An experimental method for determining the potential barrier of the solvati
on-adsorption stability factor for dispersion systems was proposed. The met
hod is based on kinetic analysis of latex coagulation in the absence of an
electrostatic repulsion barrier at the interaction potential curves. The ef
fect of nonionic surfactants on the value of the potential barrier of the s
olvation-adsorption stability factor for lyophilized dispersion systems was
estimated.
