Description
本発明は、シリコーンエラストマーで表面処理された粉体及びそれを含有する化粧料に関する。 The present invention relates to a powder surface-treated with a silicone elastomer and a cosmetic containing the same.
従来、メチルハイドロジェンポリシロキサンなどのシリコーンオイルを、粉体表面に被覆し、加熱して架橋させる粉体表面処理技術は、粉体に適度な滑り感やなめらかさ、撥水性を与えるものとして広く行われている（特許文献１）。 Conventionally, powder surface treatment technology in which silicone oil such as methylhydrogenpolysiloxane is coated on the surface of the powder and heated to crosslink is widely used to give powder an appropriate slipperiness, smoothness and water repellency. (Patent Document 1).
近年では、シリコーンが三次元に架橋したシリコーンエラストマーを、粉体表面に被覆処理しようとする試みが行われている。シリコーンエラストマーは、柔らかい感触で弾力があるため、これを粉体に処理することで感触の向上やぼかし効果などが期待できる。 In recent years, an attempt has been made to coat the surface of a powder with a silicone elastomer in which silicone is three-dimensionally cross-linked. Silicone elastomer has a soft feel and elasticity. By treating this with powder, an improvement in feel and a blurring effect can be expected.
しかし、このシリコーンエラストマーは凝集しやすいため、均一に被覆するのが難しい。そのため、揮発性炭化水素に分散させて被覆する方法や、シリコーンレジンを媒体として粉体にエラストマーを被覆する方法などが挙げられている（特許文献２、３）。 However, since this silicone elastomer easily aggregates, it is difficult to coat it uniformly. For this reason, a method of coating by dispersing in a volatile hydrocarbon, a method of coating an elastomer on a powder using a silicone resin as a medium, and the like are cited (Patent Documents 2 and 3).
また本出願人は、これまでにシリコーンエラストマーを均一に粉体に表面処理する技術として、分散媒中に分散させたシリコーンエラストマーにせん断力を加えることにより粉砕物液を作製し、粉体と混合させることで目的の表面処理粉体を得る方法を報告している（特許文献４）。 In addition, the present applicant has prepared a pulverized product liquid by applying shearing force to a silicone elastomer dispersed in a dispersion medium and mixing it with the powder as a technique for uniformly treating a silicone elastomer to a powder so far. A method for obtaining the desired surface-treated powder is reported (Patent Document 4).
しかしながら、特許文献４の方法においてシリコーンエラストマーを分散させる分散媒として主にイソプロピルアルコールを用いていたが、分散媒にイソプロピルアルコールを用いた表面処理粉体は、肌への付着性には優れているが、柔らかさ、なめらかさ、伸びのよさなどの点で十分に満足できるものではなかった。また、分散媒として大量にイソプロピルアルコールを使用すると、コストや製造中の廃液の面で問題が生じるといった欠点を有していた。
従って、本発明の課題は肌への付着性だけでなく、柔らかさ、なめらかさ、伸びのよさ等が改善されたシリコーンエラストマー表面処理粉体及びこれを含有する化粧料を提供することにある。
However, in the method of Patent Document 4, isopropyl alcohol was mainly used as a dispersion medium for dispersing the silicone elastomer, but the surface-treated powder using isopropyl alcohol as the dispersion medium is excellent in adhesion to the skin. However, it was not satisfactory in terms of softness, smoothness, and good elongation. Further, when isopropyl alcohol is used in a large amount as a dispersion medium, there is a disadvantage that a problem occurs in terms of cost and waste liquid during production.
Accordingly, an object of the present invention is to provide a silicone elastomer surface-treated powder improved not only in adhesion to the skin but also in softness, smoothness, good elongation and the like, and a cosmetic containing the same.
そこで、従来の問題点を解決するべく鋭意検討した結果、シリコーンエラストマーを乳化能を有するものとし、且つ分散媒を水を含むものにすることで上記課題が解決できることを見出した。また、あらかじめ混合する粉体を水を用いてスラリー化しておくことで、粉体同士の凝集を防いで均一な混合物を作製することが可能となった。得られた表面処理粉体は、従来品よりも適度な滑り性と柔らかい感触を有し、しっとり感に優れ、肌への付着力に優れており、またこの表面処理粉体を化粧料に配合したところ、肌への伸びのよさとしっとりとした感触を有し、粉っぽさがなく、滑らかで均一な仕上がりで、化粧もちに優れた化粧料が得られることを見出した。 Therefore, as a result of intensive studies to solve the conventional problems, it has been found that the above problem can be solved by making the silicone elastomer have an emulsifying ability and the dispersion medium contains water. Moreover, it became possible to produce a uniform mixture by preventing the powder from aggregating by slurrying the powder to be mixed in advance with water. The obtained surface-treated powder has moderate slipperiness and soft touch compared to conventional products, is moist and has excellent adhesion to the skin, and this surface-treated powder is formulated in cosmetics. As a result, it has been found that a cosmetic material having a smooth and uniform finish, having a smooth and uniform finish, having a moist feeling and a smooth feel to the skin can be obtained.
即ち、本発明は、水を含む分散媒中に分散させた架橋型ポリエーテル変性シリコーン及び架橋型ポリグリセリン変性シリコーンから選ばれるシリコーンエラストマー０．１〜２０質量部で、粉体１００質量部を被覆処理して得られる表面処理粉体を提供するものである。
また、本発明は、該表面処理粉体を含有する化粧料を提供するものである。
That is, the present invention covers 100 parts by mass of a powder with 0.1 to 20 parts by mass of a silicone elastomer selected from a crosslinked polyether-modified silicone and a crosslinked polyglycerin-modified silicone dispersed in a water-containing dispersion medium. The present invention provides a surface-treated powder obtained by processing.
The present invention also provides a cosmetic containing the surface-treated powder.
本発明により、弾力があり柔らかい感触を有し、しっとり感・肌への付着力に優れているだけでなく、適度な滑り性をも併せ持つ表面処理粉体を作製することができ、その表面処理粉体を配合することで、伸びのよさとしっとりとした感触を有し、粉っぽさがなく、均一な仕上がりで、化粧もちに優れた化粧料を提供することができる。 According to the present invention, it is possible to produce a surface-treated powder having a soft and soft feel, not only having a moist feeling and adhesion to the skin, but also having an appropriate slipperiness. By blending the powder, it is possible to provide a cosmetic material that has a good stretch and a moist feel, has no powderiness, has a uniform finish, and is excellent in makeup.
以下、本発明の実施の形態を詳述する。 Hereinafter, embodiments of the present invention will be described in detail.

用いるシリコーンエラストマーの量は、粉体１００質量部に対し、０．１〜２０質量部であり、好ましくは１〜１０質量部である。使用割合が、０．１質量部未満であると、本発明の効果が十分に得られず、また２０質量部を超えて用いると、肌への付着性や感触において優れたものが得られない。 The amount of the silicone elastomer used is 0.1 to 20 parts by mass, preferably 1 to 10 parts by mass with respect to 100 parts by mass of the powder. If the use ratio is less than 0.1 parts by mass, the effects of the present invention cannot be obtained sufficiently, and if it is used in excess of 20 parts by mass, no excellent adhesiveness or feel to the skin can be obtained. .
本発明で用いる前記シリコーンエラストマーの分散媒は、水を用いることが必須であるが、水単独、又は水と、メチルアルコール、エチルアルコール、イソプロピルアルコール、ブタノールなどの低級アルコール；フッ素系油剤；トリクロロエチレン、ジクロロメタンなどの塩素系油剤；ヘキサン、シクロヘキサン、トルエン、キシレン、イソドデカン、流動イソパラフィン、流動パラフィン、スクワランなどの炭化水素系油剤；デカメチルシクロペンタシロキサン、ドデカメチルシクロヘキサシロキサン、ジメチルポリシロキサンなどのシリコーン系油剤；トリ（カプリル／カプリン酸）グリセリルなどのエステル系油剤などの混合溶剤を用いることもできる。このうち、水単独、又は水と炭化水素系油剤、シリコーン系油剤、エステル系油剤の混合溶剤を用いるのがより好ましい。分散媒中における水の含有量は、１０〜１００質量％が好ましく、より好ましくは２０〜７５質量％であり、さらに好ましくは３０〜５０質量％である。 As the dispersion medium of the silicone elastomer used in the present invention, it is essential to use water, but water alone or water and lower alcohols such as methyl alcohol, ethyl alcohol, isopropyl alcohol, butanol; fluorine-based oil agent; trichloroethylene, Chlorine oils such as dichloromethane; hydrocarbon oils such as hexane, cyclohexane, toluene, xylene, isododecane, liquid isoparaffin, liquid paraffin, squalane; silicones such as decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, dimethylpolysiloxane Oil agent; Mixed solvents such as ester oil agents such as tri (capryl / capric acid) glyceryl can also be used. Among these, it is more preferable to use water alone or a mixed solvent of water and a hydrocarbon oil agent, a silicone oil agent, and an ester oil agent. 10-100 mass% is preferable, as for content of the water in a dispersion medium, More preferably, it is 20-75 mass%, More preferably, it is 30-50 mass%.
水を含む分散媒中の前記シリコーンエラストマー濃度は、製造上の問題や、水を含む分散媒中に安定的にシリコーンエラストマーを粉砕・分散させる点から、５〜２５質量％が好ましく、さらに１０〜２０質量％が好ましい。 The concentration of the silicone elastomer in the dispersion medium containing water is preferably 5 to 25% by mass, more preferably 10 to 25% by mass from the viewpoint of manufacturing problems and the point of stably pulverizing and dispersing the silicone elastomer in the dispersion medium containing water. 20 mass% is preferable.
前記シリコーンエラストマー分散液は、前記シリコーンエラストマーを、水を含む分散媒中でせん断力を加えることによりその凝集塊を粉砕して製造するのが好ましい。その際、市販されているもので、例えば信越化学工業社製のＫＳＧ−３２０は、（ＰＥＧ−１５／ラウリルジメチコン）クロスポリマー約２５質量％が、イソドデカン約７５質量％に分散された状態で入手できるが、これにさらに水を加えて粉砕処理を行うのが好ましい。 The silicone elastomer dispersion is preferably produced by pulverizing the agglomerates of the silicone elastomer by applying a shearing force in a dispersion medium containing water. At that time, for example, KSG-320 manufactured by Shin-Etsu Chemical Co., Ltd. is obtained in a state where about 25% by mass of (PEG-15 / lauryl dimethicone) crosspolymer is dispersed in about 75% by mass of isododecane. Although it is possible, it is preferable to add water to this and perform a pulverization treatment.
粉砕の方法としては、前記シリコーンエラストマーの凝集を解くことができるせん断力がある方法がよく、この条件を満たせばとくに制限はされない。例えば、容器に前記シリコーンエラストマーと水を含む分散媒、セラミックの球を適量入れ、上下に激しく震とうすることができるペイントシェーカー（ＹＳ−ＬＤ、ヤヨイ社製）を用いたり、媒体ミルを用いることが望ましい。媒体ミルの例としては、ビーズミル、サンドミル、ダイノーミル（シンマルエンタープライゼス社製）、ボールミル、マイクロス（奈良機械製作所社製）などが挙げられる。尚、マイクロスとは、ケーシングとその中で回転する主軸及び主軸回転軸により連動公転する副軸から構成されており、各副軸には僅かのギャップを持って多数のリング状粉砕媒体が取り付けられた装置であり、粉砕媒体の動きを持つリングは主軸の回転により、遠心力作用でケーシング内壁面に押しつけられながら自転・公転することによって粉砕する装置であり、高粘性体が粉砕可能である。 As the pulverization method, a method having a shearing force capable of releasing the aggregation of the silicone elastomer is preferable, and there is no particular limitation as long as this condition is satisfied. For example, use a paint shaker (YS-LD, manufactured by Yayoi Co., Ltd.) that can put a proper amount of dispersion medium containing ceramic elastomer and water and ceramic balls in a container and shake vigorously up and down, or use a media mill. Is desirable. Examples of the media mill include a bead mill, a sand mill, a dyno mill (manufactured by Shinmaru Enterprises), a ball mill, and Micros (manufactured by Nara Machinery Co., Ltd.). Micros is composed of a casing, a main shaft that rotates in the casing, and sub-shafts that revolve in conjunction with the main-shaft rotation shaft. A large number of ring-shaped grinding media are attached to each sub-shaft with a slight gap.
