral. I think I have worked out why. Health authorities have been giving us two messages: once you have the virus there are no drugs that can kill it or help you get rid of it. But also, wash your hands to stop the virus spreading. This seems odd. You can’t, even for a million dollars, get a drug for the coronavirus – but your grandmother’s bar of soap kills the virus.

So why does soap work so well on the Sars-CoV-2, the coronavirus and indeed most viruses? The short story: because the virus is a self-assembled nanoparticle in which the weakest link is the lipid (fatty) bilayer. Soap dissolves the fat membrane and the virus falls apart like a house of cards and dies – or rather, we should say it becomes inactive as viruses aren’t really alive.

The slightly longer story is that most viruses consist of three key building blocks: ribonucleic acid (RNA), proteins and lipids. A virus-infected cell makes lots of these building blocks, which then spontaneously self-assemble to form the virus. Critically, there are no strong covalent bonds holding these units together, which means you do not necessarily need harsh chemicals to split those units apart. When an infected cell dies, all these new

Yep. If a soap maker claims otherwise they fall into FDA regulation territory. Drug claim or cosmetic claim. And yes they can get in big trouble for that.

Several reports have shown hospitals using Dawn for hand washing.

This can’t be. Only alcohol wipes and liquid matter! /snark

We’ve had no soap, detergent, or bleach hoarding articles because there has been no such behavior and no such “monopoly” “hurting” us.

I had my training as a nurse in the 90’s. How I wish I had done my training in the 60’s or 70’s! Nurses trained back then, and earlier, had things like DON’T TOUCH YOUR FACE!, drilled into them by no-nonsense instructors, who like old fashioned drill sergeants, brooked no laxity, and penalized offenders by giving them extra duties, etc., so students would remember the lesson. Yes, we were taught not to touch our faces, but I know it didn’t stick as well as it did to the old-time nurses. Fortunately, good hand washing stuck like glue to me.

I read that the 70% alcohol is more effective at killing germs than the 91%.

Counterintuitive, but true.

Gen-Z is the least likely to die of corona virus.
Gen-Z eats tide pods.
Thus, tide pods protect you from the corona virus.

Glycol percentage in antifreeze is similar.

I’ve read the same thing. The recipe I saw had you dilute the alcohol down to a final percentage of around 80% using water.

I think that the key is lye, but someone else should be able to say that more authoritatively.

Dawn dish detergent dissolves fat/grease and probably works pretty good as a hand soap for this, but it will dry your hands out quickly.

But it does make reloadable brass cartridges shine like new. That alone is worth the price of admission.

Does anybody know if liquid soap works as well? Thanks

This past Friday I had a CT scan at a large hospital in nearby Olympia, where you have to sign in at the radiology desk via touch screen computer. No human there, just the monitor and a big jug of hand sanitizer. Rather ironic, I muttered aloud. Spoke to three different people while waiting, all pro- Trump.
I washed my hands about five times during my visit, went home and ran thru the sheep dip then showered twice.

"... is there a common ingredient in soap ..."

Yes. The common ingredient is SOAP.

Here's my simplistic and perhaps not completely accurate description.

Water consists of molecules of H2O. That is, two hyrogen atoms bonded to an oxygen atom. The two hydrogen atoms do not position themselves on opposite sides of the oxygen but, instead, are closer to each other. That results in a polar molecule that has a positive end and a negative end.

Oils and fats tend to be non-polar molecules; that is there is no positive or negative end. Such molecules can be sticky and resist being washed away by water.

Soap is a more complicated molecule and has a polar end and a non-polar end. The polar end can stick to oil. The non-polar end can allow the molecule to be mixed with the water. Basically, the soap molecule sticks to the oil and allows itself to be washed away by the water, taking the oil with it.

The reason that soap can kill viruses is because part of the virus is really an oil. The soap disrupts the structure of the virus and disables it permanently.

I seem to recall that at one time nurses were told to keep their nails short with clear polish only if any. I don’t think that rule is enforced anymore.

Lye more correctly sodium hydroxide or potassium hydroxide is used in soap making. You cannot make soap without it. Basically soap is a salt made by combining an acid (the fatty acids found in fats or oils) with a base (NAOH or KOH). That is why if you look on a bar of soap you will see ingredients such as sodium palmate, sodium cocoate, and sodium olivate. This tells you that palm, coconut,and olive oil have been saponified by the use of sodium hydroxide.

I was thinking about making a soap smoothie.
3/4 water, plain yogurt, 1/4 cup of blueberries and soap.

You could just eat cilantro. It tastes like soap.
