Correspondence between curvature,
packing parameter and hydrophilic lipophilic deviation scales around the phase inversion temperature,
We show in this paper that three ways of characterizing "spontaneous" lateral packing of amphiphiles are
equivalent: the spontaneous curvature, the molecular packing parameter, and the refined
hydrophilicGę/-Elipophilic balance known as HLD (hydrophilicGę/-Elipophilic deviation).
Recognition of this equivalence, with its underlying hypothesis of incompressible fluid with lowest
surface energy, reinforces the single parameter bending energy expression implicit in the classical
papers by Ninham and Israelachvili, as well as all the predictive models of solubilization developed as
