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.
