Preparation, characterization, and properties of novel meglumine-based polysiloxane surfactants

A series of meglumine-based polysiloxane surfactants, (PSi m-n ) with different numbers of meglumine branches were prepared. The formed surfactants were characterized by FT-IR and NMR techniques. Physiochemical properties, such as surface activity, aggregation behavior, and wettability, were closely examined and used to differentiate the various samples. The findings demonstrate that PSi m-n surfactants possess high surface activity and can wet-out a parafilm surface at all but extremely low concentrations. Furthermore, PSi 6-4, the surfactant with the highest meglumine concentration, can form larger complex aggregates in aqueous solutions.
