The most common hand soaps and bath soaps contain chemical ingredients such as alcohol or chlorine that kill bacteria. Soap labeled "antibacterial" contains extra bactericidal substances such as triclosan or triclocarban. Several laboratory studies at the University of Michigan School of Public Health have shown that after the use of triclosan-containing soaps, bacteria exhibit some resistance to antibiotics. Frequent use of soaps containing extra bactericidal ingredients is less effective at preventing infectious diseases and reducing disease levels of bacteria than people using regular soap.
The authors of the study called for further evaluation by the US Food and Drug Administration (FDA) to replace generic soaps in soaps that claim to be antibacterial products in advertising, specifically considering the use of triclosan-containing soaps that lack long-term health benefits.
According to the Centers for Disease Control and Prevention (CDC), the problem of dirty hand-transmitted diseases is not due to the lack of use of soap containing extra bactericidal components, but because the public does not wash their hands adequately. Most people spend less than 5 seconds on their hands and do not have enough time to kill bacteria. The best way to get rid of harmful bacteria is to wash your hands with warm water and keep it for a long time.
"Washing hands very carefully - pushing hard on the back, hands and fingers is the most effective way to get rid of bacteria and dirt on your hands," said Wenger Peter, an associate professor of preventive medicine at the University of Dentistry of New Jersey and a specialist in community pediatric health. Some bacteria are needed to help digestion and resist harmful bacteria. Not all bacteria in your hands are harmful, your body needs the balance of bacteria, and maintains a healthy environment that is good for the skin.â€
