Problem addressed

Some mouthwash products contain chemicals like alcohol and chlorhexidine to help kill bacteria. The use of these chemicals has some potential drawbacks like altered taste sensation and staining of teeth. The new compounds in our invention are non-toxic and natural, so it is safe to be the active ingredients in oral care products.

  • Dihydro-resveratrol or its derivatives have a significant inhibitory effect on the growth of bacteria.
Key impact
  • The compounds are cost-effective and very safe to use as they are herbal extracts, which have fewer harmful effects in comparison with those chemical‐based products.
  • As anti-microbial agents
