Description
本発明は、シャンプー等として用いられる洗浄剤に関するものである。 The present invention relates to a cleaning agent used as a shampoo or the like.
シャンプーにはアニオン界面活性剤が配合されており、その界面活性剤の選択によっては毛髪や頭皮に刺激を与えることがある。オリーブ油ＰＥＧ−７酢酸ナトリウム等のポリオキシエチレン脂肪酸エステルカルボン酸塩は、皮膚に優しい界面活性剤であり、特許文献１には、シャンプーにオリーブ油ＰＥＧ−７カルボン酸ナトリウムを０．０１から１．８質量％配合することが開示されている。 An anionic surfactant is blended in the shampoo, and depending on the choice of the surfactant, it may irritate the hair and scalp. Polyoxyethylene fatty acid ester carboxylate such as olive oil PEG-7 sodium acetate is a skin-friendly surfactant. Patent Document 1 discloses that 0.01 to 1.8 sodium PEG-7 carboxylate is added to shampoo. It is disclosed that it is blended by mass%.
ポリオキシエチレン脂肪酸エステルカルボン酸塩を配合したシャンプーを用いて洗髪を行えば、頭皮への刺激抑制と毛髪への損傷蓄積抑制を期待できるが、このポリオキシエチレン脂肪酸エステルカルボン酸塩の配合のみでは、洗髪の際のシャンプーの泡立ちが悪い、泡が消えやすい、泡のきめ細かさが不十分といった状況となってしまう。これらのことは、シャンプー使用者に一度の洗髪では不十分であるとの印象を与えることも予想され、二度目の洗髪が行われることになると、毛髪及び頭皮の過剰な洗浄を招く可能性がある。また、泡立ち等が不十分であると、洗髪の際の毛髪間の摩擦を引き起こしやすく、毛髪に損傷を与えてしまうことも考えられる。 If you wash your hair with a shampoo containing polyoxyethylene fatty acid ester carboxylate, you can expect to suppress irritation to the scalp and suppress damage accumulation on the hair, but with this polyoxyethylene fatty acid ester carboxylate alone , Shampoo foaming is poor when washing hair, foam tends to disappear, and foam is not fine enough. These are also expected to give shampoo users the impression that a single shampoo is not sufficient, and if a second shampoo is performed, it may lead to excessive shampooing of the hair and scalp. is there. Moreover, when foaming etc. are inadequate, it is easy to cause the friction between hairs at the time of hair washing, and it is also considered that hair is damaged.
本発明は、上記事情に鑑み、ポリオキシエチレン脂肪酸エステルカルボン酸塩が配合され、泡立ち、泡の持続時間、及び泡のきめ細かさに優れる洗浄剤の提供を目的とする。 In view of the above circumstances, an object of the present invention is to provide a cleaning agent that is blended with a polyoxyethylene fatty acid ester carboxylate and is excellent in foaming, foam duration, and foam fineness.
