may be described by Otherdistributions1 as shown in Figure 2.1 [2]. In these cases,
the mean drop size is the most commonly used to characterize an emulsion tθ1.

Figure 2.1 Different drop size distributions [2]
Several experimental methods have been used to determine drop sizes in
emulsions, including microscopy, photomicrography, video microscopy, light
scattering, sedimentation, coulter counting, turbidimetry, nuclear magnetic
resonance (NMR) and acoustics among others [7].
2.2.2. Emulsion morphology
The morphology is the most basic characteristic of an emulsion.
Morphologies of different type of emulsions are shown in Figure2.2 [2].
