A Multiscale Approach to the Design and Manipulation of Oil-in-Water Emulsion-Based Products

Stress- and frequency- independent elastic modulus (G′) as a function of the droplet mean diameter D_{[4, 3]} µm for O/W emulsions within a concentration range of 60–90%  (the concentration values in descending order are 90, 80, 70, and 60% ). The exponential fit matches what has been found in previous studies for highly concentrated systems. We show that the relationships are still valid to lower concentrations having 60%  as a lower bound.
