Is Antibacterial Soap Worth the Lather?

The simple act of washing your hands with plain soap can have an important effect on your health. It can help ward off germs—no special soap required. In fact, lathering up with antibacterial soap may not impart better germ protection. Its active ingredient may also do more harm than good.

A lack of solid evidence

The FDA recently questioned the use of antibacterial soap. It proposed a rule requiring manufacturers to prove their products work as claimed. If that's not possible, the companies will have to reformulate their soaps. Or they may need to change the label to continue selling them.

Why the concern? These products claim to fend off more germs than regular soap. But past research shows mixed results on how well they work. In one review of 27 studies, antibacterial soaps did no better than regular soaps. Another study said they might give slightly better protection.

One major drawback: Many of these studies were small in scope. They also didn't specifically test whether the products prevented infections. What's more, the amount of soap used and hand scrubbing time varied.

Safety considerations

The FDA is also concerned about the safety of certain chemicals in antibacterial soaps. Many of these products contain triclosan. It's an ingredient that may stop the growth of bacteria. You can find it in many other consumer products, such as toys, carpeting, and cosmetics.

Some animal studies suggest triclosan may alter hormone production. But no such link has yet been found in humans. Plus, scientists don't know the chemical's long-term effects.

Triclosan may also contribute to the growing threat of antibacterial resistance. More bacteria are becoming immune to antibiotics. This resistance is making it harder to treat many illnesses.

To date, the FDA has not found enough evidence to ban the use of triclosan. But it's currently working with the EPA to better understand how the chemical may harm human health. For now, you can easily protect yourself from germs by washing your hands with regular soap and water.

 

Hand Washing Tips 

Washing your hands is a healthy habit worth doing right. It can help protect you against illnesses like the common cold and the flu. Remember to wash your hands often and follow these tips:

  • Use warm water and plenty of soap. Work up a good lather.

  • Clean the whole hand, under your nails, between your fingers, and up the wrists.

  • Wash for at least 15 to 20 seconds. Don’t just wipe. Scrub well.

  • Rinse, letting the water run down your fingers, not up your wrists.

  • Dry your hands well. Use a paper towel to turn off the faucet and open the door.
