Fundamental Studies of Detergent Action

在一项持续的研究计划中，建议发展对油水表面活性剂体系的平衡和动态行为的改进的基本理解，并评估结果对当前洗涤剂挑战的影响。相行为实验和动态行为的观察将使用视频显微镜与纯组分组成的模型系统进行。然而，重点最终应放在含有纯表面活性剂和/或土壤混合物的系统上，因为混合物是实践中的规则。与工业研究小组的密切互动将继续成为这项工作的重要组成部分。研究的重点之一是确定混合土壤或混合表面活性剂体系中富含表面活性剂的中间相在表面活性剂溶液与土壤接触后才开始形成的极限条件。早期的结果表明，当这些相发生时，无论相行为的细节如何，去污力都会显著提高。因此，这种方法提供了被普遍使用的希望，以确定条件，其中良好的去污性可以为各种各样的普遍广泛关注的系统预期。

In a continuing research program it is proposed to develop an improved fundamental understanding of the equilibrium and dynamic behavior of oil-water-surfactant systems and to assess the implications of the results to current challenges in detergency. Phase behavior experiments and observations of dynamic behavior using videomicroscopy will be carried out with model systems consisting of pure components. However, emphasis shall ultimately be on systems containing mixtures of pure surfactant and/or soils since mixtures are the rule in practice. Strong interaction with industrial research groups investigates detergency will continue to be a significant part of this work. One major emphasis of the research will be to determine the limiting conditions in mixed soil or mixed surfactant systems when surfactant-rich intermediate phases just start to form upon contact of surfactant solution and soil. Early results suggest that detergency improves significantly when such phases occur, whatever the details of the phase behavior. Thus, this approach offers the promise of being of general use to identify conditions where good detergency can be expected for a wide variety of systems of general widespread interest.
