Antibacterial soap is pointless because most people do not use it correctly, a researcher has claimed.
• People do not wash their hands for long enough for the soap to work
• They would need to wash their hands for 20 to 30 seconds
• Most only wash hands for an average of six seconds, says Dr Rolf Halden
• Bacteria could also become resistant to the antibacterial chemicals
• This could make it more difficult to treat infections with antibiotics
The increasingly popular product has little or no benefit for most people because they do not wash their hands for long enough.
Dr Rolf Halden, from the Center for Environmental Security, at Arizona State University, says the soaps are beneficial in hospitals where people know how to use them, but that they are pointless in the home.
Dr Rolf Halden says it is pointless for most people to use antibacterial soaps as they do not wash their hands for long enough to allow them to work effectively
He said that to kill bacteria people need to wash their hands with antibacterial soap for 20 to 30 seconds, but that most people only do so for an average of six seconds.
As a result, he says antibacterial soaps will be no more effective than other soaps, Live Science reports.
Dr Halden adds that miicrobes can also adapt to antibacterial ingredients in the soaps, meaning they become resistant to them.
He believes this could even increase their resistance to antibiotics which could make it more difficult for doctors to treat infections.
