Abstract:
A composition for bleaching and removing plaque from tooth surfaces, which is activated by contact with saliva following application to an oral cavity, comprising:1) a homogenous dispersion comprising a) a discontinuous hydrophobic phase containing inert, solid, bleach-stable abrasive polymeric particles having a particle size of between approximately 4 and 150 microns; and b) a continuous hydrophilic phase comprising a peroxide bleaching agent selected from the group consisting of hydrogen peroxide, carbamide peroxide, and mixtures thereof, emulsified in a bleach-stable inclusion complex polymer, wherein said inclusion complex polymer reduces the water-solubility of said bleaching agent, and 2) at least one member selected from the group consisting of a fluoride-yielding compound, a sweetening or other flavoring agent, a preservative, a humectant, and a topical anesthetic.
