How do you even do a test and find that you killed all the germs but .111% of them? The near mathematical impossibility of this makes my head hurt. Over 99.999%?

It's a liability thing, from the company's clinical trials it passed with flying colors. But their will always be an acception somewhere so they put 99.99% so they don't get sued

While I don't know exactly how they arrive at the number I would imagine it is really, really simple.

Like looking under a microscope and counting the # of living microbes in the field of vision, then extrapolating that to the entire colony.

If it kills 99.999% of germs, and you're worried about the other .111%... I'm worried about the 100.11% of germs

[Buttknuckle]

Well they probably start by hiring people to do the test that are smart enough to know that 99.999% means they killed all but 0.001%.

pretty much this. They could claim 99%, but it doesn't sound as good as 99.99%.

 

The only reason why they don't say 100%.

Now you see why I asked smart people to explain this to me.  Smh I'm bad at math.

First of all, you didn't add correctly.

Secondly, what we scientists do is conduct experiments under controlled conditions. Make a procedure to test what you want.

 

To start:

1. Make a t0, this will be your control vial with all of the bacteria living.

2. Put your sanitizer into the vial with the bacteria.

3. Let the reaction of killing the bacteria run for a certain amount of time.

4. Run your sample in a machine. Something like an HPLC will do fine for organic material. Measure the amount of difference between the protein produced by the bacteria in your t0 and your new vial with the sanitizer.

5. Divide the concentration of protein in your test vial over the concentration of protein in your t0 (control vial).

 

That is how you find if it's 99.999% effective.

Companies like to exaggerate their figures, however, and back it up with only 1 or 2 trials out of maybe 50 (made up that number).

 

Hope that helps.

you shouldn't make fun of other people if you're incapable of adding either.

Perhaps you should just check...

I got this-

100-99.999=.001

 

Boom

[Kamahl1234]

Or you know it just kills 99.9999% of germs, which is over 99.999%.

[Gunadie]

They hire unskilled illegal aliens that are in the country without a visa to count the dead and live remaining ones.

Because the under the table labor is so cheap and the germs are infinite,these huge companies wouldn't be able to do it any other way.

Expect that to change in the near future though as the germ counters may be sent back to their place of origin.

They wont be able to sub contract these services out over-seas either, so anti-bacterial soap prices are expected to soar as the labor will be significantly higher for legalized germ counters.

This is why they suggest that antibacterial soaps are not recommended anymore!

Joking aside..its actually proven they are no more effective at sanitizing than any other soap.

The gimmick is that people are actually made more aware and are washing their hands more often when the stereo-typical corporate fear mongering looms overhead.

Welcome back CanadianGuitar! Where have you been hiding? Or should I say, hibernating?

What they don't let you know is that it is killing ALL GERMS, not just the bad ones. It is literally destroying even the good germs where you use the chemical. But then it's much like why NASA tends to keep secrets about random stuff orbiting the planet, because letting it be known will cause hysteria and panic, maybe not nearly as much as finding out we've had a satelite potetially foereign to Earth orbiting use since the 50s, but you get the jist.

[Tuwtles_50B_God]

I'm pretty sure the 99.whatever% is just bs.

[Loli_Lives_Matter]

1) Liability issues

2) Scientists still debate whether or not a Virus is technically alive*, so how would one kill something that isn't technically alive?... you technically can't... so there's that 0.001%

 

 

 

 

 

 

* This was when I was in middle school like 8 years ago... haven't checked since so don't quote me on that...

I'm not really back. Just not doing so great IRL right now, decided to play some tanks to keep myself busy
