Rapid microfluidic phase mapping of SDS:water:butanol

Abstract: Sodium dodecyl sulfate (SDS) is an anionic surfactant, extensively employed in cosmetics and personal care, as well as in pharmaceuticals and food products. Surfactants are generally used in multi-component aqueous formulations, containing co-surfactants, co-solvents and salts, as well as polymers or colloids. Establishing multi-component phase diagrams is complex and time-consuming, given the large parameter space which, in addition to composition, can involve temperature, pressure and non-equilibrium perturbations, such as temperature fluctuations or vibrations, which are known to impact the stability and performance of such systems.This proposal seeks to evaluate a novel microfluidic approach for the rapid phase mapping of a model formulation. We select a ternary mixture of SDS, water and butanol for this demonstration, since its phase diagram has been coarsely determined.
