Description

【0001】
【発明の属する技術分野】
本発明は、油中水型乳化組成物に関し、更に詳細には、塗布時に清涼感を与え、塗布後は肌効果の持続や化粧持ち、滑らかな感触に優れ、乳化安定性にも優れた外用の油中水型乳化組成物に関する。
【0002】
【従来の技術】
粉体を含有する乳化化粧料には、ファンデーション、マスカラ、アイライナー等のメーキャップ化粧料や、パック、マッサージ、乳液、クリーム、クレンジング料等の基礎化粧料、日焼け止め料等があるが、乳化形態から分類すると、水中油型乳化化粧料と、油中水型乳化化粧料に分類できる。これらの乳化化粧料は水を含有するため、油性化粧料に比べて、肌に塗布した場合さっぱり感を付与し、さらに油性感は少ない。又、外観は液状やクリーム状のものが多く、肌上でののびが良く、ムラのない均一な仕上がりが得られやすい等の特性を有する。
特に油中水型乳化化粧料は、水中油型乳化化粧料に比べて油相が連続相であるため、皮膚表面上に水分透過性の低い油膜を残し、長時間にわたって肌を乾燥から保護すると共に、水と接触しても再乳化を起こすことが少なく、化粧崩れが起こりにくい。又、水溶性ビタミン類等の比較的不安定な水溶性薬剤や美容成分をより安定に保つ効果があり、皮膚上に塗布した際もその撥水性により塗布膜が長時間保持されるため、美容効果をより持続させることができる。
【0003】
【発明が解決しようとする課題】
しかしながら、従来の油中水型乳化化粧料は、安定化のために水分量を制限したり、又、粘性の高い油成分を使用したりすることが多く、べたつき感や油性感が強く感じられた。そして、べたつきが少なく、さっぱりした使用感を得るために、後述の一般式(2)、(3)又は(4)で示されるポリシロキサンを配合することが知られている。しかし、これらのポリシロキサンは、通常の界面活性剤や他の油分との相溶性が悪いという欠点があった。又、エチルアルコールを配合して清涼感を付与することも考えられるが、系の安定性を著しく低下させるという欠点があった。
従って、ポリシロキサン含有の系にさらにエチルアルコールを配合することは、非常に困難であった。つまり、油中水型乳化化粧料は水中油型化粧料に比較して優れているにもかかわらず、清涼感のなさ、べたつき感などの使用性から、多くは利用されていないのが現状である。
【0004】
本発明は、前記課題を解決するものとしてなされたものであり、その目的は、安定性が高く、しかも優れた清涼感を有し、美容効果の持続に優れ、塗布後もさっぱりとしていながら化粧持ちの良い油中水型乳化組成物を得ることにある。
【0005】
【課題を解決するための手段】
このような事情に鑑み、本発明者らは上記課題を解決すべく鋭意検討を行った結果、特定のポリエーテル変性シリコーンを乳化剤として用い、ポリシロキサン及び撥水処理粉体を含む油相中に一定濃度のエチルアルコールを含む水相を特定量加えることで、乳化が長時間安定となり、清涼感を付与し、べたつきがなく、塗布後は化粧崩れしにくく、美容効果の持続性にも優れた油中水型乳化組成物を得ることができることを見出した。

【0015】
【発明の実施の形態】
本発明に用いられる(A)成分のポリエーテル変性シリコーンは、前記一般式(1)で表されるものであり、分子中にポリオキシアルキレン基を5〜40重量%含有し、かつ、分子量が2000以上のものであって、その1種又は2種以上を任意に選択して用いることができる。
この(A)成分の配合量は、本発明の油中水型乳化組成物中、0.05〜10重量%(以下、重量%を単に「%」と示す)、好ましくは0.1〜5%である。(A)成分を10%を超えて配合しても効果が既に飽和に達しており意味がなく、0.05%未満では本発明の効果が弱く、特に長期安定性に乏しい。
この(A)成分のポリエーテル変性シリコーンは、前記一般式(5)で表されるものであるとより好ましい。
【0016】
本発明に用いられる(B)成分は、50%以上の前記一般式(2)、(3)又は(4)で表されるポリシロキサンと50%未満のそれ以外の油成分からなるものであるが、ポリシロキサンのうち好ましいものは一般式(2)、(4)のものであり、このうち特に(4)で表される環状のものが、揮発性を有し、油性感がなくさっぱりした感触を与えるので好ましい。又、(4)のポリシロキサンは、長期安定性にも優れる。これらの市販品としては、例えば、SH244、SH344、SH245、DC345(以上東レ・ダウコーニング・シリコーン社製)、KF994、KF995、KF996、KF9956(以上信越化学工業社製)、TSF404、TSF405、TSF406(以上東芝シリコーン社製)等が挙げられる。
(B)成分中、ポリシロキサン以外の油成分としては、例えば、流動パラフィン、スクワラン等の炭化水素、ミンク油、ホホバ油等の天然動植物油脂、ミリスチン酸イソプロピル、ミリスチン酸オクチルドデシル等の合成エステル油等が挙げられる。
(B)成分中のポリシロキサン量が50%未満の場合は、乳化粒子が粗大なものになり易く、長期安定性を保つことが難しい。(B)成分の配合量は、本発明の油中水型乳化組成物中、12〜60%であり、好ましくは14〜40%である。(B)成分の配合量が12%未満では乳化が良好でなく、60%を超えると、さっぱり感、清涼感が減じて好ましくない。
【0017】
本発明に用いられる(C)成分は、化粧料等に一般に用いられる公知の粉体を撥水処理したものであり、粉体としては、例えば、タルク、セリサイト、マイカ、カオリン、シリカ、酸化鉄、酸化チタン、酸化亜鉛、群青、紺青、酸化クロム等の無機粉体や、雲母チタン等のこれらの複合無機粉体、ナイロンパウダー、ポリエチレンパウダー等の有機粉体、有機タール系色素及びそのレーキ顔料等が挙げられ、撥水処理剤としては、例えば、高級脂肪酸、高級アルコール、脂肪酸エステル、金属石けん、アミノ酸、アルキルフォスフェート、フッ素化合物、シリコーン化合物等が挙げられる。本発明に用いられる(C)成分としては、これらの中でも、高級脂肪酸、デキストリン脂肪酸エステル、フッ素化合物、シリコーン化合物を用いて表面撥水処理した粉体がより好ましい。
なお、撥水処理しない粉体を使用した場合、油系中に分散することは困難であり、水系中に分散すると、使用中よれが生じやすく、塗布後は水や汗によって化粧崩れがおきやすい。
この(C)成分の配合量は、本発明の油中水型乳化組成物に0.1〜60%、好ましくは0.3〜30%である。(C)成分の配合量が0.1%未満では、使用後の肌にさっぱり感を与えたり、滑らかな感触にしたり、メイキャップ効果を付与したりすることができず、60%を超える場合は、粉っぽさが著しくなり、本発明の目的である清涼感が乏しくなる。
【0018】
本発明に用いられる(D)成分のエチルアルコール水溶液は、エチルアルコール:水の重量比が50:50〜2:98の範囲であり、特に、35:65〜5:95の範囲にあることが好ましい。エチルアルコール:水の重量比が2:98未満では、エチルアルコールによる清涼感が感じられなくなり、50:50を超えると、乳化が不安定となり、また皮膚への刺激が強くなる。
本発明の(D)成分の配合量は、本発明の油中水型乳化組成物に15〜80%、好ましくは30〜70%である。(D)成分の配合量が15%未満では、実際に使用したときの清涼感が乏しく、80%を超えると長期安定性が悪くなる。
なお、本発明の(D)成分には、必要に応じて、保湿剤や、各種のアミノ酸、消炎剤、殺菌剤、ビタミン類等の薬効成分等を配合することができる。
【0019】
本発明に用いられる(E)成分は、前記一般式(6)及び/又は(7)で表されるアルキルポリエーテル変性シリコーンであり、本発明の油中水型乳化組成物に炭化水素、高級脂肪酸エステル等の炭素骨格を有する油分を油成分中1%以上配合する場合にこの(E)成分を配合すると、更に良好な乳化安定性を保つことができる。この(E)成分のアルキルポリエーテル変性シリコーンは、市販品では、例えば、ABIL EM90(ゴールドシュミット社製)等が挙げられる。本発明の(E)成分の配合量は、本発明の油中水型乳化組成物に好ましくは0.05〜10%、より好ましくは0.1〜5%である。(E)成分の配合量が0.05%未満では、あまり効果がなく、10%を超えて配合しても効果が既に飽和に達しており意味がない。
【0020】
本発明の油中水型乳化組成物は、例えば以下のようにして調製できる。
(B)成分に(A)成分を添加して攪拌し、次いで(C)成分を添加、攪拌しながら(D)成分を少量づつ添加して本発明の油中水型乳化組成物を得る。本発明の油中水型乳化組成物には、さらに(E)成分を(A)成分と共に添加することができる。上記の方法において、調製温度は5〜90℃の任意の温度を用いることができる。
【0021】
本発明の油中水型乳化組成物は、粘度が低く室温下で液状のものから、クリーム状、更には固型状のものまで、各種の性状のものが含まれる。又、本発明の油中水型乳化組成物は、特に粘度が比較的低い場合、長時間静置した時に上部に油成分の層が多少分離する場合もあるが、軽い振盪により均一化することができる。
本発明の油中水型乳化組成物は、粉体を含み、清涼感のある化粧料であれば特に限定されず、ファンデーション、アイライナー、マスカラ、サンスクリーン料等が挙げられ、又、各種美容剤を配合して美容効果の持続が期待されるものとしては乳液、クリーム、パック、マッサージ料等が挙げられる。

The emulsified cosmetics containing powder include makeup cosmetics such as foundation, mascara, eyeliner, basic cosmetics such as packs, massages, emulsions, creams, cleansings, sunscreens, etc. Can be classified into oil-in-water emulsified cosmetics and water-in-oil emulsified cosmetics. Since these emulsified cosmetics contain water, they give a refreshing feeling when applied to the skin and are less oily than oily cosmetics. In addition, the appearance is often liquid or creamy, has good properties such as good spread on the skin and a uniform finish with no unevenness.
In particular, water-in-oil emulsified cosmetics have a continuous oil phase compared to oil-in-water emulsified cosmetics, and therefore leave an oil film with low moisture permeability on the skin surface to protect the skin from drying for a long time. At the same time, re-emulsification hardly occurs even when it comes in contact with water, and makeup collapse is unlikely to occur. It also has the effect of keeping relatively unstable water-soluble drugs such as water-soluble vitamins and cosmetic ingredients more stably, and even when applied on the skin, the coating film is held for a long time due to its water repellency, so beauty The effect can be further sustained.
[0003]
[Problems to be solved by the invention]
However, conventional water-in-oil emulsified cosmetics often limit the amount of water for stabilization, and often use highly viscous oil components, so that a sticky and oily feeling is strongly felt. It was. And in order to obtain a refreshing feeling of use with little stickiness, it is known to blend a polysiloxane represented by the following general formula (2), (3) or (4). However, these polysiloxanes have the disadvantage of poor compatibility with ordinary surfactants and other oils. In addition, it is conceivable to add ethyl alcohol to give a refreshing feeling, but there is a drawback that the stability of the system is remarkably lowered.
Therefore, it has been very difficult to further add ethyl alcohol to the polysiloxane-containing system. In other words, even though water-in-oil emulsified cosmetics are superior to oil-in-water cosmetics, they are not widely used because of their coolness and stickiness. is there.
[0004]
The present invention has been made to solve the above-mentioned problems, and its purpose is to provide makeup with a high stability and excellent refreshing feeling, excellent beauty effect, and refreshing after application. The object is to obtain a water-in-oil emulsion composition having good durability.
[0005]
[Means for Solving the Problems]
In view of such circumstances, as a result of intensive studies to solve the above problems, the present inventors have used a specific polyether-modified silicone as an emulsifier, and in an oil phase containing polysiloxane and water-repellent treated powder. By adding a certain amount of aqueous phase containing a certain concentration of ethyl alcohol, the emulsification becomes stable for a long time, gives a refreshing feeling, does not stickiness, is difficult to break the makeup after application, and has excellent sustainability of the cosmetic effect. It has been found that a water-in-oil emulsion composition can be obtained.

[0016]
The component (B) used in the present invention comprises 50% or more of the polysiloxane represented by the general formula (2), (3) or (4) and less than 50% of the other oil components. However, among the polysiloxanes, preferred are those of the general formulas (2) and (4), and among them, the cyclic one represented by (4) is particularly volatile and has no oiliness. It is preferable because it gives a touch. The polysiloxane (4) is also excellent in long-term stability. As these commercial products, for example, SH244, SH344, SH245, DC345 (more from Toray Dow Corning Silicone), KF994, KF995, KF996, KF9956 (more than Shin-Etsu Chemical Co., Ltd.), TSF404, TSF405, TSF406 ( As mentioned above, manufactured by Toshiba Silicone Co., Ltd.).
