Abstract
Description
本発明は、２層分離型化粧料組成物に関する物である。 The present invention relates to a two-layer separated cosmetic composition.
近年、時計美容という概念が注目を集めている。生体には時計遺伝子と呼ばれる遺伝子群が存在し、夜の時計遺伝子、昼の時計遺伝子があるといわれている。生体は夜の時計遺伝子、昼の時計遺伝子があるといわれている。生体は夜の時計遺伝子の発現量が２４時間周期で規則正しく変動し、１日のリズム（概日リズム）を作っている。皮膚では時計遺伝子によって、昼に保湿機能、夜にバリア機能回復を周期的にコントロールしているといわれている。しかしながら、時計遺伝子によるコントロールは睡眠不足や生活の乱れ、精神的なストレスなど日常生活の乱れにより減弱し、その結果、昼には皮膚水分量の低下、夜は皮膚バリア機能の回復力の低下が起きてしまい、これを日々繰り返すことで肌の不調をもたらしてしまう。時計美容とはこのような昼と夜の肌機能の違いに着目し、それぞれの時間帯に適切なケアをするという概念である。 In recent years, the concept of watch beauty has attracted attention. There are genes called clock genes in living organisms, and it is said that there are night clock genes and day clock genes. It is said that living organisms have a night clock gene and a day clock gene. In a living body, the expression level of a clock gene at night fluctuates regularly in a 24-hour cycle, and a rhythm (circadian rhythm) is created for one day. In the skin, it is said that the clock gene periodically controls the moisturizing function at daytime and the recovery of barrier function at night. However, clock gene control is attenuated by disturbances in daily life such as lack of sleep, disturbed life, and mental stress, resulting in reduced skin moisture at daytime and reduced resilience of skin barrier function at night. I get up, and repeating this daily leads to skin upset. Watch beauty is a concept that focuses on the difference between day and night skin functions and provides appropriate care in each time zone.
また、肌は日中に紫外線や乾燥等により炎症等のダメージも受ける。バリア機能が低下した状態では肌が受けるダメージも多くなってしまう。夜は肌が日中に受けたダメージからの回復とバリア機能の回復によって翌日に備える時間帯であり、この時間帯のスキンケアが特に重要になる。ダメージからの回復とバリア機能の回復には肌が余分な外的刺激を受けないことが重要である。そのため肌を保護することが重要である。 In addition, the skin also suffers damage such as inflammation due to ultraviolet rays and drying during the day. When the barrier function is reduced, the skin suffers more damage. At night, the skin is prepared for the next day by recovering from the damage received by the skin during the day and recovering the barrier function. Skin care during this time is particularly important. It is important that the skin is not exposed to extraneous irritation for recovery from damage and recovery of barrier function. Therefore, it is important to protect the skin.
肌を保護するためには、油分を多量に必要とする。例えば、特許文献１に開示されているようなワセリン様のペースト状油剤（バーム）があるが、べたつきが強いこと、伸びが悪いこと、肌なじみが悪いこと、みずみずしさがないことから、肌へ部分的に使用する場合には適するものの、顔全体のような広範囲に使用する場合には適さない。 A large amount of oil is required to protect the skin. For example, there is a vaseline-like paste oil (balm) as disclosed in Patent Literature 1, but because of its strong stickiness, poor elongation, poor skin familiarity, and lack of freshness, it can be applied to the skin. It is suitable for partial use, but not suitable for wide use such as the entire face.
上記問題を解決する方法として、２層式の化粧料とすることが考えられる。２層式の化粧料とは、水層と油層を意図的に分離させておき、使用時に振とうして使用する剤型である。乳液等の乳化物は乳化安定性を維持することが困難になるため多量の油を入れることが難しいが、２層式の化粧料であれば、乳化安定性の問題がないため、多量の油分を入れることがき、かつ水層によってみずみずしさも両立することができる。また見た目も美しいことから審美性にも優れた好ましい剤型である。 As a method of solving the above problem, it is conceivable to use a two-layer cosmetic. The two-layer type cosmetic is a dosage form in which an aqueous layer and an oil layer are intentionally separated and shaken when used. For emulsions such as emulsions, it is difficult to maintain a large amount of oil because it is difficult to maintain emulsion stability. And the water layer can also balance freshness. Further, since it is beautiful in appearance, it is a preferable dosage form excellent in aesthetics.
２層式の化粧料としては、例えば、液状油、水性成分、ＨＬＢ２〜４のイソステアリン酸ポリグリセリルを配合して使用時のみ振とうにより乳化状態とし、静置時には２層に分離させる技術などがある（特許文献２） As a two-layer cosmetic, for example, there is a technique of mixing a liquid oil, an aqueous component, and polyglyceryl isostearate of HLB2 to 4 to form an emulsified state by shaking only at the time of use, and separating it into two layers at the time of standing. (Patent Document 2)
しかしながら、特許文献２の技術では、油層と水層の２層に分離するが、肌なじみ感の高いエステル油などの極性油を多く含有すると、混合後の再分離の際に水と油の界面に白濁層を生じるため、外観に優れた２層式の化粧料が困難な場合があった。 However, according to the technique of Patent Document 2, although it separates into two layers of an oil layer and an aqueous layer, if a large amount of polar oil such as ester oil having a high skin familiarity is contained, the interface between water and the oil may occur during re-separation after mixing. In some cases, a two-layer cosmetic having an excellent appearance was difficult because of the formation of a cloudy layer.
また、界面の平衡を保つためには表面張力が低い低級アルコールを使用する必要があり、低級アルコールの含有量を多くしすぎると、うるおい感が悪くなり、使用感の満足できる２層式の化粧料が困難であった。一方で乾燥感を下げるために、２５℃で液状の炭化水素油の含有量を多く配合すると、肌へのなじみが悪くなり、使用感を満足させる２層式の化粧料が困難であった。また、振とう後の状態を維持するために非イオン性界面活性剤を使用すると、塗布した際の肌なじみ、うるおい感が悪くなり、使用感を満足させる２層式の化粧料が困難であった。 In addition, in order to maintain the interface equilibrium, it is necessary to use a lower alcohol having a low surface tension. If the content of the lower alcohol is too large, the feeling of moisture deteriorates, and a two-layer type makeup that can satisfy the feeling of use is obtained. The fee was difficult. On the other hand, if the content of the hydrocarbon oil liquid at 25 ° C. is increased in order to reduce the feeling of dryness, the adaptation to the skin becomes worse, and a two-layer cosmetic which satisfies the feeling of use is difficult. In addition, when a nonionic surfactant is used to maintain the condition after shaking, the two-layer cosmetic which satisfies the feeling of use becomes difficult because the skin adaptation and moist feeling when applied are deteriorated. Was.
したがって、使用時には振とうすることで乳化状態を一定時間保持し、しばらく静置した後は２層間の界面が白濁することなく２層に分離し、その界面も並行で外観の審美性が高く、塗布した際の肌のなじみ、うるおい感に富んだ２層分離型化粧料の開発が望まれていた。 Therefore, at the time of use, the emulsified state is maintained for a certain period of time by shaking, and after standing for a while, the interface between the two layers is separated into two layers without clouding, and the interface is also parallel and has a high aesthetic appearance, There has been a demand for the development of a two-layer separation type cosmetic that is rich in skin familiarity and moisture when applied.
本発明者は、上記課題を解決するために鋭意検討した結果、２層分離型化粧料組成物であって、（Ａ）２５℃で液状の炭化水素油、（Ｂ）エタノール、（Ｃ）ヒドロキシエチルセルロースを含有し、界面活性剤を含有しないことを特徴とする２層分離型化粧料組成物を提供することにある。 The present inventors have conducted intensive studies to solve the above problems, and as a result, have been found to be a two-layer separation type cosmetic composition, wherein (A) a hydrocarbon oil which is liquid at 25 ° C, (B) ethanol, and (C) hydroxy. An object of the present invention is to provide a two-layer separated cosmetic composition containing ethyl cellulose and not containing a surfactant.
本発明によれば、肌へのなじみ、うるおい感がよく、べたつき感がなく、振とう後の再分離性がよい２層分離型化粧料組成物が得られる。 ADVANTAGE OF THE INVENTION According to this invention, the two-layer-separation type cosmetic composition which has a good familiarity with skin, a good moisture feeling, no stickiness, and a good re-separation property after shaking is obtained.
以下、本発明を詳細に説明する。なお、含有量を示す単位は、特に明記しない限り全て質量％である。 Hereinafter, the present invention will be described in detail. Units indicating the contents are all mass% unless otherwise specified.
本発明において、「振とう」とは、２層分離型化粧料組成物を適切な容器に充填した後、上下に強く振り混ぜることをさす。 In the present invention, "shaking" refers to shaking up and down strongly after filling a two-layer separation type cosmetic composition into an appropriate container.
本発明者は、２層分離型化粧料組成物であって、（Ａ）２５℃で液状の炭化水素油、（Ｂ）エタノール、（Ｃ）ヒドロキシエチルセルロースを含有し、界面活性剤を含有しないことを特徴とする２層分離型化粧料組成物である。 The present inventor is a two-layer separation type cosmetic composition, which contains (A) a hydrocarbon oil which is liquid at 25 ° C., (B) ethanol, and (C) hydroxyethyl cellulose, and does not contain a surfactant. It is a two-layer separation type cosmetic composition characterized by the following.
