Description

Skirt composition {DENTIFRICE COMPOSITION}

The present invention relates to a skirt composition having an appropriate polishing force and having excellent usability due to the synergistic effect of the granules feeling and excellent skirt dispersibility.

The polishing force of the skirt composition is considered to be correlated with the hardness, particle diameter, and compounding amount of the abrasive to be used. That is, in abrasives, such as calcium hydrogen phosphate which are comparatively soft (Moss hardness 2-3 vicinity), what has a large particle diameter can be mix | blended with a skirt composition in comparatively large quantities. However, in the case of a relatively hard abrasive such as silicic anhydride (near Moss hardness 4 to 6) and the like, only a small amount can be blended with a small particle diameter.

On the other hand, the hardness, particle diameter and compounding amount of the abrasive have a great influence on the feel of the skirt composition. That is, the usability of the skirt composition which mix | blended the abrasive | polishing agent of a large particle diameter, and the skirt composition with many compounding quantities of abrasive | polishing agent (substantial feeling, dispersibility, etc.) is favorable. However, the feeling of use of the skirt composition which mix | blended the abrasive | polishing agent of small particle diameter, and the skirt composition with little compounding quantity of abrasive | polishing agent was bad in the subtractive feeling and dispersibility, and the improvement of the usability was calculated | required. In other words, a skirt composition comprising a large particle diameter calcium hydrogen phosphate or the like is a skirt composition having a proper polishing power and a good feeling, whereas in the case of blending an anhydrous silicic acid having a small particle diameter in the skirt composition, in order to have an appropriate polishing force, There was a need to consider improvements.

Until now, by formulating specific granules for such a skirt composition, measures have been taken to optimize the polishing force of the skirt composition and at the same time improve the usability (Japanese Patent Laid-Open No. 04-243816 and Japanese Patent Laid-Open No. 09-12436). , Japanese Patent Application Laid-open No. Hei 10-36236, Japanese Patent Application Laid-open No. Hei 10-316547). However, in these proposals, the disintegration strength of the granules to be blended is weak, and the granules are scattered and disappeared at the moment of brushing, so that it is difficult to maintain a good feeling during brushing.

In addition, when the disintegration strength of the granules is increased (Japanese Patent Laid-Open No. 2002-68947, Japanese Patent Laid-Open No. 2002-55770, Japanese Patent Laid-Open No. 2003-128528), the feeling of brushing can be maintained, but granules are similar to the abrasive. It is necessary to set the particle diameter and the compounding amount of the metal in detail to make the polishing force appropriate. In this case, when a particle diameter is enlarged and it is set as the compounding quantity equivalent to an abrasive | polishing agent, a foreign material will generate | occur | produce.

Heavy calcium carbonate is a relatively inexpensive abrasive, and its use has a merit, but since the Mohs hardness is around 3 to 4, it is a relatively hard abrasive. Therefore, in order to set a skirt composition having an appropriate polishing force, it is inevitable to reduce the particle diameter and reduce the blending amount. There was no choice but to. Therefore, the skirt composition which mix | blended heavy calcium carbonate as an abrasive | polishing feeling was bad as a feeling of feeling and dispersibility, and the improvement of the feeling of use was calculated | required.

The present invention has been made to meet such a demand, and an object of the present invention is to provide a heavy calcium carbonate-blended skirt composition having an appropriate polishing force and a good feeling.

MEANS TO SOLVE THE PROBLEM As a result of earnestly examining in order to achieve the said objective, 10-200 g / piece of collapse strength was carried out to the skirt composition which mix | blended heavy calcium carbonate which controlled the average particle diameter to 5-15 micrometers as an abrasive so that it may become suitable grinding | polishing power, By blending the water-insoluble inorganic granules having an average particle diameter of 50 to 150 µm and a difference between the 90% particle diameter and the average particle diameter of 100 µm or less, a feeling of subtraction of the dentifrice can be imparted, and at least 1 selected from the group (a) below. By dispersing the water-soluble high molecular material of the species and at least one water-soluble high molecular material selected from the following group (b) in a specific mass ratio and setting the total compounding amount in a specific range, the dispersibility of the scavenger is improved, and the sintering of the scavenger The sensation is further improved, and accordingly, it has a proper polishing power, and the feeling of using a skirt composition, a feeling of subtraction and a feeling of foreign matter is good, It was found that a skirt composition having a good feeling can be obtained.

Therefore, the present invention,

Here, as heavy calcium carbonate which is (A) component mix | blended as an abrasive | polishing agent, the thing of average particle diameters 5-15 micrometers, Preferably it is 7-13 micrometers is used. If the average particle diameter is too small, the cleaning effect of the teeth, which is a basic function of the dentifrice, cannot be sufficiently obtained, and the superior feeling of use cannot be obtained because the skirt composition is deteriorated. When the average particle diameter is too large, not only foreign matters or unpleasant feelings are generated, but also the polishing force may be too high.

On the other hand, the average particle diameter is a measured value by a microtrack (MICROTRAC) particle size distribution measuring device (Model 7995-10, Type SRA) manufactured by NIKKISO Co., Ltd., and adjusted so that the sample has a turbidity (dV value) of 0.5. It is the measured value.

As described above, the water-insoluble inorganic granules used in the present invention have a collapse strength of 10 to 200 g / piece, preferably 20 to 100 g / piece. Granules with a collapse strength of less than 10 g / piece cannot obtain excellent usability due to collapse at the start of the skirt, and granules with a collapse strength of more than 200 g / piece may cause foreign body discomfort and discomfort in the oral cavity. When the collapse strength is 20 to 100 g /, a very good feeling can be obtained from the beginning of the skirt, and the feeling is maintained during the brushing, which is a preferable range.

On the other hand, the collapse strength is an average value of the automatic breaking strength measurement values of 30 granules (a value measured when the granules are collapsed when one granule is compressed under conditions of a plunger diameter of 10 mm and a compression rate of 10 mm / min).

RDA (Radioactive Dentin Abrasion) method is a method of evaluating the abrasiveness by measuring the radioactivity of the trace amount of the wear component generated when the neutron is radiated to the missing teeth of the human, and polished using an abrasive tester. In ADA (American Dental Association), the dentin polishing value (RDA value) when calcium pyrophosphate was used as a standard substance was 100. In addition, in ADA, the upper limit of the RDA value by RDA method was made into 250 or less. In this experiment, in consideration of more safety and sufficient cleaning power, an appropriate RDA value was set to 80 to 130.

It was.

Average particle diameter and 90% particle diameter measurement method;

The average particle diameter and the 90% particle diameter were measured by adjusting the sample's turbidity (dV value) to 0.5 using a microtrack particle size distribution analyzer (NIKKISO Co., Ltd., Model 7995-10, Type SRA). (Rounded off).

In addition, the component used in the experiment example can use the component generally marketed. As heavy calcium carbonate and a water-soluble high molecular substance, the following (the same thing is used).

Heavy Calcium Carbonate:

Minutes classifier using a TC-15N manufactured turboclassifier geuppum (mean particle diameter 25μm) (the classifying conditions: classifying rotor FINE, AUTO mode, a true specific gravity of the material _{(ρ P) = 2.8g / cm} 3, the classification point _(P D) = 30.0μm, Air flow rate (Q) = 3.0M ³ / m, Rotational speed (N) = 1100rpm)

Water Soluble High Polymer (Sodium Carboxymethylcellulose):

DAICEL CHEMICAL INDUSTRIES, LTD. Manufacture CMC DAICEL 1260 Viscosity (2%, 25 ° C, BH type, No.2, 20rpm) 920mPas, Etherization degree 0.91

From the results in Table 1, in Comparative Example 2 in which the average particle diameter was increased in comparison with Comparative Example 1 in which the average particle diameter of the heavy calcium carbonate was set to 12 µm so as to obtain an appropriate polishing force, the polishing force was too high and a foreign matter was felt, which was inappropriate. In the comparative example 3 which made the diameter small, it turned out that the toothpaste feeling (dispersibility, a feeling of a loss of a feeling) is remarkably worse, and the cleaning power which is a basic function of a skirt composition cannot be obtained sufficiently. An attempt was made to improve the feeling of use by blending the granules in Comparative Example 1, but sufficient feeling of use could not be obtained with any of the granules. Among them, in comparison with Comparative Example 1, Comparative Examples 4 to 6 showed good results in feeling of subtraction in the feeling of use. In the comparative example 7, since a collapse strength was too weak, sufficient skirt composition and a feeling of subtraction were not obtained, and were unsuitable by comprehensive evaluation. In the comparative example 8, since the collapse strength was too strong, the grinding | polishing force tended to increase, and also the feeling of subtractive feeling was too strong and a foreign material felt also in the usability, and it was unsuitable in comprehensive evaluation. In the comparative example 9, since the average particle diameter was too small, sufficient skirt composition and a feeling of subtraction were not obtained, and were unsuitable by comprehensive evaluation. In Comparative Example 10, since the average particle diameter was too large, the feeling of subtraction in the feeling of use was too strong, and a foreign matter was felt, which became unsuitable in comprehensive evaluation. In Comparative Example 11, the feeling of subtraction in the feeling of use was too strong, and a sense of foreign matter was felt, which became unsuitable in comprehensive evaluation.

Experimental Example 2

Next, an improvement in the usability (particularly the skirt composition) was attempted by examining the water-soluble polymer material by using the skirt composition of Comparative Example 4 having an appropriate polishing force and no foreign matter as a good feeling of chain.

The water-soluble high molecular substances shown in Table 2 were uniformly dissolved in 3% propylene glycol aqueous solution under appropriate conditions in each water-soluble high molecular substance, a solution of 1% was prepared, and the state thereof was visually evaluated. The water-soluble polymer material that was a viscous solution was classified into a viscous polymer material and a gelled water-soluble polymer material as a gelable polymer material. As the group classification, from the results of Experimental Example 3 described later, the viscous polymer material and the xanthan gum were (a) group, and the gelable polymer material except the xanthan gum was (b) group.

In addition, as a water-soluble high molecular substance, the following commercially available thing was generally used (it is the same below).

Experimental Example 3

The dentifrice which mix | blended the components shown in Tables 3 and 4 was prepared, and the effect in the single compounding and the combination compounding of the water-soluble high molecular substance was evaluated from polishing force and usability (skirt composition, feeling of a feeling of a chain, foreign substance). The results are shown in Tables 3 and 4. In addition, the evaluation method was based on the experiment example 1.

On the other hand, the values of the mass ratio of the group (a) to the group (a) [the amount of the water-soluble polymer substance (%) of the group (b) / the amount of the water-soluble polymer substance (%) of the group (a))] are also shown in Tables 3 and 4. It was.

From the results of Tables 3 and 4, in the case of using the water-soluble high molecular substance alone, it was not possible to exceed Comparative Example 4 in the overall evaluation. By the use of the same viscous polymer material as Comparative Example 4 (Comparative Examples 12-14), the feeling of use (skirt composition) could not be improved, and comprehensive evaluation could not exceed Comparative Example 4. The use of gelling polymer materials different from Comparative Example 4 (Comparative Examples 15 and 16) caused the completion of a phenomenon, and the comprehensive evaluation could not exceed Comparative Example 4. In addition, xanthan gum of the gelable polymer material did not have water repellency and tended to be similar to that of the viscous polymer material.

When each water-soluble high molecular substance was used in combination in a ratio of 1: 1, it was as follows. In the case of viscous polymers (Comparative Examples 17, 18, 20) and gelling polymers (Comparative Examples 23), the same results were obtained as in single use.

When xanthan gum was used as the gelling polymer material and combined with the viscous polymer material (Comparative Examples 19, 21, 22), the feeling of use (skirt composition) did not improve, and the comprehensive evaluation could not exceed Comparative Example 4. Xanthan gum was classified into groups (a) and gelable polymers other than xanthan gum as group (b) from the results of single use and combination use.

On the other hand, when crosslinking type sodium polyacrylate (Examples 1 to 4) was used as the water-soluble high molecular material of the group (a) and the gelling high polymer material (Examples 1 to 4), the feeling of use (skirt composition) was improved, and the comprehensive evaluation marked the comparative example 4. This resulted in a grin. A notable result here is that there is a synergistic effect that the sublimation sensation also improves when the skirt composition is significantly improved. In the case where gelatin was used as the gelable polymer material, the feeling of use (skirt composition) was improved, and the overall evaluation resulted in exceeding Comparative Example 4.

Experimental Example 4

Next, the proper range of the mass ratio and the total compounding quantity of the water-soluble high molecular substance of group (a) and the water-soluble high molecular substance of group (b) was examined.

The skirt composition which mix | blended the components shown in Tables 5 and 6 was prepared, and the mass ratio of the water-soluble high molecular substance of (a) group and (b) group [the amount of water-soluble high molecular substance (%) / (a) group of group (b) The effect in water-soluble high molecular weight compound% (%)] was evaluated from the polishing power and the feeling of use (skirt composition, feeling of feeling of alien substance, foreign matter). The evaluation method was according to Experimental Example 1.

From the results in Tables 5 and 6, the mass ratios of the water-soluble high molecular materials of group (a) and the water-soluble high molecular materials of group (b) are preferably (a) group: (b) group = 1: 0.25-1: 3 It was. When there are too many water-soluble high molecular substances of group (a), a skirt composition worsens and comprehensive evaluation worsens, and when there are too many water-soluble high polymer substances of (b) group, it turns out that it completes a phenomenon and worsens comprehensive evaluation.

Moreover, about the total compounding quantity of the water-soluble high molecular substance of (a) group and (b) group, 0.5 to 1.5% was favorable. In the case where the total compounding amount is too large, the skirt composition deteriorates and the comprehensive evaluation deteriorates, and in the case where the total compounding amount is too small, the completion of the phenomenon occurs, and it was found that the comprehensive evaluation deteriorates.

Experimental Example 5

The kind of water-soluble high molecular substance other than what was shown in Table 2 was examined similarly to Experimental example 2. As shown in FIG.

The water-soluble polymers shown in Table 7 were classified into viscous polymers and gelatable polymers in the same manner as in Experimental Example 2, and the viscous polymers were grouped into groups (a) and gelable polymers (b).

In addition, as a water-soluble high molecular substance, the following commercially available thing was generally used (it is the same below).

The dentifrice which mix | blended the component shown in Table 8 was prepared, and the effect of the combination formulation of (b) group compounding quantity / (a) group compounding quantity of water-soluble high molecular substance 1: 1 is abrasion power, usability (a feeling of skirt composition, a feeling of a chain, Foreign matter). The results are shown in Table 8. In addition, the evaluation method was based on the experiment example 1.

From the results of Table 8, the same effects as in the case of using the water-soluble polymer material shown in Table 2 were also confirmed even when the water-soluble polymer material shown in Table 7 was used.
