Is It Bad to Use Disinfecting Wipes on Your Hands? Find Out

In today's world, disinfecting wipes have become a common household item, particularly in the wake of the COVID-19 pandemic. These wipes are handy, convenient, and seemingly effective at killing germs. But what happens when you're out and about, with no hand sanitizer in sight, and you consider using a disinfecting wipe on your hands? Is it safe? Is it effective? Or could it be doing more harm than good? This article delves into the realities of using disinfecting wipes on your hands, assessing the potential risks and benefits, and providing practical advice based on the latest research and expert opinions.

Understanding Disinfecting Wipes: What Are They Made Of?

Disinfecting wipes are pre-moistened towelettes that contain a cleaning solution designed to kill bacteria and viruses on surfaces. The active ingredients often include quaternary ammonium compounds (quats), alcohols, hydrogen peroxide, and sometimes bleach. These ingredients are effective at killing pathogens, but they are also potent chemicals that are not necessarily safe for all uses, particularly when it comes to skin contact.

Quats, for example, are a common ingredient in disinfecting wipes. They are known for their broad-spectrum antimicrobial activity and are effective against bacteria, viruses, and fungi. However, quats can be irritating to the skin, causing dryness, redness, and in some cases, allergic reactions. Alcohol-based wipes are generally considered safer for skin contact, as alcohol evaporates quickly and is less likely to cause irritation. However, frequent use can still lead to dryness and cracking of the skin.

Can Disinfecting Wipes Replace Hand Sanitizer?

Hand sanitizers are specifically formulated for use on the skin. They typically contain between 60% and 95% alcohol, which is effective at killing most bacteria and viruses. Unlike disinfecting wipes, hand sanitizers are designed to be safe for frequent use on hands, including sensitive skin.

When you don't have access to hand sanitizer, it might seem logical to reach for a disinfecting wipe. However, it's important to understand that disinfecting wipes are not designed for use on the skin. While they may kill some germs on your hands, they can also strip away natural oils and damage the skin barrier, leading to dryness, irritation, and potentially increasing your risk of infection.

In situations where soap and water or hand sanitizer are unavailable, using a disinfecting wipe might be better than nothing, but it should be a last resort. If you do use a wipe on your hands, it's crucial to follow up with a thorough wash with soap and water as soon as possible.

The Risks of Using Disinfecting Wipes on Your Skin

1. Skin Irritation and Allergies: Disinfecting wipes contain chemicals that can cause skin irritation, especially with repeated use. Quats, in particular, are known to cause contact dermatitis, a type of skin inflammation that can result in redness, itching, and even blistering. If you have sensitive skin or a history of allergies, you are at a higher risk of developing a reaction to these wipes.
2. Chemical Absorption: The skin is not entirely impervious; it can absorb certain chemicals into the bloodstream. While the occasional use of a disinfecting wipe on the hands is unlikely to cause significant harm, frequent use could lead to the absorption of harmful chemicals. Some studies have raised concerns about the potential long-term effects of quat exposure, including respiratory issues and endocrine disruption.
3. Damage to the Skin Barrier: The skin's outer layer, known as the stratum corneum, acts as a barrier to protect against pathogens and environmental damage. Disinfecting wipes can strip away the natural oils that maintain this barrier, leading to dryness, cracking, and increased vulnerability to infections. This is particularly concerning during cold weather, when the skin is already prone to dryness.
4. Ineffectiveness Against Certain Germs: Not all disinfecting wipes are equally effective against all types of pathogens. Some wipes are formulated to kill specific bacteria and viruses but may not be effective against others, such as certain types of fungi or spores. This means that even after using a disinfecting wipe on your hands, you may still be at risk of spreading or contracting infections.

What the Experts Say

Healthcare professionals generally advise against using disinfecting wipes on your hands, particularly as a substitute for handwashing or hand sanitizer. According to the Centers for Disease Control and Prevention (CDC), handwashing with soap and water is the best way to remove all types of germs, while alcohol-based hand sanitizers are a good alternative when soap and water are not available. The CDC does not recommend the use of disinfecting wipes on skin.

Dermatologists also caution against the frequent use of disinfecting wipes on the hands. The harsh chemicals in these wipes can disrupt the skin's natural balance, leading to a host of issues, from minor irritation to more severe allergic reactions. For those with pre-existing skin conditions, such as eczema or psoriasis, the use of disinfecting wipes can exacerbate symptoms.

Safer Alternatives When Hand Sanitizer Is Unavailable

If you find yourself without hand sanitizer, there are safer alternatives to using disinfecting wipes on your hands:

1. Soap and Water: Whenever possible, wash your hands with soap and water for at least 20 seconds. This is the most effective method for removing dirt, bacteria, and viruses from your hands.
2. Alcohol Wipes: If you have access to alcohol wipes (containing at least 60% alcohol), these are a safer option for hand hygiene than disinfecting wipes. Alcohol wipes are designed for use on the skin and are effective at killing most germs.
3. Homemade Hand Sanitizer: In a pinch, you can make your own hand sanitizer using isopropyl alcohol (at least 60%) and aloe vera gel. Mix two parts alcohol with one part aloe vera, and store it in a clean, sealed container for use when needed.
4. Moisturizing Hand Cream: After washing or sanitizing your hands, apply a moisturizing hand cream to help restore the skin's natural barrier and prevent dryness and irritation.

Conclusion: Weighing the Risks and Benefits

Using disinfecting wipes on your hands should be a last resort when no other options are available. While these wipes can kill germs, the potential risks to your skin and overall health make them less than ideal for regular use. The harsh chemicals in disinfecting wipes can cause skin irritation, damage the skin barrier, and lead to the absorption of potentially harmful substances. In contrast, hand sanitizers and soap and water are both effective and safe for frequent use on the skin.

If you must use a disinfecting wipe on your hands, do so sparingly, and wash your hands with soap and water as soon as possible afterward. Additionally, be mindful of any signs of skin irritation or allergic reactions, and discontinue use if you experience any adverse effects.

In summary, while disinfecting wipes are a valuable tool for keeping surfaces clean and reducing the spread of germs, they are not a substitute for proper hand hygiene. Stick to soap, water, and hand sanitizer whenever possible, and reserve disinfecting wipes for their intended purpose: cleaning and disinfecting surfaces.
