　上記クレンジングシートでは、クレンジング効果を高めるために、油剤が配合されることが多い。しかしながら、油剤を安定に配合させるために上記クレンジング組成物を乳化状態とすると、油剤を配合しているにもかかわらず、クレンジング力が低下することがある。 In the above cleansing sheet, an oil agent is often blended in order to enhance the cleansing effect. However, when the cleansing composition is emulsified in order to stably blend the oil, the cleansing power may be reduced despite the blending of the oil.
　また、クレンジング用組成物を乳化状態とすると、クレンジング用組成物の粘度が高くなり、上記シート基材にクレンジング用組成物を均一に含浸させることが困難であるという問題がある。一方で、クレンジング用組成物の粘度を低くすると、クレンジング用組成物の保存安定性が著しく低下することがある。 Further, when the cleansing composition is in an emulsified state, there is a problem that the cleansing composition has a high viscosity and it is difficult to uniformly impregnate the cleansing composition into the sheet base material. On the other hand, when the viscosity of the cleansing composition is lowered, the storage stability of the cleansing composition may be significantly reduced.
　特許文献１～５に記載のように、従来、シート基材に含浸される様々なクレンジング用組成物が知られている。しかしながら、従来のクレンジング用組成物では、均一な含浸を達成するための低い粘度と、高い保存安定性と、高いクレンジング力との全ての性能を満足するには至っていない。 As described in Patent Documents 1 to 5, conventionally, various cleansing compositions impregnated in a sheet base material are known. However, conventional cleansing compositions do not satisfy all the performances of low viscosity, high storage stability, and high cleansing power to achieve uniform impregnation.
　本発明の目的は、クレンジング用乳化組成物の２５℃での粘度が比較的低いにも関わらず、クレンジング用乳化組成物の保存安定性に優れており、またクレンジング用乳化組成物の粘度が比較的低いために、クレンジング用乳化組成物をシート基材に均一に含浸させることができることから、格段に優れたクレンジング力を発揮することができるクレンジングシートを提供することである。 The object of the present invention is that the cleansing emulsion composition has excellent storage stability despite the relatively low viscosity at 25 ° C. of the cleansing emulsion composition, and the viscosity of the cleansing emulsion composition is comparable. Therefore, the present invention is to provide a cleansing sheet capable of exerting a remarkably excellent cleansing force because the sheet base material can be uniformly impregnated with the emulsifying composition for cleansing.
　本発明に係るクレンジングシートは、シート基材と、前記シート基材に含浸されているクレンジング用乳化組成物とを備え、前記クレンジング用乳化組成物が、非イオン性界面活性剤と、アクリル酸・メタクリル酸アルキル共重合体と、油剤とを含有し、前記非イオン性界面活性剤が、ジイソステアリン酸ポリオキシエチレングリセリル、モノイソステアリン酸ポリオキシエチレングリセリル及びポリオキシエチレン硬化ヒマシ油からなる群から選択される少なくとも１種であり、前記クレンジング用乳化組成物の２５℃での粘度が１０００ｍＰａ・ｓ以下である、クレンジングシートである。 The cleansing sheet according to the present invention comprises a sheet base material and a cleansing emulsion composition impregnated in the sheet base material, the cleansing emulsion composition comprising a nonionic surfactant, acrylic acid, An alkyl methacrylate copolymer and an oil agent are included, and the nonionic surfactant is selected from the group consisting of polyoxyethylene glyceryl diisostearate, polyoxyethylene glyceryl monoisostearate, and polyoxyethylene hydrogenated castor oil.

In addition, the storage stability of the cleansing emulsion composition can be improved. Furthermore, since the viscosity of the cleansing emulsion composition is relatively low, the cleansing emulsion according to the present invention is remarkably excellent because the sheet base material can be uniformly impregnated with the cleansing emulsion composition. The cleansing power can be demonstrated.
　以下、本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.
　本発明に係るクレンジングシートは、シート基材と、該シート基材に含浸されているクレンジング用乳化組成物とを備える。本発明に係るクレンジングシートでは、上記シート基材に含浸されている組成物は、乳化組成物である。 The cleansing sheet according to the present invention includes a sheet base material and an emulsifying composition for cleansing impregnated in the sheet base material.
