The notion of »non-equilibrium surface forces« is advanced for the application in a number of cases of colloid stability and transport phenomena. The idealized concept of full equilibrium in the double layer, as used in the DLVO theory is shown to be too simple to describe the stability of a colloid particle not in equilibrium with the surrounding medium. Cases are described where surface forces are stipulated by adsorption layer effects, controlled by diffusion, such as flotation, crystal growth, hydrodynamic transport, and in describing the stability of living cells in suspension.
