Bactericidal soap is useless because we wash our hands too quickly

Antiseptic soaps are meaningless because most people use them incorrectly, a new study says.

Antiseptic soaps are becoming increasingly popular but they are little or no effect as many people wash their hands too quickly.

According to him, to kill bacteria, people need to wash their hands with antibacterial soap for about 20-30 seconds , but most of us only do this for an average of 6 seconds. As a result, antibacterial soap will not be more effective than other soaps. Dr. Halden added that, at the same time, bacteria could also adapt to antibacterial ingredients in soap, and resist.

He believes that this even increases resistance to antibiotics - which makes it more difficult for doctors to treat infections. Dr. Halden also warned, there is some evidence that chemicals in antibacterial soap can affect the user's hormone levels.

Over the past 20 years, the number of products containing triclosan and triclocarban - antibacterial chemicals - has skyrocketed. As a result, three-quarters of the US population now has these chemicals in their urine.

The US Food and Drug Administration (FDA) is beginning to control the use of antibacterial products. They said they would have to remove all products unless the manufacturer could prove they were both effective and safe for users.

"FDA's move is an important and necessary step in ensuring the effectiveness of antibiotics, preventing unnecessary contact of people with potentially hazardous chemicals and photos. Endocrine, limiting the increase and accumulation of antimicrobial agents in the environment , " Dr. Halden said.
