Description

本発明は、使用感の良好な皮膚洗浄料に関するものである。   The present invention relates to a skin cleanser having a good feeling of use.

従来、洗顔料などの皮膚洗浄料においては、泡立ちの良さ、洗浄力の良さ、洗い流し後のさっぱり感等に優れることから高級脂肪酸のカリウム塩が多用されている。しかしながら、高級脂肪酸のカリウム塩を主成分とした洗浄剤は、泡立ち、洗浄力、洗い流し後のさっぱり感等の優れた性質を有している反面、クリーミィな泡質が得られにくい、洗浄により肌が過度に脱脂されやすい、又は石鹸カス(スカム)が肌に残ることで使用後に肌がつっぱりやすいという性質も有していた。   Conventionally, in skin cleansing agents such as facial cleansers, potassium salts of higher fatty acids have been frequently used because of good foaming, good detergency, and a refreshing feeling after washing. However, detergents based on potassium salts of higher fatty acids have excellent properties such as foaming, detergency, and freshness after washing, but it is difficult to obtain creamy foam quality. Has a property that it is easily degreased excessively, or that the soap residue (scum) remains on the skin, so that the skin tends to be tight after use.

これらを改善する方法として、高級脂肪酸とアシルタウリン塩型、アシルイセチオン酸型、リン酸エステル型、アシルアミノ酸型等の界面活性剤との併用(特許文献1参照。)、また界面活性剤以外の添加剤(例えば、シリコーン化合物や特定の糖脂質、ラフィノース、植物種子粘質物、種々の高分子化合物等)の配合(特許文献2〜8参照)等が提案されている。
また高級脂肪酸のカリウム塩を主成分とせず、アシルグリシン型界面活性剤と特定の高分子化合物を組み合わせることにより上記問題点を改良する試みもなされている(特許文献9参照。)
As a method for improving these, combined use of higher fatty acids and surfactants such as acyl taurine salt type, acyl isethionate type, phosphate ester type and acyl amino acid type (see Patent Document 1), addition of other than surfactants Formulations of agents (for example, silicone compounds, specific glycolipids, raffinose, plant seed mucilage, various polymer compounds, etc.) (see Patent Documents 2 to 8) have been proposed.
In addition, attempts have been made to improve the above problems by combining an acylglycine surfactant and a specific polymer compound without using a higher fatty acid potassium salt as a main component (see Patent Document 9).

しかしながら、近年の消費者ニーズの高まりにより、特に泡質や洗浄後の感触に関しては、これらの方法では十分に満足できるものではなく、更なる改良が望まれている。
従って、本発明の課題は、泡立ちが良く、泡質がクリーミィであり、かつ洗浄後のつっぱり感を感じない皮膚洗浄料を提供することにある。
However, due to increasing consumer needs in recent years, these methods are not fully satisfactory, especially with respect to foam quality and feel after washing, and further improvements are desired.
Accordingly, an object of the present invention is to provide a skin cleanser which has good foaming, foam quality is creamy and does not feel a feeling of tension after washing.

そこで本発明者は、アニオン性界面活性剤に種々の高分子化合物を配合して、その泡質や洗浄後の皮膚の感触について検討してきたところ、アニオン性界面活性剤に(メタ)アクリルアミド/4級化ビニルイミダゾールモノマーを含む共重合体を組み合せれば、従来の皮膚洗浄料に比べて、泡立ち、泡質及び洗浄後の皮膚のつっぱり感のなさのすべてにおいて顕著に優れた皮膚洗浄料が得られることを見出し、本発明を完成した。   Therefore, the present inventor has blended various polymer compounds with an anionic surfactant and studied the foam quality and skin feel after washing. As a result, (meth) acrylamide / 4 was added to the anionic surfactant. Combining a copolymer containing a graded vinyl imidazole monomer provides a skin cleanser that is significantly superior in all of foaming, foam quality, and lack of skin feeling after washing, compared to conventional skin cleanser. The present invention has been completed.

すなわち、本発明は、(A)アニオン性界面活性剤、及び(B)アクリルアミドモノマー又はメタアクリルアミドモノマーに由来する構成単位と4級化ビニルイミダゾールモノマーに由来する構成単位を有する共重合体を含有する皮膚洗浄料を提供するものである。   That is, the present invention contains (A) an anionic surfactant, and (B) a copolymer having a structural unit derived from an acrylamide monomer or a methacrylamide monomer and a structural unit derived from a quaternized vinylimidazole monomer. A skin cleansing agent is provided.

本発明の皮膚洗浄料は、泡立ちが良く、泡質がクリーミィで、かつ洗浄後の皮膚のつっぱり感がなく、特に洗顔料として有用である。   The skin cleansing agent of the present invention is particularly useful as a facial cleanser because it has good foaming, the foam quality is creamy, and the skin does not feel firm after washing.
