Emulsions are liquid-in-liquid dispersions of technological importance in diverse ﬁelds of application including foods, pharmaceuticals, and cosmetics. Simple emulsions (100nm<a<1um) are comprised of liquid droplets dispersed in a liquid. thermodynamically unstable, so kinetic stabilization requires emulsiﬁers, such as surfactants, polymers, and nanoparticles. Although a general understanding of the role of emulsiﬁers in the kinetic stabilization has been developed during the last three decades, many details remain unclear. Hence, the formulation of stable dispersions largely relies on an empirical approach. We discuss ground-based measurements for emulsion formulations and underscore the importance microgravity in deconvoluting thermophysical processes related to emulsion stability.
