Abstract

Understanding the dissolution process of surfactant solutions is important in formulating product design processes. The main goal of this study is to gain further insights into how additives and mixtures affect surfactant dissolution processes. To achieve this goal, dissipative particle dynamic simulations were used. Lamellar phases at 80% volume of surfactant were initially equilibrated with water. After reaching an equilibrium state, the dissolution simulations were carried out for different surfactant mixtures. To track the dissolution process, different metrics were used, including visual analysis, local concentration analysis, diffusion, and cluster size calculations. Results show that by having a mixture of surfactants, the diffusion of the micelles is not affected only by the size of the micelles as in pure surfactant systems, but there is also an effect due to the composition of the micelles. When oil is added to a surfactant system, the system acts like a longer chain surfactant system, but only when the chain of oil becomes sufficiently long.

混合物和添加剂对溶解表面活性剂层状相的影响
了解表面活性剂溶液的溶解过程对于制定产品设计流程非常重要。本研究的主要目的是进一步了解添加剂和混合物如何影响表面活性剂的溶解过程。为实现这一目标,我们采用了耗散粒子动态模拟。表面活性剂含量为 80% 的片状相最初与水保持平衡。达到平衡状态后,对不同的表面活性剂混合物进行溶解模拟。为了跟踪溶解过程,使用了不同的指标,包括视觉分析、局部浓度分析、扩散和聚类大小计算。结果表明,在表面活性剂混合物中,胶束的扩散不像纯表面活性剂体系那样只受胶束大小的影响,胶束的组成也会产生影响。如果在表面活性剂体系中加入油,该体系就会像长链表面活性剂体系一样发挥作用,但只有当油链变得足够长时才会如此。
