Description
本発明は、皮膚外用剤に関し、更に詳細には、粉体含有の乳化化粧料に好適な皮膚外用剤に関する。 The present invention relates to a skin external preparation, and more particularly, to a skin external preparation suitable for powder-containing emulsified cosmetics.
化粧料などの皮膚外用剤において、乳化剤形を適用することは、油溶性成分と、水溶性成分の両方を同一製剤に製剤化出来る点で非常に有用であり、特に、化粧料のように有効成分を多種含有する商品では、この有用性は非常に大きなものとなる。又、乳化剤形は通常安定な水−油界面を有するので、この界面を利用して、二酸化チタン、酸化亜鉛、酸化鉄、マイカ、チタンマイカ、タルクなどの無機系の粉体成分を安定に分散する分散媒にも使用される。特に、無機系の粉体類は金属酸化物を主成分とするため、油性成分のみ、或いは、水性成分のみの系では、その比重の大きさ故に、容易に沈降してしまうが、界面に配位することにより、安定に分散状態を保つことが出来る。又、その様な要件、即ち、しっかりとした界面構造を形成する剤形でなければ粉体含有の乳化製剤の剤形として適さないとも言える。この様な界面構造は、従来の技術においては、脂肪酸石鹸と高級アルコールによって形成される構造や、有機変性ヘクトライトと多価アルコールと水によって形成される網目構造が利用されてきた。その反面、この様な界面の形成には相間の相互作用が伴い、且つ、粉体と油相、或いは粉体と水相の相互間力が新たに生じるため、前記の安定な粉体分散乳化剤形における粘度は非常に高いものになり、剪断応力でも容易に壊れない構造を取りやすい。この為、高粘度を呈するようになり、使用性の面では、構造が崩れにくく、のびが重くなる傾向にあった。特に、無機系の粉体を５質量％以上含有する、高粉体含有の乳化組成物では、粉体同士の相互作用も加わり、チキソトロピー性を有する粘流動体を形成しやすい。この様な状況になると、のびの重さなどの使用性の欠如は更に著しくなる。即ち、無機系の粉体を含有する乳化剤形の皮膚外用剤において、実測の粘度が低く、それにより、のびなどの使用性も向上した製剤の開発が望まれていた。 In skin external preparations such as cosmetics, it is very useful to apply an emulsifier form in that both oil-soluble ingredients and water-soluble ingredients can be formulated into the same formulation. For commercial products containing various ingredients, this utility is very large. Moreover, the emulsifier type usually stable water - because it has a oil interface, the interface by using a titanium dioxide, zinc oxide, stably dispersed iron oxide, mica, titanium mica, the powder component of the inorganic such as talc It is also used as a dispersion medium. In particular, since inorganic powders are mainly composed of metal oxides, in the case of only oily components or only water-based components, they settle easily due to their large specific gravity, but are distributed at the interface. The dispersion state can be stably maintained by positioning. Further, it can be said that such requirements, i.e., also not suitable as dosage form for solid emulsified formulations unless powder containing formation to a dosage form interfacial structure. In such conventional interface structures, a structure formed by fatty acid soap and higher alcohol and a network structure formed by organically modified hectorite, polyhydric alcohol and water have been used in the prior art. A reaction surface, the interaction between the phases is accompanied to the formation of such surfactants, and, powder and oil phase, or powder and for mutual force of the aqueous phase newly generated, the stable powder dispersion The viscosity in the emulsifier form becomes very high, and it tends to take a structure that does not break easily even under shear stress. For this reason, high viscosity comes to be exhibited, and in terms of usability, the structure is less likely to collapse and the elongation tends to be heavy. In particular, containing a powder of inorganic least 5 wt%, the emulsion composition containing Kokonatai, interaction of the powder each other also added, tends to form a viscous fluid having thixotropic properties. In such a situation, the lack of usability such as the weight of the spread becomes more serious. That is, in the emulsifier- type skin external preparation containing an inorganic powder, it has been desired to develop a preparation having a low measured viscosity, thereby improving usability such as spreading.
前記の高級アルコール・脂肪酸石鹸構造や有機変性ヘクトライト・多価アルコール・水構造に代わる新規の乳化構造系としては、無機系の粉体の含有量の少ない乳化剤形においては、ステアロイル乳酸とアシル化ポリグリセリンの作る乳化系が粉体分散性と、その安定性に優れる系を創出することが知られている（例えば、特許文献１を参照）。しかしながら、この様な系に於いても、無機系の粉体量が多くなると、均一分散性が損なわれることが本発明者により見いだされている。 As a new emulsification structure system to replace the higher alcohol / fatty acid soap structure and organic modified hectorite / polyhydric alcohol / water structure, stearyl lactic acid and acylation are used in the emulsifier form with a small content of inorganic powder. It is known that an emulsifying system made of polyglycerin creates a system having excellent powder dispersibility and stability (see, for example, Patent Document 1). However, even in such a system, the present inventors have found that uniform dispersion is impaired when the amount of inorganic powder increases.
一方、ステアロイル乳酸等のアシル乳酸とアシル化ポリグリセリンの乳化構造系については、安定な水中油乳化系を作ることが知られている（例えば、特許文献２、特許文献３、特許文献４、特許文献５、特許文献６、特許文献７、特許文献８を参照）し、アシル乳酸とアニオン界面活性剤とを組み合わせて乳化する技術もすでに知られている（例えば、
特許文献９）が、アシル乳酸とアシル化ポリグリセリンと硫酸系アニオン界面活性剤との組み合わせは知られていないし、無機系の粉体との組み合わせも特許文献１以外は知られていない。
On the other hand, it is known to produce a stable oil-in-water emulsion system for an emulsion structure system of acyl lactic acid such as stearoyl lactic acid and acylated polyglycerin (for example, Patent Document 2, Patent Document 3, Patent Document 4, Patent Document 5, Patent Document 6, Patent Document 7, and Patent Document 8), and a technique for emulsifying a combination of acyllactic acid and an anionic surfactant is already known (for example,
In Patent Document 9), a combination of acyl lactic acid, acylated polyglycerin, and a sulfate-based anionic surfactant is not known, and a combination with an inorganic powder is not known except for Patent Document 1.
本発明は、この様な状況下為されたものであり、無機系の粉体を５質量％以上含有しながら、粘度が低く、以て、使用性に優れる乳化剤形の皮膚外用剤を提供することを課題とする。 The present invention has been made under such circumstances, and provides an emulsifier-type skin external preparation having a low viscosity and excellent usability while containing 5% by mass or more of an inorganic powder. This is the issue.
この様な状況に鑑みて、本発明者らは、無機系の粉体を５質量％以上含有しながら、粘度が低く、以て、使用性に優れる乳化剤形の皮膚外用剤を求めて、鋭意研究努力を重ねた結果、表面を親油化処理されていても良い、無機系の粉体を５〜３０質量％含有する、水中油乳化剤形の皮膚外用剤において、１）アシル乳酸及び／又はその塩０．０５〜５質量％と、２）アシル化ポリグリセリン０．１〜１０質量％と、３）硫酸系アニオン界面活性剤０．０１〜１質量％とを含有する、水中油乳化剤形の皮膚外用剤がその様な特性を有していることを見いだし、発明を完成させるに至った。即ち、本発明は以下に示すとおりである。

(4) Sulfate-based anionic surfactant that is an essential component of the skin external preparation of the present invention The skin external preparation of the present invention is characterized by containing a sulfate-based anionic surfactant as an essential component. Suitable examples of the sulfuric anionic surfactant include alkyl sulfates such as lauryl sulfate, sulfosuccinate salts such as sodium lauryl sulfosuccinate, and fatty acid glyceryl sulfate salts such as sodium cocoglyceryl sulfate. Fatty acid glyceryl sulfate salt is particularly preferable. As the fatty acid residue (acyl group) constituting the fatty acid glycerin sulfate ester salt, those having 10 to 30 carbon atoms are preferred, for example, lauroyl group, myristoyl group, palmitoyl group, stearoyl group, isostearoyl group, behenoyl group, An oleoyl group and the like can be suitably exemplified, and coconut oil fatty acid residues, beef tallow fatty acid residues, palm oil fatty acid residues and the like which are natural mixtures thereof can also be used. Of these, coconut oil fatty acid glyceryl sulfate is most preferable. These salts can be used without any particular limitation as long as they are used in skin external preparations, for example, alkali metal salts such as sodium salts and potassium salts, alkaline earth metal salts such as calcium salts and magnesium salts. Preferred examples include organic amine salts such as ammonium salt, triethylamine salt, triethanolamine salt, and monoethanolamine salt, and basic amino acid salts such as lysine salt and alginate. Particularly preferred salts are alkali metal salts, especially sodium salts. Such components have the effect of improving the dispersibility of the inorganic powder , which may be oleophilic, in the system, and reducing the thixotropy. In order to achieve such an effect, one or more selected from the above-mentioned sulfuric acid anionic surfactants are 0.01 to 1% by mass, more preferably 0.05 to 0.5% by mass. %. This is because if the amount is too small, the above-described effect may not be achieved, and if the amount is too large, the stability of the system may be impaired.
