阳离子聚合物对香波留香作用的研究

Study of the function of cationic polymers in shampoo for fragrance long-lasting performance

以阳离子聚合物在洗发水中的絮胶和沉积技术为基础,创新的使用荧光光谱技术测试香精在发丝上的沉积,并结合香气强度感官评价对比了阳离子瓜尔胶和丙烯酰胺丙基三甲基氯化铵/丙酰胺共聚物(Poly APTC-ACM)对不同类型香精的沉积效果和留香效果。结果表明,阳离子聚合物Poly APTC-ACM可以持续有效提升不同类型香精在头发上的沉积量,尤其是受损头发。香气强度感官评价也表明含Poly APTC-ACM的香波处理的发束具有显著的48 h持久留香效果。在成品香波中添加Poly APTC-ACM后香精沉积量和消费者半头测试表明,Poly APTC-ACM不仅具有持久留香效果,同时可以改善香波的整体调理表现。

Based on the technologies of coacervation and deposition of cationic polymers in shampoo, the technique of fluorescence spectroscopy was innovatively used to analyze the deposition of perfume on hair fibers, in combination with the sensory evaluation of fragrance intensity. The deposition and fragrance longlasting performances of cationic guar gum were compared with that of Poly APTC-ACM. The results show that Poly APTC-ACM can effectively enhance the deposition levels of perfumes of different types on hair( especially damaged hair). The results of the sensory evaluation of fragrance intensity also show that the hair switches treated with the shampoo containing Poly APTC-ACM have shown a 48 h long-lasting fragrance. The results of perfume deposition and half-head consumer evaluation for the finished product of shampoo added with Poly APTC-ACM show that Poly APTC-ACM can improve not only the fragrance long-lasting performance but also the whole conditioning performance of shampoo.
