Description
本発明は、新規なデキストリン脂肪酸エステルを配合する固形粉末化粧料に関するものであり、更に詳しくは、成形性に優れ、使用時の伸び広がりが良好であり、化粧膜が均一で、化粧持続性が良好な固形粉末化粧料に関するものである。 The present invention relates to a solid powder cosmetic containing a novel dextrin fatty acid ester. More specifically, the present invention relates to a solid powder cosmetic, more excellent in moldability, good elongation spread during use, uniform cosmetic film, and makeup durability. It relates to a good solid powder cosmetic.
パウダーファンデーションやアイカラー等の固形粉末化粧料は、粉体成分に油性成分を添加混合した化粧料基材を、皿等の容器に充填成型してなる化粧料であり、使用方法が簡便な上に携帯性にも優れるため、消費者に好まれている。このため、固形粉末化粧料の開発においては様々な工夫がなされており、成型性に関しては、薄片状粉体や球状粉体を多量に配合しても成型性の良い方法として、湿式成型法（化粧料基剤に溶剤を過剰に添加し、スラリー状として容器に充填した後、過剰の溶剤を揮発や吸引により除去する方法）が提案されている（特許文献１、２）。
一方、デキストリン脂肪酸エステルは油ゲル化剤として知られており、固形粉末化粧料においても、使用感や安定性を向上させるために用いられている（特許文献３）。
Solid powder cosmetics such as powder foundation and eye color are cosmetics that are made by filling and molding a cosmetic base material in which an oily component is added to a powder component in a container such as a dish. It is also preferred by consumers because of its excellent portability. For this reason, various devices have been devised in the development of solid powder cosmetics. Regarding moldability, a wet molding method (as a method having good moldability even if a large amount of flaky powder or spherical powder is blended) There has been proposed a method in which an excess solvent is added to a cosmetic base, and the container is filled in a slurry and then the excess solvent is removed by volatilization or suction (Patent Documents 1 and 2).
On the other hand, dextrin fatty acid esters are known as oil gelling agents, and are also used in solid powder cosmetics to improve the feeling of use and stability (Patent Document 3).
しかしながら、特許文献１、２のような湿式成型法には、過剰の溶剤を除去する際に、成形品の表面にひびを生じやすいという問題があり、また、粒径の大きな真珠光沢顔料等を多量に配合すると、肌上での伸び広がりを悪化させ化粧持続性が悪くなる場合があった。特許文献３の化粧料においても、使用感の向上はみられるものの、化粧持続性は十分なものではなかった。このため、湿式成型法による成形が容易で、塗布時の伸び広がりと化粧膜の均一性が良好で、さらに化粧持続性にも優れる固形粉末化粧料の開発が求められていた。 However, the wet molding methods such as Patent Documents 1 and 2 have a problem that when the excess solvent is removed, there is a problem that the surface of the molded product is liable to be cracked. When blended in a large amount, the spread of spread on the skin may be worsened and makeup sustainability may be worsened. Even in the cosmetics of Patent Document 3, although the feeling of use is improved, the makeup sustainability is not sufficient. For this reason, there has been a demand for the development of a solid powder cosmetic that can be easily molded by a wet molding method, has a good spread and uniformity of the coating film, and has excellent makeup sustainability.
上記実状に鑑み、本発明者は鋭意研究を行った結果、湿式成型法において、新規なデキストリン脂肪酸エステルと、不揮発性油剤と、粉体とを配合する固形粉末化粧料を得ることにより、新規なデキストリン脂肪酸エステルの持つ柔軟な皮膜性能が発揮され、上記課題を解決する固形粉末化粧料が得られることを見出し、本発明を完成させた。 In view of the above situation, as a result of intensive studies, the present inventor has obtained a novel solid powder cosmetic comprising a novel dextrin fatty acid ester, a non-volatile oil agent, and powder in a wet molding method. The present inventors have found that solid film cosmetics that solve the above-mentioned problems can be obtained by exhibiting the flexible film performance possessed by dextrin fatty acid esters, and have completed the present invention.
すなわち、本発明は、
（１）粉体成分と油性成分とを含む化粧料基材に、揮発性溶剤を添加してスラリー状とし、これを容器又は中皿に充填した後、該揮発性溶剤を除去することにより成型される化粧料において、該化粧料基材中に、次の成分（ａ）〜（ｃ）；

以下、本発明を詳細に説明する。
本発明の固形粉末化粧料に使用される成分（ａ）のデキストリンと脂肪酸エステルは、デキストリンと脂肪酸とのエステル化物であり、デキストリンへの脂肪酸の置換度は、グルコース単位当たり１．０〜３．０であり、好ましくは１．２〜２．８である。この置換度が１．０未満であると液状油等への溶解温度が１００℃以上と高くなり、着色や特異な臭いが生じ、好ましくない。
Hereinafter, the present invention will be described in detail.
The dextrin and fatty acid ester of component (a) used in the solid powder cosmetic of the present invention is an esterified product of dextrin and fatty acid, and the degree of substitution of fatty acid for dextrin is 1.0 to 3 per glucose unit. 0, preferably 1.2 to 2.8. When the degree of substitution is less than 1.0, the dissolution temperature in liquid oil or the like is as high as 100 ° C. or higher, and coloring or a specific odor is not preferable.
また、成分（ａ）のデキストリン脂肪酸エステルは、次の特性を有する。
（１）液状油に混合したときに液状油がゲル化しない。
「液状油がゲル化しない」とは、ＡＳＴＭ Ｄ４４５測定方法による４０℃における動粘度が８ｍｍ２／ｓである流動パラフィンを液状油とする場合、デキストリン脂肪酸エステルを５質量％含有する該流動パラフィンを１００℃で溶解し、２４時間後２５℃で粘度を測定したとき、粘度が、Ｙａｍｃｏ ＤＩＧＩＴＡＬ ＶＩＳＣＯＭＡＴＥ粘度計ＶＭ−１００Ａ（振動式）（山一電機社製）の検出限界以下であることを意味する。なお、ゲル化する場合には、粘度が検出されることで確認できる。
The dextrin fatty acid ester of component (a) has the following characteristics.
(1) Liquid oil does not gel when mixed with liquid oil.
“Liquid oil does not gel” means that when liquid paraffin having a kinematic viscosity at 40 ° C. of 8 mm 2 / s according to ASTM D445 measurement method is used as liquid oil, the liquid paraffin containing 5% by mass of dextrin fatty acid ester is used. When dissolved at 100 ° C. and measured for viscosity after 24 hours at 25 ° C., it means that the viscosity is below the detection limit of the Yamaco DIGITAL VISCOMATE viscometer VM-100A (vibration type) (manufactured by Yamaichi Electronics Co., Ltd.) . In addition, when gelatinizing, it can confirm by detecting a viscosity.
（２）成分（ａ）のデキストリン脂肪酸エステルが形成する皮膜が特定範囲のタック性を有する。
「タック性」を、支持体に該デキストリン脂肪酸エステルを塗布し、もうひとつの支持体を相互に離れた状態から面接触させた後に、後退させて別離させ、後退を開始してから完全に別離するまでの接触点にかかる荷重変化（最大応力値）で表す場合、該デキストリン脂肪酸エステルを４０質量％含有する軽質流動イソパラフィン溶液をガラス板に４００μｍ厚のアプリケーターで成膜し、乾燥させた皮膜に、テクスチャーアナライザー、たとえば、テクスチャーアナライザーＴＡ．ＸＴｐｌｕｓ（Ｓｔａｂｌｅ Ｍｉｃｒｏ Ｓｙｓｔｅｍｓ社製）を用いて、プローブとして直径１２．５ｍｍ円柱状のポリアセタール樹脂（Ｄｅｌｒｉｎ（登録商標）デュポン社製）製プローブを使用し、１００ｇの荷重をかけ１０秒保持後に０．５ｍｍ／秒で離したときの荷重変化、すなわちタック性が３０〜１，０００ｇである。
(2) The film formed by the dextrin fatty acid ester of component (a) has a specific range of tackiness.
The “tackiness” is determined by applying the dextrin fatty acid ester to a support and bringing the other support into surface contact from a state where they are separated from each other, then retracting them and separating them. When expressed by the load change (maximum stress value) applied to the contact point until the film is formed, a light liquid isoparaffin solution containing 40% by mass of the dextrin fatty acid ester is formed on a glass plate with a 400 μm-thick applicator and dried. , Texture analyzers, eg texture analyzer TA. Using XTplus (manufactured by Stable Micro Systems), a probe made of a 12.5 mm diameter cylindrical polyacetal resin (manufactured by Delrin (registered trademark) DuPont) was used as a probe, and a load of 100 g was applied after 10 seconds. The load change when separated at 5 mm / second, that is, the tackiness is 30 to 1,000 g.
成分（ａ）のデキストリン脂肪酸エステルに用いられるデキストリンは、グルコース平均重合度３〜１５０、特に１０〜１００のデキストリンが好ましい。グルコース平均重合度が２以下では、得られたデキストリン脂肪酸エステルがワックス様となって油剤への溶解性が低下する。また、グルコース平均重合度が１５０を超えると、デキストリン脂肪酸エステルの油剤への溶解温度が高くなる、又は溶解性が悪くなる等の問題を生ずることがある。デキストリンの糖鎖は直鎖状、分岐鎖状、環状のいずれでもよい。 The dextrin used in the dextrin fatty acid ester of component (a) is preferably a dextrin having a glucose average polymerization degree of 3 to 150, particularly 10 to 100. When the average degree of polymerization of glucose is 2 or less, the obtained dextrin fatty acid ester becomes wax-like and the solubility in an oil agent decreases. On the other hand, when the average degree of polymerization of glucose exceeds 150, there may be a problem that the temperature for dissolving the dextrin fatty acid ester in the oil becomes high or the solubility becomes poor. The sugar chain of dextrin may be linear, branched or cyclic.
成分（ａ）のデキストリン脂肪酸エステルに用いられる脂肪酸は、炭素数４〜２６の分岐飽和脂肪酸の１種又は２種以上を必須とし、さらに炭素数２〜２２の直鎖飽和脂肪酸、炭素数６〜３０の直鎖又は分岐の不飽和脂肪酸、及び炭素数６〜３０の環状の飽和又は不飽和脂肪酸よりなる群から選ばれる１種又は２種以上（以下、これら炭素数４〜２６の分岐飽和脂肪酸以外の脂肪酸をまとめて表すときは「その他の脂肪酸」という）を含有してもよいものである。 The fatty acid used in the dextrin fatty acid ester of component (a) is essentially one or more of branched saturated fatty acids having 4 to 26 carbon atoms, and further is a linear saturated fatty acid having 2 to 22 carbon atoms, 6 to 6 carbon atoms. One or more selected from the group consisting of 30 linear or branched unsaturated fatty acids and cyclic saturated or unsaturated fatty acids having 6 to 30 carbon atoms (hereinafter these branched saturated fatty acids having 4 to 26 carbon atoms) When other fatty acids are expressed together, they may be referred to as “other fatty acids”.
脂肪酸の組成割合は、全脂肪酸に対して、炭素数４〜２６の分岐飽和脂肪酸の１種又は２種以上が５０ｍｏｌ％より多く１００ｍｏｌ％以下、好ましくは５５ｍｏｌ％以上１００ｍｏｌ％以下であり、その他の脂肪酸は、０ｍｏｌ％以上５０ｍｏｌ％未満、好ましくは、０ｍｏｌ％以上４５ｍｏｌ％以下である。
炭素数４〜２６の分岐飽和脂肪酸としては、例えば、イソ酪酸、イソ吉草酸、２−エチル酪酸、エチルメチル酢酸、イソヘプタン酸、２−エチルヘキサン酸、イソノナン酸、イソデカン酸、イソトリデカン酸、イソミリスチン酸、イソパルミチン酸、イソステアリン酸、イソアラキン酸、イソヘキサコサン酸等が挙げられ、これらの１種又は２種以上を適宜選択又は組み合わせて使用することができる。これらのうち、炭素数１２〜２２のものが好ましく、特にイソステアリン酸が好ましく、構造の違い等の限定は特にない。
