- Аннотация: Mechanism of washing performance of laundry and cleaning formulations involves a number of interfacial phenomena such as wetting of the solution on the textile surface, desorption of the contamination, as well as the formation of new liquid-liquid interfaces for effective solubilisation of the hydrophobic impurities. From the scientific point of view, the abovementioned non-equilibrium processes are accompanied by dynamic supramolecular polymer-surfactant interactions and by competitive adsorption at interfaces on different time-scales. Here we present a methodology based on the analysis of the dynamic surface tension of solutions of anionic surfactants, as well as of their compositions with a polymeric builder (polyacrylic acid) in the environment modelling soft or hard water conditions. We demonstrate that a decisive input into the optimization of the ratio of the surface active components in the model detergent formulation is gained by the measurements of the dynamic surface activity which directly correlates with the cleaning performance. For the further development of the proposed methodology towards effective and sustainable cleaning formulations a close collaboration with industry including tests in practical washing environments are highly desirable.
