This study investigates the encapsulation and controlled release of perfume within micellar systems. We explored how perfume-surfactant interactions and micelle structure influence fragrance delivery. Two mixed-micelle systems, one with branched-tail and the other with linear-tail surfactants, were subjected to varying perfume concentrations, dilution, and time. Using small-angle neutron scattering (SANS), gas chromatography-mass spectrometry (GC-MS), and statistical analysis, we determined that micelle size and shape are significantly affected by perfume content and dilution. While both systems exhibited similar trends, the branched-tail system uniquely formed a lamellar phase at higher perfume levels. Our findings reveal a strong correlation between micelle geometry and headspace perfume concentration, highlighting the role of surfactant tail structure. This research provides fundamental insights into perfume-micelle interactions, with potential applications in materials science and active ingredient delivery.

稀释和老化对两种含有水溶助长剂的混合表面活性剂体系中香料释放的影响


这项研究研究了胶束系统中香料的封装和控制释放。我们探索了香料-表面活性剂相互作用和胶束结构如何影响香味传递。两种混合胶束系统，一种具有支化尾部表面活性剂，另一种具有线性尾部表面活性剂，接受不同的香料浓度、稀释度和时间。利用小角中子散射 (SANS)、气相色谱-质谱 (GC-MS) 和统计分析，我们确定胶束的大小和形状受香料含量和稀释度的显着影响。虽然两个系统表现出相似的趋势，但支尾系统在较高的香料含量下独特地形成层状相。我们的研究结果揭示了胶束几何形状与顶空香料浓度之间的密切相关性，突出了表面活性剂尾部结构的作用。这项研究提供了对香料-胶束相互作用的基本见解，在材料科学和活性成分输送方面具有潜在的应用。
