[0043] Example 1 with 3% Polyacrylate Crosspolymer-6 had the strongest flavor presentation as evidenced by the largest headspace measurements. For Example 1, the average total flavor peak area was more than 30% stronger than the gel network as determined by the total flavor display test by headspace GC-MS. Example 1 gave a very good flavor presentation while using 3% flavor. Surprisingly, crosslinked polymer-6 helps both stabilize the peroxide and improve the flavor presentation, as conventional compositions for stabilizing the p...

Abstract

Oral care compositions containing a peroxide and a 2-acrylamido-2-methylpropane sulfonic acid polymers, copolymers, or cross polymers. The oral care compositions can also contain a fluoride ion sourceand a flavor.

Description

technical field [0001] The present invention relates to oral care compositions. More specifically, oral care compositions comprising a fluoride salt, a source of peroxide, a flavoring agent and 2-acrylamide-2-methylpropanesulfonic acid (AMPS) polymer, copolymer or crosslinked polymer. Background technique [0002] Oral care compositions, including dentifrice compositions, may contain fluoride salts, peroxides, abrasives, and flavors to clean teeth, freshen breath, and maintain the appearance and health of the oral cavity, including teeth and gums. [0003] Toothpastes with higher levels of peroxide (eg, greater than about 1%) may be particularly desirable in order to achieve enhanced whitening. Formulating oral care compositions with high levels of peroxides is difficult. First, peroxides can be unstable. When peroxide breaks down, it forms oxygen, water and free radicals. Excess gas can cause swelling and bursting of primary packaging, and free radicals can cause the en...
