Poll: Why does hand soap always say that they kill 99.9% of bacteria but never 100%?

I've always wondered about that. :/Poll: Why does hand soap always say that they kill 99.9% of bacteria but never 100%?
aha but i have a solution put some extra soap to add more chance of removing that 1%Poll: Why does hand soap always say that they kill 99.9% of bacteria but never 100%?
If they said 100% and someone still got sick, they would get sued. Stheyey say 99.9 percentso there's's that 0.01 percent of getting sick. Report Abuse

Because declaring that the soap kills 100% of all bacteria would be a false statement which could lead to lawsuits. Some bacteria cannot be killed by the mild chemicals that are in hand soap. Hence why bacteria can outlive a nuclear blast.
cus if you used it and then stuck your hand under a microscope, you would find bacteria and so they say 99% as a disclaimer so its not false advertising....





I agree, its dumb
because nothing is perfect.


it'll never be 100%.


please, not all anti-bacterial soaps are entirely anti-bacterial.


how about putting dusts inside the bottle of hand soap?
because they cant guarantee 100% of the bacteria will be killed
very few things can kill 100% of all bacteria. Thats why people are dying with MRSA.
downplaying expectation
thats just the way it works


if you want that 1% killed add bleach to your soap
Because it doesn't kill all of it.
because they can't be sure it'll kill every single germ.
idk, because that one percent will not be killed....who knows?
