Description

メイクアップ化粧料Makeup cosmetics
　本発明は、メイクアップ化粧料に関する。 The present invention relates to makeup cosmetics.
　ファンデーションや化粧下地等のメイクアップ化粧料の重要な役割としては、肌の血行不良や色素沈着などによるくすみをカバーし、光散乱（ソフトフォーカス）させることで肌の凹凸やシワなどの肌の欠点を隠すことで、透明感や素肌感を高めることが期待されている。 An important role of makeup cosmetics such as foundations and makeup bases is to cover dullness caused by poor blood circulation and pigmentation, and to cause light defects (skin unevenness and wrinkles) by scattering light (soft focus). It is expected to improve transparency and bare skin feeling by hiding.
　従来ソフトフォーカス効果を得るために、シリカやアルミナ、マイカや酸化チタンなどの白色の無機粉末材料や、ポリエチレン粉末などの化石燃料由来の有機粉末材料などを充填剤として用いることが知られている（特許文献１） Conventionally, in order to obtain a soft focus effect, it is known that white inorganic powder materials such as silica, alumina, mica and titanium oxide, and organic powder materials derived from fossil fuels such as polyethylene powder are used as fillers ( Patent Document 1)
特開２００５－５３９０６号JP 2005-53906 A
　しかしながらソフトフォーカス効果を高く得るために、酸化チタンなどの白色顔料を添加した化粧料では、化粧膜がツヤのないマットな状態になり易く、肌がくすんで見えるという欠点があった。また、ポリエチレン粉末などの化石燃料由来の有機粉末材料を添加した化粧品では、有機粉末材料が生分解性を有していないため、環境への悪影響が懸念されている。 However, in order to obtain a high soft focus effect, cosmetics to which a white pigment such as titanium oxide is added have a drawback that the cosmetic film tends to be a matte-free state and the skin looks dull. Further, in cosmetics to which an organic powder material derived from fossil fuel such as polyethylene powder is added, since the organic powder material does not have biodegradability, there is a concern about an adverse effect on the environment.
　そこで、本発明は、良好なソフトフォーカス効果を持ち、自然な仕上がりとなる化粧膜を得ることができ、更に環境に優しいメイクアップ化粧料を提供することを課題とする。 Therefore, an object of the present invention is to provide a makeup cosmetic that has a good soft focus effect, can obtain a natural finish, and is more environmentally friendly.

＜セルロース顆粒＞
　本発明において、セルロース顆粒はセルロース系の原料を微小な顆粒にしたものであれば特に限定さればいが、セルロース繊維を原料とした顆粒（セルロース繊維を含有するセルロース顆粒：以下単に「セルロース顆粒」ということがある。）であることが好ましい。このセルロース繊維を含有するセルロース顆粒は、造粒条件の調整により肌の凹凸やシワに適するように平均粒子径を調整できる。 <Cellulose granules>
In the present invention, the cellulose granule is not particularly limited as long as it is a cellulosic raw material made into a fine granule, but a granule made from cellulose fiber (cellulose cellulose containing cellulose fiber: hereinafter simply referred to as “cellulose granule”). Is preferred.). Cellulose granules containing cellulose fibers can be adjusted in average particle size so as to be suitable for skin irregularities and wrinkles by adjusting the granulation conditions.
　また、セルロース顆粒は、不均一な形状のセルロース繊維を含んでおり、多孔質の構造となっているため、光の散乱性が高く、優れたソフトフォーカス効果が発現する。さらに、親水基を持つセルロース原料からなるため、保湿性に優れ、肌に対する触感がしっとりとして滑らかとなり易い特性も有する。 In addition, since the cellulose granule contains cellulose fibers having a non-uniform shape and has a porous structure, it has a high light scattering property and exhibits an excellent soft focus effect. Further, since it is made of a cellulose raw material having a hydrophilic group, it has excellent moisture retention and has a characteristic that the touch to the skin is easily moistened and smooth.
　このセルロース顆粒の含有量はその期待される効果により適宜調節することができるが、化粧料に含まれる化粧料粉体及びセルロース顆粒の全量に対し、０．１～６０重量％の範囲で含むことが好ましく、より好ましくは０．３～５０重量％であり、さらに好ましくは１～４０重量％である。 The cellulose granule content can be appropriately adjusted depending on the expected effect, but it should be contained in the range of 0.1 to 60% by weight with respect to the total amount of the cosmetic powder and cellulose granule contained in the cosmetic. Is more preferably 0.3 to 50% by weight, and still more preferably 1 to 40% by weight.
＜セルロース繊維を含有するセルロース顆粒＞
　セルロース繊維を造粒して得られるセルロース繊維を含有するセルロース顆粒の平均粒子径は、その用いられる用途や効果によって好ましい範囲が異なるが、平均粒子径５～１００μｍの範囲であることが好ましく、１０～１００μｍの範囲がより好ましく、１０～７０μｍの範囲がさらに好ましく、１０～５０μｍの範囲が特に好ましい。平均粒子径５～１００μｍのセルロース顆粒を用いることで、優れたソフトフォーカス効果を得ることができる。また、セルロース顆粒の真球度は特に限定されないが、通常０．１～１．０の範囲であり、好ましくは０．３～１．０の範囲で調整されることが好ましい。セルロース顆粒の真球度が小さい方がソフトフォーカス効果を発現しやすく、真球度が高い方が使用感に優れる傾向にある。このため、メイクアップ化粧品に含有されるセルロース顆粒の平均粒子径及び真球度は求められる品質にあせて上記範囲内で適宜調整されることが好ましい。 <Cellulose granules containing cellulose fibers>
The average particle size of cellulose granules containing cellulose fibers obtained by granulating cellulose fibers varies depending on the use and effect used, but is preferably in the range of 5 to 100 μm. The range of ˜100 μm is more preferable, the range of 10 to 70 μm is more preferable, and the range of 10 to 50 μm is particularly preferable. By using cellulose granules having an average particle size of 5 to 100 μm, an excellent soft focus effect can be obtained. The sphericity of the cellulose granule is not particularly limited, but is usually in the range of 0.1 to 1.0, and preferably adjusted in the range of 0.3 to 1.0. The smaller the sphericity of the cellulose granules, the easier it is to develop a soft focus effect, and the higher the sphericity, the better the usability. For this reason, it is preferable that the average particle diameter and sphericity of the cellulose granules contained in the makeup cosmetics are appropriately adjusted within the above range depending on the required quality.
　本発明において示される平均粒子径は、例えば、レーザー回折・散乱式粒子径分布測定装置（例えば、マイクロトラックＭＴ３３００ＥＸ、マイクロトラックベル株式会社）を使用し、測定に用いる分散媒としてメタノールを用い、試料０．２ｇを加えて測定し、堆積累計５０％粒子径を平均粒子径として求めることができる。 The average particle size shown in the present invention is, for example, using a laser diffraction / scattering type particle size distribution measuring device (for example, Microtrack MT3300EX, Microtrack Bell Co., Ltd.), using methanol as a dispersion medium used for measurement, Measurement can be performed by adding 0.2 g, and the 50% cumulative particle diameter can be determined as the average particle diameter.
　なお、真球度は、光学顕微鏡（製品名：デジタルマイクロスコープＶＨＸ－６００、キーエンス社製）を用い、観察対象のセルロース顆粒の画像データを取得し、その後得られた画像データ中のセルロース顆粒を、Ｉｍａｇｅ　ＨｙｐｅｒＩＩ（デジモ社製）を用いて画像解析して得られる。その様な真球度は、画像解析により求められるセルロース顆粒の面積Ａと、計算で求められるセルロース顆粒の最大長径を直径とする真球形状とみなした際の面積Ｂとから、真球度＝Ａ／Ｂとして得ることができる。よって、真球度が１に近づくほど真球形状に近く、１から遠ざかるほど不定形状となる。なお、セルロース顆粒は２０個を観察し、真球度は各粒子の平均値を示した。 Note that the sphericity is obtained by obtaining image data of cellulose granules to be observed using an optical microscope (product name: Digital Microscope VHX-600, manufactured by Keyence Corporation), and then obtaining cellulose granules in the obtained image data. It is obtained by image analysis using Image HyperII (manufactured by Digimo). Such sphericity is calculated from the area A of the cellulose granule obtained by image analysis and the area B when it is regarded as a spheric shape having the maximum major axis of the cellulose granule obtained by calculation as a diameter. It can be obtained as A / B. Therefore, the closer the sphericity degree is to 1, the closer it is to a true sphere shape, and the farther away from 1, the more irregular the shape becomes. In addition, 20 cellulose granules were observed, and the sphericity was an average value of each particle.
　また、セルロース顆粒の乾式硬度は特に限定されるものでは、求められるメイクアップ時の使用感により、１～３００ｇの範囲、好ましくは２０～２００ｇｆの範囲で適宜調整することが好ましい。なお、乾式硬度測定は粒子顆粒硬度計（製品名：グラノ、岡田精工株式会社製）を用い、１個のセルロース顆粒の圧潰強度のピーク値を測定し、粒子２０個の平均値を乾式硬度とした。 In addition, the dry hardness of the cellulose granules is not particularly limited, and it is preferably adjusted as appropriate in the range of 1 to 300 g, preferably 20 to 200 gf, depending on the required use feeling during makeup. The dry hardness measurement was performed using a particle granule hardness meter (product name: Grano, manufactured by Okada Seiko Co., Ltd.) to measure the peak value of the crushing strength of one cellulose granule, and the average value of 20 particles was determined as the dry hardness. did.
　この乾式硬度は、セルロース繊維の平均重合度を適宜選択することによっても調整することができる。 This dry hardness can also be adjusted by appropriately selecting the average degree of polymerization of the cellulose fibers.
　本発明のメイクアップ化粧料に配合されるセルロース顆粒は、後述するセルロース繊維を造粒して得ることができ、所望の効果を阻害しない範囲において、セルロース繊維同士の結着性を向上させる結合剤（バインダーともいう。）を含有させてもよい。このような結合剤としては、有機系バインダー、無機系バインダーなどを例示することができる。 The cellulose granule to be blended in the makeup cosmetic of the present invention can be obtained by granulating the cellulose fiber described later, and is a binder that improves the binding property between the cellulose fibers as long as the desired effect is not inhibited. (Also referred to as a binder) may be included. Examples of such binders include organic binders and inorganic binders.
　また、本発明の化粧料に用いられるセルロース顆粒は、所望の効果を阻害しない範囲で、香料、崩壊助剤、造粒促進剤、賦形剤などの他の添加剤を含有し造粒してもよい。 In addition, the cellulose granules used in the cosmetic of the present invention are granulated by containing other additives such as a fragrance, a disintegration aid, a granulation accelerator, and an excipient as long as the desired effects are not impaired. Also good.
　しかしながら、この様な結合剤などを配合すると、排水の汚染につながる可能性もあり、環境負荷の観点からは、少ないほど好ましい。また、結合剤などを用いた場合、セルロース繊維同士の結着が強くなりすぎるため、メイクアップ化粧時の感触が悪化する可能性が有る。 However, if such a binder or the like is blended, there is a possibility that it may lead to waste water contamination, and it is preferable that the amount is smaller from the viewpoint of environmental load. In addition, when a binder or the like is used, the binding between the cellulose fibers becomes too strong, and the touch during makeup makeup may be deteriorated.
　そのため、本発明の好ましい一形態としては、セルロース顆粒としてセルロース繊維同士を結合させるための結合剤を含まない造粒物を用いる形態が挙げられる。 Therefore, as a preferred embodiment of the present invention, a form using a granulated product that does not contain a binder for binding cellulose fibers together as a cellulose granule can be mentioned.
　下記に詳説するセルロース繊維とセルロース顆粒の製法を採用することによって、実質的にセルロース繊維のみで造粒されたセルロース顆粒とすることができる。結着剤などの余分な成分を含まず、しかも天然素材であるセルロース繊維を利用するので、環境に対する負荷を低減できる。また、実質的にセルロース繊維のみで造粒されたセルロース顆粒を用いることにより、安全性の高い化粧用組成物とすることができ、使用者に対する安心感を与えることができる。 By adopting the method for producing cellulose fibers and cellulose granules described in detail below, it is possible to obtain cellulose granules that are substantially granulated with only cellulose fibers. Since it does not contain extra components such as a binder and uses cellulose fiber, which is a natural material, the burden on the environment can be reduced. Moreover, by using the cellulose granule granulated substantially only with the cellulose fiber, it can be set as a highly safe cosmetic composition, and can give the user a sense of security.
＜セルロース繊維＞
　セルロース顆粒に含まれるセルロース繊維の原料としては、広葉樹や針葉樹由来の木材由来のパルプ、リンターなどの非木材由来のパルプなど特に限定されるものではないが、セルロース顆粒の造粒調整の簡便性から、木材由来のセルロース繊維を用いることが好ましいく、繊維径や繊維幅が針葉樹パルプよりも小さい広葉樹パルプを用いることが好ましい。 <Cellulose fiber>
The raw material of the cellulose fiber contained in the cellulose granule is not particularly limited, such as pulp derived from hardwood or coniferous wood, pulp derived from non-wood such as linter, but from the ease of adjusting the granulation of cellulose granules It is preferable to use cellulose fibers derived from wood, and it is preferable to use hardwood pulp having a fiber diameter and fiber width smaller than those of softwood pulp.
　また、本発明において、パルプ化法（蒸解法）は特に限定されるものではなく、サルファイト蒸解法、クラフト蒸解法、ソーダ・キノン蒸解法、オルガノソルブ蒸解法などを例示することができるが、これらの中では、環境面の点から、平均重合度が低くなる、サルファイト蒸解法が好ましい。 In the present invention, the pulping method (digestion method) is not particularly limited, and examples thereof include sulfite cooking method, kraft cooking method, soda-quinone cooking method, organosolv cooking method, etc. Of these, the sulfite cooking method is preferred because the average degree of polymerization is low from the environmental point of view.
　本発明に用いられるセルロース繊維は、塩酸、硫酸、硝酸などの鉱酸で酸加水分解処理したパルプを粉砕処理、あるいは酸加水分解処理を施さないパルプを機械粉砕して得ることができる。 The cellulose fiber used in the present invention can be obtained by pulverizing pulp hydrolyzed with a mineral acid such as hydrochloric acid, sulfuric acid or nitric acid, or mechanically pulverizing pulp not subjected to acid hydrolyzing.
　上記のパルプ原料を酸加水分解処理し機械粉砕してセルロース繊維を得る場合、原料パルプスラリー調製工程、酸加水分解反応工程、中和・洗浄・脱液工程、乾燥工程、粉砕工程、分級工程を経て製造される。 When cellulose fiber is obtained by acid hydrolysis treatment and mechanical pulverization of the above pulp raw materials, raw pulp slurry preparation process, acid hydrolysis reaction process, neutralization / washing / dehydration process, drying process, pulverization process, classification process It is manufactured after.
　パルプ原料は、流動状態でもシート状でも可能である。パルプ漂白工程からの流動パルプを原料とする場合は、加水分解反応槽へ投入する前に、濃度を高める必要があり、スクリュープレスやベルトフィルターなどの脱水機で濃縮され、反応槽へ所定量が投入される。パルプのドライシートを原料とする場合は、ロールクラッシャーなどの解砕機などでパルプをほぐした後、反応槽へ投入する。 The pulp raw material can be in a fluidized state or in a sheet form. When fluidized pulp from the pulp bleaching process is used as a raw material, it is necessary to increase the concentration before it is put into the hydrolysis reaction tank, and it is concentrated by a dehydrator such as a screw press or a belt filter. It is thrown. When a pulp dry sheet is used as a raw material, the pulp is loosened with a crusher such as a roll crusher and then put into a reaction vessel.
　次に、酸濃度０．１０～１．２Ｎに調整したパルプ濃度３～１０重量％（固形分換算）の分散液を、温度８０～１００℃、時間３０分間～３時間の条件で処理する。パルプの加水分解処理後、脱水工程で加水分解処理されたパルプと廃酸とに固液分離される。加水分解処理されたパルプはアルカリ剤を添加して中和し、洗浄される。その後、乾燥機で乾燥され、粉砕機で規定の大きさに機械的に粉砕・分級される。 Next, a dispersion having a pulp concentration of 3 to 10% by weight (converted to solid content) adjusted to an acid concentration of 0.10 to 1.2 N is treated under conditions of a temperature of 80 to 100 ° C. and a time of 30 minutes to 3 hours. After the hydrolysis of the pulp, solid-liquid separation is performed on the pulp hydrolyzed in the dehydration step and the waste acid. The hydrolyzed pulp is neutralized by adding an alkaline agent and washed. Then, it is dried with a dryer and mechanically pulverized and classified to a specified size with a pulverizer.
　粉砕の方式は特に限定されるものではなく、カッティング式ミル、ハンマー式ミル、衝撃式ミル、気流式ミル、竪型ローラーミルなど各種粉砕機を使用することができる。 The grinding method is not particularly limited, and various grinding machines such as a cutting mill, a hammer mill, an impact mill, an airflow mill, and a vertical roller mill can be used.
　本発明におけるセルロース繊維に、機能性付与、もしくは機能性向上を目的に、セルロース繊維の原料とその他有機および／または無機成分を単独もしくは２種類以上任意の割合で混合し、粉砕してもよい。また、原料に使用する天然セルロースの重合度を大幅に損なわない範囲で、化学的処理を施してもよい。 For the purpose of imparting functionality or improving functionality to the cellulose fiber in the present invention, the raw material of cellulose fiber and other organic and / or inorganic components may be mixed alone or in an arbitrary ratio of two or more, and pulverized. Moreover, you may give a chemical process in the range which does not impair the polymerization degree of the natural cellulose used for a raw material significantly.
　一方、酸加水分解処理を施していないパルプを原料から機械粉砕のみで粉体を製造することも可能である。 On the other hand, it is also possible to produce a powder from a raw material by merely mechanically crushing a pulp that has not been subjected to acid hydrolysis treatment.
　その様な方法により得られた本発明のセルロース繊維は、セルロース繊維の平均粒子径は、好ましくは５～５０μｍであり、より好ましくは５～４５μｍであり、さらに好ましくは５～４０μｍである。セルロース繊維の平均粒子径が上記下限未満であると、粒子が細かいためセルロース顆粒の造粒が困難となり、またセルロース繊維の平均粒子径が上記上限を超えても、粒子が大きいため造粒が困難となる。 In the cellulose fiber of the present invention obtained by such a method, the average particle diameter of the cellulose fiber is preferably 5 to 50 μm, more preferably 5 to 45 μm, and further preferably 5 to 40 μm. If the average particle diameter of the cellulose fiber is less than the above lower limit, it becomes difficult to granulate the cellulose granules because the particles are fine, and even if the average particle diameter of the cellulose fiber exceeds the upper limit, granulation is difficult because of the large particles.

　なお、本発明において用いられるセルロース顆粒を作成するために用いセルロース繊維は、市販入手も可能である。 In addition, the cellulose fiber used for preparing the cellulose granule used in the present invention is also commercially available.
＜セルロース顆粒の製造方法＞
　本発明において用いられるセルロース顆粒を得る方法としては、セルロース繊維を造粒し球形粒を作成できるものであればよく、乾式造粒法、湿式造粒法などの制限はなく、公知の造粒方法を用いることができる。造粒方法としては、例えば、圧片造粒法などの乾式造粒法；撹拌造粒、転動造粒法、転動流動造粒法、遠心転動造粒法、流動層造粒法、撹拌転動造粒法、噴霧乾燥造粒法、押出造粒法、溶融造粒法などの湿式造粒法を例示することができる。 <Method for producing cellulose granules>
As a method for obtaining the cellulose granules used in the present invention, any method can be used as long as it can granulate cellulose fibers to produce spherical particles, and there are no limitations on dry granulation methods, wet granulation methods, etc., and known granulation methods Can be used. Examples of the granulation method include dry granulation methods such as a pressure granulation method; stirring granulation, tumbling granulation method, tumbling fluidized granulation method, centrifugal tumbling granulation method, fluidized bed granulation method, Examples thereof include wet granulation methods such as stirring tumbling granulation method, spray drying granulation method, extrusion granulation method, and melt granulation method.
　湿式造粒法を用いてセルロース顆粒を製造する場合、造粒装置に仕込むセルロース繊維が飛散しないように予め水又は水を主成分とする液体を添加し湿潤にさせていることが好ましい。さらに、造粒装置内で、水又は水を主成分とする液体をセルロース繊維に噴霧させることが好ましい。水又は水を主成分とする液体とは、水単独または水とエタノールの混合溶液等を用いることができるが、硬度や密度に優れる造粒物を得るためには、水のみを用いることが好ましい。造粒乾燥時にはセルロース間に水素結合や分子間力などの相互作用が形成され造粒物を形成していくが、造粒後の乾燥が阻害されないバランス内において、添加・噴霧液中の水比率が高くなるほど、セルロース間の相互作用が促進され、密度や硬度に優れるセルロース顆粒となることができると推測される。 In the case of producing cellulose granules using a wet granulation method, it is preferable that water or a liquid containing water as a main component is added in advance so as to prevent the cellulose fibers charged in the granulator from scattering. Furthermore, it is preferable to spray the cellulose fiber with water or a liquid containing water as a main component in the granulator. As water or a liquid containing water as a main component, water alone or a mixed solution of water and ethanol can be used, but in order to obtain a granulated product having excellent hardness and density, it is preferable to use only water. . During granulation drying, interactions such as hydrogen bonds and intermolecular forces are formed between the cellulose to form a granulated product, but within a balance that does not inhibit drying after granulation, the water ratio in the added / sprayed liquid It is presumed that the higher the value, the more the interaction between the cellulose is promoted and the cellulose granules can be excellent in density and hardness.
　湿式造粒法における噴霧条件（噴霧量、時間、回数）は、回転数や、原料となるセルロース繊維の量などとの関係で異なり、一概に規定することは出来ないが、一例として、回転数を定めたのち、スリットエアー量と噴霧液とのバランスを適宜調整し定めることができる。 The spraying conditions (spraying amount, time, number of times) in the wet granulation method differ depending on the number of rotations and the amount of cellulose fibers used as a raw material, and cannot be specified unconditionally. For example, the number of rotations Then, the balance between the slit air amount and the spray liquid can be adjusted and determined as appropriate.
　なお、本発明において、平均粒子径は、造粒装置の造粒条件、造粒したセルロース顆粒に粉砕処理・分級処理を施すことによりコントロールすることが可能である。 In the present invention, the average particle size can be controlled by subjecting the granulation conditions of the granulator to pulverization / classification to the granulated cellulose granules.
