Patent number: 9408870Abstract: The present invention relates to an oral care composition and a method of disinfecting the oral cavity. So far synthetic material (e.g. Triclosan) has been used which is believed by many consumers to be harsh on them. Consumers, more and more prefer using products that contain natural materials. Further, in many countries, culturally or otherwise, people are reluctant to using alcohol in their mouthwashes. The present inventors have been working on solving these problems and have come up with an oral care composition which includes natural materials that are found to interact synergistically with certain metal salts in killing S. mutans, a bacterium responsible for tooth decay.Type: GrantFiled: November 17, 2011Date of Patent: August 9, 2016Assignee: Conopco, Inc.Inventors: Maya Treesa Saji, Ritesh Kumar Sinha
