How does XCS-11™ work in oral care products?

Posted July 15, 2022

XCS-11™ is a state-of-the-art oral care ingredient produced by Kemin that offers businesses a new way to give consumers the freshest, best smelling breath possible. Unlike many products that contain ingredients that have potential drawbacks, XCS-11 uses stabilized chlorine dioxide as its active ingredient. Below we’ll explain how XCS-11 works in oral care products and why your business should consider adding this ingredient into its product line.

All the Benefits and None of the Drawbacks

Many of the traditional ingredients in oral care products, including mouthwashes and rinses, have downsides. For example, some products include large amounts of alcohol as an active ingredient. Alcohol can cause a burning or stinging sensation in the mouth. It can also be very drying for sensitive mucus membranes, leaving you with a dry mouth and an environment in which bacteria can multiply. Unfortunately, this is not the only downside of some common oral care ingredients. Other ingredients may lead to tooth discoloration, making your customers’ teeth look darker after using it.

The good news is that stabilized chlorine dioxide does not cause any of these unpleasant stinging or burning sensations. By including XCS-11 in your oral products, your consumers will experience a clean mouth feeling, fresh breath, and no burning sensation or tooth staining. This will set your product apart from others on the market.

Other Benefits Associated with XCS-11

The benefits mentioned above that are associated with stabilized chlorine dioxide are not the only positive effects. In fact, consumers who use XCS-11 regularly may see a wide range of other pluses, such as the ones below.

  • Stabilized chlorine dioxide attacks volatile sulfur compounds that are known for causing bad breath, which means these ingredients tackle the problem directly at its source. A 2015 research study found that using a mouthwash with stabilized chlorine dioxide dramatically boosts oral health while cutting bad breath.
  • XCS-11 breaks up biofilms and reduces the coating that many people may experience on their tongue, cheeks, and roof of their mouth; Biofilm can form tartar, which is very damaging to the teeth and gums.
  • Stabilized chlorine dioxide fights tartar above the gum line and improves overall gum and tooth health. A 2016 study found a significant reduction in plaque and gingivitis once stabilized chlorine dioxide was added to people’s oral health regimen.

These benefits are all attractive to consumers looking for a healthier way to boost their overall oral hygiene.

XCS-11 Is Fast-Acting and Long-Lasting

An additional benefit of XCS-11 is that it is very fast-acting. Many mouth care products take weeks of use before a consumer starts to see a benefit, but this is not the case with XCS-11. Because of its unique formulation, many consumers see improvement within just 15 minutes1! Their breath and their overall mouth health will be enhanced after just one use of the product.

In addition, there is another perk associated with the product for busy people who may not have time to use a mouthwash during their workday. Most people notice that the benefits last for up to 12 hours after use2, leaving one with fresh breath even after a long workday.

Include XSC-11 In Your Oral Care Products

Poor oral health is the cause of many other health problems, mainly because our mouths are a pathway for bacteria to enter the body. By tackling tartar and blocking compounds that cause bad breath, consumers may benefit from not only a healthier mouth environment but also long-lasting fresh breath. Now is the perfect time for manufacturers to consider enhancing or offering new products with odor eliminating ingredients to set themselves apart from their peers and truly help their customers.

At Kemin, we believe that XCS-11 is this standout ingredient. XCS-11 can be used in mouthwash, toothpaste, breath spray, and more. Consumers aren’t just looking for a product that masks bad breath. They’d like to take care of what’s causing unpleasant breath in the first place. Fortunately, XCS-11 is the solution for fresh breath and better overall oral health.
