Does Bar Soap Really Kill Germs?

New to bar soap? Read our Bar Soap Guide for quick answers about lye, germs and choosing the right bar.

Quick answer

Yes. Bar soap removes germs as well as liquid soap: soap lifts dirt, oil, bacteria and viruses off your skin so water can rinse them away. Studies have found that germs on a used bar rarely pass to the next person. Lather for 20 seconds, rinse well, and let the bar dry between uses.

A Comprehensive Comparison of Bar Soap and Liquid Soap

Have you ever paused to consider the soap that sits in your shower or on your sink? When bar soap sits exposed in the bathroom, it can appear seemingly vulnerable to germs and contaminants, raising questions about its sanitation. Is it genuinely effective at keeping germs at bay? The truth is, the surfactants in bar soap combine with water to lift bacteria and viruses off the skin and wash them down the drain. At Ollie Skincare, we are enthusiastic about providing natural and effective skincare solutions.

Today, we’re diving deep into the long-standing debate of bar soap versus liquid soap, aiming to uncover the truth about how well each one removes germs and highlight best practices for hygienic handwashing. This topic brings up some interesting questions about the cleanliness and safety of using bar soap.

The Great Soap Showdown: Bar vs. Liquid

When it comes to selecting between the bar and liquid soap, the decision involves more than just personal taste; it encompasses various factors, including effectiveness, convenience, and even environmental implications. Unlike liquid soap, which is dispensed from a container and remains protected from the environment, bar soap is exposed to air and surfaces, so it may require more attention to hygiene. Generally speaking, keeping bar soap on a soap dish that allows it to dry between uses is important to reduce bacterial growth and maintain the soap's longevity. Using a drainable soap dish helps keep the bar soap dry, which can prolong its life and reduce bacteria. Here’s an in-depth look at both:

Bar Soap: The Classic Cleanser

  1. Germ-Removing Power: Many individuals harbor the misconception that bar soaps are less effective at eliminating germs compared to their liquid counterparts. However, a bar of soap can be incredibly effective. The key component is the mechanical action involved in rubbing the soap bar against your skin, which washes away dirt, oil, and germs, as well as other microorganisms, effectively cleansing the skin. While a bar of soap may harbor more bacteria than liquid soap, proper rinsing and drying after use can significantly reduce bacterial levels. It's also important to note that all the germs on the soap's surface are unlikely to transfer to your skin during use. As you use the same bar repeatedly, skin cells and other microorganisms from your own body can transfer to the soap, but this is generally harmless. Using the same bar does not necessarily increase the risk of illness. Some people worry that they are essentially rubbing germs onto their skin with each use, but studies show this is not a significant concern. Over time, a bar of soap may collect a weird little sliver as it gets used up, but this does not impact its effectiveness or hygiene. Overall, a soap bar remains a practical and hygienic choice for daily cleaning.

  2. Natural Ingredients: We take pride at Ollie Skincare in our range of bar soaps crafted with nourishing goat milk and other beneficial natural components. These formulations not only provide thorough cleansing but also leave skin feeling soft and moisturized, making it a win-win option for those seeking effective skincare. Bar soap is commonly used to wash the body as well as hands, supporting overall hygiene.

  3. Environmental Impact: In today’s eco-conscious world, the environmental ramifications of our choices matter. Bar soaps generally come with much less packaging, often eliminating the need for plastic containers. This leads to a reduced carbon footprint and less waste ending up in landfills, contributing to a more sustainable lifestyle.

Liquid Soap: The Modern Contender

  1. Convenience: Liquid soaps often overshadow bar soaps in the convenience department, particularly in public settings like restrooms or kitchens. Liquid hand soap is a popular choice for public and home use due to its easy pump or squeeze bottle dispensing mechanism, which can be more straightforward and less messy, making for a user-friendly experience. There are so many soaps available, each with different features and ingredients, making it important to choose the right one for your needs.

  2. Moisturizing Properties: Many formulations of liquid soap integrate additional moisturizers, catering particularly to individuals with dry or sensitive skin. Body washes are another form of liquid soap designed for use on the entire body, often formulated with moisturizing ingredients. These added elements can help counteract the drying effects that some cleansing agents might have, leaving your skin feeling softer after washing.

  3. Hygienic Concerns: A common worry surrounding bar soap involves the potential for bacteria to accumulate on its surface. However, research indicates that while bacteria can indeed exist on bar soap, the likelihood of these microorganisms transferring to your skin during regular use is minimal. Antibacterial chemicals are sometimes added to consumer products, including some liquid soaps, to help reduce bacterial contamination.

The Science of How Soap Removes Germs

Both bar and liquid soaps rely on similar scientific principles when it comes to effective germ removal. Key elements to consider include:

  • Surfactants: These vital compounds work by lowering the surface tension of water, which allows the soap to effectively spread across and lift away dirt and oils from the skin’s surface for a thorough cleanse.

  • Antibacterial Effectiveness: While some soaps are marketed as “antibacterial,” it is crucial to understand that regular soap and water do not directly kill bacteria but instead remove them from the skin. Some antibacterial products claim to offer extra protection by killing germs, but the FDA says there isn't evidence that they work better than plain soap and water for preventing illness. Certain active ingredients, such as triclosan, have been scrutinized for safety and efficacy, and the U.S. Food and Drug Administration issued a final rule banning certain antibacterial ingredients from over-the-counter soaps due to a lack of proven effectiveness and potential health risks, including hormonal effects from long term exposure. Long-term use of antibacterial soap can lead to antibiotic-resistant bacteria and hormonal effects, raising safety concerns. Antibacterial soaps may give a false sense of security, but plain soaps are effective for hand hygiene and do not require antibacterial ingredients. It makes sense that regular soap is sufficient for most uses, and antibacterial products are not necessary for most people outside of healthcare settings. While some believe antibacterial soaps are safer for their families, plain soap is recommended for general use. Hand sanitizers are also alternatives to soap and water, and are regulated separately by the FDA. According to the CDC, washing hands with soap and water is one of the most important ways to help prevent the spread of germs.

  • pH Levels: True soaps are naturally alkaline, while many liquid soaps are formulated closer to skin’s natural pH. Either way, it’s the lather, scrubbing, and rinsing that remove germs.

Mastering the Art of Hygienic Handwashing

Choosing the right soap is only part of the equation; the technique used during hand washing is crucial for removing germs. Washing your hands with soap and clean water is one of the most important steps you can take to help prevent the spread of germs. Frequent hand washing, especially after touching contaminated surfaces, is essential for maintaining good hygiene.

Here’s a comprehensive guide to effective hand washing:

  1. Wet your hands with clean, running water (warm or cold). Using clean water is important to ensure proper removal of germs.

  2. Apply soap and create a rich lather, ensuring coverage of all hand surfaces, including between fingers and beneath nails. To properly wash your hands with bar soap, wet the soap and create a lather for at least 15 seconds before washing your hands.

  3. Scrub all surfaces for at least 20 seconds—approximately the time it takes to hum “Happy Birthday” twice. Be sure to wash your hands whenever there is visible dirt, as hand sanitizers are not effective when hands are visibly dirty.

  4. Rinse thoroughly under clean, running water. Make sure all soap and loosened germs are rinsed away.

  5. Dry your hands using a clean towel or air dry them.

Proper hand washing removes dirt and microbes from your hands. Dry your hands using a clean towel after washing them with bar soap to maintain hygiene.

Remember: The effectiveness of handwashing hinges not just on the soap but rather on the scrubbing action and the duration you dedicate to the process. For more information, explore the CDC handwashing recommendations

Wrapping Up: The Verdict on Bar Soap vs. Liquid Soap

So, does bar soap truly kill germs? Not exactly—soap works by lifting germs off your skin so they rinse away, rather than killing them. Both bar and liquid soaps are effective at cleansing and removing germs when used appropriately. Ultimately, the decision between the two boils down to personal preferences, specific skin needs, and environmental considerations.

Keep in mind that the essentials of efficient handwashing lie not in the type of soap selected but rather in your washing technique and the time invested in scrubbing.
