PROBLEM TO BE SOLVED: To provide hair cleansing compositions which reduce a hair friction feeling after hair cleansing, are excellent in the effect which improves smoothness and a texture, such as a finger-combability, have hair damage alleviation effect, without deteriorating foamability and detergency, and are excellent in stability, in order to solve the problems that hair color, bleach, permanent wave, ultraviolet ray in sunlight, friction, heat shock, and the like at the time of hair shampoo or styling damage the cuticle on the hair surface to lose the smoothness of the hair and by losing smoothness the hair becomes more fragile to cause friction at the time of hair cleansing, and dryness and stiffness after drying, which also lead to damage to the interior of the hair and cause not only cuttings and split ends, but also reducing gloss.SOLUTION: A subject is solved by incorporating polyglycerol unsaturated fatty acid ester in which 20 to 100% of its constituent fatty acids is linoleic acid and which has an average degrees of polymerization of 3 to 20.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】ヘアカラーやブリーチ、パーマ、太陽光中の紫外線、ヘアシャンプーやスタイリング時の摩擦やヒートショックなどによって、毛髪表面のキューティクルが損傷し、毛髪のなめらかさが失われる。なめらかでなくなると、更に痛みやすくなり、毛髪洗浄時、きしみ感や、乾燥後のパサツキやごわつきが生じる。また、毛髪内部への損傷にも繋がり、切れ毛や枝毛の原因となるだけでなく、ツヤも低下してしまう。本発明は毛髪洗浄後の毛髪のきしみ感を低減し、なめらかさ、指通り等感触を良好なものとする効果に優れ、毛髪のダメージ軽減効果を持ち、且つ、起泡性、洗浄力を落さず、安定性に優れた毛髪洗浄剤を提供することを目的とする。【解決手段】構成脂肪酸の20~100%がリノール酸であり、平均重合度が3~20であるポリグリセリン不飽和脂肪酸エステルを含有させることで上記課題を解決する。【選択図】なし
