    • As used in this context, "dilute" is not an exact definition tied to a specific range of surfactant volume ratios. Rather, it is used generally to define lamellar microemulsions whose surfactant volume ratio is not sufficient to generate the usual stacked lamellar structure. As discussed in our earlier paper [1], the stacked lamellar structure is typically maintained by Helfrich steric repulsions that decay with increasing distance between lamellar sheets. When this lamellar repeating distance is increased sufficiently that the Helfrich interaction is weak, thermal fluctuations will be strong enough to create topological defects in the stacked lamellar structure, leading to the disordered phase observed. At present, there is no theoretical means of deriving the point at which this breakdown in structure occurs, so for now we are confined to using "dilute" as an operational definition.
