Co-adsorption of eggshell membrane polypeptide-surfactant mixtures at oil-in-water emulsion – SANS study

Abstract: An eggshell membrane polypeptide is highly surface active and effective at emulsion stabilization. We explore how to use SANS to study the interfacial layers surrounding the emulsion drops at the oil/water interface under a range of premixed peptide and SDS concentration. This is then followed by adsorbing peptide onto SDS stabilized emulsion drops. The same expt will then be done in the reverse order to check how SDS can replace the peptide in the peptide stabilized emulsion. We expect the ranges of replacing concentrations are different and these differences may well explain the different emulsion stability as often observed in product formulations. SANS is unique in unraveling such fantastic information about molecular adsorption and replacement at the oil-water interface. As the signals are mostly weak, we request 4 days on SANS2d.
