Description

消臭用粉末組成物Deodorant powder composition
　本発明は、散布面への散布性が向上した消臭用粉末組成物に関する。 The present invention relates to a deodorant powder composition having improved sprayability on a spray surface.
　近年、生活臭や体臭への意識の高まりに伴い、消臭を目的とした製品が提供されている。消臭用製品は、通常、液状又は固形（スティック）状の形態で提供されている。また、このような消臭用製品に配合される成分は消臭メカニズムに応じて選択されており、例えば、臭いの原因菌に作用する抗菌成分、臭いの原因を発生する汗を抑制する制汗成分、臭いを吸着する消臭成分等が挙げられる。 In recent years, with the growing awareness of daily life odor and body odor, products aimed at deodorizing have been provided. Deodorant products are usually provided in liquid or solid (stick) form. In addition, the components to be blended in such deodorant products are selected according to the deodorizing mechanism. For example, antibacterial components that act on odor-causing bacteria and antiperspirants that suppress sweat that causes odors. Examples include components and deodorant components that adsorb odors.
　具体的には、抗菌成分としては、ミョウバン（特許文献１）、ウンデシレン酸亜鉛（特許文献２）等が知られており、制汗成分としては、ミョウバンやアルミニウムヒドロキシクロライド等（特許文献３）が知られており、消臭成分としては、シリカゲル、アルミナ、酸化チタン、酸化亜鉛等の金属酸化物（特許文献４）が知られている。 Specifically, alum (Patent Document 1), zinc undecylene (Patent Document 2) and the like are known as antibacterial components, and alum, aluminum hydroxychloride and the like (Patent Document 3) are known as antiperspirant components. As known deodorant components, metal oxides such as silica gel, alumina, titanium oxide, and zinc oxide (Patent Document 4) are known.
　さらに、消臭用製品には、汗などの湿気に対してべたつきを抑制し良好な使用感を付与するために、タルク、シリカ、酸化アルミニウム等の無機粉体が配合される（特許文献５）ことも多い。 Further, the deodorant product contains an inorganic powder such as talc, silica, or aluminum oxide in order to suppress stickiness against moisture such as sweat and give a good feeling of use (Patent Document 5). Often.

　消臭用製品は様々に創出されており、液状又は固形（スティック）状の消臭用製品は飽和状態にある。一方で、消臭志向への意識はますます高まっており、消費者を満足させるための新たな消臭用製品が求められている。そこで本発明者らは、消臭効果をより効果的に得るための製品形態として、有効成分の粒子そのものを直接対象に適用できる粉末状の消臭用組成物に着眼した。 Various deodorant products have been created, and liquid or solid (stick) deodorant products are saturated. On the other hand, awareness of deodorant consciousness is increasing more and more, and new deodorant products for satisfying consumers are required. Therefore, the present inventors have focused on a powdery deodorant composition in which the particles of the active ingredient itself can be directly applied to the target as a product form for obtaining the deodorant effect more effectively.
　ここで、粉末状の消臭用組成物は消臭対象面に対して散布して使用するところ、効率的に消臭効果を得るためには、使用時において、粉末状の当該組成物が散布面の全体に展開し（広がり）且つ散布面に均一に付着している必要がある。そこで、粉末状消臭用組成物の散布面への付着均一性及び展開容易性（広がり易さ）について検討したところ、付着均一性と展開容易性とが両立しない課題に直面した。これは、粉末粒子が面上に広がりやすい性質が本質的に滑りやすい性質であることから面への付着を困難にし、反対に粉末粒子が面へ均一に付着できる性質が本質的に滑りにくい性質であることから面上での広がりを困難にしているためであると考えられる。 Here, the powdery deodorant composition is used by spraying it on the surface to be deodorized. However, in order to efficiently obtain the deodorant effect, the powdery deodorant composition is sprayed at the time of use. It needs to be spread (spread) over the entire surface and evenly adhered to the sprayed surface. Therefore, when the uniformity of adhesion and the ease of deployment (easiness of spreading) of the powdery deodorant composition on the spraying surface were examined, the problem that the uniformity of adhesion and the ease of deployment were incompatible was faced. This is because the property that the powder particles easily spread on the surface is essentially slippery, which makes it difficult to adhere to the surface, and conversely, the property that the powder particles can uniformly adhere to the surface is essentially non-slip. Therefore, it is considered that this is because it is difficult to spread on the surface.
　そこで、本発明は、粉末状でありながら、散布面に対する付着均一性と展開容易性とが両立した（以下において、付着均一性と展開容易性とを総合して「散布性」とも記載する。）消臭用組成物を提供することを目的とする。 Therefore, in the present invention, although it is in the form of powder, both adhesion uniformity and deployability on the spray surface are compatible (hereinafter, the adhesion uniformity and deployability are collectively referred to as "sprayability". ) An object is to provide a deodorant composition.
　本発明者は鋭意検討を行ったところ、平均粒子径が２０μｍ以下のタルク及び／又はミョウバンに、平均粒子径が２０μｍ以下の二酸化ケイ素を１０～４５重量％配合することで、消臭用組成物が粉末でありながら、散布面に対する付着均一性と展開容易性とを両立できることを見出した。本発明は、この知見に基づいて、更に検討を重ねることにより完成したものである。即ち、本発明は、下記に掲げる態様の発明を提供する。 As a result of diligent studies, the present inventor has made a deodorizing composition by blending 10 to 45% by weight of silicon dioxide having an average particle size of 20 μm or less with talc and / or alum having an average particle size of 20 μm or less.

製剤形態
　本発明の消臭用粉末組成物の製剤形態は粉末状である。粉末状であることで、有効成分の粒子そのものを直接対象に適用できる。有効成分を粒子の形態で対象に適用することは、適用された粒子が接触した微細領域において、有効成分が最大限の濃度で適用されることで消臭効果が最大化されるため、液状及び固形状で製剤された消臭用組成物よりも格段に優れている。さらに、本発明の消臭用粉末組成物は付着容易性に優れていることによって対象表面において付着した粒子の均一性に優れているため、有効成分が最大限の濃度で適用される微細領域がそれぞれ対象表面全体にわたってまんべんなく形成される。このため、本発明の消臭用粉末組成物は非常に消臭性に優れる。 Formulation form The formulation form of the deodorant powder composition of the present invention is in the form of powder. By being in powder form, the particles of the active ingredient itself can be directly applied to the target. Applying the active ingredient to the subject in the form of particles is liquid and because the deodorant effect is maximized by applying the active ingredient at the maximum concentration in the microscopic region where the applied particles are in contact. It is significantly superior to the deodorant composition formulated in solid form. Further, since the deodorant powder composition of the present invention is excellent in the ease of adhesion and thus the uniformity of the particles adhering on the target surface, the fine region to which the active ingredient is applied at the maximum concentration is formed. Each is formed evenly over the entire surface of the object. Therefore, the deodorant powder composition of the present invention is extremely excellent in deodorant properties.
　また、本発明の消臭用粉末組成物は、皮膚に直接適用する外用剤、及び皮膚に直接適用しない非外用剤のいずれの製剤形態であってもよい。また、外用剤である場合は、皮膚外用医薬品、医薬部外品、化粧料のいずれの製剤形態であってもよい。本発明の消臭用粉末組成物は散布性に優れているため、本来的に対象に対する散布が難しい非外用剤として用いられる場合に特に有用である。 Further, the deodorant powder composition of the present invention may be in any form of an external preparation that is directly applied to the skin and a non-external preparation that is not directly applied to the skin. In addition, when it is an external preparation, it may be in any of a skin external medicine, a quasi-drug, and a cosmetic. Since the deodorant powder composition of the present invention is excellent in sprayability, it is particularly useful when it is used as a non-external agent which is inherently difficult to spray on a subject.
使用方法
　本発明の消臭用粉末組成物は、消臭（デオドラント）用品として用いることができる。本発明の消臭用粉末組成物が外用剤である場合は、通常の外用剤（パウダー剤）の使用方法と同様に、皮膚へ直接塗布又は散布することに使用することができる。さらに、本発明の消臭用粉末組成物が非外用剤である場合は、抗菌対象へ直接散布することにより使用することができる。抗菌対象としては、皮膚と直接的又は間接的に接触することで汗や雑菌が付きやすい物品が挙げられ、より好ましくは履物（靴、スリッパ、サンダル）の内側、フットウェア（靴下、ストッキング）、及び敷物（絨毯、カーペット、クッションフロア、フローリング）の表面が挙げられ、さらに好ましくは、高温多湿で汗や雑菌との接触機会が多い、履物の内側及び靴下が挙げられ、一層好ましくは、洗う機会が無い又は少ない履物の内側が挙げられる。履物の中でも、足の甲及びかかとを覆うことで、より高温多湿で汗や雑菌との接触機会がより多く、且つその構造上、内部に粉末組成物を散布することが本来的に困難である、靴が特に好ましい。 Method of Use The deodorant powder composition of the present invention can be used as a deodorant (deodorant) product. When the deodorant powder composition of the present invention is an external preparation, it can be used for direct application or spraying on the skin in the same manner as in the usual method of using the external preparation (powder preparation). Furthermore, when the deodorant powder composition of the present invention is a non-external preparation, it can be used by directly spraying it on an antibacterial object. Antibacterial targets include articles that are prone to sweat and germs due to direct or indirect contact with the skin, more preferably inside footwear (shoes, slippers, sandals), footwear (socks, stockings), etc. And the surface of rugs (carpets, carpets, cushion floors, flooring), more preferably the inside of footwear and socks, which are hot and humid and have a lot of contact with sweat and germs, more preferably the opportunity to wash. The inside of footwear with no or few is mentioned. Even in footwear, by covering the instep and heel, there are more opportunities for contact with sweat and germs due to higher temperature and humidity, and due to its structure, it is inherently difficult to spray the powder composition inside. , Shoes are especially preferred.
　以下に実施例を示して本発明をより具体的に説明するが、本発明はこれらに限定されるものではない。 The present invention will be described in more detail with reference to Examples below, but the present invention is not limited thereto.
試験例
　縦９ｃｍ×横１３ｃｍの角型シャーレの底面一面に、履物の中敷きに用いられる、シボ加工がされていない合成皮革（黒色、ポリウレタン製）を貼付した。また、表２～表４に示す組成の消臭用粉末組成物を調製した。消臭用粉末組成物の調製に用いた成分のうち、アルミニウムヒドロキシクロライドはＡｌ2（ＯＨ）5Ｃｌを用い、ミョウバンとしては焼きカリウムミョウバン（乾燥カリウムミョウバン）を用いた。消臭用粉末組成物約０．２５ｃｍ3を、合成皮革の中心（１ｃｍ×１ｃｍ）に静置した。その後、シャーレを振動器（ＡＬＭＩＧＨＴＹ　ＳＨＡＫＥＲ　ＡＳ－１）に設置し、縦方向に１０秒間（振幅４ｃｍ、２５０往復／分）、その後横方向に１０秒間（縦方向と同条件）振動させた。合成皮革の上で広がった消臭用粉末組成物について、以下の方法で付着均一性及び展開容易性を評価した。 The bottom one surface of the square dish Experiment vertical 9cm × horizontal 13cm, used in insole of footwear was affixed synthetic leather not been embossed (black, polyurethane). In addition, deodorant powder compositions having the compositions shown in Tables 2 to 4 were prepared. Among the components used in the preparation of the deodorant powder composition, Al 2 (OH) 5 Cl was used as the aluminum hydroxychloride, and baked potassium alum (dried potassium alum) was used as the alum. About 0.25 cm 3 of the deodorant powder composition was allowed to stand in the center of the synthetic leather (1 cm × 1 cm). Then, the petri dish was installed in a vibrator (ALMIGHTY SHAKER AS-1) and vibrated in the vertical direction for 10 seconds (amplitude 4 cm, 250 reciprocations / minute) and then in the horizontal direction for 10 seconds (same conditions as in the vertical direction). The deodorant powder composition spread on synthetic leather was evaluated for adhesion uniformity and ease of deployment by the following methods.
（付着均一性の評価）
　消臭用粉末組成物の合成皮革上での付着状態を、以下の基準に基づいて分類し、付着均一性を評価した。結果を表２～４に示す。
　　　○：粉末状組成物が移動した跡が一様に白くなっている
　　　△：粉末状組成物が移動した跡が線状に白くなっている
　　　×：粉末状組成物が移動した跡が点状に白くなっている
　なお、代表例として、比較例６（×評価）、比較例２（△評価）、及び比較例４（○評価）を挙げ、付着均一性の評価基準を表す具体的な付着状態の態様を表１に示す。 (Evaluation of adhesion uniformity)
The adhesion state of the deodorant powder composition on synthetic leather was classified based on the following criteria, and the adhesion uniformity was evaluated. The results are shown in Tables 2-4.

（展開容易性の評価）
　消臭用粉末組成物の縦方向の最大展開距離及び横方向の最大展開距離を測定し、それら最大展開距離を積算することによって、展開容易性の指標とした。展開容易性の指標が大きい程、展開性が優れていると判断できる。この展開容易性の指標を以下の基準に基づいて分類し、展開容易性を評価した。なお、履物の内部に散布する場合のように比較的狭い領域への散布において必要十分な展開容易性のレベルは、＋＋である。結果を表２～４に示す。
　　　＋＋＋＋　　９７以上
　　　　＋＋＋　　８７以上９７未満
　　　　　＋＋　　７７以上８７未満
　　　　　　＋　　６７以上７７未満
　　　　　　－　　５７以上６７未満
　　　　　－－　　５７未満 (Evaluation of ease of deployment)
The maximum deployment distance in the vertical direction and the maximum deployment distance in the horizontal direction of the deodorant powder composition were measured, and the maximum deployment distances were integrated to obtain an index of ease of deployment. It can be judged that the larger the index of the ease of deployment, the better the expandability. This index of ease of deployment was classified based on the following criteria, and the ease of deployment was evaluated. The level of ease of deployment necessary and sufficient for spraying in a relatively narrow area, such as when spraying inside footwear, is ++. The results are shown in Tables 2-4.
++++ 97 or more +++ 87 or more and less than 97 ++ 77 or more and less than 87 + 67 or more and less than 77-57 or more and less than 67 --- less than 57

　比較例１～比較例３に示されるとおり、二酸化ケイ素は平均粒子径の違いにより付着均一性及び展開容易性の程度が推移する傾向がみられるものの、それらを両立させることは出来なかった。また比較例４及び比較例５に示されるとおり、タルク及びミョウバンは付着均一性に優れているが、展開容易性に問題があった。反対に、比較例６に示されるとおり、アルミニウムヒドロキシクロライドは展開容易性に極めて優れているが、付着均一性に問題があった。更に、比較例７に示されるとおり、付着均一性に優れたタルク及びミョウバンと、展開容易性に優れたアルミニウムヒドロキシクロライドを組み合わせても、両特性は両立できず、展開容易性が極端に悪化する結果となった。 As shown in Comparative Examples 1 to 3, silicon dioxide tended to change the degree of adhesion uniformity and deployability due to the difference in average particle size, but it was not possible to achieve both. Further, as shown in Comparative Example 4 and Comparative Example 5, talc and alum are excellent in adhesion uniformity, but there is a problem in ease of deployment. On the contrary, as shown in Comparative Example 6, aluminum hydroxychloride is extremely excellent in deployability, but has a problem in adhesion uniformity. Further, as shown in Comparative Example 7, even if talc and alum having excellent adhesion uniformity and aluminum hydroxychloride having excellent deployability are combined, both characteristics cannot be compatible and the deployability is extremely deteriorated. The result was.
　これに対し、実施例１～実施例７に示されるとおり、付着均一性に優れたタルク及びミョウバンに、１０～４５重量％の二酸化ケイ素を組み合わせると、優れた付着均一性を奏するとともに、展開容易性が顕著に向上した。つまり、実施例１～７によって、優れた散布性が得られた。一方、比較例８～１０に示されるとおり、二酸化ケイ素の含有量が４５重量％を超えると、付着均一性に問題が生じた。


  On the other hand, as shown in Examples 1 to 7, when 10 to 45% by weight of silicon dioxide is combined with talc and alum having excellent adhesion uniformity, excellent adhesion uniformity is obtained and deployment is easy. The sex was significantly improved. That is, excellent dispersibility was obtained in Examples 1 to 7. On the other hand, as shown in Comparative Examples 8 to 10, when the content of silicon dioxide exceeds 45% by weight, a problem arises in adhesion uniformity.
