Description

Toothpaste Composition for Whitening Tooth Using Scoria Powder}

The present invention relates to a toothpaste composition for whitening teeth using volcanic stone clusters (scoria, Korea).

Generally, the pigmentation factor of teeth is classified into exogenous pigmentation and endogenous pigmentation. Exogenous pigmentation is caused by the deposition of food waste, tobacco, coffee, tea, sugar, etc. on the surface of teeth. It is known to occur due to the overdose of tetracyclines, aging and the like.

Tooth whitening agents are classified into abrasives that physically remove exogenous coloring, colorant dissolving agents that chemically remove exogenous coloring, and peroxides that release free radicals and even endogenous coloring.

Abrasives physically polish the surface of the teeth to produce a whitening effect by smoothing the surface. Calcium carbonate, precipitated silica, silica gel, zirconium silicate, calcium dihydrogen phosphate, aluminum silicate, etc. are commonly used. Limonene, citric acid, malic acid, malic acid, tartaric acid, glycolic acid, glutaric acid, and the like are commonly used to show a whitening effect by corrosion. However, the abrasive may cause tooth neck wear and the colorant dissolving agent may cause hypersensitive teeth.

In the case of peroxides, the whitening effect of endogenous pigmentation can be expected, but the safety of the human body is excessively controversial, and it is not compatible with the general ingredients of toothpaste, and the peroxide itself is very unstable. There is a problem of rapidly decreasing.

Conventional toothpastes are used in combination because of the limited effects and disadvantages of these tooth whitening agents.

The present invention discloses a toothpaste composition which can exhibit a tooth whitening effect using a volcanic stone cluster as an abrasive.

An object of the present invention to provide a toothpaste composition for whitening teeth using a volcanic stone cluster.

Other and further objects of the present invention will be described below.

The present inventors prepared a toothpaste composition containing 10% by weight to 40% by weight of pine powder as an abrasive and confirmed the tooth whitening effect through clinical evaluation, as confirmed in the following Examples and Experimental Examples. It was confirmed that the tooth whitening effect was excellent in proportion.

The present invention is provided based on these experimental results, and the toothpaste composition for whitening teeth of the present invention is characterized by containing volcanic stone cluster powder as an abrasive.

In the present specification, the term "scoria" refers to a porous basaltic rock having a pore volume and solid volume similar to that of a volcanic ash (less than 2 mm), volcanic gravel (lapilli (2 ~ 64mm), volcanic block (more than 64mm), and volcanic bomb. Pine mushroom can be found in the topography formed by the volcano. In Korea, it is easily found in the volcanic island of Jeju Island. Jeju pine mushroom has a variety of colors depending on its major constituents. The cluster with a high content of silicon oxide has a dark gray color, the cluster with high oxidized aluminum content has a yellowish brown or black color, and the cluster with a high content of titanium oxide and iron oxide has a reddish brown color. It is known that Jeju mushroom usually has a melting point of 1,120 ~ 1210 ℃, an absorption rate of 17.7 ~ 32.5% and a wear rate of 47.25 ~ 67.22%. The cluster that can be used in the present invention is not particularly limited to Jeju clusters, but it is preferable that the clusters are known to have excellent functionality such as far-infrared radiation, heavy metal adsorption effect, deodorizing effect, and antibacterial effect.

Although the cluster powder is contained as an abrasive in the toothpaste composition of this invention, a well-known abrasive may further be contained with cluster powder. Such abrasives include calcium carbonate, precipitated silica, silica gel, aluminum hydroxide, calcium dihydrogen phosphate, insoluble sodium metaphosphate, zirconium silicate, anhydrous calcium monohydrogen phosphate, hydrous alumina, hard calcium carbonate, heavy calcium carbonate, calcium pyrophosphate, insoluble meta Phosphate, aluminum silicate, and the like, cluster powder may be used alone or mixed with one or more of these abrasives, 1 to 60% by weight, preferably 10 to 50% by weight based on the total weight (100% by weight) of the toothpaste composition of the present invention. % May be included in the dentifrice composition of the present invention. More preferably, it can be contained within the range of 10 to 30% by weight so as to minimize the side effects of the tooth wear effect while fully exhibiting the effect as an abrasive as confirmed in the experimental example below.

Particle diameters suitable for use as a abrasive may be determined within the range of ordinary skill of those skilled in the art, but in order to be free of foreign matter such as sand and to feel refreshing when brushing, the particle size may be 30 μm or less, more preferably 20 μm or less. It is preferable. The cluster powder may be obtained by any method known in the art, such as a dry grinding method or a wet grinding method, preferably when it is obtained by a dry grinding method. It is known that the powder produced by the dry grinding method generally contains water of less than 1% (v / v), so that the particles do not aggregate and hardly reaggregate when dispersed in an aqueous medium. Because it does not.

The toothpaste composition of the present invention may contain a colorant dissolving agent, peroxide, wetting agent, foaming agent, binder, sweetening agent, preservative, active ingredient, fragrance, brightener, coloring agent, solvent, etc. which are commonly used in toothpaste according to the formulation, purpose of use, and the like. Can be.

The colorant dissolving agent is a component for chemically dissolving and removing the hydrophobic colorant attached to the tooth surface, and may be used by mixing one or more selected from the group consisting of limonene, citric acid, malic acid, malic acid, tartaric acid glycolic acid, and glutaric acid. .

The colorant solubilizer may be contained in an amount of 0.1 to 1.0% by weight based on the total weight of the toothpaste composition of the present invention. If it is less than 0.1% by weight, there is a problem that the dissolving power to the coloring material is too low, and if it exceeds 1.0% by weight, the unique taste of the solvent is felt, which is not preferable and may cause irritable teeth if used continuously. have.

Peroxides are used to whiten endogenous tooth pigmentation, and hydrogen peroxide, hydrogen peroxide, sodium peroxide, calcium peroxide, or mixtures of two or more thereof may be used. Such peroxides may be used in amounts of 0.5 to 10% by weight relative to the total weight of the dentifrice composition. When used in less than 0.5% by weight tooth whitening effect is difficult to expect, and when used in more than 10% by weight may have side effects on the gums.

When hydrogen peroxide is used as a peroxide, hydrogen peroxide has a strong acidity in the range of pH 1.8 to 3.5, so it is decomposed into water and hydrogen under basic conditions and thus is not stable. Ultra-based condensate phosphate, polyvinylpyrrolidone, polyacrylic acid, hydroxyethyl cell It is preferable to use together stabilizers such as rollose and alkylcarboxylate salts.

Wetting agents are intended to prevent the toothpaste from drying and solidifying when the toothpaste is exposed to air. Wetting agents give the toothpaste the surface shine and, depending on the type, may have a sweetening effect. As the humectant, glycerin, sorbitol solution, xylitol solution, polyethylene glycols, propylene glycol, a mixture of two or more thereof, and the like may be used, and may be used in an amount of 10 to 40% by weight based on the total weight of the dentifrice composition.

A foaming agent is a component used for the purpose of enhancing the feeling of use of the product, to help cleansing action, to quickly disperse and infiltrate other active ingredients, and to reduce the interfacial tension so that foreign substances in the oral cavity easily fall off. Examples of the foaming agent include nonionic surfactants such as polyoxyethylene sorbitan fatty acid ester, polyoxyethylene (cured) castor oil, glycerin fatty acid ester, sorbitan fatty acid ester, sucrose fatty acid ester, alkylolamide, and alkyl glucoside, and N-alkyldiae. One or more of cationic surfactants such as minoethylglycine and anionic surfactants such as sodium lauryl sulfate may be used, and may be used at 0.5 to 5.0% by weight based on the total weight of the toothpaste composition.

The binder is used for the purpose of preventing separation of the powdered solid and liquid components of the toothpaste. The binder may be any one as long as it is a water-soluble polymer. Examples thereof include sodium carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carrageenan, xanthan gum, sodium alginate, and mixtures of two or more thereof. May be used in an amount of 0.1 to 5 wt% based on the total weight of the dentifrice composition.

Sweeteners are used for the purpose of enhancing the usability, and include, for example, sodium saccharin, aspartame, stevioside, xylitol, licorice acid, mixtures of two or more thereof, and 0.05 to 5% by weight based on the total weight of the toothpaste composition. Can be used.

The active ingredient is used for the purpose of preventing tooth decay, periodontitis, suppressing plaque, and the like, for example, sodium phosphate, sodium fluoride, amine fluoride, tin fluoride, sodium monofluorophosphate, chlorohexidine, allantoin chlorohydroxy aluminate, amino Capronic acid, triclosan, cetylpyrididium chloride, zinc chloride, pyridoxine hydrochloride, tocopherol acetate, sodium bicarbonate, aminocaproic acid, allantoin, derivatives of allantoin, vitamins and the like. Such active ingredients may be used in an amount of 0.1 to 5 wt% based on the total weight of the dentifrice composition.

As the preservative, methyl paraoxyancinate, propyl paraoxybenzoate, sodium benzoate and the like can be used, and peppermint oil, spearmint oil, menthol, anetol and the like can be used. These preservatives and fragrances can be added and used in an appropriate amount (0.01 to 2.0% by weight) according to the purpose for which they are added.

Titanium oxide or the like may be used as the brightener, food coloring may be used as the dye, and purified water or ethanol may be used as the solvent.

The formulation of the dentifrice composition of the present invention will usually be prepared in ointment (ie paste) and filled into the tube for use.

As described above, according to the present invention, a toothpaste composition for whitening toothpaste using cluster powder as an abrasive can be provided.

When the cluster powder is used as an abrasive, in addition to the teeth whitening effect, the antibacterial and deodorizing effects of the cluster may also exhibit effects such as bad breath prevention and prevention.

Hereinafter, the present invention will be described with reference to Examples and Experimental Examples. However, the scope of the present invention is not limited to these examples and experimental examples.

Preservatives and fragrances were used in trace amounts.

< Experimental Example > Sensory Evaluation of Teeth Whitening and Polishing

Experimental Example 1 Teeth Whitening Effect Experiment

The gel mixture obtained by uniformly mixing cigarette dust, coffee, tea powder and sugar, which may cause exogenous pigmentation of the teeth, is placed in a container equipped with a rotating plate at the bottom, and tooth samples obtained from the next 10 to 20 healthy people After the rotating plate was fixed, the rotating plate was rotated for 72 hours to induce coloration of the tooth specimen. Thereafter, the pigmented tooth sample was dried in the shade for 2 days, and then applied to the toothbrush fixed to the axis of motion so as to allow 90 reciprocations per minute using the toothpaste compositions of the preparations and comparative examples, and the colored tooth Samples were artificially polished for 20 minutes. The whiteness was measured using a color difference meter (SZ, Nippon Denshoku) before and after the artificial polishing, and the degree of increase (ΔL) before and after polishing was shown in [Table 2].

Increase degree of whiteness (△ L) division Increase degree of whiteness (△ L) Production Example 1 28.7 Production Example 2 42.5 Production Example 3 54.3 Production Example 4 67.6

Referring to [Table 2], it can be seen that the whiteness increases in proportion to the content of the volcanic stone cluster powder.

Experimental Example 2 Experimental Evaluation of Polishing Degree of Teeth

Forty participants in their 30s to 40s were divided into four groups of 10 people, and the toothpaste composition of [Table 3] was used three times a day for three days, and the degree of polishing force was measured in the 5-point scale below. It was evaluated according to.

5 points | pieces: Very strong.

4 points | pieces.

3 points | pieces: Normal.

2 points: weak

1 point | piece: Very weak.
