Description

【0001】
【発明の属する技術分野】
本発明は、液状化粧料の製造方法に関するものである。
【0002】
【従来の技術】
ここでいう液状化粧料とは、人間の皮膚に塗布し何らかの色(透明も含む)を付与するもので、液状のものとする。以下アイライナーを例にとって説明するがこれに限定するものではない。
【0003】
アイライナーは、目の周囲にラインを入れて目をくっきりさせたり、大きく見せたり等するものである。アイライナーは、鉛筆型、固形粉末型等の液状以外のものもあるが、細くくっきりと描くには液状が優れている。
液状のものは皮膜タイプと非皮膜タイプとがあり、アイライナーをおとすとき皮膜をはがすだけできれいにおちる皮膜タイプが多い。
【0004】
この皮膜タイプのものは、顔料、樹脂エマルジョン、分散剤が水と混合されたものである。
【0005】
また、最近では単に黒のようなものだけでなく、パール剤とよばれる光沢を付与する粉体を用いることがある。このようなものは、光の反射等からの理由である程度サイズが必要となる。
【0006】
【発明が解決しようとする課題】
しかしながら、従来の液状アイライナーでは、無機顔料や上記パール剤は比重が大きいため、経時的に沈降し均一でなくなる。塗布時に容器を振り均一化することもある程度は可能であるが、手間であり、完全ではない。
よって、沈降を防止し、分散安定性を図るため、粘度を高くすることが行われている。
しかし、粘度が大きくなると当然ながら塗布性が悪い。即ち、筆やペン等の器具で描きにくくなるのである。
【0007】
そのため、比較的低粘度で、且つ顔料の沈降がほとんどなく、分散のよい化粧料が待望されていた。
【0008】
【課題を解決するための手段】
以上のような状況に鑑み、本発明者は鋭意研究の結果本発明液状化粧料の製造方法を完成させたものであり、その特徴とするところは、水、硫酸バリウム及びリン酸ナトリウムを混合したスラリーを予め準備し、このスラリーと高分子及び顔料を混合するものであって、該硫酸バリウムは全体の5〜70重量%である点にある。
【0009】
本発明化粧料は、アイライナーに限らず、皮膚に塗布するもので顔料を使用するものはすべて含むものとする。例えば、口紅、美爪料、アイシャドウその他である。
【0010】
硫酸バリウム(BaSO)は、市販されているものでよく、特別なものである必要はない。この硫酸バリウムは、比較的大きな結晶からコロイド程度のものまで製造可能であるが、ここでは非常に小さい微粉末をいう。そのサイズは、0.01〜10.0μmであり、中でも0.1〜1.0μmが好適である。
【0011】
リン酸ナトリウムは、分散剤として使用するのであるが、通常のリン酸の塩よりは、ポリリン酸のナトリウム塩が好適である。例えば、ヘキサメタリン酸ナトリウム等である。このリン酸の量でpHを調整する。そして、最終化粧料としてpHを6〜7に調整するのが好適である。
【0012】
以上の硫酸バリウムとリン酸ナトリウムと水を混合してスラリー状にする。これを予め準備しておくことが本発明の第1のポイントである。
【0013】
本発明でいう高分子は、通常は樹脂であり、アクリル系樹脂やポリビニルアルコール等が好適である。エマルジョンの状態でもよい。
また、顔料は一般の顔料だけでなく、ここではパール粉やガラスフレーク粉等のパール剤とよばれるものも含む。これらの顔料のサイズは、通常1〜100μmである。特に、ガラスフレークのような鱗片状のものでは、厚みは薄いが大きさはやはり数十μm程度のものである。
この顔料サイズと比較して、非常に小さいサイズの硫酸バリウムを用いるのがポイントである。
即ち、前記した通り、予めスラリーを作成し、それと樹脂や顔料を混合すると、サイズの大きな顔料の間に小さな硫酸バリウムが入り込み、非常に均一な分散となるばかりか、これが非常に長期間維持されるのである。
【0014】
また、単にサイズの小さい粉体ではなく、硫酸バリウムを用いているのは、硫酸バリウムがアクリル樹脂等と屈折率が近く、混合した時の透明性がよいためである。
【0015】
次に、これらの混合比率について説明する。
まず、スラリーであるが、これは硫酸バリウム100重量部に対して、水が10〜200重量部、リン酸ナトリウムが0.5〜10重量部が好適である。特に、水は30〜100重量部がよく、リン酸ナトリウムは1〜5重量部がよかった。
【0016】
このスラリー中の硫酸バリウムと、高分子や顔料との混合比率は、硫酸バリウム100重量部に対して、高分子(固形分換算)が10〜200重量部、顔料は0.1〜100重量部が好適である。
また、この時に更に水を加えてもよい。
【0017】
以上の成分以外にも、通常化粧料に混合される成分を添加してもよい。例えば、紫外線吸収剤、褪色防止剤、香料、防腐剤等である。
【0018】
本発明化粧の使用方法は、特に限定するものではなく、筆等で塗布するようにする、化粧料内蔵タイプのペン型塗布具に充填する等自由である。
【0019】

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for producing a liquid cosmetic.
[0002]
[Prior art]
The liquid cosmetic referred to here is applied to human skin to give some color (including transparency) and is liquid. Hereinafter, the eyeliner will be described as an example, but the present invention is not limited thereto.
[0003]
The eyeliner puts a line around the eye to make the eye clearer or to make it look larger. The eyeliner may be other than liquid such as a pencil type or a solid powder type, but the liquid is excellent for drawing finely and clearly.
There are two types of liquid types: film type and non-film type, and many film types can be cleaned simply by removing the film when the eyeliner is applied.
[0004]
In this film type, a pigment, a resin emulsion, and a dispersant are mixed with water.
[0005]
In addition, recently, not only a black material but also a powder imparting gloss called a pearl agent is sometimes used. Such a thing needs a certain size for reasons such as reflection of light.
[0006]
[Problems to be solved by the invention]
However, in the conventional liquid eyeliner, since the specific gravity of the inorganic pigment and the pearl agent is large, it settles with time and becomes non-uniform. It is possible to shake the container at the time of application to make it uniform, but it is troublesome and not perfect.
Therefore, in order to prevent sedimentation and improve dispersion stability, the viscosity is increased.
However, when the viscosity increases, the coating property is naturally poor. That is, it becomes difficult to draw with a tool such as a brush or a pen.
[0007]
Therefore, there has been a demand for cosmetics having a relatively low viscosity and almost no sedimentation of pigments and good dispersion.
[0008]
[Means for Solving the Problems]
In view of the above situation, the present inventor has completed the method for producing the liquid cosmetic composition of the present invention as a result of earnest research, and its feature is that water, barium sulfate and sodium phosphate are mixed. A slurry is prepared in advance, and the slurry, polymer and pigment are mixed, and the barium sulfate is 5 to 70% by weight of the whole.
[0009]
The cosmetic of the present invention is not limited to an eyeliner, but includes any that is applied to the skin and that uses a pigment. For example, lipstick, nail polish, eye shadow and others.
[0010]
Barium sulfate (BaSO 4 ) may be commercially available and need not be special. This barium sulfate can be produced from a relatively large crystal to a colloidal one, but here it refers to a very small fine powder. The size is 0.01-10.0 micrometers, and 0.1-1.0 micrometer is suitable especially.
[0011]
Sodium phosphate is used as a dispersant, but a sodium salt of polyphosphoric acid is preferable to a normal salt of phosphoric acid. For example, sodium hexametaphosphate. The pH is adjusted with the amount of phosphoric acid. And it is suitable to adjust pH to 6-7 as final cosmetics.
[0012]
The above barium sulfate, sodium phosphate and water are mixed to form a slurry. Preparing this in advance is the first point of the present invention.
[0013]
The polymer referred to in the present invention is usually a resin, and an acrylic resin, polyvinyl alcohol, or the like is preferable. It may be in an emulsion state.
The pigment includes not only a general pigment but also a so-called pearl agent such as pearl powder or glass flake powder. The size of these pigments is usually 1 to 100 μm. In particular, a scaly material such as glass flakes has a small thickness but a size of several tens of μm.
The point is to use barium sulfate having a very small size compared to the pigment size.
That is, as described above, when a slurry is prepared in advance and mixed with a resin or pigment, small barium sulfate enters between large pigments, resulting in a very uniform dispersion, and this is maintained for a very long time. It is.
[0014]
Further, the reason why barium sulfate is used instead of a powder having a small size is that barium sulfate has a refractive index close to that of an acrylic resin or the like and has good transparency when mixed.
[0015]
Next, these mixing ratios will be described.
First, the slurry is preferably 10 to 200 parts by weight of water and 0.5 to 10 parts by weight of sodium phosphate with respect to 100 parts by weight of barium sulfate. In particular, 30 to 100 parts by weight of water was good, and 1 to 5 parts by weight of sodium phosphate was good.
[0016]
The mixing ratio of barium sulfate in this slurry to the polymer or pigment is 10 to 200 parts by weight of polymer (in terms of solid content) and 100 to 100 parts by weight of pigment with respect to 100 parts by weight of barium sulfate. Is preferred.
At this time, water may be further added.
[0017]
In addition to the above components, components that are usually mixed in cosmetics may be added. For example, ultraviolet absorbers, anti-fading agents, fragrances, preservatives and the like.
[0018]
The method of using the makeup of the present invention is not particularly limited, and can be freely applied such as applying with a brush or the like and filling a cosmetic-embedded pen-type applicator.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings.
Example 1
(1) Water 100 parts by weight (2) Barium sulfate (particle size, average 1.0 μm) 100 parts by weight (3) Sodium phosphate (sodium hexametaphosphate) 2 parts by weight The three components are mixed well to form a slurry.
For 100 parts by weight of this slurry,
100 parts by weight of acrylic emulsion (solid content 50 parts by weight)
10 parts by weight of glass flakes were mixed to prepare a cosmetic. The pH was 6.5.
Example 2
(1) Water 70 parts by weight (2) Barium sulfate (particle size, average 1.0 μm) 100 parts by weight (3) Sodium phosphate (sodium hexametaphosphate) 2 parts by weight The three components are mixed well to form a slurry.
For 100 parts by weight of this slurry,
100 parts by weight of an acrylic emulsion and 5 parts by weight of a red pigment (Bengara) were mixed to prepare a cosmetic. The pH was 7.0.
[0020]
Comparative Example 1
(1) 100 parts by weight of water (2) 2 parts by weight of sodium phosphate (sodium hexametaphosphate) (3) 100 parts by weight of acrylic emulsion (4) 10 parts by weight of glass flakes were mixed to prepare a cosmetic.
[0021]
The three were mixed well and allowed to stand for 24 hours. Examples 1 and 2 were divided into a lower slurry portion and an upper emulsion portion. However, the pigment was uniformly dispersed in the lower slurry portion. When this was shaken as a whole, the whole was uniformly dispersed.
However, in the comparative example, the glass flakes settled downward (bottom) to form an agglomerated layer, and even when shaken, they were not uniformly dispersed.
[0022]
【The invention's effect】
The cosmetic of the present invention has the following great advantages.
(1) Despite the mixing of a large pigment, there was almost no sedimentation of the pigment, and a uniform dispersion could be maintained for a long time.
(2) Especially when used in pen-type applicators, there is no clogging and smooth application is always possible.
(3) Since barium sulfate is used, it is transparent and glossy.
