【産業上の利用分野】
本発明は水中油型メーキャップ化粧料に係り、さらに詳しくは、通常の洗顔料で落としやすいにもかかわらず、耐水性、耐汗性、耐皮脂性、耐油性、使用性(なめらかさ)に優れ、化粧もちに優れたマスカラ、アイライナー、アイシャドウ、ファンデーション等の水中油型メーキャップ化粧料に関する。
【0002】
【従来の技術】
従来から用いられているマスカラ、アイライナー、アイシャドウ、ファンデーション等メーキャップ化粧料は、乳化タイプ、乳化皮膜タイプおよび油性タイプに大別することができる。
【0003】
乳化タイプは、固型、半固型、液状油分〜水系を主成分とする水中油型の基剤を乳化したものである。これは膜の均一性やのびといった使用性、乾燥性、安定性等に優れるという利点をもつ反面、水、汗、涙などで落ちやすく、特にアイライナー、マスカラ等においては、それらがにじみ、経時で目の周囲を汚しやすいという問題点がある。
【0004】
マスカラ等においてこの問題点を解決しようとしたのが、特開昭50−125043号公報等にみられるような、固型、半固型、液状油分〜水〜ポリマーエマルジョン系の乳化皮膜タイプのものである。しかしこのタイプのものも、ポリマーエマルジョンを加えることによって水の浸透を遅らせることは可能となったが、ポリマーエマルジョン自体の耐水性が配慮されていないために、水で落としやすいというメリットはあるものの、逆に耐水性は必ずしも完全なものではない。
【0005】
また油性タイプは、固型、半固型、液状油分〜揮発性分岐炭化水素系を主成分とするものである。これは耐水性、乾燥性は良好であるが、その組成が揮発性分岐炭化水素に固型パラフィン、ワックス、ラノリン誘導体などを溶解し、そこに各種顔料粉末を分散したものであるため、耐油性に劣るという欠点がある。そのため、特にマスカラ等の場合、塗布、乾燥後もまばたきなどにより瞼についている皮脂やファンデーション等の他の化粧品に含まれる油分に溶解し、顔料が塗布皮膜から欠け落ちて下瞼に付着(2次付着)し、目の周囲を汚しやすいという問題がある。また、化粧落としには専門の油性のリムーバーを用いる必要があり、洗浄にも著しい手間がかかるという欠点もある。
【0006】
【発明が解決しようとする課題】
本発明は上記事情に鑑みてなされたもので、その目的とするところは、通常の洗顔料で落としやすいにもかかわらず、耐水性、耐汗性、耐皮脂性、耐油性、使用性(なめらかさ)に優れ、化粧もちに優れたマスカラ、アイライナー、アイシャドウ、ファンデーション等の水中油型メーキャップ化粧料を提供することにある。
【0007】
【課題を解決するための手段】
本発明者らは、上記従来例の問題点を解決するために鋭意研究を行った結果、
▲1▼直接まつ毛や皮膚等に触れる外相部分を水相とし、ここにさらに水溶性高分子を配合することによって、使用性、安全性、安定性等に優れ、しかも雨や涙には強いにもかかわらず通常の洗顔料に対する落としやすさは良好であり、さらに油によるにじみを防止することができるということ、さらに▲2▼内相(油相)に揮発性油分と油溶性樹脂を配合することによって耐水性、特に耐にじみ性を著しく向上させることができるということ、等の知見を得、これらの知見に基づいて本発明を完成するに至った。
【0008】
すなわち本発明によれば、外相に水とポリビニルアルコールとを含有し、内相に沸点が60〜260℃の範囲にある炭化水素油およびシリコーン油の中から選ばれる1種または2種以上の揮発性成分と、下記の化1

【0011】
以下、本発明について詳述する。
【0012】
まず外相(水相)について説明する。本発明においては、外相に水および水溶性高分子としてポリビニルアルコールを必須構成成分として含む。
【0019】
ポリビニルアルコールは、皮膜形成能が高く、接着性の高い水溶性高分子で、その配合量は、化粧料全重量に対し0.01〜10重量%配合されるのが好ましく、通常の洗顔料での落としやすさをより向上させるという点からは0.1〜10重量%がより好ましく、さらには0.5〜10重量%が最も好ましい。
【0020】
なお、この外相にはさらに色材を配合することができる。色材としては、一般の化粧品に用いられる色材であれば何でもよい。ただし、後で説明するように、耐水性という点からは色材は疎水性の表面をもつものを内相(油相)中に配合するのがさらに好ましいが、これに限定されるものではない。
【0021】
また外相にはさらに、一般に化粧品に用いられるポリマーエマルジョン樹脂を適宜配合してもよい。このポリマーエマルジョン樹脂として、例えばアクリル酸エチル、メタクリル酸メチル、メタクリル酸ブチル、メタクリル酸、塩化ビニリデン等のモノマーと塩酸ビニルとの共重合エマルジョン等が挙げられる。
【0022】
上記以外にも、目的に応じて本発明の効果を損なわない量的、質的範囲内で、防腐剤、アルコール、多価アルコール、薬剤、界面活性剤、増粘剤、粘土鉱物、香料、酸化防止剤、紫外線吸収剤、保湿剤等を配合してもよい。

【0037】
なお、疎水化処理方法としては、撥水性を付与できる方法であればいかなるものでもよく、その方法は問わないが、例えば気相法、液相法、オートクレーブ法、メカノケミカル法等、通常の表面処理方法を用いることができる。
【0038】
例えば疎水化処理剤を原料粉末に添加して処理を行う場合、適当な溶媒(ジクロルメタン、クロロホルム、ヘキサン、エタノール、キシレン、揮発性シリコーン等)に希釈して添加してもよく、あるいは直接添加してもよい。粉末と処理剤の混合攪拌には、ボールミル、ホジャーサイトボールミル、振動ボールミル、アトライター、ポットミル、ロッドミル、パンミル、ホモミキサー、ホモディスパー、ヘンシェルミキサー、ナウターミキサー等も使用することができる。この他にも、粉末表面の活性を利用し、気相反応により100℃以下の低温で環状オルガノシロキサンを粉体表面上で重合させる方法(特公平1−54380号)や、前記方法の後に表面のシリコーンポリマーのSi−H部分にグリセロール、モノアリルエーテル等のペンダント基を付加させる方法(特公平1−54381号)等を用いることができる。

[Industrial applications]
The present invention relates to an oil-in-water make-up cosmetic, and more particularly, is excellent in water resistance, sweat resistance, sebum resistance, oil resistance, and usability (smoothness) despite being easy to remove with a normal face wash. The present invention relates to an oil-in-water makeup cosmetic such as mascara, eyeliner, eyeshadow, and foundation, which has excellent makeup.
[0002]
[Prior art]
Conventionally used makeup cosmetics such as mascara, eyeliner, eyeshadow and foundation can be broadly classified into emulsifying type, emulsifying film type and oily type.
[0003]
The emulsified type is obtained by emulsifying a solid, semi-solid, oil-in-water base mainly composed of a liquid oil-water system. This has the advantage of excellent usability such as uniformity and spreading of the film, drying property, stability, etc.On the other hand, it is easy to fall off with water, sweat, tears, etc., especially in eyeliner, mascara, etc. There is a problem that it is easy to stain around the eyes.
[0004]
In order to solve this problem in mascara and the like, an emulsified film type of a solid, semi-solid, liquid oil-water-polymer emulsion system as disclosed in JP-A-50-125043, etc. It is. However, this type can also delay the permeation of water by adding a polymer emulsion.However, although the water resistance of the polymer emulsion itself is not considered, there is an advantage that it can be easily dropped with water. Conversely, water resistance is not always perfect.
[0005]
The oily type is a solid type, semi-solid type, mainly containing a liquid oil component to a volatile branched hydrocarbon system. It has good water resistance and drying properties, but its composition is such that solid paraffin, wax, lanolin derivatives, etc. are dissolved in volatile branched hydrocarbons and various pigment powders are dispersed therein, so oil resistance is high. There is a disadvantage that it is inferior. Therefore, especially in the case of mascara, etc., even after application and drying, the eyelids dissolve in oil contained in sebum and other cosmetics such as foundation due to blinking, and the pigment is chipped from the coating film and adheres to the lower eyelid (secondary) Adhering) and easily stain the area around the eyes. In addition, it is necessary to use a special oily remover for removing makeup, and there is also a disadvantage that it takes a considerable amount of time to clean.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and the object thereof is to provide a water-resistant, sweat-resistant, sebum-resistant, oil-resistant, and easy-to-use (even though easy to remove with a normal face wash). An object of the present invention is to provide an oil-in-water makeup cosmetic such as mascara, eyeliner, eyeshadow, and foundation, which is excellent in cosmetic durability.
[0007]
[Means for Solving the Problems]
The present inventors have conducted intensive research to solve the problems of the above conventional example,
(1) The external phase that directly touches the eyelashes and skin, etc. is made into an aqueous phase, and by adding a water-soluble polymer to it, it is excellent in usability, safety, stability, etc., and is resistant to rain and tears Nevertheless, it is easy to remove from normal face wash, and it can prevent bleeding by oil. (2) A volatile oil component and an oil-soluble resin are blended in the internal phase (oil phase). This has led to the finding that the water resistance, particularly the bleeding resistance can be significantly improved, and the like, and the present invention has been completed based on these findings.
[0008]
That is, according to the present invention, containing water and polyvinyl alcohol in the external phase, boiling point internal phase one or more selected from among hydrocarbon oils and silicone oils in the range of sixty to two hundred and sixty ° C. Volatile components and the following chemical formula 1
Embedded image
(Wherein, R represents a hydrocarbon having 1 to 6 carbon atoms or a phenyl group; n represents a value of 1.0 to 1.8)
An oil-in-water makeup cosmetic comprising one or more oil-soluble resins selected from organic silicone resins, aromatic hydrocarbon resins and polyisoprene resins comprising units of the average formula represented by Provided.
According to the present invention, there is provided the oil-in-water makeup cosmetic further comprising a coloring material having a hydrophobic surface in the internal phase.
[0011]
Hereinafter, the present invention will be described in detail.
[0012]
First, the external phase (aqueous phase) will be described. In the present invention, the outer phase contains water and polyvinyl alcohol as a water-soluble polymer as essential components.
[0019]
Polyvinyl alcohol is a water-soluble polymer having high film-forming ability and high adhesiveness , and is preferably incorporated in an amount of 0.01 to 10% by weight based on the total weight of the cosmetic. From the viewpoint of further improving the ease of dropping, 0.1 to 10% by weight is more preferable, and 0.5 to 10% by weight is most preferable.
[0020]
It should be noted that a coloring material can be further added to this external phase. The coloring material may be any coloring material used in general cosmetics. However, as described later, from the viewpoint of water resistance, it is more preferable to mix a colorant having a hydrophobic surface in the internal phase (oil phase), but the present invention is not limited to this. .
[0021]
Further, a polymer emulsion resin generally used for cosmetics may be appropriately added to the outer phase.
