The surface tension behavior of oppositely charged polyelectrolyte/surfactant mixtures is still not agreed. On the one hand, systems have been categorized into different types in the literature and data have been rationalized using models of complex adsorption at chemical equilibrium. On the other hand, coming from a non-equilibrium perspective, we have published a common approach where the surface tension for all systems can be predicted on the basis of a depleted surfactant solution following slow comprehensive precipitation. In a paper earlier this year, our data on the PSS/DTAB system showing a surface tension peak (previously not expected) were dismissed as artifacts due to the high molecular weight of the polymer. Our new surface tension measurements on samples with smaller polymers (like those used originally) indicate that this dismissal was rash as again a peak evolves slowly over one month. However, we are missing critical data on the interfacial composition to publish a rigorous response. This additional FIGARO experiment will provide key data in a paper that aims to help to resolve the disagreement on this issue.
