Difference Between Antibacterial and Disinfectant

Some common cleaning products may be confusing. Soaps and cleaners are often labeled "antibacterial" or "disinfectant." Understanding the difference may help you choose the product you need.

Antibacterial

• "Antibacterial" means the product kills or interferes with the growth of bacteria. "Antibacterial" applies to chemicals used to treat surfaces, not medicines. According to Tufts University, antibacterials generally are either short-acting with no residual chemicals, such as alcohol or chlorine, or are long-acting, such as triclosan.

Disinfectant

• Disinfectants kill bacteria,viruses and fungi.

  The Environmental Protection Agency (EPA) regulates how cleaners are classified. A disinfectant must destroy all microorganisms the label lists on the product. Disinfectants kill not only bacteria but also viruses and fungi.

Significance

• According to Tufts University, a study found that in 10 states, 76 percent of liquid soaps and 30 percent of bar soaps contained an antibacterial agent. Many kitchen, bathroom and household cleaners contain antibacterial or disinfecting chemicals.

Selection

• Short-acting agents, either antibacterial or disinfectant, that do not leave a residue are safest for home use. According to Tufts University, use of long-acting cleaners may be effective and necessary for use in health care facilities where risks of infection are significant.

Considerations

• Plain soap used correctly kills germs.

  According to the Mayo Clinic, hand washing with regular soap is effective and there is evidence that antibacterial cleaners can create some antibiotic-resistant bacteria.
