Abstract
Description
【０００１】
【発明の属する技術分野】
この発明は、高い光輝感を呈する顔料を含有し、優れた意匠性を有するゲル状組成物に関する。さらには、このゲル状組成物の優れた意匠性を利用した種々の製品に関する。
【０００２】
【従来の技術】
ゲル状組成物は、その内部に多量の水分を保持したり、その内部および表面の空隙中に化学物質を吸着したりする機能を備える。これらの機能を利用して、従来から芳香剤、消臭剤、殺虫剤、保冷材または頭髪用化粧料などに利用されている。
【０００３】
これらのゲル状組成物は、利用形態・利用態様が比較的人目に付き易いことから、それ自体の意匠性を高める工夫が従来から施されている。たとえば、寒天やゼラチンなどのマトリックスゲルの中にパールマイカやアルミニウム粉体などの光沢顔料を配合したものが上市されている。
【０００４】
【発明が解決しようとする課題】
しかし、パールマイカは可視光反射率が低いため、マトリックスゲルに配合した場合、その個々の粒子の視認性が低く、ゲル状組成物の輪郭・陰影がハッキリしないものになってしまう。また、アルミニウム粉末などの金属粉体を配合した場合は、反射光が散乱してしまうため、ゲル状組成物に異物感が生じてしまったり、その奥行き感が低下してしまったりする。
【０００５】
この発明は、このような問題点に着目してなされたものである。その目的とするところは、ゲル状組成物に高い光輝感を付与し、その意匠性を高めることにある。さらには、ゲル状組成物の高い意匠性を利用した各種製品を提供することにある。
【０００６】
【課題を解決するための手段】
上記の課題を解決するために、この発明は、ガラス粉体を二酸化チタンの薄膜で被覆した光輝性顔料をマトリックスゲルに配合することを特徴とする。ガラス粉体は、透明性が高く、かつ、その表面が平滑であることから、乱反射を生じ難く、ゲル状組成物に異物感を与え難い。さらに、ガラス粉体が二酸化チタンの薄膜で被覆されることにより、それらの屈折率の違いから光輝性顔料の可視光反射率が向上する。これにより、マトリックスゲル中における光輝性顔料の視認性が向上し、ゲル状組成物の意匠性も向上する。
【０００７】
このゲル状組成物を従来の各種用途で利用することにより、それら製品の意匠性を高めることができる。
【０００８】
【発明の実施の形態】
以下、この発明の実施の形態について、詳細に説明する。なお、以下の実施の形態に限定する趣旨ではない。
【０００９】
光輝性顔料は、ガラス粉体の表面を二酸化チタンの薄膜で被覆したものである。このガラス粉体は、その形状をとくに限定されるものではなく、球状、針状または鱗片状などが例示される。ガラス粉体は、透明性が高く、マイカまたはアルミニウム粉体などのように遮光性を有しないため、マトリックスゲルに配合された場合でも、ゲル状組成物に異物感を与えることがない。さらには、可視光透過率８０％以上のガラス粉体が好ましい。
【００１０】
また、これらの中でも、鱗片状ガラスがとくに好ましい。鱗片状ガラスは、他の形状に比べ、比表面積と平滑面が格段に大きく、その反射光に指向性があるため、光輝性顔料がマトリックスゲルに包含されても、その視認性が低下し難い。そのため、鱗片状ガラスからなる光輝性顔料は、ゲル状組成物の意匠性を高めることに適している。
【００１１】
鱗片状ガラスの大きさは、とくに限定されるものではないが、マトリックスゲル中で均一分散でき、かつ、肉眼で異物と見なされない程度の大きさが好ましい。具体的には、平均厚さ１〜５μｍ、平均粒径１０〜５００μｍ、アスペクト比１０〜１００のものが好適である。
【００１２】
ガラス粉体の屈折率は、その組成成分含有率により多少幅があるが、およそ１．４〜１．６である。これに対し、二酸化チタンの屈折率は、アナターゼ型が２．５前後で、ルチル型が２．７前後である。一般に、屈折率が変化する界面では反射が生じ易いことから、この光輝性顔料は、ガラス粉体と二酸化チタンの薄膜との界面において、またこの薄膜とマトリックスゲルとの界面において反射が生じ易い。したがって、この光輝性顔料であれば、従来用いられていたパールマイカよりも強い反射光が得られる。
【００１３】
二酸化チタンの屈折率が高いほど、光輝性顔料の反射光は強くなるので、二酸化チタンはルチル型であることが好ましい。また、ルチル型は、アナターゼ型よりも化学的に安定で、光触媒活性も低いことから、ルチル型の薄膜であれば、光輝性顔料が性能劣化し難く、接触するマトリックスゲルを変質させることもない。
【００１４】
二酸化チタンの薄膜の光学厚さが可視光波長の四分の一の整数倍のとき、光輝性顔料は干渉色を呈する。これは干渉色の文字通り、二酸化チタンの薄膜の表面で反射した特定波長の光と、この薄膜とガラス粉体との界面で反射した同波長の光とが強め合い、また打ち消し合うからである。したがって、二酸化チタンの薄膜の厚さを調整することにより、所望の干渉色が得られる。また、二酸化チタンの薄膜の厚さは、１〜２００μｍが好ましい。この厚さが１μｍ未満では、反射が生じ難く、一方２００μｍを越えると、二酸化チタンの結晶成長に基づく薄膜表面の凹凸が無視できなくなり、反射光の散乱が問題となる。
【００１５】
鱗片状ガラスの表面を二酸化チタンの薄膜で被覆した光輝性顔料として、たとえば日本板硝子社製のメタシャイン（登録商標）ＲＣシリーズ（ＭＣ５０９０ＲＳ，ＭＣ５０９０ＲＹ，ＭＣ５０９０ＲＲ，ＭＣ５０９０ＲＢ，ＭＣ５０９０ＲＧ，ＭＣ１０８０ＲＳ，ＭＣ１０８０ＲＹ，ＭＣ１０８０ＲＲ，ＭＣ１０８０ＲＢ，ＭＣ１０８０ＲＧ，ＭＣ１０４０ＲＳ，ＭＣ１０４０ＲＹ，ＭＣ１０４０ＲＲ，ＭＣ１０４０ＲＢ，ＭＣ１０４０ＲＧ，ＭＣ１０２０ＲＳ，ＭＣ１０２０ＲＹ，ＭＣ１０２０ＲＲ，ＭＣ１０２０ＲＢ，ＭＣ１０２０ＲＧ）が挙げられる。
【００１６】
マトリックスゲルとしては、その種類をとくに限定されるものではなく、たとえばカルボキシビニルポリマー、ヒドロキシエチルセルロース、ポリビニルピロリドン、キトサンないしポリアクリル酸塩類などの有機高分子からなるゲル形成剤と、ポリオキシエチレンポリオキシプロピレンセチルエーテルリン酸、ポリオキシエチレンポリオキシプロピレングリコール、デキストリン脂肪酸エステルないしステアリン酸ナトリウムなどのゲル化剤とを混合し反応させたものが挙げられる。また、カラギーナン、アルギン酸ソーダ、ジュランガム、寒天、ゼラチン、キトサンなどの天然高分子化合物もゲル形成剤として使用される。なお、ゲル化剤は、ゲル形成剤の粘度およびゲル状組成物の利用用途に応じて必要な場合のみ使用すればよい。
【００１７】
上記の干渉色を呈する光輝性顔料と併用して、マトリックスゲルに着色剤を添加してもよい。たとえば、光輝性顔料の干渉色と補色にあたる色を呈する着色剤を併用することにより、ゲル状組成物の外観に一層の深みを付与できる。光輝性顔料以外の着色剤としては、たとえば塩基性または酸性の水溶性染料、アゾ系、アントラキノン系またはペリレン系などの油溶性染料、酸化鉄または複合酸化物などの無機顔料、アゾ系、フタロシアニン系、アントラキノン系、インジゴ系、ペリレン系またはキナクリドン系などの有機顔料、硫酸カルシウム系（母体結晶がＣａＳで付活剤がＢｉ）または硫酸亜鉛系（母体結晶がＺｎＳで付活剤がＣｕ）などの蓄光顔料、あるいはＲｈｏｄａｍｉｎｅ Ｂ、Ｒｈｏｄａｍｉｎｅ ６Ｇ、Ｒｈｏｄａｍｉｎｅ Ｓ、Ｅｏｓｉｎｅ、Ｂａｓｉｃ ｙｅｌｌｏｗ ＨＧ、Ｂｒｉｌｌｉａｎｔｓｕｌｆｏｆｌａｖｉｎｅ ＦＦ、ＴｈｉｏｆｌａｖｉｎｅまたはＦｌｕｏｒｅｓｃｅｉｎなどの蛍光色素／顔料などが挙げられる。また、干渉色を呈しない無彩色の光輝性顔料と、有彩色の着色剤とを組み合わせてもよい。
【００１８】
ゲル状組成物中における光輝性顔料の含有率は、０．１〜３０質量％であることが好ましく、さらには０．５〜１０質量％が好適である。この含有率が０．１質量％未満の場合は、ゲル状組成物の光輝感があまり向上しない。一方、３０質量％を超えると、グリッター感が強くなりすぎて、却ってゲル状組成物の意匠性が損なわれる。
【００１９】
光輝性顔料をマトリックスゲル中に配合する手段は、とくに限定されるものではなく、公知の手段をそのまま利用することができる。たとえば、マトリックスゲルの流動性が高い段階（溶媒除去前またはゲル化剤を添加する前など）で光輝性顔料を添加し、それらを均一に混練して、溶媒を除去するなど粘度を上げつつ所望の形状に成型する方法が挙げられる。
【００２０】
このようにして作製したゲル状組成物は、従来からゲル状組成物が利用されている製品にそのまま使用することができる。たとえば、芳香剤、消臭剤、忌避剤、誘引剤、殺虫剤、保冷剤、外用医薬剤、浴用化粧料、蝋製品または保冷材などが挙げられる。なお、蝋製品としては、たとえば水飴のような粘性のある蝋の中にドライフラワーなどを埋設した観賞用キャンドルが挙げられ、浴用化粧料としては、洗顔用の透明石鹸などが例示される。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gel composition containing a pigment exhibiting high glitter and having excellent design properties. Further, the present invention relates to various products utilizing the excellent design property of the gel composition.
[0002]
[Prior art]
The gel-like composition has a function of retaining a large amount of water therein, and a function of adsorbing a chemical substance into the inside and the voids on the surface. Utilizing these functions, it has been conventionally used for fragrances, deodorants, insecticides, cold insulators, hair cosmetics, and the like.
[0003]
Since these gel-like compositions are relatively easy to use in the form of use and manner of use, a device for improving the design of the gel-like composition has been conventionally used. For example, a matrix gel such as agar or gelatin mixed with a luster pigment such as pearl mica or aluminum powder is on the market.
[0004]
[Problems to be solved by the invention]
However, since pearl mica has a low visible light reflectance, when blended in a matrix gel, the visibility of individual particles is low, and the contours and shadows of the gel composition are not clear. Further, when a metal powder such as an aluminum powder is blended, reflected light is scattered, so that a feeling of a foreign substance is generated in the gel composition, or the depth of the gel composition is reduced.
[0005]
The present invention has been made in view of such a problem. The purpose is to impart high glitter to the gel composition and enhance its design. Another object of the present invention is to provide various products utilizing the high design property of the gel composition.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is characterized in that a glitter pigment obtained by coating a glass powder with a thin film of titanium dioxide is blended in a matrix gel. Since glass powder has high transparency and a smooth surface, irregular reflection is unlikely to occur, and it is difficult for the gel composition to give a foreign substance sensation. Further, by covering the glass powder with a thin film of titanium dioxide, the visible light reflectance of the glitter pigment is improved due to the difference in the refractive index between them. Thereby, the visibility of the glitter pigment in the matrix gel is improved, and the design of the gel composition is also improved.
[0007]
By utilizing this gel composition for various conventional uses, the design of those products can be enhanced.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail. In addition, it is not the meaning limited to the following embodiment.
[0009]
The glitter pigment is obtained by coating the surface of a glass powder with a thin film of titanium dioxide. The shape of the glass powder is not particularly limited, and examples thereof include a spherical shape, a needle shape, and a scale shape. Glass powder has high transparency and does not have a light-shielding property like mica or aluminum powder. Therefore, even when mixed with a matrix gel, the gel composition does not give a foreign substance feeling to the gel composition. Further, glass powder having a visible light transmittance of 80% or more is preferable.
[0010]
Among these, flaky glass is particularly preferred. Scaly glass, compared with other shapes, the specific surface area and the smooth surface are significantly larger, and since the reflected light has directivity, even if the brilliant pigment is included in the matrix gel, its visibility is hardly reduced. . Therefore, the glitter pigment made of glass flakes is suitable for enhancing the design of the gel composition.
[0011]
The size of the glass flakes is not particularly limited, but is preferably a size that can be uniformly dispersed in the matrix gel and that is not regarded as a foreign substance by the naked eye. Specifically, those having an average thickness of 1 to 5 μm, an average particle diameter of 10 to 500 μm, and an aspect ratio of 10 to 100 are suitable.
[0012]
The refractive index of the glass powder is about 1.4 to 1.6, although there is a certain range depending on the content of the composition. In contrast, the refractive index of titanium dioxide is around 2.5 for anatase type and around 2.7 for rutile type. In general, reflection tends to occur at the interface where the refractive index changes, so that this glittering pigment easily reflects at the interface between the glass powder and the titanium dioxide thin film and at the interface between this thin film and the matrix gel. Therefore, with this brilliant pigment, reflected light stronger than that of conventionally used pearl mica can be obtained.
[0013]
The higher the refractive index of titanium dioxide, the stronger the reflected light of the brilliant pigment. Therefore, the titanium dioxide is preferably a rutile type. Further, since the rutile type is chemically more stable than the anatase type and has a low photocatalytic activity, if it is a rutile type thin film, the brilliant pigment hardly deteriorates in performance and does not deteriorate the matrix gel that comes into contact. .
[0014]
When the optical thickness of the thin film of titanium dioxide is an integral multiple of a quarter of the wavelength of visible light, the bright pigment exhibits an interference color. This is because the light of the specific wavelength reflected on the surface of the titanium dioxide thin film and the light of the same wavelength reflected on the interface between the thin film and the glass powder reinforce and cancel each other, as is the case with the interference color. Therefore, a desired interference color can be obtained by adjusting the thickness of the titanium dioxide thin film. The thickness of the titanium dioxide thin film is preferably 1 to 200 μm. When the thickness is less than 1 μm, reflection hardly occurs. On the other hand, when the thickness exceeds 200 μm, irregularities on the surface of the thin film due to crystal growth of titanium dioxide cannot be ignored, and scattering of reflected light becomes a problem.
[0015]
As a bright pigment in which the surface of glass flakes is coated with a thin film of titanium dioxide, for example, Metashine (registered trademark) RC series (MC5090RS, MC5090RY, MC5090RR, MC5090RB, MC5090RG, MC1080RS, MC1080RY, MC1080RR, MC1080RB, manufactured by Nippon Sheet Glass Co., Ltd.) , MC1080RG, MC1040RS, MC1040RY, MC1040RR, MC1040RB, MC1040RG, MC1020RS, MC1020RY, MC1020RR, MC1020RB, MC1020RG).
[0016]
The type of the matrix gel is not particularly limited. For example, a gel forming agent composed of an organic polymer such as carboxyvinyl polymer, hydroxyethylcellulose, polyvinylpyrrolidone, chitosan or polyacrylates, and polyoxyethylene polyoxygen Examples thereof include those obtained by mixing and reacting with a gelling agent such as propylene cetyl ether phosphoric acid, polyoxyethylene polyoxypropylene glycol, dextrin fatty acid ester or sodium stearate. Natural polymer compounds such as carrageenan, sodium alginate, juran gum, agar, gelatin and chitosan are also used as gel formers. The gelling agent may be used only when necessary according to the viscosity of the gel former and the intended use of the gel composition.
[0017]
A colorant may be added to the matrix gel in combination with the glitter pigment exhibiting the interference color. For example, by using a colorant that exhibits a color that is complementary to the interference color of the glittering pigment, the appearance of the gel composition can be further deepened. Coloring agents other than glitter pigments include, for example, basic or acidic water-soluble dyes, azo-based, anthraquinone-based or perylene-based oil-soluble dyes, inorganic pigments such as iron oxide or composite oxide, azo-based, and phthalocyanine-based pigments. Organic pigments such as anthraquinone type, indigo type, perylene type or quinacridone type, calcium sulfate type (base crystal is CaS and activator is Bi) or zinc sulfate type (base crystal is ZnS and activator is Cu). Phosphorescent pigments or fluorescent dyes / pigments such as Rhodamine B, Rhodamine 6G, Rhodamine S, Eosine, Basic yellow HG, Brilliant Sulfoflavine FF, Thioflavine or Fluorescein. Further, an achromatic bright pigment that does not exhibit an interference color may be combined with a chromatic colorant.
[0018]
The content of the glitter pigment in the gel composition is preferably from 0.1 to 30% by mass, and more preferably from 0.5 to 10% by mass. When the content is less than 0.1% by mass, the glitter of the gel composition does not improve much. On the other hand, if it exceeds 30% by mass, the glitter feeling becomes too strong, and the design of the gel composition is rather impaired.
[0019]
Means for blending the glitter pigment into the matrix gel is not particularly limited, and any known means can be used as it is. For example, a glitter pigment is added at a stage where the matrix gel has high fluidity (before removing the solvent or before adding the gelling agent, etc.), kneading them uniformly, and removing the solvent to increase the viscosity. And a method of molding into a shape.
[0020]
The gel composition thus produced can be used as it is for a product in which the gel composition has been conventionally used. For example, a fragrance, a deodorant, a repellent, an attractant, an insecticide, a cool agent, an external medicine, a bath cosmetic, a wax product, a cool material and the like can be mentioned. An example of the wax product is an ornamental candle in which a dried flower or the like is embedded in a viscous wax such as syrup, and an example of the bath cosmetic is a transparent soap for face washing.
[0021]
【Example】
Hereinafter, the present invention will be described specifically with reference to examples.
[0022]
(Example 1)
As a matrix gel, 50 cc of Super Hard Gel (colorless and transparent) manufactured by Mandom Co., Ltd. was collected in a sample bottle, and Metashine (registered trademark) MC5090RS manufactured by Nippon Sheet Glass Co., Ltd. as a bright pigment (average thickness: 5 μm average particle) Diameter: 90 μm Average aspect ratio: 18 Thickness of rutile-type titanium dioxide thin film: 60 nm Interference color: silver) (0.5 g) was added, and the mixture was kneaded with a glass rod until it was uniformly dispersed. After the gel composition was left for a while, the design was evaluated by five sensory examiners. In this sensory test, the gel composition was exposed to sunlight during the day, and it was evaluated whether or not it had a glittering feeling and whether or not it had a glittering feeling. The results of the comprehensive evaluation by five sensory examiners are shown in Table 1 below. The evaluation of the design of the gel composition in the following Examples and Comparative Examples is based on comparison observation based on the gel composition prepared in Example 1.
[0023]
(Example 2)
In Example 1, 1 cc of blue watercolor paint manufactured by Pentel was added to the matrix gel as a colorant along with the glitter pigment, and the gel composition was prepared and evaluated in the same manner except for the above. The evaluation results of the sensory test of this gel composition are shown in Table 1 below.
[0024]
(Example 3)
A gel composition was prepared and evaluated in the same manner as in Example 2, except that the coloring agent was changed to black watercolor paint manufactured by Pentel. The results of evaluation of this gel composition are shown in Table 1 below.
[0025]
(Comparative Example 1)
A sensory test was conducted in the same manner as in Example 1 except that the glitter pigment was not added, that is, only the matrix gel. The evaluation results are shown in Table 1 below.
[0026]
(Comparative Example 2)
In Example 1, instead of the bright pigment MC5090RS, Metashine (registered trademark) ME5090NS manufactured by Nippon Sheet Glass Co., Ltd. (average thickness: 5 μm average particle size: 90 μm average aspect ratio: 18 thickness of nickel thin film: 260 nm) : Grayish black), and a gel composition was prepared and evaluated in the same manner. The results of the evaluation are shown in Table 1 below.
[0027]
(Comparative Example 3)
In the same manner as in Example 2, except that the glitter pigment was not added, that is, a matrix gel to which a blue watercolor was added was prepared and evaluated. The evaluation results are shown in Table 1 below.
[0028]
(Comparative Example 4)
In the same manner as in Example 3, except that no glittering pigment was added, that is, a matrix gel prepared by adding a black watercolor paint was evaluated. The evaluation results are shown in Table 1 below.
[0029]
(Comparative Example 5)
A gel composition was prepared in the same manner as in Example 1, except that flaky aluminum powder (Alpaste 0100X manufactured by Toyo Aluminum Co., Ltd., average thickness 0.3 μm, average particle diameter 45 μm) was used instead of the glitter pigment. And evaluated. The evaluation results are shown in Table 1 below.
[0030]
[Table 1]
By contrasting Examples 1 to 3 with Comparative Examples 1 to 5, the use of a brilliant pigment in which flaky glass is coated with a thin film of titanium dioxide enhances the brilliant feeling of the gel composition and improves its design. It can also be seen that can be improved.
[0032]
By comparing Example 1 with Comparative Example 2, it can be seen that when a pigment having no glitter is used, the glittery feeling of the gel composition is almost lost and the design property is also impaired.
[0033]
By comparing Example 1 and Comparative Example 5, if a glitter pigment having glass flakes as a component is used, problems such as a lack of a feeling of a foreign substance or a sense of depth as in the case of using aluminum powder are obtained. It can be seen that no problem occurs.
[0034]
【The invention's effect】
