Is bar soap antibacterial?

Is bar soap antibacterial

Yes.

From a chemical point of view, soap is alkaline, and bacteria will destroy the bacterial cell wall under alkaline conditions to achieve the effect of decontamination and sterilization; the alkaline property of soap has a strong decontamination ability to the soil, blood stains, and other pollutants.

The reason why soap can sterilize is that soapy water can use its strong alkalinity to destroy the cell wall and osmotic pressure of bacteria, making it difficult for bacterial cells to survive. Therefore, the use of soap in daily life can play a role in sterilization.

In daily life, people choose to use antibacterial soap in order to better sterilize bacteria. In fact, ordinary soap can play a good role in sterilization, and it is not necessary to use antibacterial soap. Under normal circumstances, the germs on the surface of the human body are only attached to the oil on the skin. Ordinary soap can wash off the droplets and other pollutants that wrap the germs on the hands so that the hands can avoid bacterial infection.

Why does soap kill bacteria?

The composition of bacteria is relatively simple. The most basic component is composed of genetic material DNA, RNA, and protein. Lipids form an envelope on the outermost layer of the virus structure, which can not only protect the interior of the virus but also participate in the process of invading cells. The sterilization of ordinary soap is to use the lipid components that destroy the virus shell so that it loses the ability to infect normal cells, so ordinary soap can play a role in sterilization, and the effect is more significant.
