The current study represents the excellent performance of oxidized kraft, organosolv, and hydrolysis lignins as dispersant for special carbon black (CB). The special CB dispersions were analysed at first day of preparation and after two weeks. Stable suspension of special CB was obtained with all the studied LigniOx samples, which was indicated by zeta potential, viscosity and particle size measurements. LigniOx lignins outperform the performance of the commercial polyacrylic acid and lignosulfonate-based dispersants produced for special CB.
