The composition is thereby effective. The adjustment of the content of the coral powder enables to produce two kinds of the compositions comprising a composition used for brushing teeth before going to bed and mainly purposing the prevention of dental caries and a composition used for brushing the teeth before going out and mainly purposing etiquette.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a toothpaste composition containing an abrasive containing coral powder.

[0002]

2. Description of the Related Art Conventionally, various compositions for brushing teeth have been proposed, most of which decompose plaque formed on the tooth surface by oral bacteria, food residues, and salivary organic acids. , Or to prevent caries by removal.

Generally, in dental caries, the concentration of salivary organic acid in the dental plaque is increased by ingesting sugar, and the pH of the dental plaque is increased.
It is said that it is caused by demineralization of teeth due to a decrease in the.

Conventional toothpaste compositions contain a weakly alkaline component such as calcium carbonate as an abrasive, which neutralizes saliva organic acid in plaque during tooth brushing,
The pH of dental plaque can be increased to some extent.

[0005]

However, it is difficult to completely remove oral bacteria, food residues, and plaque by ordinary tooth brushing. Therefore, in the case of conventional weakly alkaline components such as calcium carbonate having a low neutralizing ability, in the short period of time from the start of brushing until the rinsing of the oral cavity is performed and the dentifrice composition is washed away, the remaining plaque is removed. It cannot neutralize salivary organic acids and increase the plaque pH sufficiently. Therefore, it is not possible to sufficiently prevent caries.

The present invention was devised under the circumstances described above, and even if the plaque formed on the tooth surface was not sufficiently removed by brushing the teeth, It is an object of the present invention to provide a tooth brushing composition that can sufficiently neutralize salivary organic acids in plaque during a short period of time during tooth brushing operation and that can effectively prevent tooth decay. .

[0007]

DISCLOSURE OF THE INVENTION In order to solve the above-mentioned problems, the present invention takes the following technical means.

That is, according to a first aspect of the present invention,
10 to 60% by weight of abrasive containing 3 to 20% by weight of coral powder, 0.1 to 5% by weight of binder, and 10 to 7
A dentifrice composition comprising at least 0% by weight of a humectant is provided.

According to a second aspect of the present invention, 10 to 60% by weight of an abrasive containing 3 to 20% by weight of coral powder, 0.1 to 5% by weight of a binder, 70% by weight wetting agent, 1-3% by weight foaming agent, 0.1-1% by weight
Sweetener, 0.5-2% by weight of flavoring agent, 0.1-1
There is provided a dentifrice composition comprising at least a weight percent preservative.

According to a third aspect of the present invention, 30 to 50% by weight of an abrasive containing 3 to 20% by weight of coral powder, 0.5 to 3% by weight of a binder, 40% by weight wetting agent, 1-3% by weight blowing agent, 0.1-1% by weight
Sweetener, 0.5-2% by weight of a flavoring agent, 0.1-1
% By weight of a preservative.

In any of the toothpaste compositions described above, the abrasive contains coral powder. The main component of the coral powder is calcium carbonate, which additionally contains minerals such as iron and magnesium. It has been confirmed by the present inventor that the dispersion of coral powder has an excellent neutralizing ability with respect to acid as compared with the dispersion of calcium carbonate having the same concentration (% by weight) (details will be described later). .

As described above, it is said that the cause of tooth decay is that the concentration of salivary organic acids in plaque formed on the tooth surface increases due to sugar intake and the like. In the toothpaste composition of any of the above-mentioned composition, even if the concentration of salivary organic acid is increased by ingesting sugar, during the short period of time during the brushing operation due to the excellent neutralizing ability of the coral powder, It can neutralize saliva organic acids in plaque more effectively than conventional compositions for brushing teeth. Therefore, it is possible to avoid tooth demineralization due to an increase in salivary organic acid in dental plaque, that is, generation of caries.

[0013] Further, since the coral powder is porous, the food residue, plaque and salivary organic acid are adsorbed and removed by the coral powder by utilizing its excellent adsorption ability, so that the toothpaste composition can be washed. The effect is expected to be enhanced.

Further, since the coral powder contains a large amount of minerals, it can be expected that the damaged portion of the tooth surface will be repaired.

According to a fourth aspect of the present invention, 10 to 60% by weight of an abrasive containing 3 to 8% by weight of coral powder, 0.1 to 5% by weight of a binder, and 10 to 10% by weight of a binder. 70% by weight wetting agent, 1-3% by weight blowing agent, 0.1-1% by weight
Sweetener, 0.5-2% by weight of flavoring agent, 0.1-1
A dentifrice composition can be provided that comprises at least wt% preservative and from 2 to 10 wt% sodium chloride.

According to a fifth aspect of the present invention, 10 to 15
10-60% by weight abrasive containing 0.1% by weight coral powder, 0.1-5% by weight binder, 10-70% by weight
Humectant, 1-3% by weight of a foaming agent, 0.1-1% by weight of a sweetener, 0.5-2% by weight of a flavorant,
A dentifrice composition can be provided that includes at least 1% by weight of a preservative and 2 to 10% by weight of sodium chloride.

Since the toothpaste compositions according to the fourth and fifth aspects contain coral powder in the same manner as the toothpaste compositions according to the first to third aspects, they contain the above-mentioned coral powder. Therefore, various effects can be enjoyed.

The toothpaste composition according to the fourth aspect is
The content of coral powder is relatively small,
The toothpaste composition according to the aspect of the present invention has a relatively high content of coral powder. In this way, by adjusting the content of the coral powder, it is possible to selectively use for brushing before bedtime for the purpose of preventing caries and for brushing before going out for the purpose of etiquette.

Further, since the toothpaste compositions according to the fourth and fifth aspects contain sodium chloride, a gum tightening effect can be expected.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION As described above, the present invention has three
Toothpaste composition containing at least 10 to 60% by weight of an abrasive containing 20% by weight of coral powder, 0.1 to 5% by weight of a binder, and 10 to 70% by weight of a wetting agent. Is provided. Needless to say, the content of the coral powder is not a ratio with respect to the total weight of the abrasive, but is a ratio with respect to the total weight of the toothpaste composition.

The coral powder used in the present invention comprises:
It is generally available on the market, for example, "HC
It can be purchased from Harada Service Co., Ltd. under the product name of "C". In addition, living corals are subject to protection,
The coral powder mentioned here is a finely processed coral carcass and does not pose a problem in terms of environmental protection.
Rather, it has been known that leaving the coral carcasses absent from the reproduction and growth of live corals, and in that sense, effective use of coral carcasses should be recommended for environmental protection.

Here, the neutralizing ability of the coral powder used in the present invention will be considered. The present inventor has conducted neutralization titration of citric acid using heavy calcium carbonate and light calcium carbonate which are generally used as abrasives for toothpaste compositions, and coral powder (“HCC” described above) used in the present invention. Was done. Specifically, 0.1% by weight
100 ml of an aqueous citric acid solution (pH = 2.8) of 1% by weight was used to neutralize each of them with 1% by weight of a heavy calcium carbonate dispersion, 1% by weight of a light calcium carbonate dispersion, and 1% by weight of a coral powder dispersion. The neutralization ability of each of the dispersions was determined based on the titer of each of the dispersions required to neutralize the citric acid. The end point of the neutralization titration here is
It refers to the time when the pH of citric acid reaches 7.

The results of the neutralization titration of citric acid with each of the above dispersions are shown in Table 1 below.

[0024]

[Table 1]

As shown in Table 1, 1% by weight of a heavy calcium carbonate dispersion necessary to neutralize 100 ml of a 0.1% by weight aqueous citric acid solution (pH = 2.8) was added. The amounts of light calcium carbonate dispersion and 1% by weight coral powder dispersion were 42 ml, 41 ml and 23 ml, respectively.

As is clear from the above, the coral powder dispersion used in the present invention is remarkably superior to the dispersion of heavy calcium carbonate and the dispersion of light calcium carbonate which are widely used as abrasives. High neutralization ability.
Therefore, a toothpaste composition containing coral powder,
It is possible to more effectively reduce the concentration of salivary organic acids in plaque as compared with the conventional dentifrice composition, that is, to increase the pH.

[0027] Therefore, even if the concentration of salivary organic acids in plaque increases due to ingestion of sugar, the composition for tooth brushing of the present invention can be used during the brushing operation due to the excellent neutralizing ability of coral powder. In a short period of time, salivary organic acids in plaque can be more effectively neutralized as compared with conventional toothpaste compositions. Therefore, demineralization of teeth due to an increase in saliva organic acids in dental plaque, that is, generation of caries, can be avoided as much as possible.
