Abstract

PROBLEM TO BE SOLVED: To obtain a stain-removing gum composition having excellent cleaning power against stain in the oral cavity, especially stain such as tea-incrustations and capable of conveniently performing cleaning at any place by adding the main base material consisting of a complex of a gelatin and a polyphenol with an abrasive. SOLUTION: This composition is composed of (A) the main base material consisting of a complex of a gelatin obtained by decomposing collagen followed by purification and a polyphenol such as gallic acid (ester) and (B) an abrasive (an average particle size is preferably 0.1-100 μm) such as precipitated silica. Further, it is preferable that the amount of the polyphenol compound to be added is 1/5 to 1/1 the net weight of the gelatin, and the amount of the abrasive is 1/10 to 1/1 the net weight of the gelatin.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excellent gum composition which can efficiently clean and remove stains in the oral cavity, particularly stains such as tea astringency, by chewing.

[0002]

2. Description of the Related Art At present, toothbrushes, dentifrices, mouthwashes, chewing gums and the like have been studied as general mouth cleaning base materials.
It is commercially available. Of these, only chewing gum, which is a type of chewing, can be easily used anywhere.
On the other hand, plaque, food residue, stain
(Colored deposits, tea astringent stains) and the like. Of these, the stains are particularly colored, so that the stains are conspicuous, and the adhesion is not preferable in terms of hygiene and aesthetics. Therefore,
It is an important issue to remove such stains effectively. Thus, the development of a gum-type oral cleaning agent which has a high oral cleaning power for stains and can be easily used anytime and anywhere is desired.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a gum composition which is excellent in cleaning ability for stains in the oral cavity, especially stains such as tea astringent, and which can be easily cleaned in the oral cavity without selecting a place of use. The task is to provide.

[0004]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, by blending an abrasive with a gum base containing a complex of gelatin and polyphenol as a main base, an oral cavity was prepared. The present inventors have found that dirt (especially stain) in the inside can be effectively removed, and have accomplished the present invention. That is, according to the present invention, a main base (A) comprising a complex of gelatin and polyphenol, and an abrasive (B)
And a gum-like composition for removing stain.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The gum-like composition base of the present invention can be made essentially of gelatin and polyphenol, and usually comprises vinyl acetate resin, tickle, polyisobutylene, polybutene, ester gum and the like. Is compositionally different from the gum base. Therefore, the method for producing the gum composition of the present invention is completely different from the usual method for producing a gum base. In other words, first dissolve gelatin in water,
A polyphenol compound previously dissolved in water is added thereto. This forms a precipitate. This is 3
By centrifuging at 000 rpm for 5 minutes to remove excess water, a target gum-like substance can be obtained. It is considered that this gum-like precipitate was formed due to the interaction between gelatin and polyphenol to form a complex, and its texture was very different from that of commercially available gum in terms of hardness, elasticity, adhesion, and cohesiveness. Very similar to When an abrasive is blended, it becomes possible by adding polyphenol to an aqueous gelatin solution in which the abrasive is dispersed in advance.

[0006] Generally, gelatin is obtained by decomposing and purifying collagen, and there are acid-treated and alkali-treated types depending on the production method. Although this difference in the production method affects the isoelectric point of gelatin and the like, the gelatin used in the present invention is not limited to the distinction between acid treatment and alkali treatment.
In addition, there are gelatins having various jelly strengths, which are not affected.

The polyphenol compounds used in the present invention are not limited to those extracted from green tea, grape seeds and the like, and are not limited as long as they have two or more phenolic hydroxyl groups. Examples thereof include gallic acid and esters thereof.
Catechin, epicatechin, galoteticine, epicatechin gallate, epigallocatechin gallate, epigallocatechin, proanthocyanidin, lignin and the like. The amount of the polyphenol compound to be added is preferably 1/5 to 1/1 based on the net weight of gelatin. When the amount of the polyphenol compound is less than 1/5 of gelatin, a sufficient amount of precipitate cannot be produced, and even when added more than 1/1, the amount of precipitate does not change. The preferred amount is 1
/ 4 to 1/1. The amount of the abrasive used in the present invention is not limited as long as it does not prevent the insolubilization of the gelatin.
/ 1 is preferable. If the amount of the abrasive is more than 1/1, the precipitation of gelatin is hindered, and the gel may not be formed well. If the amount of the abrasive is less than 1/10, a sufficient cleaning effect cannot be obtained.

As the abrasive, various conventionally known abrasives used for toothpaste and the like are used. As inorganic abrasives, for example, silica abrasives such as precipitated silica, silica gel, aluminosilicate, zirconosilicate, dibasic calcium phosphate dihydrate and anhydride, calcium pyrophosphate, calcium carbonate, aluminum hydroxide, Alumina, magnesium carbonate, tertiary magnesium phosphate,

Those having an average particle size of 100 μm are used, and those having an average particle size of 0.5 to 50 μm are more preferably used. The gum composition of the present invention has other components as required in addition to the above components, for example, a sweetener, an emulsifier, a medicinal component, a water-soluble polymer,
A pH adjuster, a dye, a fragrance and the like can be blended.
That is, these additives are dissolved or dispersed in an aqueous gelatin solution in advance, and the desired gum composition can be obtained by adding a polyphenol compound thereto. Further, after being spread into a plate shape by a roll, it can be cut into an appropriate size, and if necessary, powder can be sprinkled on the surface to suppress the adhesion of gum. Examples of sweeteners include monosaccharides such as glucose, xylose and fructose; reducing disaccharides such as maltose; non-reducing disaccharides such as sucrose and trehalose; sugar alcohols such as erythritol, lactitol, xylitol, sorbitol and maltitol; Starch hydrolyzate, stevia, aspartame, saccharin and the like are used.
