As the result of making intensive investigations in view of the above-described circumstances, the present inventors have found that by using specific mica titanium for a tooth coating composition using shellac as the main body, a tooth coating composition, which does not become white turbid for a long time, has a quick drying property, and is excellent in the durability, is obtained and have accomplished the present invention.

Then, the present invention described below in detail:

Shellac used in the invention is a resin, which has actual results of being used for foods and has a very high safety. In the tooth coating composition of the invention, the shellac is used as a coat-forming component. The content of such a shellac in the total composition is preferably in the range of from 1% by weight to 20% by weight. When the content of shellac is less than 1% by weight, the coat is too brittle and thus the composition cannot be used as a tooth coating composition. Also, when the content thereof exceeds 20% by weight, the viscosity of the coating liquid is increased, whereby it becomes difficult to thinly coat the composition on teeth and also the drying property becomes inferior. The particularly preferred content of shellac is from 5% by weight to 15% by weight.

In addition to shellac as the coat-forming component, one kind or a combination of two or more kinds of other resins, high molecular materials, and dental cements can be added to the composition at a suitable amount. By adding such material(s), the preferred effects of more improving the luster of the coat and more improving the dispersion of mica titanium or pigments can be expected.

Examples of such a resin include an acrylic resin, a vinyl acetate resin, an alkyd resin, a vinyl chloride resin, a silicone resin, a fluorine resin, rosin, etc.

Examples of the high molecular material include vinylon, nylon, polyvinyl alcohol, polyvinyl pyrrolidone, polyvinyl butyral, polybutene, polyethylene, polypropylene, polyisoprene, cellulose ethers, nitrocellulose, ester gum, viscose rayon, polysaccharide, etc.

Furthermore, examples of the dental cements include zinc phosphate cement, carboxylate cement, glass ionomer cement, zinc oxide euginol cement, silicate cement, etc.

Mica titanium is a substance obtained by coating a mica powder with a thin film of titanium oxide, and fundamentally has been frequently used as a pigment but in the invention, by compounding mica titanium as a coat-strengthening agent, the tooth coating composition excellent in the durability after coating is obtained. Also, by controlling the thickness of the titanium oxide film of the mica titanium, it is possible to obtain an interference color such as yellow, red, blue, green, etc., whereby the tooth coating composition giving a good aesthetic appearance is obtained.

The compounding amount of such a mica titanium in the whole composition is preferably from 0.5% by weight to 30% by weight. When the content of mica titanium is less than 0.5% by weight, the strength of the coat is lowered and the desired durability is not obtained. On the other hand, the content thereof exceeds 30% by weight, the dispersibility thereof in the solution becomes inferior, also, not only after coating, the evaporation of the solution is delayed to reduce the drying property, but also after coating, a rough-feeling sense of incongruity occurs in the mouth. Particularly preferred compounding amount of mica titanium is from 2% by weight to 15% by weight of the whole composition.

The mean particle size of mica titanium used in the invention is in the range of preferably from 5 um to 50 um, and more preferably from 10 um to 30 um. By using the mica titanium having the mean particle size of from 5 um to 50 um, a proper hiding power is imparted to the coat and further the using feeling in the mouth is improved.

As the main solvent of the tooth coating composition of the invention, a lower alcohol-base solvent dissolving shellac is used. As the solvent, which is nontoxic to the human body and dissolves well shellac, there are ethanol, n-propanol, isopropanol, n-butanol, isobutanol, etc., and from the points of the dissolving property and the volatile property, ethanol is most preferred. In addition to the main solvent, as an auxiliary solvent, any solvent, which is safe for the human body and gives less stimulation in the mouth, may be used. For example, as an auxiliary solvent, there are water, propylene glycol, glycerol, etc. Propylene glycol and glycerol are also frequently used as the solvents for general cosmetics and are used for dissolving medical components and extracts.

To the tooth coating composition of the invention can be added a chemical having an anti-cariogenic action. As such a chemical having an anti-cariogenic action, there are sodium fluoride, sodium monofluorophosphate, stannous fluoride, and polyphenol-containing vegetable extract.

There are actual results that sodium fluoride, sodium monofluorophosphate, or stannous fluoride is properly compounded in dentifrices as a medical component having an anti-cariogenic action and many products are on the market. Also, it is known that the polyphenol-containing vegetable extract has an antimicrobial action to the S. Mutans bacteria, which is a decayed tooth bacteria, and the extract is considered to be a very effective dental carries preventing agent.

Practical examples of the polyphenol-containing vegetable extract include one or more extracts selected from the group consisting of a fig extract, a hydrangea tea extract, an oolong tea extract, a tea extract, a grape seed extract, a grape rind extract, a blue berry extract, an apple extract, a eucalyptus extract and a rosemary extract.

By compounding the above-described medicine having the anti-cariogenic action with the tooth coating composition of the invention, without making a troublesome action such as teeth polishing such as brushing, etc., the dental caries preventing effect can be expected.

Also, the tooth coating composition of the invention can, if necessary, contain various coloring agent. Examples of such a coloring agent include zinc oxide, titanium oxide, barium sulfate, mica, carbon black, white carbon, calcium hydrogenphosphate, calcium tertiary phosphate, hydroxy apatite, iron oxide, chromium oxide, magnesium oxide, calcium oxide, aluminum oxide, fish flakes, talc, calcium carbonate, magnesium carbonate, barium carbonate, and tar dyes.

Furthermore, the tooth coating composition of the invention can contain, if necessary, various pharmaceutical components other than the above-described substances and also spicery, an antiseptic, a buffer, s pH controlling agent, a surface active agent, a dispersing agent, a plasticizer, a ultraviolet absorbent, a viscosity controlling agent, an antioxidant, etc.

The pharmaceutical components include sodium azulenesulfonate, Epsilon-aminocaproic acid, allantoin, allantoin chlorohydroxy aluminum, allantoin dihydroxy aluminum, epidihydrocholestrin, dihydrocholesterol, sodium chloride, glycyrrhizinic acid, diammonium glycyrrhizinate, di-sodium glycyrrhizinate, tri-sodium glycyrrhizinate, di-potassium glycyrrhizinate, mono-ammonium glycyrrhizinate, beta-glycyrrhizinic acid, isopropyl methyl phenol, cetylpyridinium chloride, decalinium chloride, benzalkonium chloride, benzethonium chloride, alkyldiaminoethylglycine hydrochloride, chlorohexidine hydrochloride, tricrosane, ascorbic acid, sodium ascorbate, pyridoxine hydrochloride, dl-alpha-tocopherol acetate, dl-alpha-tocopherol nicotinate, zeolite, di-sodium dihydrogen pyrophosphate, sodium pyrophosphate, sodium hydrogenphosphate, sodium tertiary phosphate, sodium polyphosphate, polyethylene glycol, polyvinyl pyrrolidone, lysozyme chloride, copper chlorophyllin sodium, hinokitiol, polyoxyethylene lauryl ether, lauroylsarcosine sodium, etc.

The above-described pharmaceutical components have the actual results of being compounded with dentifrices and are preferred materials as the materials of being used in the mouth. As the pharmaceutical effects thereof, there are, in addition of the prevention of dental caries, the prevention of halitosis, the prevention of the deposition of tartar, the prevention of gingivalise.gingivitis, the effect of removing nicotine, etc.

In addition, as the dispersing agent described above, there is an N-methacrolylethyl-N,N-dimethylammoniume. alpha-N-methylcarboxybetainee.butyl methacrylate copolymer. The compound functions as a good dispersing agent.
