Description
本発明は、粒径が数百μm〜数十mmサイズのカプセルを、化粧水、美容液、乳液等の外液中に存在させたカプセル入り化粧料に関するものである。 The present invention relates to a capsule-containing cosmetic in which a capsule having a particle size of several hundred μm to several tens of mm is present in an external liquid such as a lotion, a cosmetic liquid, or an emulsion.
従来、この種のカプセル入り化粧料において、カプセルの形成成分として、アルギン酸塩や、寒天、ゼラチン等を用いたものが存在している。例えば、アルギン酸塩を用いたものとしては、そのカプセルは、アルギン酸ナトリウムの水溶液からなる滴下液を水溶性カルシウム塩などの受液中に滴下することにより得ている(特許文献1〜4)。 Conventionally, in this type of capsule-containing cosmetics, there are those using alginate, agar, gelatin or the like as a capsule-forming component. For example, as a capsule using an alginate, the capsule is obtained by dropping a dropping solution made of an aqueous solution of sodium alginate into a receiving solution such as a water-soluble calcium salt (Patent Documents 1 to 4).
また、上記カプセル入り化粧料の中でも、アルギン酸塩とバリウム塩を必須成分とするアルギン酸バリウム系カプセルとしたものは、pH4〜11という広いpH領域において、カプセルが安定で壊れないので、共存可能な物質や処理条件の選択枝が広く、性能や使い勝手を含め化粧料として最適の設計ができるとしている(特許文献4)。 Among the above-mentioned capsule-containing cosmetics, those made into barium alginate-based capsules containing an alginate and a barium salt as essential components are substances that can coexist because the capsule is stable and does not break in a wide pH range of pH 4-11. In addition, the selection of treatment conditions is wide, and it is said that an optimum design can be made as a cosmetic including performance and usability (Patent Document 4).
この種のカプセル入り化粧料において、カプセルはその内部に有効成分を安定した状態で含有させることができると共に、使用時に肌に軽く押し付けることにより、容易に擦壊して皮膚上に滑らかに展延するというように、使用感に優れたものが望まれている。 In this type of capsule-containing cosmetic, the capsule can contain the active ingredient in a stable state, and can be easily rubbed and spread smoothly on the skin by being lightly pressed against the skin during use. As described above, a material with excellent usability is desired.
しかしながら、上記従来のカプセル入り化粧料において、特許文献1〜3に示されたものでは、カプセルのpH領域における安定性については言及されていないが、カプセルを外液中に存在させておくと、その外液のpH値が低い場合にはカプセルが不安定になり、使用できる外液の種類が限られてしまったり、使用感が低下してしまったりしていた。
また、高温で保管する場合、カプセルが不安定になるという課題を有していた。
However, in the above conventional capsule-containing cosmetics, in Patent Documents 1 to 3, the stability in the pH range of the capsule is not mentioned, but if the capsule is present in the external liquid, When the pH value of the external liquid is low, the capsule becomes unstable, and the types of external liquid that can be used are limited or the feeling of use is reduced.
Moreover, when it stored at high temperature, it had the subject that a capsule became unstable.
さらに、上記従来のカプセル入り化粧料において、特許文献4に示されたものでも、広いpH領域において安定ではあるが、pH4を境界として、これよりpHが低くなると急激に不安定になり、カプセルのゲルがかたまり、使用感も低下してしまうという課題を有していた。 Furthermore, in the above conventional capsule-containing cosmetics, even those disclosed in Patent Document 4 are stable in a wide pH range, but at pH 4 as a boundary, when the pH becomes lower than this, the capsules rapidly become unstable. There was a problem that the gel was agglomerated and the usability was also lowered.
そこで、本発明は、新たに植物由来の原料であるペクチンを利用し、カプセル化したものを外液中に存在させることによって、その外液がpH4未満でも、高温に保管しても、安定した状態で保存でき、ポンプ容器等から吐出して肌に塗り広げる際にも、ゲルのかたまりが残らず伸びが良く使用感のよい新たなカプセル入り化粧料を提供することを目的としてなされたものである。 Therefore, the present invention makes use of pectin, which is a new plant-derived raw material, and makes the encapsulated product exist in the external liquid, so that the external liquid is stable even if it is less than pH 4 or stored at a high temperature. It can be stored in the state, even when spread on the skin and discharged from the pump chamber or the like, which has been made for the purpose of providing a good new encapsulated cosmetic elongation is good feeling does not remain lumps gel is there.
本発明のカプセル入り化粧料は、0. 1〜5重量%のペクチンと、1〜15重量%の比重調整剤および1〜15重量%の粘度調整剤を配合し、0. 1〜10重量%の分散剤を配合した配合成分とを、混合した水溶液からなる滴下液を、0. 1〜5重量%の水溶性金属塩の受液中に滴下することにより得たカプセル(A)を、pH3.5〜6. 5の外液(B)中に存在させたものとしている。 The encapsulated cosmetic of the present invention contains 0.1 to 5% by weight of pectin, 1 to 15% by weight of a specific gravity adjuster and 1 to 15% by weight of a viscosity adjuster, and is 0.1 to 10% by weight.
