Current changes towards a more biobased economy have recently created tremendous renewed interest for using lignin as valuable source for chemicals and materials. Here, we present two facile chemical modification routes capable to impart both softwood and hardwood kraft lignins water-solubility across a wide range of pH rendering them competitive with lignosulfonates for most applications. Since molecular characteristics, degree of substitution, count of surface charge and solubility can be adjusted within a wide range, respective modified kraft lignins are promising materials for a wide range of applications.
