Description

[Detailed Description of the Invention] The present invention is a base material for oral compositions used in toothpastes, prophylactic pastes, etc., cleaning abrasives for daily miscellaneous goods, and industrial abrasives. Regarding polishing substrates used as various abrasives, etc., in more detail, they have low abrasiveness, so they do not easily damage the surface of the object to be polished, and have excellent dirt removal power and dirt removal efficiency, and high cleaning power. Regarding polishing base material.

In general, IJL is about to grow into a new age.
The base materials for oral compositions used in toothpastes, profilakis pastes, etc., are free from stains, plaque, food particles, etc. that adhere to the teeth.
It has a high ability to efficiently remove deposits by physical action, has excellent cleaning ability, and has mild abrasiveness that does not damage tooth enamel, and removes plaque and tartar deposits. Something that can prevent this is desirable. In this case, the cleaning function can be improved by increasing the abrasive power of the base material, but if the abrasive power is too high, there is a risk of damaging the tooth surface, so the base material should be low abrasive and have a high cleaning function. Preferably.

In view of these points, the present applicant previously proposed a specific calcium hydrogen phosphate anhydrate as a base material for oral compositions having a low abrasive and high cleaning function (Japanese Patent Application Laid-Open No. 59-2192
13-219216).

However, calcium hydrogen phosphate according to the above proposal
Anhydrous products have excellent low-polishing and high-cleaning properties and are very effective as base materials for oral compositions, but there is a need for various base materials for oral compositions that have low-polishing and high-cleaning properties. Ru.

In particular, the cleaning power of calcium hydrogen phosphate dihydrate, which has been widely used as a base material, is proportional to the polishing power, and this calcium hydrogen phosphate dihydrate has the highest polishing power. Because it is a soft abrasive with low abrasiveness, it may not have sufficient tooth surface cleaning and whitening effects if the tooth brushing method or tooth brushing time is inappropriate. Therefore, it provides a high cleaning effect while maintaining low abrasiveness. Calcium hydrogen phosphate 2
Hydrates are desired. In addition, this is particularly effective for oral cavity cleaning in patients with carillary regression, dentin exposure, and hypersensitivity of cuneiform defects. In other words, with the recent trend of aging society, such gingival recession has recently occurred.

The number of people with exposed dentin or wedge-shaped defects is increasing, and there is a growing concern about sensitivity to tooth sensitivity.However, when it comes to oral cleaning for such unhealthy people, conventional brushing with only a toothbrush or brushing with extremely low abrasive toothpaste has been used. is being carried out. However, with these brushing methods, the polishing power is insufficient and the cleaning power is also proportionally low, so a satisfactory tooth cleaning effect cannot be obtained. Therefore, even with low polishing power, a sufficient cleaning effect can be obtained. Polished base material.

In particular, there is a strong demand for calcium hydrogen phosphate dihydrate base materials.

Calcium hydrogen phosphate dihydrate is also used as a cleaning and abrasive base material for abrasives for daily miscellaneous goods such as kitchen detergents and cleansers, and industrial abrasives for polishing metals, plastics, lenses, etc. However, as mentioned above, calcium hydrogen phosphate dihydrate is a relatively mild abrasive base material, and its abrasive power is small, so its stain removal effect is proportional to that. small.

In this regard, the applicant has previously proposed using calcium hydrogen phosphate anhydrate, which has specific properties, as a cleaning and polishing base material in view of its low abrasiveness but high stain removal ability. (Japanese Unexamined Patent Publication No. 188496/1983) is desired to improve the cleaning effect of calcium hydrogen phosphate dihydrate, which is a milder polishing base material.

The present invention was developed in view of the above circumstances, and has low abrasiveness and high cleaning function, and therefore enables efficient stain removal with less damage to the surface of the object to be polished. It is an object of the present invention to provide a calcium hydrogen phosphate-based polishing substrate having excellent low-abrasive and high-cleaning functions, which can be suitably used as a substrate for various uses such as daily goods and industrial use.

In order to achieve the above object, the inventors of the present invention have carried out intensive studies and found that condensed phosphoric acid or a salt thereof is used as a crystallizing agent in an equimolar neutralization reaction between phosphoric acid and a calcium compound. It has been found that calcium hydrogen phosphate obtained by adding aluminum phosphate or iron phosphate has good low-abrasive and high-cleaning properties.

That is, it has been known that calcium hydrogen phosphate is produced by equimolar neutralization reaction of phosphoric acid and a calcium compound, and condensed phosphoric acid or its salt is used as a crystal modifier in this neutralization reaction. It is also known that calcium hydrogen phosphate anhydrate obtained by using condensed phosphoric acid or its salt as a crystal modifier can be used as a base for oral compositions having a low abrasive and high cleaning function. It is also known that it can be used as a material (see the above-mentioned publication), but the present inventors further determined that during the equimolar neutralization reaction between phosphoric acid and a calcium compound using condensed phosphoric acid or its salt as a modifier, Calcium hydrogen phosphate dihydrate obtained by adding aluminum phosphate or iron phosphate has a low abrasive and high cleaning function that is not found in conventional calcium hydrogen phosphate dihydrate base materials. However, compared to conventional calcium hydrogen phosphate dihydrate, if the abrasive power (amount of wear) is the same, it will show greater cleaning power (contamination removal power), and if the cleaning power is the same, has the effect of showing lower wear amount,
Therefore, this calcium hydrogen phosphate dihydrate can be used as a base material for oral compositions, and although it has a low abrasive power, it exhibits a much superior cleaning effect than conventional products. It has been found that it can be suitably used for cleaning the oral cavity of people with hypersensitivity to defects, and that it also has excellent effects as a cleaning and polishing base material for daily miscellaneous goods and industrial abrasives. In addition, calcium hydrogen phosphate anhydrate obtained by adding aluminum phosphate or iron phosphate as described above is equivalent to or superior to the low-abrasive and high-cleaning calcium hydrogen phosphate anhydrate proposed above. It was discovered that the present invention has the above-mentioned low polishing and high cleaning functions.

The present invention will be explained in more detail below.

As described above, the calcium hydrogen phosphate polishing base material of the present invention is produced by adding condensed phosphoric acid or a salt thereof as a modifier in the equimolar neutralization reaction between phosphoric acid and a calcium compound, as well as aluminum phosphate or a salt thereof.

There may be cases where calcium oxyhydrogen cannot be obtained. There is no problem even if the concentration exceeds 10%, but the effect does not change even if it exceeds 10%, so the maximum concentration is 10%.
