    • Disclosed is a method for achieving a recallable hair deformation. A composition is applied onto hair, comprising at least one active agent, which, alone or in combination with further compounds, is able, after application to the hair and after carrying out the treatment of hair in accordance with the present invention, to provide a shape memory effect. The hair is brought into a defined (permanent) shape and the permanent shape is subsequently fixed by means of inducing a chemical or physical change of the applied agents, wherein after a desired or undesired deformation, the memory shape of the initial memory shape may be recovered by means of a physical stimulation. Suitable active agents are for example macromers which may be cross-linked to provide shape memory polymers, wherein the permanent shape is fixed by means of the chemical cross-linking of the macromer, providing a shape memory polymer, which possesses at least one transition temperature Ttrans. Suitable active agents are also shape memory polymers, which have hard segments which may be cross-linked by physical interactions having a first transition temperature T′trans, which preferably is at least 10° C. above room temperature, and soft segments having a second transition temperature which preferably is at least 10° C. below T′trans. In addition to the permanent hairdo, a second (temporary) shape can be impressed. Furthermore, disclosed is a method for the recovery of a once programmed permanent hairdo, which has been brought into a temporary shape or which has been deformed in any other way.
    • 公开了一种实现可召回的头发变形的方法。 将组合物施用到头发上,其包含至少一种活性剂,其单独或与其他化合物组合可以在施用到毛发之后以及在进行根据本发明的毛发处理之后提供一种 形状记忆效应。 头发被带入限定的(永久)形状,并且随后通过引起所施加的药剂的化学或物理变化来固定永久形状,其中在所需或不期望的变形之后,初始记忆形状的记忆形状可以是 通过物理刺激恢复。 合适的活性剂是例如可以交联以提供形状记忆聚合物的大分子单体,其中永久形状通过大分子单体的化学交联固定,提供形状记忆聚合物,其具有至少一个转变温度 T 。 合适的活性剂也是形状记忆聚合物,其具有可通过物理相互作用交联的硬链段,其具有第一转变温度T'反式,优选在室温以上至少10℃ ,和具有第二转变温度的软链段,其优选在T'反式以下至少10℃。 除了永久发型,第二(暂时)形状可以印象深刻。 此外,公开了一种用于恢复已经被暂时形成或以任何其它方式变形的一次编程的永久性发型的方法。
