  • Oral cavity cleaning composition method and apparatus
    Patent number: 11918677
    Abstract: A composition for improved oral care includes fibrillated material and friction elements for removal of plaque biofilm, and additional ingredients useful in oral care compositions. The composition also may include particulate SuperAbsorbent Polymer, which may be surface cross-linked. Certain ingredients may be minimized or avoided to reduce the lubricity of the composition. The composition may be a viscoelastic fluid having a desired viscosity, yield stress and elastic modulus. The efficacy can be characterized by its removal of biofilm due to flow inside tubes. Also useful are standard rheological and tribological measurements. Also disclosed are apparatus for administering the composition, and methods.

  • Oral cavity cleaning composition, method, and apparatus
    Publication number: 20210330557
    Abstract: An oral hygiene composition includes a mixture of: (i) a carrier liquid; and (ii) a water-insoluble hydratable polymer fibers forming an entangled three-dimensional network of said water-insoluble hydratable polymer fibers in said carrier; wherein: said carrier liquid comprises one or more humectant in a concentration of total humectant in excess of 5 wt. % based on the weight of the composition; said composition has an elastic modulus G? and a loss modulus G?, and said elastic modulus G? is larger that said loss modulus G?; and said water-insoluble hydratable polymer fibers have a diameter of about 10 to about 20,000 nm and a length of at least 100 nm.
