Optimizing the mildness and taste of mouthwashes

Oral Care Concept

Consumers have become increasingly conscious about the benefits and importance of oral hygiene over the past few years. For many, the use of mouthwash is already part of their daily oral care routine. With the launch of a new and highly innovative ingredient, Evonik Personal Care offers formulators a magnificent opportunity for natural oral care. 

  • Mild mouthwashes are in high demand from consumers

  • Benefits: Already part of consumers daily oral care routines

  • The challenge: Ingredients can often irritate the consumer’s mucous membranes leaving a bitter taste

  • Evonik’s solution: A highly cleansing, but mild and natural cosmetic ingredient

  • Product highlight: RHEANCE® One

Research within the oral care market has shown that consumers are increasingly looking for effective but mild mouthwashes. Claims such as ‘alcohol-free’, ‘mild’ or ‘natural’ are gaining more and more popularity among consumers. Mouthwash ingredients now need to not only solubilize flavors, provide a comfortable taste and have almost no foaming properties, but they are also required to be mild and ideally made from natural ingredients and be eco-friendly. Though, most common mouthwashes still include standard PEG-free solubilizers such as Cocamidopropyl Betaine and Sodium Lauryl Sulfate, both as tested in our labs are proven to leave a long lasting bitter taste in the mouth, or worse can cause irritation to consumers’ mucous membranes, which is true especially for Sodium Lauryl Sulfate.
With the launch of RHEANCE® One, Evonik has achieved a tremendous breakthrough in natural cosmetic ingredients technology. Based on nature-identical biomolecules made only from the fermentation of sugars and therefore 100% based on renewable feedstocks, the high-performance Glycolipid stands for a new era for the cosmetic ingredients industry. It provides high cleansing, while at the same time a remarkable mildness to both the skin and mucous membranes. To ensure its suitability for mouthwashes, RHEANCE® One was extensively tested for its mildness and compatibility to mucous membranes, the solubilizing of different oral care flavors and its foaming properties, as well as its taste. By outperforming most tested chemically produced cosmetic ingredients, RHEANCE® One has once again proven to be the perfect solution for efficient but mild mouthwashes. 

With this concept and the introduction of RHEANCE® One, Evonik offers an innovative approach to the oral care routines of environmentally conscious consumers, and provides a solution that is not only gentle to our oral mucosa, but also gentle to our planet.

ANTIL® 500 Pellets

As an innovative hydrophilic polymer, ANTIL® 500 Pellets enables a significant reduction of the active surfactant level in standard cleansing formulations. In addition, the extraordinary efficiency and high flexibility of ANTIL® 500 Pellets facilitate the thickening of challenging surfactant systems, such as sulfate-free formulas, effectively supporting the trend for milder cleansing in personal care. The 100% active, preservative-free solid is clearly soluble in water and processable at room temperature. Furthermore, ANTIL® 500 Pellets is stable against hydrolysis and effective over a wide pH range. The thickening agent provides a rich formulation texture with Newtonian flow behavior but without changing the foaming characteristics, which is essential for fulfilling the consumers’ sensorial expectations of personal cleansing products.
