To investigate the unusually strong synergetic effect of the mixture of the zwitterionic sulfobetaine and biosustainable MES surfactants

Abstract: Zwitterionic surfactants carry no net charge at the natural pH with no added electrolyte. This lack of overall charge makes their interactions with bio-systems weaker than those of ionic surfactants. The presence of charges within the overall neutral molecule generally makes them interact strongly with ionic surfactants. The MES represents a promising group of anionic surfactants with improved performance and biocompatibility. Recent ST and LS measurements have shown unexpected strong asymmetric synergy between these two components, and this has potentially important implications for a wide range of applications. However neutron techniques are now essential to understanding this potentially important phenomenon in detail and to discern the underlying mechanism. We request beamtime to investigate the interfacial structure to determine the variation surface composition and structure.
