Description

Solid coating preparation for tooth whitening

The present invention relates to a tooth whitening product, and more particularly to a tooth whitening coating that exhibits an immediate tooth whitening effect.

In recent years, with the interest in whitening, as the interest in teeth whitening has increased, various types of self-whitening agents such as mouse trays, strips, nail polish, and lip glosses containing whitening ingredients have been developed.

Common self-whitening products take a few weeks and a few months to remove stains from the surface of teeth.

Without such a long time investment, instant tooth whitening products, tooth coating products and the like have been developed to temporarily hide discoloration of teeth.

These tooth coating products are mainly used in the form of a manicure and applied to the surface of the teeth, and the purpose is to coat the discolored teeth to give a gloss and beautiful finish. In addition, it has gained great popularity in the market in that a tooth whitening effect can be obtained quickly.

However, such a manicure-type tooth whitening product uses an auxiliary tool such as a brush in order to uniformly apply the manicure-type tooth whitening product due to the high viscosity of the liquid state, so that brush marks are generated at the time of application, resulting in curvature. Causes problems that can occur or cause staining.

Therefore, there is an increasing demand for a product that solves the above problems and has an excellent tooth whitening effect.

Therefore, the present invention is to solve the above problems, to provide a tooth whitening product that can be uniformly applied without leaving a stain on the tooth surface.

In addition, the tooth whitening component is evenly applied to the tooth surface to provide a whitening product that can exhibit an excellent whitening effect.

In addition, the drying time is shorter than the liquid type tooth whitening coating agent, eliminating the inconvenience of the liquid flows down and is easy to carry, to provide a whitening product for tooth coating that can be used conveniently.

The present invention provides a solid type tooth whitening coating agent to solve the above problems. In particular, the tooth whitening coating agent of the present invention is applied to the discolored portion of the tooth to provide a whitening coating agent for improved use convenience while showing an immediate whitening effect.

The tooth whitening applicator of the present invention includes a white inorganic pigment which is an effective ingredient for making the teeth look white, and is applied on the teeth by direct contact with the teeth, and is a stick type tooth whitening, characterized in that the solid type Provide a coating agent for use.

In the present invention, the coating agent forms a film on the discolored portion of the tooth to block the discolored portion of the tooth, and scatters light to show the effect of whitening of the tooth.

In particular, the present invention is characterized in that the inorganic powder particles immediately change the color of the teeth by forming a film on the teeth, rather than decoloring the teeth directly to exhibit a tooth whitening effect.

The tooth whitening applicator of the present invention has a solid form in order to stabilize the white inorganic pigment which is a tooth whitening component and increase the ease of use.

As used herein, the term "solid" is non-flowable and has a certain shape, and means, for example, the hardness measured by Fudoh Rheometer durometer of Rheo Tech Co. in the range of 120 gf to 300 gf.

The white inorganic pigment is barium sulfate, mica, white carbon, magnesium oxide, calcium oxide, aluminum oxide, talc, magnesium carbonate, barium carbonate, zinc oxide, titanium oxide, hydroxyapatite, calcium carbonate, calcium phosphate, or mixtures thereof It may be used, preferably zinc oxide, titanium oxide, hydroxyapatite, calcium carbonate, or calcium phosphate may be used, most preferably titanium oxide or in terms of teeth whitening effect and compatibility with the polymer used. Zinc oxide can be used.

The particle size of the white inorganic pigment was measured by light scattering, and the average particle size was 20 µm or less, preferably 17 µm or less, and most preferably 15 µm. It can provide and, in addition, can improve the usability in an oral cavity. The particle size of the white inorganic pigment of the present invention

In the case of containing less than 1% by weight of the white inorganic pigment, the coating agent of the present invention may be applied to the tooth thickly, the usability is not good, if it exceeds 30% by weight, there is a possibility of problems in formulation stability such as phase separation have.

The tooth whitening coating agent of the present invention includes an adhesive polymer so that the white inorganic pigment can be adhered well to the tooth surface.

As the adhesive polymer, a polymer swelled by ethanol is used, and a polymer capable of preventing dissolution by saliva can be used while helping the whitening components of the present invention to be applied to the tooth surface. Preferably, bentonite, carbopol, hydroxyethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, polyvinyl alcohol, polyvinylacetate, pectin, polyalkyl vinyl ether-maleic acid copolymer (PVM / MA copolymer), polyacrylic acid , Poloxamer 407, polyvinyl pyrrolidone-vinyl acetate copolymer (PVP / VA copolymer), polyvinyl pyrrolidone (PVP), Polyquaterium-11, hydroxypropylmethylcellulose, gelatin, alginate (Sodium Alginate ), Polyvinylacetate, ethyl cellulose, poly methyl methacrylate, methacrylic acid copolymer, methacrylic copolymer, aminoalkyl methacrylate copolymer, cellulose acetate phthalate, and polyethylene glycol Can be used, and more preferably stable mixing with white inorganic pigments, Is swelled in ethanol may be a polyvinylpyrrolidone can be used in to prevent the easily dissolved by saliva in the tooth.

The adhesive polymer may be included in an amount of 1 to 20% by weight based on the total weight of the coating agent, preferably 2 to 15% by weight, more preferably 2.5 to 10% by weight.

When the content of the polymer is less than 1% by weight, it may be difficult to stably mix between the raw materials, and when the content of the polymer exceeds 20% by weight, a problem may occur that the coating agent is hard and the coating property is not good.

The present invention may further include an oily component in order to improve the applicability on the tooth surface while maintaining a constant viscosity and hardness of the solid tooth whitening coating agent.

The oily component may include one or more waxes selected from the group consisting of candelina wax, bee wax, carnauba wax, paraffin wax, Japan wax (naphtha), ceresin, and microcrystalline wax; And

Liquid paraffin, light liquid isoparaffin, heavy liquid isoparaffin, petrolatum, n-paraffin, isoparaffin, isododecane, isohexadecane, polyisobutylene, hydrogenated polyisobutylene, polybutene, ozokerite, undecided At least one selected from the group consisting of vaginal wax, polyethylene wax, polyethylene / polypropylene wax, squalane, squalene, squalene, and polyisoprene may be used.

Preferably, candela wax may be used as an oily component for maintaining the formulation of the present invention, and more preferably, fluid paraffin may be used together with the candela wax.

In addition to the above components, the coating agent of the present invention may further include a moisturizer to improve the applicability of the coating agent.

The moisturizing agent may be glycerin, propylene glycol, butylene glycol, ceramide, polyethylene glycol, castor oil, hydrogenated castor oil, and mixtures thereof.

Water, alcohol, and the like may be used as the solvent of the present invention, and generally, all solvents used in the industry may be included.

In addition, the present invention may further include a fragrance, additives and the like within the scope that does not impair the object of the present invention.
