Rapid Stabilization of Immiscible Fluids using Nanostructured Interfaces via Surfactant Association

Niroobakhsh, Zahra; LaNasa, Jacob A.; Belmonte, Andrew; Hickey, Robert J.

Surfactant molecules have been extensively used as emulsifying agents to stabilize immiscible fluids. Droplet stability has been shown to be increased when ordered nanoscale phases form at the interface of the two fluids due to surfactant association. Here, we report on using mixtures of a cationic surfactant and long chained…

The structure of spray-dried detergent powders

Farshchi, Amin; Hassanpour, Ali; Bayly, Andrew E.

The complex multiscale structure of spray dried detergent granules has been characterized using a complementary range of techniques including scanning electron microscopy (SEM), image analysis, wide angle and small angle X-ray scattering (WAXS, SAXS) and X-ray microtomography. A complex composite structure is revealed due to the multiphase nature of the…
