Abstract
Description
本発明は、爪を綺麗に見せる水性美爪料組成物に関し、ネイル用アートペン、特に、直液式のペン型容器に充填した板状顔料を含有する水系組成分の経時的なハードケーキ化を防止し、板状顔料の再分散性を向上させることができる水性美爪料組成物に関する。 The present invention relates to a water-based nail polish composition that makes nails look beautiful, and to make a hard cake over time of an aqueous composition containing a plate-like pigment filled in an art pen for a nail, especially a direct liquid pen-type container It is related with the aqueous | water-based beautiful nail material composition which can prevent reinforce and can improve the redispersibility of a plate-shaped pigment.
近年、水性美爪料組成物は、有機溶剤系の美爪料組成物に較べ、爪や皮膚が荒れるという身体への影響も少なく、数多くの水性美爪料組成物が開発されてきている。
従来、光輝性の水性美爪料組成物として、光輝性を得るための顔料としてパール顔料、アルミニウム顔料などを用いた場合、最低でも粒子径３μｍ以上となることが必要である。このような大きい粒子径となる顔料を配合する水性美爪料組成物では顔料が沈降してハードケーキが発生し、その結果、水性美爪料塗布具において再分散のためのボールや棒などの撹拌部材を複数回撹拌する必要がある。
In recent years, the aqueous beauty nail composition has less influence on the body such as nail and skin roughening than the organic solvent-based beauty nail composition, and many aqueous beauty nail compositions have been developed.
Conventionally, when a pearl pigment, an aluminum pigment, or the like is used as a pigment for obtaining glitter, as a glittering aqueous beauty nail composition, it is necessary to have a particle size of 3 μm or more at least. In an aqueous beauty nail composition containing a pigment having such a large particle size, the pigment settles to generate a hard cake. As a result, a ball or stick for redispersion in an aqueous beauty nail applicator is used. It is necessary to stir the stirring member a plurality of times.
これらの光を反射させて光輝性を得るパール顔料等は、通常の有機顔料や無機顔料よりもその粒径は大きく、主に板状顔料から構成されるものであるため、これらの板状顔料を含有する水性美爪料組成物では、長期間の静置や温度変化の大きい環境での保管は、沈降した板状顔料が固いハードケーキを形成し、撹拌部材が動かなくなる現象やそれによる再分散性の悪化の問題が起こりやすい。これは、板状顔料が高比重大粒径であることから沈降しやすく、また、平板であるため沈降する際に平面側が向かい合って積み重なる層状構造になるため、顔料同士の接触面積が大きく、接触抵抗も大きくなり、さらに、顔料の分散剤が絡み合い、接触面の接着をより強固にするため、固い沈降（ハードケーキ）を作りやすいからである。 The pearl pigments, etc., which obtain the luster by reflecting these lights, have a particle size larger than that of ordinary organic pigments and inorganic pigments, and are mainly composed of plate pigments. In the case of a water-based nail care composition containing a long-term standing or storage in an environment with a large temperature change, the settled plate-like pigment forms a hard hard cake, and the stirring member does not move or is The problem of deterioration of dispersibility is likely to occur. This is because the plate-like pigment has a high specific critical particle size, so it is easy to settle, and since it is a flat plate, it has a layered structure in which the flat sides face each other when it settles, so the contact area between the pigments is large and the contact is large. This is because the resistance is increased, and the pigment dispersant is entangled, and the adhesion on the contact surface is further strengthened, so that it is easy to form a hard sediment (hard cake).
これらの課題を解決しようとした水性美爪料組成物等としては、１）少なくとも、水と、水溶性樹脂と、平板状顔料と、エマルジョン樹脂と、保湿剤と、防菌剤とを含む水系美爪料において、表面張力が３３ｄｙｎ／ｃｍ以下であって、更に結晶セルロースを含み、温度２５℃でのコーンプレート型粘度計によるずり速度３８．３ｓ−１のときの粘度が１０〜４０ｍＰａ・ｓ、ずり速度３８３ｓ−１のときの粘度が５〜２０ｍＰａ・ｓとなる水系美爪料組成物（例えば、本出願人による特許文献１参照）、２）微細結晶セルロースを酸化チタン、セリサイトなどの無機顔料や、レーキレッドなどの有機顔料、ナイロンパウダーなどの樹脂粉体の表面に付着または被覆してなる化粧料用顔料を含有してなることを特徴とする化粧料（例えば、特許文献２参照）が知られている。 As an aqueous beauty nail composition intended to solve these problems, 1) an aqueous system containing at least water, a water-soluble resin, a flat pigment, an emulsion resin, a humectant, and a fungicide. The beauty nail material has a surface tension of 33 dyn / cm or less, further contains crystalline cellulose, and has a viscosity of 10 to 40 mPa · s at a shear rate of 38.3 s −1 with a cone plate viscometer at a temperature of 25 ° C. , A water-based beauty nail material composition having a viscosity of 5 to 20 mPa · s at a shear rate of 383 s −1 (see, for example, Patent Document 1 by the present applicant), 2) Microcrystalline cellulose such as titanium oxide and sericite Cosmetics comprising an inorganic pigment, an organic pigment such as lake red, or a cosmetic pigment formed by adhering or covering the surface of a resin powder such as nylon powder (for example, Patent reference 2) it has been known.
しかしながら、上記特許文献１では、経時前の平板状顔料の再分散性は良好となるものであるが、長期間の高温経時によって美爪料組成物の再分散性が悪くなることがあるなど若干の課題が未だあるのが現状である。
また、上記特許文献２の化粧料に用いる顔料は、本願発明の近接技術を開示するものであるが、水性美爪料に配合して初期及び経時後の再分散性が良好となることについては全く記載も示唆もされていない。また、球状あるいは塊状の顔料を処理して隙間なく処理されていることについての開示はあるが、板状顔料を処理したものについては開示されていない。実際には、当該特許文献２に基づく処理方法による処理顔料（製造実施例１）の状態を電子顕微鏡（×３５０００倍）でみると、図４に示すように、一部が露出した状態、具体的には、一部しか被覆されていない状態である。このため、水性の美爪料に配合し、低粘度の組成物とした際、ハードケークを生じ、再分散性が悪くなることが予想される。
However, in Patent Document 1, the redispersibility of the tabular pigment before aging is improved, but the redispersibility of the beauty nail composition may be deteriorated due to long-term high temperature aging. However, there are still some issues.
In addition, the pigment used in the cosmetic of Patent Document 2 discloses the proximity technique of the present invention. However, when it is blended in an aqueous beauty nail preparation, the redispersibility after initial and lapse of time is improved. There is no description or suggestion. Further, although there is a disclosure that a spherical or block pigment is processed without gaps, a plate pigment is not disclosed. Actually, when the state of the treated pigment (Production Example 1) by the treatment method based on Patent Document 2 is viewed with an electron microscope (× 35000 times), as shown in FIG. Specifically, it is in a state where only a part is covered. For this reason, when it mix | blends with an aqueous | water-based beauty nail material and it is set as a low-viscosity composition, it will anticipate that a hard cake will be produced and redispersibility will worsen.
本発明は、上記従来技術の課題等に鑑み、これを解消しようとするものであり、水性美爪料組成物として、板状顔料を含有した際の経時的なハードケーキ形成、これによる再分散性の悪化を解決し、優れた再分散性、終筆性、隠ぺい力に優れた水性美爪料組成物を提供することを目的とする。 The present invention is to solve this problem in view of the above-mentioned problems of the prior art, and as an aqueous beauty nail composition, hard cake formation over time when a plate-like pigment is contained, and redispersion thereby An object of the present invention is to provide a water-based beauty nail composition having excellent redispersibility, final writing properties and hiding power.
本発明者らは、上記従来の課題等に鑑み、これを解消しようとするものであり、板状粒子の密着を阻害しようと結晶セルロースの配合を試みたが、上記多糖類が板状粒子間をすり抜けて密着を阻害するに至らなかった。このようなさまざまな検討を行った結果、板状顔料が密着しないよう、顔料表面に立体障害となる物質を付着させることで粒子同士の密着を抑制し、再分散性等を良好にすることを見出し、本発明を完成するに至った。 In view of the above-mentioned conventional problems and the like, the present inventors have attempted to solve this problem, and tried to mix crystalline cellulose in an attempt to inhibit the adhesion of plate-like particles. It was not able to pass through and obstruct adhesion. As a result of such various studies, the adhesion of particles is suppressed by attaching a substance that causes steric hindrance to the pigment surface so that the plate pigment does not adhere, and the redispersibility and the like are improved. The headline and the present invention were completed.

以下に、本発明の実施の形態を詳しく説明する。
本発明の水性美爪料組成物は、少なくとも水不溶性物質を表面に被覆された板状顔料を３〜２０質量％と、水を含有することを特徴とするものである。
Hereinafter, embodiments of the present invention will be described in detail.
The aqueous beauty nail composition of the present invention is characterized by containing at least 3 to 20% by mass of a plate-like pigment having a surface coated with a water-insoluble substance, and water.
本発明で用いる少なくとも水不溶性物質を表面に被覆された板状顔料とは、水不溶性で、かつ板状顔料の面接触を立体的に阻害しうる物質であり、例えば、パール顔料、アルミニウム粉顔料、金属または金属酸化物コーティングガラスフレーク、及びアルミコーティングポリエステルフィルムなどの板状顔料に、少なくとも上記水不溶性物質を上記板状顔料の表面に被覆したものである。 The plate-like pigment whose surface is coated with at least a water-insoluble substance used in the present invention is a substance that is water-insoluble and can sterically hinder the surface contact of the plate-like pigment. For example, a pearl pigment, an aluminum powder pigment A plate-like pigment such as a metal or metal oxide-coated glass flake and an aluminum-coated polyester film is coated with at least the water-insoluble substance on the surface of the plate-like pigment.
本発明における水不溶性物質としては、高分子であるセルロース、ヘミセルロース、リグニン、キチン、キトサン、ラテックスやシリカ、アルミナ、シリコーンから選ばれる少なくとも１種が挙げられる。
この水不溶性物質を上記板状顔料の表面に被覆する方法等としては、例えば、１）水不溶性物質と板状顔料を混合した水スラリー状物をスプレードライヤーにて噴霧乾燥させ、板状顔料表面に水不溶性物質を接着させる方法（以下、「製法１」という）、２）酸性、あるいは塩基性水溶液に可溶な物質をｐＨ調整して水に溶かし、酸・あるいは塩基で不溶化の方向にｐＨを傾け、板状顔料表面に水不溶性物質を析出させる方法（以下、「製法２」という）により行うことができる。
この水不溶性物質の表面被覆量は、少なすぎるとハードケーキ抑制による再分散性の効果が得られず、一方、多すぎるとパール感が減少するだけでなく、パール表面が点接触にならず面接触になり再分散性の効果が得られなくなる。そのため、水不溶性物質の表面被覆量は、板状顔料の表面被覆率（表面処理時の質量％から算出）として、０．１〜１０％とし、好ましくは、０．５〜８％、更に好ましくは、１〜７％の範囲とする。
Examples of the water-insoluble substance in the present invention include at least one selected from cellulose, hemicellulose, lignin, chitin, chitosan, latex, silica, alumina, and silicone, which are polymers.

If the surface coating amount of this water-insoluble substance is too small, the effect of redispersibility by suppressing hard cake cannot be obtained. On the other hand, if the amount is too large, not only the pearl feeling will be reduced, but the pearl surface will not be in point contact. It becomes contact and the effect of redispersibility cannot be obtained. Therefore, the surface coating amount of the water-insoluble substance is 0.1 to 10%, preferably 0.5 to 8%, more preferably, as the surface coverage of the plate-like pigment (calculated from mass% at the time of surface treatment). Is in the range of 1-7%.

The plate-like pigment coated with the water-insoluble substance obtained above used in the present invention can confirm the above crystalline crystals on the surface observed with an electron microscope (× 35,000 times).
As a method for distinguishing between a plate-like pigment whose surface is coated with a water-insoluble substance and an uncoated plate-like pigment in the present invention, redispersibility cannot be obtained in a system in which an uncoated plate-like pigment is blended. It can be confirmed that good redispersibility can be obtained in a system in which a water-insoluble substance is used for the surface coating of plate-like particles.

If the content of the coated plate-like pigment is less than 3%, the glitter and hiding power are poor. On the other hand, if it exceeds 20%, the plate-like pigment is in the applicator pen core, that is, the writing is poor. This is not preferable. In the case of a plate-like pigment that has not been surface-treated, the formation of a hard cake is promoted.
