Cover Story: Lignosulfonates are bio based surfactants and specialty chemicals, which are generated by breaking the near infinite lignin network during sulfite pulping of wood. Due to their amphiphilic nature, lignosulfonates are utilized in manifold applications, such as plasticizer, dispersant, and stabilizer formulations. Function and performance are determined by their behavior in aqueous solution and at surfaces and interfaces, which is in turn imposed by the chemical make up. This review hence summarizes the efforts made to delineate the physicochemical properties of lignosulfonates, while also relating to their composition and structure. View this paper.
