Description

Description: TECHNICAL FIELD The present invention relates to a granular oral composition such as a granular mouthrinse which is used by dissolving it in water at the time of use, and more specifically, it has a solubility in water. It relates to a good powdery oral composition.

Problems to be Solved by the Related Art and Invention Powdery oral compositions are used by dissolving them in water at the time of use, but powdery mouthwashes containing powdered fragrances, etc. The dissolution speed in water is slow, and it takes a few minutes to dissolve the powdered fragrance in water in a stationary state, and it cannot be used immediately. In addition, if the powdered flavor is immediately dissolved by stirring with a spoon or a stirring rod at the time of use, the stirring operation is troublesome.

Therefore, by mixing an appropriate acid or alkali into the powdered fragrance and adding water during use, gas (air bubbles) is generated due to the acid-alkali reaction. It is suggested to hasten it.

However, such a powdery oral composition in which an acid or an alkali is mixed with a powdered fragrance has a drawback that a large amount of bubbles float on the liquid surface when dissolved in water during use.

On the other hand, a bubbling cup described in Japanese Utility Model Publication No. 56-10356, in which a powdery or paste-like easily-dissolving agent is adhered to the inner surface of the cup to improve the solubility of the content of the cup, is actually used.
Gargle cup and Japanese Patent Publication Sho 58-5 described in No. 5-37662
No. 2835, a method of manufacturing a container having an adhesive layer of powder particles on the inner surface is proposed. When a powdery oral composition containing a powdered fragrance is dissolved in water using such a cup, it easily dissolves, but there is the trouble of using a special cup, and these cups are difficult to manufacture. There is a problem that it is strange.

Therefore, it has been desired to develop a powdery oral composition which has good solubility in water and can be easily used.

The present invention has been made in view of the above circumstances, and provides a powdery oral composition that can be used immediately by quickly dissolving the powdered flavor in water and easily dissolving it in water in a stationary state during use. With the goal.

Means and Actions for Solving Problems The inventors of the present invention have made extensive studies to achieve the above-mentioned object, and as a result, blend the ethyl alcohol-containing powder into the powdery granular oral composition containing the powdered fragrance. In this case, 1 part by weight or more of ethyl alcohol-containing powder having an ethyl alcohol content of 20% by weight or more is used for 1 part by weight of powdered flavor containing an oily flavor, and the amount of powdered flavor is powdered at the time of use. 0.1 parts by weight or more based on 100 parts by weight of water added to the oral composition, and the total amount of the powdered fragrance and the ethyl alcohol-containing powder is added to 100 parts by weight of water added to the granular oral composition when used. When the content of the ethyl alcohol-containing powder is 30 parts by weight or less, the dispersibility of the powdered fragrance is improved by the diffusion of ethyl alcohol when the powdered ethyl alcohol-containing powder is dissolved in water, and the speed of dissolution of the powdered fragrance in water is improved. It is found that a powdery oral composition having excellent usability that can be immediately used by being dissolved in water in a static state without stirring at the time of use is formed, and forms the present invention. Came to.

Accordingly, the present invention comprises 1 part by weight or more of an ethyl alcohol-containing powder having an ethyl alcohol content of 20% by weight or more with respect to 1 part by weight of a powdered fragrance containing an oily fragrance, and the compounding amount of the powdered fragrance at the time of use It is 0.1 parts by weight or more with respect to 100 parts by weight of water added to the powdery oral composition, and the total blending amount of the powdered fragrance and the ethyl alcohol-containing powder is 100 parts of water added to the powdery oral composition at the time of use. A powdery oral composition is provided, which is 30 parts by weight or less with respect to parts by weight.

Hereinafter, the present invention will be described in more detail.

The powdery oral composition of the present invention can be used as a powdery mouthwash or the like, and is used after adding water to dissolve it into a liquid when used.

The powdery oral composition according to the present invention contains a powdered fragrance as an essential component.

Here, there are no restrictions on the production method and components of the powdered fragrance, and various powdered fragrances can be used. In particular, an oily fragrance is emulsified and dispersed in an aqueous solution of a film substance such as gum arabic, gelatin, or dextrin. Then, a powdery fragrance obtained by coating an oily fragrance obtained by spray drying with a film substance can be suitably mixed. In this case, as the oily fragrance, specifically, menthol, carvone, anethole, eugenol,
Methyl salicylate, spearmint oil, peppermint oil,
Lemon oil, orange oil, sage oil, rosemary oil, cinnamon oil, pimento oil, laurel oil, perilla oil, winter green oil, clove oil,
Examples include eucalyptus oil, strawberry flavor, orange flavor, lemon flavor, apple flavor, banana flavor, pineapple flavor and the like. These oily flavors may be simple or may be used in combination of two or more kinds, but it is preferable to mix them in the powder flavorant so that the content is about 5 to 40% by weight.

In the present invention, the powdered fragrance may be blended alone or in combination of two or more.

Furthermore, the amount of the powdered fragrance is not particularly limited, but it may be 0.1 part by weight or more, particularly 0.25 part by weight or more based on 100 parts by weight of water added when the powdery oral composition is used. preferable. If the content of the powdered flavor is less than 0.1% by weight, the flavor may be weak.

The powdery oral composition of the present invention is obtained by adding ethyl alcohol powder to the powdery oral composition obtained by mixing the above-mentioned powdery fragrance. In this way, by mixing the powdered flavoring agent with the ethyl alcohol-containing powder together, the speed of dissolution of the powdered flavoring agent in water is increased, and if water is added during use, it can be easily dissolved in a stationary state and used immediately. An oral composition can be obtained.

In this case, as the ethyl alcohol-containing powder, various ethyl alcohol-containing powders can be used without any limitation in the production method and components thereof. Among them, a suitable amount of the coating agent such as dextrin was dissolved in the ethyl alcohol aqueous solution to obtain the powder. It is preferable to incorporate powders obtained by spray-drying the solution at the lowest possible temperature. Here, the content of ethyl alcohol in the ethyl alcohol-containing powder is preferably 20% by weight or more, and particularly preferably 27% by weight or more, and when the content of ethyl alcohol is less than 20% by weight, the dissolution speed of the powdered flavor becomes slow. There are cases.

As the ethyl alcohol-containing powder, whiskey, brandy, rum, wine or the like may be used as ethyl alcohol, and these powders may be appropriately blended.

Further, in the present invention, the ethyl alcohol-containing powder is preferably blended in an amount of 1 part by weight or more, particularly 2 parts by weight or more with respect to 1 part by weight of the powdered fragrance in the powdery oral composition.

Further, the ethyl alcohol-containing powder is such that the total amount of the powdered flavor and the ethyl alcohol-containing powder in the powdery oral composition is 30 parts by weight or less based on 100 parts by weight of water added to the powdery oral composition at the time of use. In particular, it is preferable to add 20 parts by weight or less. When the content of the ethyl alcohol-containing powder is less than 1 part by weight with respect to the content of the powder flavor, or the total content of the powder-containing flavor and the ethyl alcohol powder is more than 30 parts by weight with respect to 100 parts by weight of water added at the time of use. Then, the dissolution speed of the powdered flavor may be slowed down.

The powdery or granular oral composition of the present invention can be appropriately blended with other components usually used in oral compositions according to the purpose of use.

Other components include, for example, saccharin sodium,
Stevioside, neohesperidyl dihydrochalcone,
Sweeteners such as asparatame, legal dyes such as blue No. 1, green No. 1, yellow No. 4, yellow No. 203, citric acid, phosphoric acid,
PH adjusters such as citrate and phosphate, preservatives such as sodium benzoate, methyl paraoxybenzoate, ethyl paraoxybenzoate, etc., alkyl groups such as sodium lauryl sulfate and sodium myristyl sulfate having 8 to 18 carbon atoms Water-soluble salts of higher alkyl sulfates, foaming agents such as sodium salt, potassium salt or ethanolamine salt of N-lauroyl, N-myristoyl or N-palmitoylsarcosine, sodium carbonate, sodium hydrogen carbonate,
Bubble generating agents such as citric acid and tartaric acid, thickening agents such as sorbit, solubilizing agents such as polyoxyethylene hydrogenated castor oil and polyoxyethylene polyoxypropylene glycol, astringents such as zinc salts such as zinc chloride and zinc citrate. Agents, flavoring agents such as sodium chloride, potassium chloride, etc., rosegon, rosemary, T-shaped, chlorhexidine salt, dextranase, amylase, protease, mutanase, lysozyme, lytic enzyme, litec enzyme, sodium monofluorophosphate, sodium fluoride, Examples thereof include active ingredients such as stannous fluoride, tranexamic acid, tocopherol acetate, β-glycyrrhizinic acid, allantoins, epsilon aminocaproic acid, dihydrocholesterol, glycyrrhetin salts, glycyrrhetinic acid, and vitamins.

Effects of the Invention The powdery oral composition of the present invention is obtained by blending the ethyl alcohol-containing powder with the powdered fragrance in the above specific amount,
It is possible to improve the speed of dissolution of powdered fragrance in water, and because it can be easily dissolved in water in a stationary state without stirring with a spoon or a stirring rod, it can be used immediately by adding water at the time of use, It is very easy to use.

Further, the present invention can be applied to powdered juice and the like in the food field.

An experimental example is shown below. In the following, all parts are parts by weight.

The powdered fragrance and ethyl alcohol-containing powder used were as shown below.

Powdered fragrance Mainly composed of dextrin, to which the following fragrances and a small amount of gum arabic, gelatin and water are added.

Powder fragrance-1: Peppermint oily fragrance content 30% by weight Powder fragrance-2: Spearmint oily fragrance content 10 〃 Powder fragrance-3: Wintergreen oily fragrance content 5

27 〃 Ethyl alcohol-containing powder-4: 〃
20 〃 Ethyl alcohol-containing powder-5: 〃
14 〃 [Experimental Example 1] After preparing a powdery oral composition of the following formulation, place it in a beaker, add 100 parts of water at 25 ° C, dissolve while standing without stirring, and use the following criteria. The dissolution speed and the feeling of use (strength of flavor) were evaluated.

Method Powder Perfume-1 0.5 part Ethyl alcohol-containing powder shown in Table 1 2.0 Saccharin sodium 0.02 Dissolution speed evaluation standard ○: Dissolve within 30 seconds.

Δ: Melts in 31 seconds to 1 minute 59 seconds.

X: It takes 2 minutes or more to dissolve.

Evaluation standard of feeling of use (strength of flavor) O: Appropriate.

Δ: Slightly weak

X: Weak.

The above results are shown in Table 1.

From the results shown in Table 1, it was confirmed that the powdery oral composition containing the ethyl alcohol-containing powder having an ethyl alcohol content of 20% or more was excellent in the dissolution speed.

[Experimental Example 2] A powdery oral composition having the formulation shown in Table 2 was prepared and evaluated in the same manner as in Experimental Example 1. The results are shown in Table 2.

From the results shown in Table 2, the oral composition containing no ethyl alcohol powder at all, and the oral composition containing less than 1 part of the ethyl alcohol powder per 1 part of the powder flavor, were inferior in dissolution speed. In contrast, it was confirmed that the oral composition in which the content of the ethyl alcohol-containing powder was 1 part or more per 1 part of the powdered flavor had good dissolution speed and flavor intensity.

[Experimental Example 3] As shown in Table 3, powdery oral compositions having different total amounts of the powdered fragrance and the ethyl alcohol-containing powder were prepared and evaluated in the same manner as in Experimental Example 1. The results are shown in Table 3.

From the results shown in Table 3, the total amount of the powdered fragrance and the ethyl alcohol-containing powder dissolved in the powdery oral composition was 10
The powdery granular composition for oral use in an amount of 30 parts or less relative to 0 part had good dissolution speed and flavor intensity.

[Experimental Example 4] Powdery oral compositions having different amounts of powdered fragrance as shown in Table 4 were prepared and evaluated in the same manner as in Experimental Example 1. The results are shown in Table 4. From the results in Table 4, it is found that the powdery granular composition for oral use in which the amount of the powdered fragrance compounded is 0.1 part or more with respect to 100 parts of water for dissolving the powdery granular composition for oral use has dissolution speed and flavor intensity. Both turned out to be good.

[Experimental Example 5] With respect to the oral composition prepared by blending the components shown in Table 5, the dissolution speed was evaluated in the same manner as in Experimental Example 1, and the solubility of the perfume was evaluated according to the following criteria. The results are shown in Table 5.

It should be noted that the powdered alcohol containing oily fragrance is described in
It was prepared according to the method described in No. 8 and has an ethyl alcohol content of 27% by weight and a peppermint oily fragrance content of 8% by weight. Criteria for evaluating the solubility of fragrances ○ Dissolve uniformly in water (emulsification) × Fragrance floats on the water surface From the results shown in Table 5, even when the powdery alcohol containing the oily flavor is used, this is similar to the case where the ethyl alcohol powder containing the oily flavor is mixed, but the dissolution speed is fast, but the flavor does not dissolve (emulsify) in water. Although it floats on the water surface and its solubility is poor, the combined use of powdered fragrance and ethyl alcohol-containing powder does not cause the fragrance to float on the water surface in a short time, and the fragrance is uniformly dissolved and emulsified. It was confirmed.

[Experimental Example 6] The ingredients shown in Table 6 were blended to prepare a granular oral composition, which was placed in a beaker and the solvent (2
(5 ° C.) 100 parts was added and the dissolution speed was evaluated in the same manner as in Experimental Example 1. The results are shown in Table 6.

From the results shown in Table 6, the powdered flavor has a poor dissolution speed in any of water, a mixed solvent of water and ethanol, and ethanol, but when the powdered flavor and the ethyl alcohol-containing powder are used in combination, the powder flavor dissolves quickly in water. I found out that From this, when the powdered flavor and the ethyl alcohol-containing powder are used in combination, the fact that the powdered flavor is immediately dissolved without stirring with a spoon or the like is not due to the flavor-solubilizing effect of alcohol, but the ethyl alcohol at the time of dissolution. It was confirmed that the dispersibility of the powdered fragrance was improved and the dissolution of the powdered fragrance in water was promoted by the diffusion of.

Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited to the following examples.

In addition, all the following parts indicate weight, and the same powder perfume and ethyl alcohol-containing powder as those used in the experimental examples were used.
