Zeta Potential, The Key To Successful Suspensions

Understanding zeta potential allows formulators to move away from a trial-and-error approach to a procedure based on system knowledge. Zeta potential is a measure of the magnitude of the charge repulsion between particles. This can be different from the surface charge of the particle. The zeta potential is a measure of the force at the effective boundary of the particle. It encompasses the slipping plane, an associated layer of solute molecules and ions.
