Abstract
Description
本発明は乳化化粧料に関し、詳細には、透明〜半透明で審美性および使いやすさに優れ、肌への保湿感、浸透感が良く、塗布後の肌にべたつきがなく、肌のかさつきを改善し肌をなめらかにする、乳化化粧料単独においても、不織布に含侵させた状態であっても経時安定性が良好な乳化化粧料に関するものである。 The present invention relates to an emulsified cosmetic, and in particular, it is transparent to translucent, has excellent aesthetics and usability, has a good moisturizing feel on the skin, has a good feeling of penetration, has no stickiness on the skin after application, and has a smooth texture on the skin. The present invention relates to an emulsified cosmetic that improves and smoothes the skin and has good stability over time even when it is impregnated with a non-woven fabric.
近年、化粧料分野においてナノエマルジョン技術を利用した化粧料の提案が増えている（ナノエマルジョンとは、油性成分を水性成分中に、界面活性剤によって粒子径１００ｎｍ以下の状態に乳化している製剤のことと本明細書では定義する）。 一般にナノエマルジョンは非常に微細な油滴を形成していることにより、その外観は微青色透明〜微青色半透明となっており、またその塗布感は、乳液やクリームと比べて油性成分のべたつきが抑えられているにもかかわらず、保湿感・浸透感がよいという特徴を有する。 ナノエマルジョンの例として、リン酸脂肪エステル及びそれらのオキシエチレン化誘導体から選択されたアニオン性活性剤と、分子量４００以上の油性成分を含み、界面活性剤の量に対する油相の量の重量比が２乃至１０の範囲にあるもの（例えば先行文献１）や、少なくとも一つの油、少なくとも一つの両親媒性脂質、および少なくとも一つのカチオン性ポリマーを含有しているもの（例えば先行文献２）、少なくとも１つのエトキシル化脂肪酸エステルと、少なくとも１つのソルビタン脂肪酸エステルとを含む混合物と、セチルホスフェートのアルカリ金属塩及びパルミトイルサルコシネートのアルカリ金属塩から選択される少なくとも１つのイオン性界面活性剤を含むもの（例えば先行文献３）、リン脂質とリゾリン脂質及びフェノキシエタノールを含んでいるもの（例えば先行文献４）、ポリオキシエチレン硬化ヒマシ油と常温で流動性のないペースト状油剤を用いた平均粒子径が３００ｎｍ以下のもの（例えば先行文献５）が知られている。 しかしながら、これらナノエマルジョンの短所として、微細な油滴を形成させるために比較的多くの界面活性剤を必要とし、かつ界面活性剤と油性成分との組み合わせを適切に決定しなければ、系全体が不安定となってしまうことが知られている。 In recent years, proposals of cosmetics using nanoemulsion technology have been increasing in the field of cosmetics (a nanoemulsion is a formulation in which an oily component is emulsified in an aqueous component into a particle size of 100 nm or less by a surfactant). Defined in this specification). In general, nanoemulsion forms very fine oil droplets, so its appearance is light blue transparent to light blue translucent, and its application feeling is that oily components are sticky compared to emulsions and creams. Despite being suppressed, it has a characteristic that it has a good moisturizing and penetrating feeling. As an example of a nanoemulsion, an anionic surfactant selected from phosphoric acid fatty esters and their oxyethylenated derivatives and an oily component having a molecular weight of 400 or more are included, and the weight ratio of the amount of the oil phase to the amount of the surfactant is In the range of 2 to 10 (for example, Reference 1) or containing at least one oil, at least one amphipathic lipid, and at least one cationic polymer (for example, Reference 2), at least A mixture containing one ethoxylated fatty acid ester and at least one sorbitan fatty acid ester, and at least one ionic surfactant selected from alkali metal salts of cetyl phosphate and alkali metal salts of palmitoyl sarcosinate. (For example, Reference 3), one containing phospholipids, lysophospholipids, and phenoxyethanol (for example, Reference 4), using polyoxyethylene hydrogenated castor oil, and a paste-like oil agent that is not fluid at room temperature, and having an average particle diameter of 300 nm. The following (for example, prior art document 5) is known. However, the disadvantages of these nanoemulsions are that a relatively large amount of surfactant is required to form fine oil droplets, and if the combination of surfactant and oily component is not properly determined, the entire system will It is known to become unstable.
一方、化粧料のひとつのカテゴリーとして、シートマスクの使用が拡大している。 シートマスクはシートと定義される支持体に化粧料を含浸または塗布した状態で形成されるものであり、主に顔にある一定時間密着させて使用するものであり、その仕様態様上、シートマスクは肌上に化粧料を長時間、密閉しながら作用させることができるため、肌への効果に優れた化粧料として認知されている。 支持体であるシートには、コットンやレーヨンといった繊維からなる不織布や、バイオセルロースや寒天、アクリル酸系などのポリマーなどによるゲル、プラスチックやシリコンゴムなどのフィルムを使用することができ、含浸または塗布する化粧料も化粧水、美容液、クリーム及び紛体といった剤型のものが使用されており、その中でも、使用時の感触や保湿性、価格の面から、不織布に化粧水を含浸させたものが一般的である。 On the other hand, the use of sheet masks is expanding as one category of cosmetics. A sheet mask is formed by impregnating or applying a cosmetic material on a support defined as a sheet, and is mainly used by being in close contact with a face for a certain period of time. Has been recognized as a cosmetic having an excellent effect on the skin, because the cosmetic can act on the skin for a long time while sealing. The support sheet may be a non-woven fabric made of fibers such as cotton or rayon, a gel made of biocellulose, agar, a polymer such as acrylic acid, or a film such as plastic or silicone rubber. The cosmetics used are in the form of lotions, beauty essences, creams, powders, etc. Among them, the non-woven fabric is impregnated with lotion in terms of feel, moisturizing property and price during use. It is common.
しかしながら、不織布に含浸させる化粧料には多くの制約が存在する。特に、製剤の粘度と安定性に関しては、以降に示すような非常に大きな制約がある。すなわち、シートマスクに含浸させる化粧料は、均一に含浸させられる程度に粘度が低く、かつ使用時にタレ落ちない程度に粘度が高いという相反する特性を両立することが必要であり、さらにシートの素材との相互作用によって化粧料自身の安定性が損なわれたり、シートを形成する繊維の絡み合いのサイズよりも油滴が大きい際には油滴が濾しとられてしまい安定性が損なわれたりすることもあることから、支持体であるシートと化粧料の相互作用にも配慮することも求められる。 However, there are many restrictions on the cosmetics with which the nonwoven fabric is impregnated. In particular, there are enormous constraints as described below regarding the viscosity and stability of the preparation. That is, the cosmetic material with which the sheet mask is impregnated must have both the contradictory characteristics of low viscosity so that it can be uniformly impregnated, and high viscosity so as not to drip during use. Stability of the cosmetic itself may be impaired due to the interaction with the oil, or when the oil droplets are larger than the size of the entanglement of the fibers forming the sheet, the oil droplets are filtered out and the stability is impaired. Therefore, it is necessary to consider the interaction between the support sheet and the cosmetics.
また、シートマスクにおいて、その保湿効果が十分であるだけでなく、その外観が透明〜半透明であることは、審美および使いやすさの点で重要である。透明〜半透明であることの利点として、肌上に水のベールを乗せたような期待感を高められること、またシートマスクの仕様態様上、ある一定の時間 顔に密着させるため、使用中に化粧料が髪や服などについても簡単に拭え、跡が気にならないこと、さらには密着している際に肌が透けて見えることにより、むらや隙間なく肌にシートが均一に密着しているかどうかを確認しやすいことが挙げられる。シートマスクに用いる化粧料をナノエマルジョンにすることによって、油性成分を適切に含みながら、かつシートマスクの外観を透明〜半透明にすることが可能となり、効果への期待感と使いやすさのどちらも達成することができる。このようなシートマスク製剤に関しては、油性成分として細胞間脂質類似物質を用いているもの（例えば先行文献６）などの例がわずかに報告されているのみである。 Further, in the sheet mask, not only its moisturizing effect is sufficient but also its appearance is transparent to translucent, which is important in terms of aesthetics and usability. The advantage of being transparent to translucent is that it can increase the expectation that a veil of water is placed on the skin, and due to the specification of the sheet mask, it will be in contact with the face for a certain period of time Make sure that the cosmetics can be easily wiped on hair, clothes, etc., and that the traces do not matter and that the skin can be seen through when it is in close contact, so that the sheet adheres evenly to the skin without unevenness or gaps. It is easy to check if it is. By using nanoemulsion for the cosmetics used for the sheet mask, it is possible to make the sheet mask look transparent to translucent while properly containing oily ingredients. Can also be achieved. With regard to such a sheet mask formulation, only a few examples have been reported, such as those using an intercellular lipid-like substance as an oily component (for example, Prior Art 6).
上記従来技術は、ナノエマルジョンという形態を達成するという点では化粧料として一定の効果を有しており、また肌の状態に対して一定の改善はなされているが、シートマスクという製剤に着目し、その効果を十分に発揮できるまでには至っておらず、かつシートマスクに応用した際の安定性をきちんと充分確認できていない。また、アニオン性界面活性剤やカチオン系活性剤を用いたものは、特に肌上に化粧料を長時間、密閉しながら作用させるシートマスクに用いる場合、肌に対する刺激が懸念される。しかしながら、ノニオン界面活性剤を用いたナノエマルジョンの知見は少なく、透明〜半透明で審美性および使いやすさに優れ、肌への保湿感、浸透感が良くべたつかない使用感触に優れ、肌に刺激がなく肌のかさつきを改善し、肌をなめらかにする、安定性に優れた化粧料が強く望まれていた。 The above-mentioned prior art has a certain effect as a cosmetic in that it achieves the form of a nanoemulsion, and has made certain improvements to the condition of the skin. However, the effect has not been fully demonstrated, and the stability when applied to a sheet mask has not been properly confirmed. In addition, when an anionic surfactant or a cationic surfactant is used, it may cause irritation to the skin, especially when it is used as a sheet mask that allows a cosmetic to act on the skin for a long time while sealing. However, there is little knowledge of nanoemulsion using nonionic surfactant, it is transparent to translucent and has excellent aesthetics and ease of use, it has a good moisturizing and penetrating feel on the skin, has a non-greasy feeling on use, and is irritating to the skin. There has been a strong demand for a cosmetic composition which is excellent in stability and improves the texture of the skin and makes the skin smooth.
本発明者らは上記目的を達成するため鋭意研究を行った結果、２５℃で液体の油と、ポリオキシエチレン付加トリグリセリド骨格を有するノニオン界面活性剤と、ソルビタン脂肪酸エステルであるノニオン界面活性剤とを、適量の水及び分散媒としての多価アルコールと加熱条件で均一に混合することによって生じる透明〜半透明のゲル状中間体を残りの成分中に投入することで、あるいは２５℃で液体の油、ポリオキシエチレン付加トリグリセリド骨格を有するノニオン界面活性剤、ソルビタン脂肪酸エステルであるノニオン界面活性剤、多価アルコール、および水を高圧ホモジナイザーや超音波を用いたナノマイザーにて乳化させることで、透明〜半透明で審美性に優れ、肌への保湿感、浸透感が良くべたつかない使用感触に優れ、肌に刺激がなく肌のかさつきを改善し、肌をなめらかにする、安定性に優れた平均粒子径が８ｎｍ〜１００ｎｍであるナノエマルジョンとなることを見出し、本発明を完成した。 As a result of intensive studies to achieve the above object, the present inventors have found that an oil that is liquid at 25° C., a nonionic surfactant having a polyoxyethylene-added triglyceride skeleton, and a nonionic surfactant that is a sorbitan fatty acid ester are used.

本発明の化粧料は、上述した成分を必須の構成成分とするが、当該組成物には本発明の目的を損なわない範囲で、他の成分、例えば、陰イオン性界面活性剤、両性界面活性剤、非イオン性界面活性剤、油剤、高分子化合物、増粘剤、粉体（色素、樹脂、顔料）、防腐剤、香料、保湿剤、生理活性成分、塩類、溶媒、酸化防止剤、キレート剤、パール化剤、中和剤、ｐＨ調整剤、昆虫忌避剤、酵素等の成分を適宜配合することができる。 The cosmetics of the present invention have the above-mentioned components as essential constituent components, but other components such as anionic surfactants and amphoteric surfactants are included in the composition as long as the object of the present invention is not impaired. Agents, nonionic surfactants, oil agents, polymer compounds, thickeners, powders (colorants, resins, pigments), preservatives, fragrances, humectants, physiologically active ingredients, salts, solvents, antioxidants, chelates Components such as an agent, a pearling agent, a neutralizing agent, a pH adjusting agent, an insect repellent, and an enzyme can be appropriately mixed.
また、本発明の皮膚化粧料には、本発明の目的を損なわない範囲で、生理活性成分を適宜配合することができる。生理活性物質とは、皮膚に塗布した場合に皮膚に何らかの生理活性を与える物質であり、例えば、美白剤、老化防止剤、紫外線防御剤、ひきしめ剤、抗酸化剤、保湿剤、血行促進剤、抗菌剤、殺菌剤、乾燥剤、冷感剤、温感剤、ビタミン類、アミノ酸、創傷治癒促進剤、刺激緩和剤、鎮痛剤、細胞賦活剤、酵素成分等が挙げられる。 Further, the skin cosmetic of the present invention can be appropriately blended with a physiologically active component within the range not impairing the object of the present invention. The physiologically active substance is a substance that gives some physiological activity to the skin when applied to the skin, and for example, a whitening agent, an antiaging agent, an ultraviolet protective agent, a tightening agent, an antioxidant, a moisturizing agent, a blood circulation promoting agent, Examples thereof include antibacterial agents, bactericidal agents, desiccants, cooling agents, warming agents, vitamins, amino acids, wound healing promoters, stimulants, analgesics, cell activating agents and enzyme components.
また、本発明乳化化粧料としては、基礎化粧料、ヘアケア化粧料、ボデイ化粧料等が挙げられる。剤形も目的に応じて任意に選択することができる。すなわち、液状、ジェル状、シート状、エアゾール状等のものが挙げられる。しかしながら、本発明の効果を最大限に発揮するためには、シートマスクとして使用するのが好ましい。シートマスクに用いる化粧料をナノエマルジョンにすることによって、油性成分を適切に含みながら、かつシートマスクの外観を透明〜半透明にすることが可能となり、効果への期待感と効果の実感のどちらも達成することができる。シートマスクに適用する場合、そのナノエマルジョン化粧料の粘度は１０〜４０００ｍＰａ・ｓであることが好ましい。１０ｍＰａ・ｓ未満の場合、多く含浸させると使用時にタレ落ちを生じてしまい、含浸液量を減らす必要が生じてしまい、美容効果が十分に発揮できない場合がある。また、粘度が４０００ｍＰａ・ｓを超えると、不織布シートに均一に含浸させられず、肌上のすみずみまで美容液が行き届かないため、やはり美容効果が十分に発揮できない場合がある。本発明の皮膚化粧料は、一般
の化粧料に限定されるものではなく、医薬部外品、指定医薬部外品、外用医薬品等を包含するものである。
Further, examples of the emulsified cosmetic of the present invention include basic cosmetics, hair care cosmetics, body cosmetics and the like. The dosage form can also be arbitrarily selected according to the purpose. That is, liquid, gel, sheet, aerosol and the like can be mentioned. However, in order to maximize the effects of the present invention, it is preferable to use it as a sheet mask. By using nanoemulsion for the cosmetics used for the sheet mask, it is possible to make the sheet mask look transparent to semi-transparent while properly containing oily ingredients. Can also be achieved. When applied to a sheet mask, the nanoemulsion cosmetic preferably has a viscosity of 10 to 4000 mPa·s. If it is less than 10 mPa·s, if it is impregnated in a large amount, it may cause dripping during use, and it may be necessary to reduce the amount of impregnating liquid, so that the cosmetic effect may not be sufficiently exhibited. When the viscosity exceeds 4000 mPa·s, the nonwoven sheet cannot be uniformly impregnated and the beauty essence does not reach all over the skin, so that the beauty effect may not be sufficiently exhibited. The skin cosmetics of the present invention are not limited to general cosmetics, but include quasi drugs, designated quasi drugs, and external medicines.
