Summary:

      The purpose of this study is to determine the ability of a marketed denture adhesive to

          -  Is a habitual wearer of both of their dentures defined as participants who wear both

        Exclusion Criteria:

          -  A Participant who is an employee of the investigational site, either directly involved
             in the conduct of the study or a member of their immediate family; or an employee of
             the investigational site otherwise supervised by the investigator; or, a GSK CH

             designee, an acute or chronic medical or psychiatric condition or laboratory
             abnormality that may increase the risk associated with study participation or
             investigational product administration or may interfere with the interpretation of
             study results and, in the judgment of the investigator or medically qualified
             designee, would make the Participant inappropriate for entry into this study.

             and permitted by the examiner. This is to assure that the denture fit will not be
             altered during the study; b) During the treatment visits Participants will not be
             allowed to use tobacco or nicotine or nicotine-containing products following denture
