Electrolyte induced self-assembly of methyl ester sulphonate surfactants

Abstract: The addition of multivalent counterions (Al3+, Mg2+) induces multilayer adsorption of ionic surfactants at interfaces. It is associated with strong wetting conditions, invoking more efficient detergency and delivery of active components to interfaces, and tolerance to hard water conditions. We have recently demonstrated the phenomena with the methyl ester sulphonates, with the added advantage of being synthesised from renewable palm oil sources. These systems have great potential for a wide range of applications of sustainable products. To fully understand the surface phenomena and optimise the conditions for applications we need to characterise the solution self-assembly, as the surface and solution properties are closely related. We propose to use SANS to study the self-assembly of the methyl ester sulphonates in the presence of the multivalent counterions, Al3+, Mg2+.
