Dial antibacterial soap is a decent everyday cleanser, but it probably doesn’t give you a meaningful advantage over regular soap. The FDA has stated plainly that there is no data demonstrating antibacterial soaps provide additional protection from diseases and infections beyond what plain soap and water already offer. That said, Dial remains one of the few antibacterial soaps still legally sold in the U.S., and some people swear by it for specific uses like body acne or tattoo aftercare.
What’s Actually in Dial Antibacterial Soap
Dial’s active ingredient is benzalkonium chloride at 0.10%, a type of quaternary ammonium compound used widely in disinfectants and antiseptics. This matters because in 2016, the FDA banned 19 common antibacterial soap ingredients (most notably triclosan) after finding they weren’t proven safe or effective for consumer use. Benzalkonium chloride was one of only three ingredients the FDA allowed to remain on the market while manufacturers conducted additional safety and effectiveness studies. So Dial reformulated and survived the ban, but that doesn’t mean its antibacterial claims have been validated. It means the ingredient is still under review.
How It Compares to Plain Soap
The core question most people have is whether Dial’s antibacterial formula kills more germs than regular soap. The honest answer: no strong evidence says it does. The FDA’s consumer guidance is titled “Skip the Antibacterial Soap; Use Plain Soap and Water,” which tells you where the agency lands on this.
Plain soap works by lifting bacteria and viruses off your skin so water can rinse them away. It doesn’t need to kill anything to be effective. Antibacterial soaps aim to kill microbes on contact, but during a normal 20-second handwash, there isn’t enough contact time for benzalkonium chloride to provide a measurable extra benefit. Even in pre-surgical settings, a Cochrane review of over 10,000 patients found no clear evidence that antiseptic washes reduced surgical site infections compared to regular soap. When three trials directly compared bar soap to an antiseptic wash, the infection rates were essentially identical.
The Antibiotic Resistance Concern
One reason the FDA has pushed back on antibacterial soaps is the potential link to antibiotic resistance. Research published in Nature Communications found that bacteria exposed to benzalkonium chloride can develop tolerance to it over time, and that tolerance can spill over into reduced susceptibility to actual antibiotics. In lab settings, bacteria adapted to benzalkonium chloride showed elevated resistance to certain antibiotics, and those resistant bacteria even gained a survival advantage in environments containing low levels of antibiotics.
This doesn’t mean washing your hands with Dial will create a superbug in your bathroom. But it does suggest that widespread, routine use of antibacterial products across millions of households could contribute to resistance patterns at a population level. For everyday handwashing, the risk-benefit math doesn’t favor antibacterial soap when plain soap works just as well.
Where Dial Gets Recommended: Tattoos and Acne
Despite the lukewarm evidence for general handwashing, Dial has carved out a loyal following in two specific niches.
Tattoo artists frequently recommend Dial Gold antibacterial liquid soap for aftercare. The reasoning is practical: a fresh tattoo is essentially an open wound, and artists want clients using something that won’t introduce fragrance-heavy or harsh chemicals while still being antibacterial. The standard instruction is to wash the tattoo gently with Dial Gold to remove plasma and blood, then follow with a thin layer of unscented lotion. Artists typically specify liquid soap over bar soap to avoid pressing a shared surface against broken skin.
For body acne and occasional facial acne, Dial has a strong anecdotal reputation. Some dermatologists recommend it, particularly for bacterial acne or folliculitis on the back, chest, and shoulders. People report significant clearing within a week or two of daily use. The antibacterial action may help in this context because the soap sits on acne-prone skin longer than it does during a quick handwash, and bacterial overgrowth plays a direct role in many types of breakouts.
The major trade-off is dryness. Dial antibacterial soap strips moisture aggressively. People who use it for acne consistently warn that heavy moisturizing afterward is non-negotiable. For some, especially those with a damaged skin barrier, the drying effect actually worsens breakouts. If your acne is driven by irritation or dryness rather than bacteria, Dial will likely make things worse.
Is It Safe on Your Skin?
At the concentration used in Dial (0.10% benzalkonium chloride), safety data is generally reassuring for intact skin. A risk assessment found that benzalkonium chloride is not genotoxic and shows no tumor-promoting potential, with adequate safety margins for products applied to the body. The main concerns researchers have flagged involve sensitive areas like eyes and nasal passages, not typical hand or body washing.
That said, the same assessment noted that comprehensive long-term skin absorption studies are still lacking. For occasional or targeted use, there’s no red flag. For people who wash their hands a dozen times a day, the drying and irritating effects of the soap itself are a more immediate concern than the active ingredient.
The Bottom Line on Daily Use
For routine handwashing, Dial antibacterial soap doesn’t offer a proven advantage over any plain soap. It cleans your hands, it smells familiar, and it won’t harm you, but the “antibacterial” label isn’t doing what most people assume it does. If you like how Dial feels and you’re not paying a premium for the antibacterial version, it’s fine to use. Just don’t choose it over regular soap thinking it provides extra germ protection.
Where Dial may earn its keep is in targeted situations: managing body acne, caring for a fresh tattoo, or dealing with a skin condition where your doctor has specifically recommended an antibacterial wash. In those cases, the antibacterial properties have more time and reason to work, and the trade-off of extra dryness can be managed with moisturizer.
