In most disinfectants, or in the articles above the boxes, 99.9 %of the germs are arguing. Probably never heard of what they say 100 %.

Can’t science develop a 100 %effective disinfecting against germs? The reward of this problem; We can explain it with microbiology and mathematics.

Let’s start from the foundation: What is disinfectant?

Disinfectant; It is an element used to kill or neutralize bacteria, viruses and other germs in inanimate objects.

There are millions of germs on surfaces and objects in our home environment. Although there are not more than one germ Ziyanlı (even some good for us), a small part of it can be bizihasta.

Chemical disinfectants often contain alcohols, chlorine compounds and hydrogen peroxide that can kill them by taking the vital components of different microbes.

Let’s explain the mathematics of microbial elimination.

As the number of germs decreases with time in the process of killing or ineffective microbes, the ratio of microbes slows down.

For example, if the disinfectant kills 90 %of bacteria every minute, only 10 %of the original bacteria remain. After the next minute, this kind of 10 %of the remaining 10 %continues.

It is not possible to argue that you can kill 100 %of a random microbial population due to the phenomenon called “logarithmic degradation pattern”. That is why the disinfectants sold for residential use kill many of the handkerchiefs and 99.9 %of germs.

There are a number of factors to consider when evaluating how much a disinfectant will clean the germs from a surface.

The size of the first microbial population you are trying to get rid of is valuable. In other words, the more dirty a surface is, the harder the disinfectant needs to work to destroy germs.

For example, if there are 100 germs on a surface or object and destroy 99.9 %of them using a disinfectant, you can effectively destroy all germs from that surface or object.

On the other hand, if there is a large microbial population of hundreds of millions or billions of germs that pollute a surface, even reducing the microbial load by 99.9 %may mean potentially millions of germs on the surface.

Time is a valuable factor that determines how influential microbes will be killed. Exposure of a very dirty surface to disinfectant will allow you to kill more microbial populations.

Already in the instructions for use of many disinfectants, after applying the work should wait for a while before cleaning. Therefore, don’t forget to read the label you use!

In addition, measures are taken against customer complaints.

If the work had promised 100 %pure, and if a user had complained that he had not killed all of the germs, antibacterial producers would have faced legal problems. In other words, they leave a kind of open door by saying 99.9 %.
