Numerous studies have focused on finding environmentally friendly substitutes for commonly used petrochemical-based compounds. Our study explores the potential use of poly-L-lysine/rhamnolipids and poly-L-glutamic acid/ethyl lauroyl arginate mixtures, for foam formation and stabilization. Our results demonstrate that adding polyelectrolyte to an oppositely charged surfactant primarily induces a synergistic effect, enhancing foaming properties and extending foam lifetime, mostly due to improved stability and slower drainage of thin foam films in systems containing synthetic polypeptides. The attached dataset presents data on electrokinetic potential, surface tension, foamability and foam stability as well as drainage kinetics of single foam film (lifetime and thickness time evolution) determined in solutions of poly-L-lysine, rhamnolipids, poly-L-glutamic acid and ethyl lauroyl arginate and their various mixtures.
