Description

The present invention relates to a saliva-collecting chewing gum, and more particularly to a saliva-collecting chewing gum that does not easily adhere to a denture.

In dentistry, a saliva test (saliva test) is performed to measure the properties of saliva to prevent tooth decay. At that time, the patient is asked to chew chewing gum to promote saliva secretion, and then saliva is collected.

As such a chewing gum for collecting saliva, for example, in Patent Document 1, in order to collect low-viscosity chewing gum suitable for a saliva test through which a porous membrane is passed, polyisobutylene and microcrysterin wax are added to 80 to 95% by mass and a melting point. Disclosed is a chewing gum for saliva collection containing 1 to 10% by mass of a glycerin fatty acid ester having a temperature of 65 ° C. or higher, 1 to 10% by mass of a glycerin fatty acid ester having a melting point of less than 60 ° C., and 1 to 5% by mass of an ester gum.

Japanese Unexamined Patent Publication No. 2017-067667

When the saliva test is performed using the chewing gum described in Patent Document 1, there is a concern that the chewing gum adheres to the denture worn by the patient and causes discomfort to the patient.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a chewing gum for saliva collection, which is difficult to adhere to a denture.

As a result of diligent research to achieve the above object, the present inventors have found that ester gum and vinyl acetate resin, which are usually blended in chewing gum, enhance the adhesion to dentures, and have completed the present invention. ..

That is, the present invention is a chewing gum for saliva collection, which is characterized by being composed of polyisobutylene, a plasticizer, an emulsifier and an inorganic powder.

Here, these raw materials are edible, and the plasticizer is for adjusting the hardness and smoothness of chewing gum such as microcrystalline wax and paraffin wax to improve tooth penetration. The emulsifier is for softening chewing gum or imparting smoothness, such as glycerin fatty acid ester. Further, the inorganic powder is talc, calcium carbonate or the like, and is used for turbidizing a mixture of polyisobutylene, a plasticizer and an emulsifier, or for imparting smoothness to chewing gum.

Since the chewing gum for saliva collection of the present invention does not contain ester gum or vinyl acetate resin that enhances the adhesion to the denture, but contains polyisobutylene of rubber, the adhesion to the denture can be reduced. Since the chewing gum for saliva collection of the present invention is composed of a lipophilic solid substance mainly composed of polyisobutylene and a plasticizer, when the chewing gum is contained in the mouth, the chewing gum repels saliva and is between the chewing gum and the denture. By interposing saliva in the denture, it is possible to prevent the phenomenon of adhesion to the denture from occurring.

The saliva collecting chewing gum contains 30 to 70% by mass of polyisobutylene, 20 to 60% by mass of a plasticizer, 1 to 10% by mass of an emulsifier, and 1 to 10% by mass of an inorganic powder. Can be done.

The plasticizer can be microcrystalline wax, the emulsifier can be acetylated monoglyceride, and the inorganic powder can be talc. Here, since talc is contained as an inorganic powder, not only can the mixture such as polyisobutylene become cloudy, but also the texture and shape retention of the chewing gum can be improved, and the raw materials are uniformly mixed at the time of production. It also has the effect of making it easier to visually check whether or not it is.

Further, by coating the surface with hydrogenated oil, the shape retention of the chewing gum can be enhanced and adhesion to the packaging material can be prevented. Further, the saliva collecting chewing gum can contain 3 to 8% by mass of the hydrogenated oil.

As described above, according to the present invention, it is possible to provide a chewing gum for saliva collection that does not easily adhere to a denture.

Next, an embodiment of the chewing gum for saliva collection according to the present invention will be described in detail.

The chewing gum for saliva collection according to the present invention comprises polyisobutylene, a plasticizer, an emulsifier and an inorganic powder.

Polyisobutylene is a rubber having a function of increasing the elasticity of chewing gum, preferably having a molecular weight of 37,000-500,000, particularly preferably 40,000-100,000. For example, Opanol B-10 (molecular weight: 37,000-43,000), B-12 (molecular weight: 50,000-60,000), B-15 (molecular weight: 77,000-92,000), B-50 (molecular weight: 308,000-442,000) (BASF Japan stock) (Made by company) etc. can be used.

The plasticizer is for adjusting the hardness and smoothness of chewing gum, and microcrystalline wax is preferably used. Particularly preferably, microcrystalline wax Hymic 1070 (melting point: 79 ° C.), 1080 (melting point: 83 ° C.), and 1090 (melting point: 88 ° C.) (manufactured by Nippon Sei Co., Ltd.) are used. In addition to microcrystalline wax, for example, paraffin wax and the like can be used.

The emulsifier is for softening chewing gum or imparting smoothness, and glycerin fatty acid esters such as monoglyceride, organic acid monoglyceride, and polyglyceride are used, and acetylated monoglyceride is preferably used. Particularly preferably, Poem G-002 (manufactured by RIKEN Vitamin Co., Ltd.) is used. Poem G-002 is a compound in which glycerin has an organic acid (two acetyl groups) and one lauryl group.

The inorganic powder is for turbidizing a mixture of polyisobutylene, a plasticizer and an emulsifier, and for imparting smoothness to chewing gum, and talc is preferably used. In addition to talc, for example, calcium carbonate and the like can be used.

The surface of the chewing gum may be coated with hydrogenated oil. Palm hardened oil can be used as the hardened oil, and not only palm oil-derived but also soybean, rapeseed, beef fat (head), pork oil (lard) -derived hardened oil, etc. have similar melting points and are basically tasteless. The raw material may be derived as long as it is odorless and does not adhere to the packaging material after coating. If the melting point of the hydrogenated oil is 50 ° C. or lower, the chewing gum is softened too much, and if the melting point is 70 ° C. or higher, the chewing gum is likely to crack, resulting in a crispy texture. Therefore, preferably, Unishort K (manufactured by Fuji Oil Co., Ltd.) having a melting point of 56.5 to 60.5 ° C. is used. In addition to hydrogenated oil, microcrystalline wax or the like can also be used. It is preferable to coat the surface of the chewing gum with a hydrogenated oil or the like because the shape retention of the chewing gum can be improved and adhesion to the packaging material can be prevented, but the coating with the hydrogenated oil or the like is not always necessary.

The chewing gum for saliva collection according to the present invention is produced using the above raw materials at the blending ratio shown in Table 1, and when surface coating is performed, the chewing gum and the hydrogenated oil used for the surface coating are mixed at the ratio shown in Table 2. Mix. The blending ratio of the chewing gum is more preferably 40 to 60% by mass of polyisobutylene, 30 to 50% by mass of the plasticizer, 1 to 5% by mass of the emulsifier, and 3 to 7% by mass of the inorganic powder.

Next, an example of the chewing gum for saliva collection according to the present invention will be described.

In this example, chewing gum was produced with the raw materials and blending ratios shown in Table 3, and the surface of the chewing gum was coated with hydrogenated oil based on the blending shown in Table 4 to produce chewing gum for saliva collection.

The manufacturing method will be briefly described below.

First, microcrystalline wax Hymic 1070 and 1080 (hereinafter collectively referred to as "microcrystalline wax") are put into a heating container and heated to melt the microcrystalline wax. At this time, do not burn over low heat and heat to about 90 ° C.

Next, polyisobutylene operol B12 (hereinafter, simply referred to as "polyisobutylene") is put into a heating container, stirred, and mixed with microcrystalline wax. At this time, it is preferable to add the wax while dividing it so that it can be easily mixed with the microcrystalline wax.

After the mixing of polyisobutylene and microcrystalline wax is completed, acetylated monoglyceride Poem G-002 (hereinafter, simply referred to as "acetylated monoglyceride") is put into a heating container. Then, talc is put into a heating container to make the mixture of polyisobutylene, microcrystalline wax and acetylated monoglyceride cloudy. The temperature at this time is about 100 to 110 ° C.

Here, making the chewing gum cloudy has the effect of concealing the transparency of the chewing gum and improving the appearance. Further, by mixing talc, the effect of improving the texture and shape retention and the effect of making it easier to visually confirm the uniformity at the time of manufacturing are also obtained.

The mixture of each raw material is passed through a strainer, and the filtrate that has passed through the strainer is naturally cooled to solidify. At this time, it is preferable to place the filtered material on the release film laid on the tray.

The solidified product after cooling is put into an extruder to form a rope, and the rope is formed into the size of one chewing gum by a ball breaker. This molded product is chewing gum. Then, this chewing gum is placed in a kettle and the cured oil is sprayed about 15 times with a spray device to cover the surface of the chewing gum with the hydrogenated oil, and inspection and metal detection are performed to complete the chewing gum for saliva collection.

When this chewing gum for saliva collection was used for saliva collection, no adhesion to the denture was observed, and the patient was able to collect saliva without discomfort.
