Abstract
Description
【０００１】
【発明の属する技術分野】この発明は、口臭抑制を目的とする口腔衛生品に関し、具体的には、ウンデシレン酸エステルによる持続性のある口臭抑制口腔衛生品組成物に関する。
【０００２】
【従来の技術】
従来の技術によれば、口臭抑制歯磨剤には虫歯を防ぐ、歯を白くする、歯垢を除去する、口中を浄化する、口臭を防ぐ、歯のヤニを取る、歯石の沈着を防ぐ等が単一で求めたもの、または歯の洗浄効果だけを持ったもの、及び両方の効果をかね備えたものがある。口腔中に存在するグラム陰性嫌気性細菌であるフソバクテリウムニユウクレアテイム、バクテロイデスジンジバリスなどが産生する硫化水素、メチルメルカプタンなどの揮発性硫黄化合物が口臭の原因である（特許公開平０７−０５５８９５）ことは知られており、口臭抑制の目的のためには、例えばミント、メントール、エッセンシャルオイル、植物エキス等が用いられ、マスキング効果、またはバクテリアに作用している。しかし、これらのものでは、短時間の間では口中をさわやかにし、臭いも少ないが、上記常在菌の持続性口臭抑制が完全でない。
【０００３】
歯の洗浄、清浄には例えば、界面活性剤、研磨剤、粘結剤等の働きで歯の表面はきれいになるが、歯垢が完全に取り除かれず、または、付着防止効果が不足している。ウンデシレン酸、及びその塩（亜鉛、マグネシウム、鉛）等の消臭効果は知られており、固型石鹸、洗顔料、ボディーシャンプー、靴下、靴の中の消臭、体臭防止等に用いられているが、口臭抑制歯磨には用いられていない。本発明の発明者は、鋭意研究の結果ウンデシレン酸エステルが持続性口臭抑制効果と清浄効果があることを見出し、本発明にいたった。
【０００４】
【発明が解決しようとする課題】本発明は、上記の従来技術の問題点を解決できる口臭抑制口腔衛生品組成物を提供することにある。
【０００５】
【課題を解決するための手段】本発明の発明者は、上記課題を解決するためにウンデシレン酸エステルを配合する口臭抑制口腔衛生品組成物を提供するものである。
【０００６】
【発明の実施の形態】朝の起床時に口臭が臭う人は就寝中に口内の雑菌が歯間に残った食べカスを栄養源にして繁殖する際、分解されたものが口臭となり臭うケースも多い。このケースでは、口内の雑菌が原因となっている。口内には食べ物や環境から来る種々の菌が取り込まれ、唾液も多少の静菌効果があるが、フランギルス菌（嫌気性グラム陰性菌）、カビ等の糸状菌（真菌類）を静菌する効果は極めて薄いために他の天然薬剤の力が必要になる。タバコのヤニは、歯垢と共に歯に密着し除去が大変困難である。その結果歯は茶色っぽくなり、きれいなつやが失われる。これらの多くの問題点を一度に解決するのにウンデシレン酸の誘導体に着目し、鋭意研究を行なった。
【０００７】
このような問題を解決するために本発明に使用するウンデシレン酸エステルはウンデシレン酸とアルコールとのエステル化反応によって得られる。エステル化に用いられるアルコール部は飽和、不飽和、環状、直鎖、分岐鎖等各種の組み合わせがあるが、製品化のための配合のし易さ、安定性、効果、発泡を阻害しない、苦くない、飲み込んでも安全等のことからソルビット、グリセリン、ポリグリセリン、エチレングリコール、プロピレングリコール、１，３ブチレングリコール、ジプロピレングリコール、ポリエチレングリコール（２００、４００、６００、１０００、１５００）、キシリット、マルチット、ラクチット、ラクトース、ショ糖、ウンデシレン酸ポリオキシエチレエン（０．１〜１５０モル）ソルビタン、等のアルコール類が好ましい。更には、口腔製品に適している原料としてグリセリン、ソルビット、ショ糖、ポリグリセリン、ポリオキシエチレエンソルビタン等のエステルが好ましい。
【０００８】
ウンデシレン酸エステルの使用量は０．００１以下では効果が期待できず、５．０％以上では、安定なエマルジョンができず、また菌の増殖抑制効果がプラトーに達する。効果の高いウンデシレン酸エステルのモノエステルは苦味があり使用量は０．００１〜３．０％が好ましい。
【０００９】
本発明の口臭抑制歯磨組成物は、練歯磨、粉歯磨、マウスウオッシュなどの通常の剤形とすることができ、これらの剤形に通常用いられる基剤、例えば界面活性剤、研磨剤、粘結剤、甘味剤等を配合し、これに有効成分であるウンデシレン酸エステルが配合される。さらに、本発明の組成物には一般的に配合されている他の薬効成分を配合してもよく、さらに防腐剤、着色料、香料なども配合してもよい。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oral hygiene product for the purpose of suppressing bad breath, and more particularly to a persistent oral odor suppressing composition using undecylenic ester.
[0002]
[Prior art]
According to the prior art, bad breath control dentifrices include preventing tooth decay, whitening teeth, removing plaque, purifying the mouth, preventing bad breath, removing tooth tarnish, and preventing tartar deposition. Some are sought alone, some have only a tooth cleaning effect, and some have both effects. Volatile sulfur compounds such as hydrogen sulfide and methyl mercaptan produced by gram-negative anaerobic bacterium Fusobacterium nieuculataim and Bacteroides gingivalis present in the oral cavity cause bad breath (Patent Publication No. 07-055895). It is known that, for the purpose of suppressing bad breath, for example, mint, menthol, essential oils, plant extracts and the like are used and act on the masking effect or bacteria. However, in these products, the mouth is refreshed and the odor is small for a short time, but the persistent bad odor of the above-mentioned resident bacteria is not perfect.
[0003]
For cleaning and cleaning teeth, for example, the surface of the teeth is cleaned by the action of a surfactant, an abrasive, a binder, or the like, but the plaque is not completely removed or the effect of preventing adhesion is insufficient. The deodorizing effect of undecylenic acid and its salts (zinc, magnesium, lead) and the like is known, and is used for deodorizing solid soap, face wash, body shampoo, socks, shoes, and preventing body odor. It is not used for bad breath control dentifrice. The inventor of the present invention has assiduously studied and found that undecylenic acid ester has a persistent bad breath suppressing effect and a cleansing effect, and has reached the present invention.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a composition for suppressing oral malodor which is capable of solving the above-mentioned problems of the prior art.
[0005]
Means for Solving the Problems The present inventor has provided an oral odor suppressing oral hygiene composition containing undecylenic ester to solve the above-mentioned problems.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION People who smell bad breath when getting up in the morning often break down into bad breath when germs in the mouth breed using food debris remaining between teeth as a nutrient source while sleeping. . In this case, it is caused by bacteria in the mouth. Various bacteria from food and environment are taken into the mouth, and saliva also has some bacteriostatic effect, but the effect of bacteriostatic fungi (fungi) such as fungi (anaerobic gram-negative bacteria) and mold. Is extremely thin and requires the power of other natural agents. Tobacco tarnish adheres to the teeth together with the plaque and is very difficult to remove. The result is a brownish tooth and a loss of clean luster. In order to solve many of these problems at once, we focused on derivatives of undecylenic acid and made intensive studies.
[0007]
In order to solve such a problem, the undecylenic ester used in the present invention is obtained by an esterification reaction between undecylenic acid and an alcohol. The alcohol part used for the esterification has various combinations such as saturated, unsaturated, cyclic, linear, and branched chains. Not available, sorbitol, glycerin, polyglycerin, ethylene glycol, propylene glycol, 1,3-butylene glycol, dipropylene glycol, polyethylene glycol (200, 400, 600, 1000, 1500), xylit, malt Alcohols such as lactit, lactose, sucrose, polyoxyethylene undecylenate (0.1 to 150 mol) sorbitan, and the like are preferable. Further, as raw materials suitable for oral products, esters such as glycerin, sorbitol, sucrose, polyglycerin, and polyoxyethylene sorbitan are preferable.
[0008]
If the amount of undecylenic ester used is 0.001 or less, no effect can be expected, and if it is 5.0% or more, a stable emulsion cannot be obtained, and the effect of inhibiting the growth of bacteria reaches a plateau. The monoester of undecylenic ester having a high effect has a bitter taste, and its use amount is preferably 0.001 to 3.0%.
[0009]
The bad breath suppressing dentifrice composition of the present invention can be made into conventional dosage forms such as toothpaste, powdered toothpaste, mouthwash, etc., and bases usually used in these dosage forms, for example, surfactants, abrasives, A binder, a sweetener and the like are blended, and an undecylenic acid ester as an active ingredient is blended therein. Further, the composition of the present invention may contain other commonly used medicinal ingredients, and may further contain a preservative, a coloring agent, a fragrance and the like.
[0010]
Table 1 shows the antibacterial activity test results of undecylenic acid monoglyceride, which is a typical undecylenic ester. A typical sample undecylenic ester used in the present invention is synthesized by a general ordinary method.
(Test method)
A potato dextrose agar medium to which 3% of 2% undecylenic acid monoglyceride dipropylene glycol solution was added was prepared. A blank medium was similarly prepared. 0.2 ml of a physiological saline solution in which black Aspergillus was dispersed was similarly propagated in this medium, and cultured at 30 ° C.
[Table-1]
EXAMPLES The effect of the present invention for suppressing bad breath will be described in more detail with reference to Examples and Comparative Examples in Table 2, but is not limited thereto.
[Table-2]
A toothpaste test was performed by 25 volunteers using the toothpastes obtained in Comparative Examples and Examples, and evaluation after use was performed. The results are shown in Tables 3 to 6.
(Evaluation method)
Twenty subjects were divided into four groups of five, and each of the comparative examples was brushed once a day in the usual manner each morning, and evaluated 10 days later. Thereafter, each test sample is brushed once every morning, and evaluated 10 days later. Bad breath, plaque and gloss of the teeth were recorded in advance by the judge.
