Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composition for oral cavity which exerts a breath odor removing effect by blending a willow extract or a pulverized product.

[Conventional technology and problems]

Conventionally, there are many sources of bad odors in the living environment, and it is desired to suppress or eliminate them, but one of the bad odor sources is to suppress and eliminate bad breath. . As for the oral deodorant, hydrogen sulfide, methyl mercaptan, etc. are the main causative components of the bad odor of halitosis, so it has a deodorizing effect on such sulfur compounds and is put into the mouth. Therefore, it must be harmless to the human body.

[Means for solving problems]

The present inventors, in view of such circumstances, as a result of screening various plants as a natural product additive, Salix and its extract exhibit an excellent deodorizing effect on sulfur compounds such as the above compounds, It was found that the addition of the above to the composition for oral cavity is effective in preventing halitosis and preventing periodontal disease.

That is, the present invention is a toothpaste, moisturized toothpaste, toothpaste such as powdered toothpaste, oral pasta, troche, oral composition such as mouthwash tablet (however, chewing gum and candy are excluded) in the oil extract or It is a mixture of pulverized products.

The willow bud described here is a pungent variety belonging to the Polygonaceae family, and among them, a fully grown one is preferable. Examples of the cultivar of Willow Polygonum include Red Polygonum, Purple Polygonum, and Hirohamra Polygonium.

The whole plant of the above-mentioned fresh willow tree can be pulverized as it is, or it can be ground in a mortar and used as a composition for the oral cavity, but the fresh willow tree can be naturally dried or heated up to about 70 ° C. The dried product may be pulverized and used. In the case of drying, applying high heat of 70 ° C. or higher is not preferable because the active ingredient in willow tree may be decomposed.

Willow tree extract can also be used as an oral composition. In this case, the extraction is carried out using water or / and a hydrophilic organic solvent, for example, a lower alcohol such as methanol, ethanol or isopropanol, or a ketone such as acetone or methyl ethyl ketone, to extract fresh or dried whole willow grass. From the viewpoints of extraction efficiency, easiness of concentration, etc., it is most appropriate to use methanol as the extraction solvent. When the dried willow tree is heated and refluxed with about 10 times amount of methanol for 1 hour, the willow tree extract (excluding the extraction solvent) is obtained with a yield of about 10% (W / W).

The willow extract (without extraction solvent) is a dark green viscous substance with a grassy odor, and has a pungent taste when contained in the mouth like fresh or dried willow extract. It is considered that this is due to terpenes such as polygodial which is considered to be a deodorant component in willow tree.

The present inventors, in developing an oral composition containing Salix radix as an active ingredient, have studied the flavor characterized by the stimulating taste while maintaining the characteristics relating to the deodorizing effect of the ingredient having the stimulating taste, Was completed.

The amount of willow deer or its extract, which is the deodorant substance of the present invention, in the oral composition can be variously changed depending on the intended effect, etc., but 0.01 to 10% (% by weight, in the total oral composition).
The same applies hereinafter), particularly preferably 0.02 to 5%. If the content is less than 0.01%, the appearance of moderate irritating taste and deodorant effect cannot be obtained, and if it is more than 10%, the irritating feeling becomes excessive, which may reduce the good flavor. Not preferable.

As the other component of the present invention, an appropriate component depending on the type of oral composition is used. For example, in the case of toothpaste, dibasic calcium phosphate dihydrate and anhydride, calcium carbonate, calcium pyrophosphate, calcium sulfate,
Abrasives such as insoluble sodium metaphosphate, amorphous silica, crystalline silica, aluminosilicate, aluminum hydroxide, aluminum oxide, resin (the compounding amount is usually 20-60
%), Carboxymethyl cellulose, hydroxyethyl cellulose, alginate, carrageenan, gum arabic, polyvinyl alcohol, and other binders (0.3 to 5%),
Polyethylene glycol, sorbitol, glycerin,
Thickeners such as propylene glycol (10-70%), sodium lauryl sulfate, sodium dodecylbenzene sulfonate, hydrogenated coconut fatty acid monoglyceride sodium monosulfate, sodium lauryl sulfoacetate,
Foaming agents (0.1-5%) such as sodium N-lauroyl sarcosinate, N-acyl glutamate, lauryl diethanol amanide, sucrose fatty acid ester, and essential oils such as peppermint and spearmint, 1-menthol, carvone, eugenol, A perfume such as anethole and other perfume, saccharin sodium, stepioside, neohesperidyl dihydrochalcone, glycyrrhizin, perillartine, sweeteners such as p-methoxycinnamic aldehyde, preservatives and other ingredients are mixed with water and produced according to a conventional method. . Further, also in the mouthwash, the components suitable for the properties of the product are appropriately mixed.

In the present invention, lysozyme chloride, textranase, in addition to the ground product of Salix radix or its extract,
Lytic enzyme, mutanase, chlorhexidine, sorbic acid, alexidine, hinokitiol, cetylpyridinium, alkylglycine, alkyldiaminoethylglycine salt, allantoin, ε-aminocaproic acid, tranexamic acid, azulene, vitamin E, sodium cenofluorophosphate, sodium fluoride , Stannous fluoride, water-soluble first or second phosphate, quaternary ammonium compound,
An active ingredient such as sodium chloride can also be added.

The ground aroma of fragrant spices, such as peppermint, does not deodorize.

〔The invention's effect〕

The oral composition containing the willow extract or pulverized product thus obtained has a unique pungent taste of terpenes such as polygodial, and also has a breath odor eliminating effect derived from these compounds. Also, the active ingredient of the present invention is actually
Since it is Salix radix or an extract thereof that is used for food, it is an unprecedented oral composition having extremely high safety and having safety, unique flavor, and deodorant effect.
