摘　　要：通过开发一种新型智能动态感应梳理系统实时监测和评价洗护产品在使用过程中的动态梳理力,并以此作为洗护产品在冲洗过程中调理性的评价依据。智能动态梳理系统通过佩戴手指压力感应传感器,用于实时记录在搓揉、冲洗和冲洗后阶段手指握梳子梳理头发施加的力,并计算固定梳理次数下每个阶段的梳理力平均值,用以表征洗护产品使用过程的调理性及每个梳理次数的最大梳理力,用以表征使用过程的纠缠程度。该系统不仅可以实时监控在真人发束上的使用情况,而且可以高效地实现在沙龙研究中评价消费者/志愿者使用洗护产品的全过程。通过动态梳理力评估表明,使用含0.4%丙烯酰胺丙基三甲基氯化铵/丙烯酰胺共聚物(APTAC/ACM共聚物)的预养精华进行预处理的发束,在洗发后,尤其是在冲洗阶段,纠缠和梳理力明显降低。在沙龙研究中,趋势与发束上相同,但动态梳理力增大,并且之间存在更大差异。该结果与消费者研究很好地相关,后者表明对发束使用预养精华进行预处理可以显著减少洗发期间的掉发。A new system has been developed to assess dynamic combing force during washing with shampoo and conditioning on both hair tresses and volunteers’hair in salon studies.The system includes a fingertip sensor(Finger TPS system,PPS,USA)to measure the force applied on comb during shampoo massage and rinsing,and after rinse.For each stage,the hair was combed many times,and the average force,as well as max.and min.force applied,were recorded and analyzed.It shows that the hair tresses,pre-treated with pre-shampoo containing 0.4%acrylamidopropyltrimonium chloride/acrylic amide copolymer(APTAC/ACM copolymer),have significantly lower hair tangling and combing force after shampooing,especially during the rinsing stage.In the salon study,the trends are the same as on hair tresses,but there is a larger difference in the dynamic combing force.The results correlate well with the consumer study that shows pre-shampoo treatment could significantly reduce hair loss during shampooing.
