Parameters determining emulsion morphology
Formulating emulsions using the HLD method

The morphology of an emulsion is largely determined by the phase behavior of the same S/H/E system at equilibrium, and therefore by the physico-chemical formulation expressed by the HLD value. Three other parameters are also involved:

• the relative proportions of water and oil ;

• the concentration of the surfactant and its ability to form liquid crystals;

• the experimental protocol used to prepare the emulsion.
