input for formation of the best emulsion beyond which the excess energy results in
drop coalescence rather than disruption.
In the presence of polymeric stabilizers, the situation is much more complex
and is poorly understood. It can reasonably be assumed, however, that if the stabi-
lizing activity of the adsorbed polymer is based on steric interactions, both the
viscosity of the interfacial layer and osmotic forces in the interstitial region
between drops will contribute to the overall stabilizing effect.
