Abstract
Existing tooth-attachable patches can be hard to remove completely by brushing of teeth. Herein described is a patch (1) when used for attaching to teeth or a surrounding part of teeth. The patch includes a drug layer for delivering drugs to teeth; and a backing layer (20) positioned on the opposite side of a tooth attachment surface of the drug layer (10). The patch also includes both a water-soluble polymer and a water-insoluble polymer and wherein the backing layer is degradable by tooth brushing and wherein a breakable portion is formed on the backing layer, and the breakable portion includes prominence and depression or bubbles (32).
Claims (12)
1. A patch for attaching to teeth or a surrounding part of teeth, which comprises: a drug layer for delivering drugs to teeth; and a backing layer positioned on the opposite side of a tooth attachment surface of the drug layer, and including both a water-soluble polymer and a water-insoluble polymer, wherein the backing layer is degradable by tooth brushing, a breakable portion is formed on the backing layer, and the breakable portion includes prominence and depression or bubbles.
2. The patch for attaching to teeth or a surrounding part of teeth of claim 1, wherein the water-soluble polymer comprises at least one selected from the group consisting of polyalkyl vinyl ether-maleic acid copolymer, polyvinyl alcohol, polyacrylic acid, poloxamer 407, polyethyleneoxide, polyvinyl pyrrolidone-vinyl acetate copolymer, polyvinyl pyrrolidone, polyquaternium-11, polyquaternium-39, carboxypolymethylene, hydroxypropyl methylcellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, starch, gelatin, and sodium alginate.
3. The patch for attaching to teeth or a surrounding part of teeth of claim 2, wherein the water-soluble polymer is hydroxypropyl methyl cellulose, polyvinyl pyrrolidone or a mixture thereof.
4. The patch for attaching to teeth or a surrounding part of teeth of claim 1, wherein a weight ratio of the water-soluble polymer and the water-insoluble polymer included in the backing layer (water-soluble polymer : water-insoluble polymer) is 1:4 to 4:1.
5. The patch for attaching to teeth or a surrounding part of teeth of claim 1, wherein the drug layer comprises at least one selected from the group consisting of ingredients for whitening teeth, ingredients for preventing or improving sensitive teeth, ingredients for preventing cavities, and ingredients for preventing periodontal disease.
6. The patch for attaching to teeth or a surrounding part of teeth of claim 5, wherein the ingredients for whitening teeth are: at least one peroxide selected from the group consisting of hydrogen peroxide, carbamide peroxide, calcium peroxide, sodium percarbonate, sodium perborate, tetrasodium pyrophosphate peroxidate and a mixture thereof; at least one polyphosphate selected from the group consisting of tetrasodium pyrophosphate, sodium acid pyrophosphate, sodium hexametaphosphate, sodium tripolyphosphate, sodium potassium tripolyphosphate, tetrapotassium pyrophosphate, ultra- metaphosphate as ultra-phosphate, acidic sodium polyphosphate, and a mixture thereof; or a mixture thereof, wherein the ingredients for preventing or improving sensitive teeth or cavities are at least one selected from the group consisting of strontium chloride, calcium carbonate, sodium citrate, sodium fluoride, silica, hydroxyapatite, potassium nitrate, and potassium phosphate, wherein the ingredients for preventing periodontal disease are at least one selected from bamboo salt, titrated Extract of Zea Mays L. unsaponifiable fraction, policresulen, tetracycline, chlorhexidine gluconate, cetyl pyridinium chloride, sanguinarine, triclosan, Magnoliae Cortex, Centella Asiatica, Chamomile, Rhatany, Myrrha, Mori Cortex Radicis, Cimicifugae Rhizoma, Green tea, Glycyrrhizae Radix et Rhizoma, Scutellariae Radix, Taraxaci Herba, and Lonicerae Flos.
7. The patch for attaching to teeth or a surrounding part of teeth of claim 1, wherein the prominence and depression has a concave portion in a depth of more than 0 µm and 30 µm or less based on a convex portion.
8. The patch for attaching to teeth or a surrounding part of teeth of claim 1, wherein the prominence and depression has a concave portion in a width of more than 0 mm and 0.1 mm or less.
9. The patch for attaching to teeth or a surrounding part of teeth of claim 1, wherein the patch comprises: a drug layer for delivering drugs to teeth; and a backing layer positioned on the opposite side of a tooth attachment surface of the drug layer, and including a water-insoluble polymer and hydroxypropyl methyl cellulose (HPMC); and wherein the water-insoluble polymer is at least one selected from the group consisting of cellulose acetate phthalate, shellac, polyvinyl acetate, ethyl cellulose, polymethyl methacrylate, methacryloyl ethyl betaine/methacrylate copolymer, methacrylic acid copolymer, and aminoalkyl methacrylate copolymer.
10. The patch for attaching to teeth or a surrounding part of teeth of claim 9 wherein the water-insoluble polymer is ethyl cellulose.
11. The patch for attaching to teeth or a surrounding part of teeth of claim 9, wherein a weight ratio of the water-insoluble polymer and the HPMC included in the backing layer of the patch (water-insoluble polymer : HPMC) is 1:0.2 to 4.
12. The patch for attaching to teeth or a surrounding part of teeth of claim 9, wherein a dry weight of the residue of the patch filtered through a 500 µm mesh after brushing the patch for 3 min at a rate of 90 times per min back and forth at a load of 250 g is less than 5 wt% based on the total weight of the patch before brushing.
