My project will focus on characterising and determining the interfacial and dilute solution properties of anionic(sulfonate based) surfactants containing a cyclic component such as furan or cyclohexane. I will aim to make a directcomparison between structures with and without the cyclic component to understand its importance in relation to thesurfactants properties and effectiveness for use in cleaning products. I will also explore whether the aromaticity of thecyclic component plays an important role in the surfactants properties. During the academic portion of my project, myobjectives will be to use advanced characterisation techniques such as small angle x-ray scattering, surface tension,conductivity and neutron scattering to determine the critical micelle concentrations, variation in the packingparameter, (i.e. if they form curved or planar membranes) and compatibility with other formulation ingredients such assalts and other surfactants. My primary supervisor, Professor Karen Edler, will advise me with her extensiveknowledge of surfactants, surface interactions and phase behaviour. My secondary supervisor, Dr Simon Lewis, willcontribute his expertise in surfactant synthesis and access to his laboratory, which is equipped for this type ofsynthetic work. During the industrial placement with Unilever, my objectives will be to understand how the structuresand properties of the surfactants, synthesised during the academic portion, effect the performance when used withina cleaning product formulation. The overarching goal of my project is to find an effective biobased alternative to thecommercially used surfactant, linear alkylbenzene sulfonate (LAS) to reduce the dependency on finite petrochemicalsand formulate more sustainable products for the future. This research also aligns with the Engineering and PhysicalSciences Research Councils (EPSRC) goals of discovery and innovation for the benefit of society and the economy.

我的项目将集中在表征和确定的界面和稀溶液性质的阴离子（磺酸盐基）表面活性剂含有一个环状组分，如呋喃或环己烷。我的目标是直接比较含有和不含环状组分的结构，以了解其在清洁产品中使用的表面活性剂性能和有效性方面的重要性。我还将探讨环组分的芳香性是否在表面活性剂性质中起重要作用。在我的项目的学术部分，我的目标将是使用先进的表征技术，如小角X射线散射，表面张力，电导率和中子散射，以确定临界胶束浓度，在packingparameters的变化，（即，如果他们形成弯曲或平面膜）和与其他配方成分，如assalts和其他表面活性剂的兼容性。我的主要导师Karen Edler教授将用她在表面活性剂、表面相互作用和相行为方面的丰富知识为我提供建议。我的第二导师，西蒙刘易斯博士，将贡献他在表面活性剂合成方面的专业知识，并进入他的实验室，该实验室配备了这类合成工作。在与联合利华的工业实习期间，我的目标是了解在学术部分合成的表面活性剂的结构和性质如何影响清洁产品配方中使用时的性能。我的项目的首要目标是找到一种有效的生物基替代品的商业使用的表面活性剂，直链烷基苯磺酸盐（LAS），以减少对有限的石油化学品的依赖，并制定更可持续的产品的未来。这项研究也符合工程和物理科学研究委员会（EPSRC）的发现和创新的目标，以造福社会和经济。
