Patent ID: 8911712

Claim:
A substantially anhydrous single-part dentifrice consisting essentially of: a) re-mineralization component comprising a soluble or partially soluble calcium salt, and at least one water-soluble phosphate salt selected from the group consisting of potassium, sodium or ammonium orthophosphate, monopotassium phosphate, dipotassium phosphate, tripotassium phosphate, monosodium phosphate, disodium phosphate, trisodium phosphate, monobasic-calcium orthophosphate, and mixtures thereof; b) a teeth whitening component comprising an oxygen generating compound; c) at least one alkaline metal bicarbonate; and d) a substantially anhydrous and orally acceptable carrier, that is an ethylene oxide/propylene oxide block copolymer of the formula: HO(C 2 H 4 O/C 3 H 6 O) a (C 2 H 4 O/C 3 H 6 O) b C 2 H 4 O/C 3 H 6 O) c (C 2 H 4 O/C 3 H 6 O) b (C 2 H 4 O/C 3 H 6 O) a H wherein per mole of such copolymer there are a total of about 25 to about 50 moles of ethylene oxide units and about 5 to about 11 moles of propylene oxide units, and said copolymer has a molecular weight of from about 1250 to about 3000 in an amount of about 33 wt. % to 40 wt. % of said dentifrice; e) a nonionic surfactant that is a PEG/PPG-116/66 copolymer in an amount of 0.05-5 wt. % of said dentifrice; f) a fluoride compound; g) a sulfonated or sulfated anionic surfactant; and h) a thickener.
