We have a short webinar break to make space for the IFSCC Congress but will be back on Wednesday 27 / Thursday 28 with Josh Marlow, a University of New South Wales Postdoc, sharing his knowledge of small-angle scattering and how these techniques can be applied to cosmetics with an eye to the future. Cosmetics and therapeutics are complex formulations of numerous chemical components, which can be more readily designed with specific functional properties if the structure of the components is known.

Small-angle scattering techniques such as small-angle neutron scattering (SANS), small-angle X-ray scattering (SAXS), and ultra-small-angle neutron scattering (USANS) are powerful techniques that allow elucidation of the structural properties of systems with dimensions from a few angstroms to hundreds of nanometres, including nanoparticles and colloids. The techniques have a long history of providing fundamental information about the structures of surfactants and polymers, their self-assembly, and interactions. One notable advantage is that measurements are performed in the solution state.

The ability to understand the relevant parameters driving structure and self-assembly in solution, including their response to external stimuli such as temperature and shear and, in the case of neutrons, the ability to change the contrast of analyses, make these techniques perfectly suited to the study of cosmetic and therapeutic formulations. In this work, we discuss how these techniques can be, and have been, applied to cosmetic systems, with an eye to future applications.

Joshua Marlow is a postdoctoral researcher at the University of New South Wales with an expertise in surfactant self-assembly and small-angle scattering, and his work has spanned industry, academia, and government. Having completed his PhD examining the interplay of surfactants and nanoparticles in liquid crystal systems at Monash University, Josh has since worked at the University of Sydney engineering wormlike micelles. Recently at the Australian Nuclear Science and Technology Organisation (ANSTO), Josh was responsible for connecting industrial and commercial users with the unique capabilities afforded by small-angle scattering.
