The critical micelle concentration (cmc) of Tween-20 was found to increase with increasing amount of [C5mim][BF4]. The significant increase in cmc and decrease in aggregation number (Nagg) indicates an "unfavorable" micellization within aqueous Tween-20 solution when [C5mim][BF4] is present. ...
不同Tween产品的临界胶束浓度（CMC）有所区别，吐温20的CMC约为25克每升，吐温80则约为1.4克每升。这些产品的物理状态和含量也有差异，例如吐温-80、-60和-40通常为黄色粘稠液体，活性物含量在98-99%，而吐温-20可能是膏状物。它们的溶解性广泛，能溶于水、乙醇和油脂，并且具有较高的闪点和浊点。

以高浓度碘的水溶液作为显色剂,用紫外吸收分光光谱法测定非离子表面活性剂Tween20和Tween40的临界胶束浓度(CMC)分别为5.19×10-5 mol/L和1.90×10-5 mol/L,再采用黏度法测定这2种表面活性的CMC分别为5.00×10-5 mol/L和1.93×10-5 mol/L,并研究了不同浓度的NaCl溶液对临界胶束浓度和黏度的影响.结果表明黏...
CMC:0.06 mM (20-25°C) 一般描述: Tween®20是属于聚山梨醇酯家族的一种聚氧乙烯山梨糖醇酯。它是一种分子量为1,225道尔顿的非离子型去污剂,假设有20个环氧乙烷单位、1个山梨糖醇和1个月桂酸作为主要脂肪酸。环氧乙烷亚基负责表面活性剂的亲水性,而烃链则提供了疏水环境。山梨糖醇可形成连接了环氧乙烷聚合...
