Five novel nonionic surfactants were prepared by the reaction of polyethylene glycol of different molecular weights with toluene diisocyanate. The obtained polyurethane polymers were reacted with oleic acid to obtain the nonionic polyurethane surfact
Biosurfactants are amphiphilic compounds produced by microorganisms. They have high surface activity and low critical micelle concentrations (cmc), and therefore are promising substitutes for synthesized surfactants. Biosurfactants have several advan
