PROBLEM TO BE SOLVED: To provide a hair cosmetic which imparts quick-drying properties to the hair itself after washing and imparts flexibility to the hair after drying in order to reduce the damage of the hair caused by thermal damage due to too much usage of a dryer to the wet hair after washing, friction damage due to a long time brushing, friction damage due to wiping off of moisture by scraping the hair with a towel more than necessary and friction damage due to sleeping with the hair wet.SOLUTION: There is provided a hair cosmetic comprising a perfluoropolyether compound represented by the general formula (1). (m represents an integer of 0 to 5, n represents an average integer of 1 to 20, R1 represents an alkylene group having 2 to 6 carbon atoms, R2 represents an alkyl group having total hydrogen or carbon number of 1 to 8, an aralkyl group or an aryl group, R3 represents an alkyl group having total hydrogen or carbon number of 1 to 8, an aralkyl group or an aryl group, X represents fluorine or a perfluoroalkyl group having 1 to 3 carbon atoms and Z represents NH, N-CH3 or oxygen.)SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】洗髪後の濡れた毛髪に対するドライヤーの使い過ぎによる熱ダメージ、長時間のブラッシングによる摩擦ダメージ、洗髪後の毛髪をタオルで必要以上に擦って水分を拭き取ることによる摩擦ダメージ、毛髪が濡れたまま就寝することによる摩擦ダメージによる毛髪の損傷を軽減するために、洗髪後の毛髪そのものに速乾性を与え、さらに乾燥後の毛髪に柔軟性を与える毛髪用化粧料の提供。【解決手段】一般式(1)で表される、アミノ基を有するパーフルオロポリエーテル化合物を含有する毛髪用化粧料。(mは0~5の整数、nは平均値で1~20の整数、R1は炭素数2~6のアルキレン基、R2は水素又は炭素数の合計が1~8のアルキル基、アラルキル基若しくはアリール基、R3は水素又は炭素数の合計が1~8のアルキル基、アラルキル基若しくはアリール基、Xはフッ素又は炭素数1~3のパーフルオロアルキル基、ZはNH、N-CH3又は酸素を表す。)【選択図】なし
