The Fundamentals of Formulation Science: Controlling the microstructure of lamellar polycrystalline formulations under dynamic consumerrelevant proces

结构-性能关系是设计和开发用于化妆品、制药和食品的现代材料的关键因素之一。这些物质是复杂的混合物，既不是理想的固体，也不是理想的液体。它们的分子结构、形态和组成控制着对应用性能负责的粘弹性能。该项目旨在了解层状配方的微观结构特征，特别是护发素，在消费者相关的动态过程中，如剪切，稀释和干燥基质。X射线散射将提供一种用于研究模拟护发应用的设置中材料的微观结构响应的方法。将研究这些动态过程，以建立结构-性能关系，从而对产品设计和性能做出明智的决定。新的知识将直接影响化妆品的未来发展。

Structure-property relationships are one of the key factors in design and development of modern materials used in cosmetics, pharmaceutics and foods. These materials are complex mixtures and neither ideal solids nor ideal liquids. Their molecular structure, morphology and composition control the viscoelastic properties responsible for application performance. This project aims to develop understanding of microstructural characteristics of lamellar formulations, specifically hair conditioners, under consumer relevant dynamic processes such as shear, dilution and drying from substrates. X-ray scattering will provide a means for studying the microstructural response of the material in setups that mimic the hair-care application. These dynamic processes will be studied to establish structure-property relationships allowing informed decisions on product design and performance to be taken. New learnings will have direct impact on future development of cosmetic products.
