Antibacterial vs. regular soap

Antibacterial soap is not any more beneficial at destroying COVID-19 than regular hand soap. Why and what's the difference between the two in the first place?

Antibacterial soap "contains extra chemicals designed to kill or inhibit the replication of bacteria," explains Kasey Nichols, NMD, the medical contributor for RAVEReviews.org. That sounds good, but it turns out that all those chemicals don't actually provide any extra power when it comes to fighting viruses. "Antibacterial soaps target bacteria, and coronavirus is a virus. So an antibacterial soap is unnecessary," says Morton Tavel, MD, clinical professor emeritus of medicine at Indiana University School of Medicine.

Even when not just dealing with the coronavirus, antibacterial soap isn't any more beneficial than regular soap. The Food and Drug Administration (FDA) has yet to find any evidence that antibacterial soaps are more effective than any other type of soap. Regular soap gets the job done—even when that "job" is killing the novel coronavirus.

How does soap kill the virus?

You might still be skeptical. After all, this virus is so nefarious that it's easy to doubt that just plain soap could negate it. Well, fortunately, it can!

Technically, "soap is not designed to kill germs on contact, but rather to wash germs away," explains Dr. Tavel. Essentially, soap does what water can't—it breaks down the fatty membrane that viruses have around them, causing the whole virus to break down. That membrane repels plain water similarly to the way oil does. Introduce soap and its ingredients, called surfactants, which attracts the contents of the membrane, causing it to break down. "The surfactants in soap lift up and break apart dirt and microbes from your skin, and the friction of rubbing your hands together helps remove the particles so they get washed down the drain," Dr. Tavel explains.

This process takes time, which is why it's so important to wash your hands for at least 20 seconds. Pair regular soap with the thorough washing of your hands, and viruses are removed from your hands and washed away—no fancy chemicals needed.

Is antibacterial soap dangerous?

Well, the jury's still out on that subject. But the FDA has definitely found a couple of valid causes for concern when it comes to using antibacterial soap. One of the most common antibacterial agents is triclosan, which has been shown in some animal trials to alter hormone function. Its effects have undergone investigation from both the FDA and the Environmental Protection Agency (EPA).

That's not all. "There has also been concern surrounding whether or not antibacterial soap chemicals are causing bacteria to become more resistant to these chemicals and other antibacterial drugs," Dr. Nichols explains. Basically, the very bacteria that these soaps are supposed to kill might instead be evolving to become stronger and fight them.

Unless you're someone who already buys antibacterial soap, you don't have to worry about these concerns—because antibacterial soap isn't more helpful against the virus anyway! So stick to regular liquid and bar soaps. And, of course, make sure you're taking the most important step to prevent the virus: properly washing your hands. Wash for 20 seconds, making sure to scrub everywhere, including the backs of your hands and between your fingers.

FRAGRANCE

"If you only change one thing in your beauty routine, the ingredient you should avoid is fragrance," says Lindsay Coulter, the David Suzuki Foundation's resident green living expert. Labelled as "parfum" on Canadian beauty product labels, fragrance isn't just in colognes or perfumes; in fact, it's added to everything from body wash to shampoo to face creams. Even unscented products can contain fragrance compounds that act as masking agents. "It shows up as one word [on the ingredients label], but it can be a concoction of hundreds of different ingredients," Coulter explains. According to research published by the Canadian Cosmetic, Toiletry and Fragrance Association, these anonymous chemical compounds can trigger allergies and asthma, cause hormone disruption, and in many cases, are harmful to fish and other wildlife after they get washed down the drain.

Not ready to give up smelling pretty? There are still plenty of green alternatives, says Jen Newell, a Toronto-based naturopath. "I recommend that people opt for products with essential oils or other natural scents," Newell says.

PARABENS

Parabens are preservatives that can be found in everything from makeup to moisturizers to fragrances. Problem is, numerous studies have shown that these chemicals—which are easily absorbed through the skin—have the potential to interfere with hormone function and have been linked with breast cancer. How do you rid your beauty routine of this particularly harmful ingredient? Keep an eye out for products that are labelled "paraben-free," and study the ingredient list carefully, as these pesky preservatives can be listed in different ways, including "methylparaben" or "propylparaben

TRICLOSAN

Triclosan is an antibacterial agent that can be found in antibacterial soaps, body washes, hand sanitizers, toothpaste and mouthwash. The issue with triclosan, Coulter says, is that it kills all bacteria—good and bad. Although this ingredient is not yet regulated in Canada, the Food and Drug Administration in the United States banned its use in September 2016 on the grounds that it could pose health risks, including bacterial resistance and hormonal effects. The good news? It's easy to steer clear of this harmful ingredient, as triclosan is listed on product labels

SODIUM LAURYL SULPHATE

Sodium lauryl sulphate (SLS, sometimes also known as SLES) is a chemical additive that makes super-foamy bubbles and suds. It's often listed as a main ingredient in soap, shampoo, face wash and dish soaps, says Coulter. The reason that SLS should be avoided is that it can be contaminated with ethylene oxide, which the International Agency for Research on Cancer lists as a known human carcinogen (cancer-causing chemical). Check your soaps for this ingredient before purchasing and don't fret if the SLS-free product you try doesn't produce a rich lather like your old shampoo or body wash. A lack of suds doesn't mean it's not doing it's job, says Coulter; it simply means you're skipping out on a harmful chemical.

PHTHALATES

Phthalates are commonly found in fragrance compounds and may be labelled simply as "parfum" on product packaging, says Newell. Research suggests they can disrupt hormones during critical periods of human development (such as a baby's development in utero) and they've also been associated with male infertility.

If you're having trouble identifying which products might contain harmful ingredients such as phthalates, Newell recommends downloading the Think Dirty App to your smartphone. It allows you to scan the bar codes of the products in your daily beauty regimen, and then assesses their degree of safety.

OXYBENZONE

Oxybenzone is the active ingredient in many popular sunscreens, but Newell recommends avoiding it when possible—and for good reason. According to a study published in the International Journal of Andrology, oxybenzone has been linked to skin reactions and it may even disrupt hormones. There have also been studies indicating that when oxybenzone is exposed to sunlight it can form free radicals that cause skin cell damage. This doesn't mean you should skip sunscreen altogether, of course. It's easy to avoid this chemical if you stick with mineral-based zinc or titanium oxide sunscreens.

PETROLATUM

Petrolatum or petroleum jelly is often used in moisturizers, lip balms and hair products because it acts as a moisture barrier and creates a sheen. The David Suzuki Foundation lists petrolatum as one of its "Dirty Dozen" harmful ingredients to avoid, as it can be contaminated with polycyclic aromatic hydrocarbons (PAHs), which the European Union lists as a carcinogen. Nevertheless, the use of PAHs are not currently restricted by Health Canada.

If you want to skip petrolatum just to be on the safe side, try organic coconut oil or shea butter to moisturize your skin.

If you're feeling overwhelmed when it comes to "greening" your beauty routine, begin the transition slowly. "Start with the products you use most often and then eventually replace those items that you only use every once in a while," recommends Newell.
