1. A non-aqueous oral care composition comprising:
- a peroxide source in the amount effective to deliver 0.01% to 5.5% of hydrogen peroxide; and
an adhesion system comprising;
a hydrophobic component comprising a silicone polymer and a silicone adhesive; and
a dental surface adhesion enhancing agent,wherein the composition when applied to the teeth is sufficiently viscous to form an adherent, continuous layer on a dental surface and deliver an effective amount of said peroxide source to a tooth surface;
wherein the peroxide source is selected from;
hydrogen peroxide;
urea peroxide, a crosslinked polyvinylpyrrolidone-hydrogen peroxide complex;
sodium perborate; and
a combination of two or more thereof; and
wherein the adhesion system further comprises an organic material selected from;
bees wax, mineral oil, a mineral oil and polyethylene blend, petrolatum, a liquid paraffin and butene/ethylene/styrene hydrogenated copolymer blend, a polyethylene wax, polyisobutene, a polyvinyl pyrrolidone/vinyl acetate copolymer;
a polyacrylate;
a shellac; and
a combination of two or more thereof;
wherein the composition has a Herschel-Bulkley rate index of less than 0.7; and
wherein the composition has a critical strain greater than or equal to 0.02.
