Abstract
Description
本発明は、容器からこぼれにくく良好な粘弾性を保つゲル状皮膚化粧料に関する。 The present invention relates to a gel-like skin cosmetic that does not easily spill from a container and maintains good viscoelasticity.
一般的に、増粘剤やゲル化剤を配合することで、とろみのあるローションやヘアスタイリング剤のような硬めのゲルを形成することができ、その種類や配合量は目的や用途に応じて調整している。近年では、微細繊維状セルロースがゲル状組成物における一成分として使用することが知られている。（例えば特許文献１～３）。 Generally, by adding thickeners and gelling agents, it is possible to form a hard gel like a thick lotion or hair styling agent, and the type and amount of addition depends on the purpose and use. I'm making adjustments. In recent years, it has been known that microfibrous cellulose can be used as a component in gel compositions. (For example, Patent Documents 1 to 3).
しかし、これらの化粧料は、増粘性に優れているものの、使用時に容器のフタを開ける際、または容器を傾けた時に容器からこぼれやすく使用性に改善の余地があった。 However, although these cosmetics have excellent thickening properties, they tend to spill out of the container when the lid is opened or when the container is tilted during use, leaving room for improvement in usability.
そこで、本発明は上記事情に鑑みてなされたもので、使用時に容器のフタを開ける際、または容器を傾けた時に容器からこぼれにくい良好な粘弾性を有するゲル状皮膚化粧料のための粘弾性増強剤を提供することにある。 Therefore, the present invention has been made in view of the above circumstances, and provides a viscoelasticity for a gel-like skin cosmetic that has good viscoelasticity and does not easily spill out of the container when the lid is opened or when the container is tilted during use. The purpose is to provide an enhancer.
本発明者らは、使用時に容器のフタを開ける際、または容器を傾けた時に化粧料が容器からこぼれ易い原因は、弾性優位の状態であるからであると考え、化粧料に粘性を加え適度な流体性をもつように鋭意検討した。 The present inventors believe that the reason why cosmetics tend to spill out of the container when the lid is opened or when the container is tilted during use is because the cosmetic is in an elastic state. We have made extensive efforts to ensure that it has a fluid property.
その結果、ゲル状皮膚化粧料に、リン酸化修飾セルロースナノファイバーと（アクリレーツ／アクリル酸アルキル（Ｃ１０－３０））クロスポリマー、カルボキシビニルポリマー、キサンタンガム、ヒドロキシエチルセルロースから選ばれる１種または２種以上と多価アルコールを組み合わせた組成物を含有することで、容器からこぼれにくい良好な粘弾性に加え、指取れ性も良好であることを見出し、本発明を完成した。 As a result, gel-like skin cosmetics contain phosphorylated modified cellulose nanofibers and one or more selected from the group consisting of (acrylates/alkyl acrylate (C10-30)) crosspolymer, carboxyvinyl polymer, xanthan gum, and hydroxyethylcellulose. The present invention was completed based on the discovery that by containing a composition containing a combination of polyhydric alcohols, in addition to having good viscoelasticity that prevents spillage from the container, it also has good finger retrieval properties.

本発明のゲル状化粧料のための粘弾性増強剤は、容器からこぼれにくい良好な粘弾性を有する。さらに、指取れ性も良好である。 The viscoelasticity enhancer for gel cosmetics of the present invention has good viscoelasticity that prevents it from spilling out of the container. Furthermore, it has good finger removability.
以下、本発明のゲル状化粧料のための粘弾性増強剤について詳細に説明する。 Hereinafter, the viscoelasticity enhancer for gel cosmetics of the present invention will be explained in detail.
本明細書において、「容器からこぼれにくい」とは使用時に容器のフタを開ける際、または容器を傾けた時に内容物が垂れて落ちてこないことやことを意味する。「指取れ性」とは容器から内容物を指で取る際の密着感を意味する。また「ヨレ」とは擦るなど力を加えた時にゲル状組成物がポロポロと落ちることを意味する。 As used herein, "not easily spilled from the container" means that the contents do not drip when the lid of the container is opened during use or when the container is tilted. "Finger-removability" refers to the tightness when removing the contents from the container with fingers. In addition, "wrinkling" means that the gel-like composition falls off when force is applied such as rubbing.
本明細書において、「粘性」とは物質のねばり性であり流体が持つ性質のことを意味する。ゲル状組成物において粘性が不足すると、容器を傾けると内容物全体が一気に垂れ落ちる。一方、「弾性」とは応力を加えるとひずみが生じるが、応力をなくすと元に戻る性質のことを意味し、ゲル状組成物において弾性が不足すると、容器を傾けた時に徐々に内容物が垂れ落ちやすくなる。そして、「粘弾性」とは、粘性と弾性の両方を合わせた性質のことを意味し、ゲル状組成物において粘弾性が不足すると、容器を傾けるとすぐに内容物が垂れ落ちる。「シェアシニング性」とはせん断速度の増加とともに粘度が減少することを意味し、ゲル状組成物においてシェアシニング性が不足すると、密着感を得られず、内容物を指で少量しか取ることができない。 In this specification, "viscosity" refers to the stickiness of a substance and a property of a fluid. If the gel composition lacks viscosity, the entire contents will drip out at once when the container is tilted. On the other hand, "elasticity" refers to the property of causing distortion when stress is applied, but returning to its original state when the stress is removed.If the gel-like composition lacks elasticity, the contents will gradually collapse when the container is tilted. It will fall off easily. "Viscoelasticity" refers to a property that combines both viscosity and elasticity, and if a gel composition lacks viscoelasticity, the contents will drip as soon as the container is tilted. "Shear thinning property" means that the viscosity decreases as the shear rate increases, and if the gel composition lacks shear thinning property, it will not be possible to obtain a feeling of adhesion, and only a small amount of the content can be removed with fingers. I can't.
