Description

Compositions for oral cleaning

The present invention relates to an oral cleaning composition, in particular to a toothpaste.

Press, in modern society, in order to maintain oral hygiene and dental health, brushing teeth and gargling have become one of the living habits of modern people. In the process of brushing your teeth, you usually apply toothpaste to the toothbrush first, and then use the toothbrush to brush your teeth over and over again.

In addition, in order to improve the effectiveness of removing plaque and tartar, abrasives are usually added to toothpaste. As for the components of conventional abrasives, they are usually calcium carbonate, silica, etc.

In addition, in order to generate foam to enhance the sterilizing and cleaning effect, foaming agents are usually added to toothpaste. As for the ingredients of conventional foaming agents, they are usually sodium lauryl sulfate (SLS) or sodium lauryl ether sulfate (SLES).

However, although conventional toothpastes have the effect of removing dental plaque and tartar, the abrasive ingredients such as calcium carbonate and silica used in conventional toothpastes have high hardness, which may cause damage to teeth.

Next, as a conventional bactericide component, triclosan can be cited; however, triclosan is an environmental hormone substance. Therefore, long-term use of toothpaste containing triclosan may have adverse effects on human health.

In addition, the following non-patent documents 1 to 4 all point out that SLS/SLES, which is a component of conventional foaming agents, affects oral health. Therefore, in the present invention, it is necessary to adjust the ingredients of the foaming agent.

[Example]

Hereinafter, the present invention will be described in detail through Examples and Comparative Examples, but the present invention is not limited to these Examples and Comparative Examples.

[Examples 1 to 4 and Comparative Examples 1 to 4]

First, Examples 1 to 4 and Comparative Examples 1 to 4 were prepared using commercially available components, using conventional methods for producing oral cleaning compositions, and according to the proportions in Table 1 and Table 2 below, and each was implemented. The total weight of the examples and comparative examples is 100 g (grams). In addition, the particle size (median particle size) of the cellulose used in each of the following examples and comparative examples is 50±10 μm. The particle size (median particle size) of the microcrystalline cellulose used in the following examples and comparative examples is 100±20 μm.

Moreover, as for the manufacturing method of the conventional oral cleaning composition, for example, pure water, a preservative, a sweetener, a humectant and optional plant powder are mixed and stirred at room temperature (about 10 ~30 minutes) until the powder is completely dissolved, then add thickener and abrasive and mix and stir (about 30~60 minutes) until the surface is smooth and grain-free, finally add foaming agent and stir (about 5~10 minutes), etc.

[Table 2]

First, the composition for oral cleaning prepared by the composition disclosed in Examples 1 to 4 of Table 1 above will not be too hard (too solid) or too thin because the proportion of water is within the scope of the present invention. . Therefore, the oral cleaning compositions of Examples 1 to 4 showed suitable usage conditions under visual observation.

In addition, the composition for oral cleaning produced by the composition disclosed in Examples 1 to 4 of Table 1 above can obtain an appropriate polishing effect because the proportion of the abrasive is within the range of the present invention. Therefore, after long-term use (brushing twice a day for six months), no damage to tooth enamel or insufficient abrasive cleaning effect was observed.

Furthermore, in Examples 1 to 2, chlorella powder is added, and because it is rich in protein, polysaccharides, vitamins, minerals, amino acids, etc., it can help detoxify and improve immune function.

Furthermore, in Example 4, by using cellulose and microcrystalline cellulose together as an abrasive, the grinding and cleaning functions can be further achieved.

Next, as for Comparative Example 1, because the water content is too much (more than 50% by weight) and the abrasive content is too little (less than 10% by weight), the oral cleaning composition of Comparative Example 1 is too thin and the abrasive effect is insufficient. .

Furthermore, in Comparative Example 2, although the proportion of the abrasive is within the range of the present invention, the water content is too high (more than 50% by weight), so the oral cleaning composition of Comparative Example 2 may be too thin. .

In addition, in Comparative Example 3, although the proportion of water is within the range of the present invention, because the content of the abrasive is too high (more than 35% by weight), the viscosity during the sample manufacturing process is too high and it is difficult to use.

In addition, in Comparative Example 4, although the proportion of water is within the range of the present invention, the content of the abrasive is too small (less than 10% by weight), so an insufficient polishing and cleaning effect was observed.

The oral cleaning composition of the present invention can reduce the damage to teeth caused by use and can be recycled. Moreover, because the components (especially abrasives) in the oral cleaning composition can be completely decomposed, it can achieve environmentally friendly effects. .

The present invention is not limited to the above-described embodiments, and various changes can be made within the scope indicated in the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the present invention. within the technical scope.
