ンキに適用された例はあるが、化粧料に適用された例は
ない。Cholesteric liquid crystals could not be printed in the past because they could easily react with oxygen in the air and other substances other than liquid crystals to change their coloration characteristics or become sticky. As a means of protecting against chemical contamination and physical damage of the above, a method of atomizing a liquid crystal and coating the surface with a polymer substance, so-called encapsulation was tried, and there are examples of application to printing inks. There is no example applied to.

ステリック液晶を透明又は半透明化粧料に分散して配合
したとき、各種のデザインを付加するが、運搬や使用に
よってそのデザインがくずれ、その外観の優位性がくず
れる場合があり、透明又は半透明化粧料の選択の幅もせ
まくなる。Cholesteric liquid crystal has a structure similar to the sebum component of the skin and has an emollient effect as an oil agent. However, when a cholesteric liquid crystal is dispersed and mixed in a transparent or translucent cosmetic composition, various designs are added, but the design may collapse due to transportation or use, and the appearance may lose its superiority. The range of choices for cosmetics is also narrow.
従って液晶の利点である外観の有効性を環境或いは使用
によるストレスより保護し、長時間維持することが求め
られている。Therefore, it is required to protect the effectiveness of the appearance, which is an advantage of liquid crystal, from the stress caused by the environment or use and maintain it for a long time.
化粧料には洗顔やマッサージに効果を発揮するスクラブ
剤としての効果も求められている。Cosmetics are also required to be effective as a scrubbing agent that is effective for face washing and massage.
また液晶のもつ欠点であるべたつき感を解消することも
求められている。本発明の目的は運搬や保存中に液晶の
呈色特性が変化したり、べとついたりする難点を解決

粧料を提供することであり、更に、液晶に保湿性を付与
して、べたつき感を解消し、官能面で優れた化粧料を提
供することである。It is also required to eliminate the sticky feeling which is a drawback of liquid crystals. An object of the present invention is to provide a cosmetic that solves the problems that the coloration characteristics of the liquid crystal change or becomes sticky during transportation and storage, and that further utilizes the advantages such as the scrubbing effect of the liquid crystal. Further, the present invention is to provide a liquid crystal with a moisturizing property to eliminate a sticky feeling and to provide a cosmetic excellent in sensory aspect.
本発明はコレステリル12−ヒドロキシステアレートを必
須成分として含むコレステリック液晶をカプセル化し
て、透明あるいは半透明化粧品に分散させてなるカプセ
ル化液晶を含む化粧料である。The present invention is a cosmetic containing an encapsulated liquid crystal obtained by encapsulating a cholesteric liquid crystal containing cholesteryl 12-hydroxystearate as an essential component and dispersing it in a transparent or translucent cosmetic.
このコレステリック液晶を構成するコレステリックエス
テルとしては、コレステリル12−ヒドロキシステアレー
トを必須成分として含有する。更に透明化粧品中又はカ
プセルチ中の液晶にコンキオリン加水分解物を0.1〜20
重量%含有させることが好ましい。The cholesteric ester constituting the cholesteric liquid crystal contains cholesteryl 12-hydroxystearate as an essential component. Furthermore, 0.1 to 20 conchiolin hydrolyzate was added to the liquid crystal in the transparent cosmetic or capsule.
It is preferable to contain it by weight%.
コレステリック液晶をカプセルに封入すれば、非常に強
い変形力が作用しない限り、液晶と透明又は半透明化粧
品の境界が曖昧になることはなく、また使用時には強い
変形力を受け、カプセルが崩壊し、液晶が皮膚に対して
もつ有効性を発揮する。Encapsulating the cholesteric liquid crystal in the capsule does not obscure the boundary between the liquid crystal and the transparent or translucent cosmetic product unless a very strong deforming force acts, and it receives a strong deforming force during use, and the capsule collapses, Liquid crystals exert their effectiveness on the skin.
さらにカプセル化した結果、洗顔やマッサージに効果を
発揮するスクラブ剤としての効果があることも判明し
た。As a result of further encapsulation, it was also found to be effective as a scrub agent that is effective for face washing and massage.
この場合、カプセルの大きさ、硬さを用途に合ったもの
を選択しなければならないのは勿論である。逆にスクラ
ブ効果を期待しないときにはカプセルの膜強度は経時変
化に耐える程度でよい。In this case, it goes without saying that the size and hardness of the capsule must be selected according to the application. On the contrary, when the scrubbing effect is not expected, the film strength of the capsule may be sufficient to withstand the change with time.
カプセル膜の材質としてはゼラチンのほか寒天等が使用
し得る。このように、他のスクラブ剤に比較して硬さの
選択が容易なことも利点であり、また内封する液晶化合
物もそのスクラブの硬度の調整に役立つことは当然であ
る。As the material of the capsule film, agar or the like can be used in addition to gelatin. As described above, it is an advantage that hardness is easily selected as compared with other scrubbing agents, and the liquid crystal compound to be encapsulated is also useful for adjusting the hardness of the scrubbing.
液晶は油剤であり、その分子構造から粘性が高く、べと
ついた感じがまぬがれず使用感に問題がある。コレステ
リック液晶の場合と水溶性物質の場合とでは保湿機構が
異なり、使用感等も考慮したとき、他の保湿成分と組み
合わせた化粧料が望ましい。Liquid crystal is an oily agent, and its molecular structure has high viscosity, and it has a problem in use feeling because it is not sticky. The moisturizing mechanism is different between the cholesteric liquid crystal and the water-soluble substance, and in consideration of the feeling of use, it is desirable to use a cosmetic in combination with another moisturizing component.

は、その構成成分がアミノ酸が主体であり、このアミノ
酸組成が皮膚のアミノ酸構成と類似しているので、液晶
に配合する保湿剤としては最適である。However, in the case of commonly used polyhydric alcohols such as glycerin and propylene glycol, the hygroscopicity is too good, it is difficult to maintain the optimum amount of water on the skin, and the skin water is absorbed into the formulation. , The moisture of the skin may not be properly maintained. Conchiolin hydrolyzate is mainly used as a moisturizing agent to be added to liquid crystals, because its constituent components are mainly amino acids and the amino acid composition is similar to that of skin.

ステアレートは特に抱水性に優れており、他のコレステ
リルエステルに比較して5倍以上の抱水能を示す。従っ
て必須液晶成分としてコレステリル12−ヒドロキシステ
アレートを配合するものである。In addition, as a liquid crystal component, cholesteryl 12-hydroxystearate is particularly excellent in water retention, and has a water retention capacity of 5 times or more that of other cholesteryl esters. Therefore, cholesteryl 12-hydroxystearate is added as an essential liquid crystal component.
コンキオリン加水分解物は液晶と共にカプセル中に内封
させてもよく、またカプセルを配合する透明又は半透明
化粧品中に配合してもよい。The conchiolin hydrolyzate may be encapsulated together with the liquid crystal in a capsule, or may be incorporated in a transparent or translucent cosmetic containing the capsule.
これらを組み合わせることによって、べたつき感のな

膚の水分量に合わせて適度な調節を行い必要な保湿性が
得られる。By combining these, a formulation excellent in sensory aspect without stickiness was obtained. Also, the moisturizing property is adjusted appropriately according to the water content of the skin to obtain the necessary moisturizing property.
