PROBLEM TO BE SOLVED: To provide a cosmetic patch which can effectively allow a physiologically active component to permeate the skin, has reduced skin irritation, can apply for a long time, and excels in a moist effect.SOLUTION: The patch rejects the use of a support sheet to remove skin irritation which is a common defect of the conventional patches, and the base material is composed of a styrenic thermoplastic elastomer and an oil ingredient, and the main component of the oil ingredient is a liquid hydrocarbon, and the patch is a beauty sheet prepared by dipping this base material in an oily cosmetic liquid. As the composition of the base material, the oil ingredient is set at 100-800 pts.wt. based on 100 pts.wt. styrenic thermoplastic elastomer. When this beauty sheet is applied to the face, the base material is not directly attached to the skin and a thin film (a moist layer) of the oily cosmetic liquid is present between the base material and the skin. Accordingly, the adhesion of the base material to the skin is improved even if it is weak, and moreover, the moist effect on the skin is high and the touch becomes good.COPYRIGHT: (C)2012,JPO&INPIT【課題】生理活性成分を皮膚に有効に浸透させることができ、皮膚刺激作用が小さく、長時間貼付でき、かつうるおい効果に秀でた化粧用貼付剤を提供する。【解決手段】本発明に係る貼付剤は、これまでの貼付剤の共通の欠点である皮膚刺激性を除去するため支持シートの使用を排し、基剤がスチレン系熱可塑性エラストマーとオイル成分からなり、オイル成分の主成分が液状炭化水素であり、この基剤を油性化粧液に浸漬させて作成した美容シートである。基剤の組成は、スチレン系熱可塑性エラストマー100重量部に対し、オイル成分100~800重量部とする。この美容シートを顔面に貼付したとき、基剤は直接肌に接着せず、油性化粧液の薄い膜(うるおい層)が基剤と肌の間に介在する。それため基剤の接着性が弱くても肌への密着性が向上し、しかも皮膚へのうるおい効果が高く、感触も良好となる。
