Abstract

The aggregation behavior of mixed micellar solutions of cationic hexadecylpiperidinium surfactants and nonionic surfactant Tween 80 is studied. The critical micelle concentration is determined by varying the component ratios, and a negative deviation from the ideal mixing model can be observed (synergistic effect). The adsorption parameters and surface potential of mixed micelles are estimated. The solubilizing effect individual and mixed compositions have on such hydrophobic biologically active compounds as bioflavonoid quercetin and systemic fungicide carboxin is characterized quantitatively via spectrophotometry.

十六烷基表面活性剂和Tween 80的混合胶束溶液：聚集行为和增溶性能

摘要

研究了阳离子十六烷基哌啶表面活性剂和非离子表面活性剂Tween 80混合胶束溶液的聚集行为。临界胶束浓度通过改变组分比率来确定，并且可以观察到与理想混合模型的负偏差（协同效应）。估计了混合胶束的吸附参数和表面电势。单独的和混合的组合物对疏水生物活性化合物如生物类黄酮槲皮素和全身性杀真菌剂羧化物的增溶作用通过分光光度法定量表征。
