Description

【0001】
【発明の属する技術分野】
本発明は、保形性に優れ、保存安定性も良好な、水分量が5重量%以下のゲル状口腔用組成物に関する。
【0002】
【従来の技術】
水分量の少ないゲル状口腔用組成物としては、グリセリン等の多価アルコールに酸化エチレン付加モル数2.8以上のハイドロキシエチルセルロースを溶解させた口腔用組成物(特開昭56-95937号)や、グリセリン及び/又はエチレングリコールと水酸基を有する水溶性高分子化合物とカルシウム塩及び/又はバリウム塩を含有する口腔用非水系ペースト状組成物(特開平6-287133号)等が知られている。
しかし、これらの組成物は、十分な保形性が得られず、使用しずらいという問題があり、保存安定性の点でも満足できるものではなかった。
【0003】
一方、カラギーナンは、水溶液中で熱可逆的なゾル−ゲル転移をするため、ゲル化剤等に利用されている。種々の構造のカラギーナンのうち、一般に水溶液中において、ι−カラギーナンはκ−カラギーナンよりも柔らかいゲルを形成するが、シェアによる粘度低下は少なく、λ−カラギーナンはゲル状構造を作らないという特徴が知られている。しかし、グリセリン等の多価アルコールに溶解させた場合は挙動が異なり、いずれのタイプのカラギーナンもそのまま加温溶解後に冷却しただけではゲル化しない。
また、高分子量のポリエチレングリコールや、カルナウバロウ等のワックスもゲル状構造を形成するが、これらだけでゲル化させた場合には、高温保存時や低温から高温までの温度変化保存時の安定性が悪く、分離しやすいという問題がある。
【0004】
【発明が解決しようとする課題】
本発明の目的は、水分量が少なくても、保形性に優れ、保存安定性も良好な口腔用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】
本発明者らは、特定の多価アルコールに、特定のカラギーナン及びアルキル硫酸ナトリウムを組合わせて用いれば、水分量が少なくてもゲル状構造が形成し、保形性及び保存安定性に優れた口腔用組成物が得られることを見出した。
【0006】
すなわち、本発明は、(a)グリセリン、エチレングリコール、ジエチレングリコール及びプロピレングリコールから選ばれる多価アルコール30〜99重量%、(b)ι−カラギーナン又はλ−カラギーナン、並びに(c)アルキル硫酸ナトリウムを含有し、水分量が重量%以下であるゲル状口腔用組成物を提供するものである。
【0007】
【発明の実施の形態】
本発明で用いる成分(a)の多価アルコールとしては、グリセリン、エチレングリコール、ジエチレングリコール及びプロピレングリコールから1種以上が選ばれ、特にグリセリンが、成分(b)のカラギーナンが溶解し易いため好ましい。
成分(a)は、全組成中に10〜99重量%、特に20〜90重量%、更に30〜80重量%配合するのが好ましい。
【0008】
成分(b)のカラギーナンは、ι−カラギーナン又はλ−カラギーナンで、これらを併用することもできる。カラギーナンとしては、例えばMRCポリサッカライド社や、FMC社製の市販品を好適に使用でき、更に、特開平1-129001号に
記載の変性イオタカラギーナン等も使用できる。
カラギーナンは、全組成中に0.001〜5重量%、特に0.01〜2重量%、更に0.05〜1重量%配合するのが、適度な固さのゲル状構造を形成するので好ましい。
また、成分(a)と成分(b)の重量比は、1000:1〜10:1、特に500:1〜50:1であるのが好ましい。
【0009】
成分(c)のアルキル硫酸ナトリウムとしては、炭素数10〜16のアルキル基を有するものが好ましく、特にラウリル硫酸ナトリウム、ミリスチル硫酸ナトリウムが好ましい。
本発明の口腔用組成物は水分量が5重量%以下であるため、水溶性のアルキル硫酸ナトリウムは溶け残ることがある。使用時にすぐに発泡させるためには、粒径の小さいものを用いるのが好ましく、平均粒径100μm以下、特に50μm以下のものが好ましい。
【0010】
アルキル硫酸ナトリウムは、全組成中に0.1〜5重量%、特に0.5〜2重量%配合するのが、適度な固さのゲル状構造を形成するのに寄与するとともに、口腔用組成物に発泡性も付与するので好ましい。
また、成分(b)と成分(c)の重量比は、10:1〜1:100、特に5:1〜1:50であるのが好ましい。
【0011】
本発明の口腔用組成物には、更にキサンタンガムを配合することができ、保存安定性をより高めるので好ましい。キサンタンガムは、全組成中に0.001〜5重量%、特に0.02〜2重量%、更に0.05〜1重量%配合するのが好ましい。
また、キサンタンガムは使用時の泡もちを良くして泡質をクリーミーにする作用も有するが、本発明の口腔用組成物は水分量が5重量%以下であるため、水溶性のキサンタンガムは溶け残ることがある。使用時にすぐに前記作用を発揮させるためには、粒径の小さいものを用いるのが好ましく、平均粒径100μm以下、特に50μm以下のものが好ましい。
【0012】
本発明の口腔用組成物には、発熱体を配合して温熱効果を得ることもできる。発熱体としては、口腔内での水和反応によって発熱する発熱物質が挙げられる。発熱体は、発生温度が38〜50℃、特に40〜45℃となるように用いるのが好ましく、具体的には、無水ゼオライト、無水硫酸マグネシウム、メタリン酸ナトリウム、塩化カルシウム、デキストリン等が挙げられる。
発熱体は、1種以上を用いることができ、全組成中に0〜50重量%、特に20〜30重量%配合するのが好ましい。
【0013】
本発明の口腔用組成物には、更に口腔用組成物に通常用いられる成分、例えば他の界面活性剤、他の増粘剤、研磨剤、薬効剤、甘味料、香料、保存剤、美白剤、湿潤剤、粘結剤等を、適宜配合できる。
【0014】
本発明の口腔用組成物は、水分含量が5重量%以下、好ましくは3重量%以下である。
【0015】
本発明の口腔用組成物は、成分(a)に成分(b)及び(c)を60〜120℃で加温溶解させた後、冷却することにより製造され、ゲル状の組成物が得られる。加熱溶解の際には、成分(b)と成分(c)を別々に成分(a)に溶解してから混合しても良い。冷却する際にゾル−ゲル転移が起こり、ゲル状構造が形成される。ゾル−ゲル転移温度は20〜60℃、特に30〜50℃であるのが、製造上好ましい。また、ゲル−ゾル転移温度が30〜80℃、特に40〜70℃であれば、通常の室温でゾル化したり、粘度物性が顕著に変化することがないので好ましい。これらの転移温度は、カラギーナンのグレード等により調整することができる。なお、ゾル−ゲル転移温度やゲル−ゾル転移温度は、正確には小角X線散乱法などで測定することができるが、それらの温度における性状(流動性の有無)からもおおよその転移温度がわかる。
なお、本発明において、ゲル状とは、見かけ上は流動性がない固体のような性状をいう。
【0016】
【発明の効果】
本発明の口腔用組成物は、保形性に優れ、保存安定性も良好である。

BACKGROUND OF THE INVENTION
The present invention relates to a gel-like composition for oral cavity having excellent shape retention and good storage stability and having a water content of 5% by weight or less.
[0002]
[Prior art]
Examples of gel-like oral compositions having a low water content include oral compositions prepared by dissolving hydroxyethyl cellulose having an ethylene oxide addition mole number of 2.8 or more in a polyhydric alcohol such as glycerin (Japanese Patent Laid-Open No. 56-95937), In addition, a non-aqueous oral paste composition (JP-A-6-287133) containing glycerin and / or ethylene glycol and a water-soluble polymer compound having a hydroxyl group and a calcium salt and / or a barium salt is known.
However, these compositions have a problem that sufficient shape retention cannot be obtained and are difficult to use, and are not satisfactory in terms of storage stability.
[0003]
On the other hand, carrageenan is used as a gelling agent and the like because it undergoes a thermoreversible sol-gel transition in an aqueous solution. Among the carrageenans of various structures, ι-carrageenan generally forms a softer gel than κ-carrageenan in aqueous solution, but there is little decrease in viscosity due to shear, and λ-carrageenan is characterized by not forming a gel-like structure. It has been. However, when it is dissolved in a polyhydric alcohol such as glycerin, the behavior is different, and any type of carrageenan does not gel when it is simply cooled after being heated and dissolved.
High molecular weight polyethylene glycols and waxes such as carnauba wax also form a gel-like structure, but when gelled with these alone, stability during storage at high temperatures or during temperature changes from low to high temperatures is maintained. It is bad and easy to separate.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide an oral composition having excellent shape retention and good storage stability even when the amount of water is small.
[0005]
[Means for Solving the Problems]
When the present inventors use a specific polyhydric alcohol in combination with a specific carrageenan and sodium alkyl sulfate, a gel-like structure is formed even if the amount of water is small, and the shape retention and storage stability are excellent. It has been found that an oral composition can be obtained.
[0006]
That is, the present invention contains (a) 30 to 99% by weight of a polyhydric alcohol selected from glycerin, ethylene glycol, diethylene glycol and propylene glycol, (b) ι-carrageenan or λ-carrageenan, and (c) sodium alkyl sulfate. In addition, the present invention provides a gel oral composition having a water content of 3 % by weight or less.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
As the polyhydric alcohol of component (a) used in the present invention, at least one selected from glycerin, ethylene glycol, diethylene glycol and propylene glycol is selected, and glycerin is particularly preferable because the carrageenan of component (b) is easily dissolved.
Component (a) is preferably blended in the total composition in an amount of 10 to 99% by weight, particularly 20 to 90% by weight, and more preferably 30 to 80% by weight.
[0008]
The carrageenan of component (b) is ι-carrageenan or λ-carrageenan, which can be used in combination. As the carrageenan, for example, commercially available products manufactured by MRC polysaccharides and FMC can be suitably used, and modified iota carrageenan described in JP-A-1-129001 can also be used.
Carrageenan is preferably blended in the total composition in an amount of 0.001 to 5% by weight, particularly 0.01 to 2% by weight, more preferably 0.05 to 1% by weight, because it forms a gel-like structure with an appropriate hardness. .
The weight ratio of component (a) to component (b) is preferably 1000: 1 to 10: 1, particularly 500: 1 to 50: 1.
[0009]
As the component (c) sodium alkyl sulfate, those having an alkyl group having 10 to 16 carbon atoms are preferable, and sodium lauryl sulfate and sodium myristyl sulfate are particularly preferable.
Since the oral cavity composition of the present invention has a water content of 5% by weight or less, the water-soluble sodium alkyl sulfate may remain undissolved. In order to foam immediately during use, it is preferable to use one having a small particle diameter, and an average particle diameter of 100 μm or less, particularly 50 μm or less is preferable.
[0010]
Sodium alkyl sulfate is added to the total composition in an amount of 0.1 to 5% by weight, particularly 0.5 to 2% by weight, which contributes to the formation of a gel-like structure with an appropriate hardness and is a composition for the oral cavity. Since foaming property is also given to a thing, it is preferable.
The weight ratio of component (b) to component (c) is preferably 10: 1 to 1: 100, particularly 5: 1 to 1:50.
[0011]
In the composition for oral cavity of the present invention, xanthan gum can be further blended, which is preferable because the storage stability is further improved. Xanthan gum is preferably blended in the total composition in an amount of 0.001 to 5% by weight, particularly 0.02 to 2% by weight, and more preferably 0.05 to 1% by weight.
Xanthan gum also has the effect of improving foaminess during use to make the foam quality creamy. However, since the oral composition of the present invention has a water content of 5% by weight or less, the water-soluble xanthan gum remains undissolved. Sometimes. In order to exert the above-mentioned action immediately at the time of use, it is preferable to use those having a small particle diameter, and those having an average particle diameter of 100 μm or less, particularly 50 μm or less are preferable.
[0012]
The composition for oral cavity of the present invention can be mixed with a heating element to obtain a thermal effect. Examples of the heating element include a pyrogen that generates heat by a hydration reaction in the oral cavity. The heating element is preferably used so that the generation temperature is 38 to 50 ° C., particularly 40 to 45 ° C., and specific examples include anhydrous zeolite, anhydrous magnesium sulfate, sodium metaphosphate, calcium chloride, and dextrin. .
One or more heating elements can be used, and 0 to 50% by weight, particularly 20 to 30% by weight, is preferably blended in the total composition.
[0013]
The oral composition of the present invention further includes components usually used in oral compositions, such as other surfactants, other thickeners, abrasives, medicinal agents, sweeteners, fragrances, preservatives, whitening agents. , A wetting agent, a binder, and the like can be appropriately blended.
[0014]
The oral composition of the present invention has a water content of 5% by weight or less, preferably 3% by weight or less.
[0015]
The composition for oral cavity of the present invention is produced by heating and dissolving the components (b) and (c) in the component (a) at 60 to 120 ° C. and then cooling to obtain a gel-like composition. . At the time of dissolution by heating, the component (b) and the component (c) may be separately dissolved in the component (a) and then mixed. During cooling, a sol-gel transition occurs and a gel-like structure is formed. The sol-gel transition temperature is preferably 20 to 60 ° C., particularly preferably 30 to 50 ° C. in terms of production. A gel-sol transition temperature of 30 to 80 ° C., particularly 40 to 70 ° C., is preferable because it does not form a sol at ordinary room temperature and the viscosity properties do not change significantly. These transition temperatures can be adjusted by the carrageenan grade or the like. The sol-gel transition temperature and the gel-sol transition temperature can be accurately measured by a small-angle X-ray scattering method or the like, but the approximate transition temperature is also determined from the properties at these temperatures (the presence or absence of fluidity). Recognize.
In the present invention, the gel state means a solid state property that does not seem to have fluidity.
[0016]
【The invention's effect】
The composition for oral cavity of this invention is excellent in shape retention property, and its storage stability is also favorable.
[0017]
【Example】
Example 1
The composition for oral cavity of the composition shown in Table 1 was manufactured, and the gel formation state and the storage stability were evaluated. The results are also shown in Table 1.
[0018]
(Manufacturing method)
A container containing a mixed solution of glycerin and propylene glycol was heated to 80 ° C. in a water bath, and other components were added thereto, followed by stirring for 1 hour (adjusted to a total of 1 kg). Thereafter, the container was taken out, cooled to about 50 ° C., transferred to four 150 mL cups, and further cooled to room temperature of 25 ° C. to obtain an oral composition.
[0019]
(Evaluation methods)
(1) Gel formation state:
The gel formation state after storage at 25 ° C. for 12 hours was observed, and “+” indicates that the gel is formed, and “−” indicates that the gel is not formed.
[0020]
(2) Storage stability:
Each cup was stored at 50 ° C. for 1 week and at a cycle of −15 to 60 ° C./day for 1 week, returned to room temperature, and then its properties were evaluated according to the following criteria.
○: No separation.
Δ: Some separation.
×: Clearly separated.
[0021]
[Table 1]
Figure 0003929650
[0022]
From the results shown in Table 1, the products of the present invention all formed a gel-like structure (both sol-gel transition temperatures were in the range of 30 ° C. to 45 ° C.), had excellent shape retention properties, and good storage stability. .
Here, although it is said that λ-carrageenan generally does not form a gel, this system formed a gel (Product 2 of the present invention). Moreover, although it is known that κ-carrageenan forms a hard gel in an aqueous solution system, the gel was not formed because it hardly dissolved in this system (Comparative Product 4).
[0023]
Example 2
A gel oral composition having the composition shown in Table 2 was produced.
[0024]
(Manufacturing method)
A water-soluble polymer such as carrageenan was added to a polyhydric alcohol solution such as glycerin, stirred at 80 ° C. for 1 hour, cooled to about 50 ° C., then other components were added, and deaerated and mixed according to a conventional method. Thereafter, the tube was filled to obtain a gel oral composition.
[0025]
[Table 2]
Figure 0003929650
[0026]
After the obtained composition for oral cavity was stored at 25 ° C. for 1 day, 1 g was placed on a toothbrush and the appearance after 1 minute was evaluated. As a result, the shape did not almost collapse and the shape retention was excellent. Further, when the storage stability was evaluated in the same manner as in Example 1, no separation was observed, and the storage stability was good.
Furthermore, when a comparative product using hydroxyethyl cellulose or hydroxypropyl cellulose instead of carrageenan was manufactured, it was very inconvenient to use because it had poor stringiness when attached to toothbrushes and poor shape retention. .
[0027]
In Examples 1 and 2, carrageenan and sodium alkyl sulfate were both those having an average particle size of 20 μm. All of the compositions for oral cavity of the present invention were excellent in foaming and foam quality at the time of dentifrice despite having a low water content.
