    • PROBLEM TO BE SOLVED: To provide a composition for treating keratin fibers, especially human hair, enabling having the resistance of its coating to shampooing, having a property improving resistance against external attacks, especially resistance to sebum, being free from the deterioration of keratin fibers, and making the fibers completely independent of one another and nonsticky.SOLUTION: The composition for treating keratin fibers comprises: one or more polyalkene-based supramolecular polymers; one or more block ethylenic copolymers with a polydispersity index I of greater than 2; and one or more volatile solvents. In the composition, the block ethylenic copolymer includes: at least one first block ≥40°C in glass transition temperature (Tg) when made into the corresponding homopolymer, part or the whole thereof ≥40°C in glass transition temperature can be obtained from one or more first monomers; and at least one second block ≤20°C in glass transition temperature (Tg) when made into the corresponding homopolymer, part or the whole thereof ≤20°C in glass transition temperature can be obtained from one or more second monomers; wherein the first block(s) and the second block(s) are mutually linked via random intermediate segment(s) including at least the one first monomer constituting the first block(s) and at least the one second monomer constituting the second block(s).
    • 要解决的问题:提供一种用于治疗角蛋白纤维,特别是人类头发的组合物,其能够具有其涂层耐洗性,具有改善抗外来特性的性能,特别是对皮脂的抗性,没有角蛋白纤维的劣化 ,并使纤维完全彼此独立并且不粘。解决方案:用于处理角蛋白纤维的组合物包括:一种或多种聚烯烃基超分子聚合物; 一种或多种多分散指数I大于2的嵌段乙烯类共聚物; 和一种或多种挥发性溶剂。 在组合物中,嵌段乙烯类共聚物包括:当玻璃化转变温度(Tg)当玻璃化转变温度(Tg)时玻璃化转变温度(Tg)至少≥40℃的至少一个第一嵌段,其玻璃化转变温度的部分或全部≥40℃可以从 一种或多种第一单体; 当玻璃化转变温度(Tg)为玻璃化转变温度(Tg)时,玻璃化转变温度(Tg)中的至少一个第二嵌段≤20℃,玻璃化转变温度的一部分或全部≤20℃可从一种或多种第二单体获得; 其中第一块和第二块通过包括至少构成第一块的一个第一单体和至少构成第二块的一个第二单体的无规中间链段相互连接( S)。
