Ostwald Ripening in Sodium Dodecyl Sulfate-Stabilized Decane-in-Water Emulsions

Influence of Oil Polarity on Droplet Growth in Oil-in-Water Emulsions Stabilized by a Weakly Adsorbing Biopolymer or a Nonionic Surfactant

“…A faster droplet growth rate than expected from Ostwald ripening theory has also been observed by other researchers, and may be attributed to some limitation in the Ostwald ripening theory (8,29,30). For example, it has been postulated that the mass transport of oil molecules through the aqueous phase separating oil droplets may be facilitated by the presence of surfactant micelles (29).…”

Influence of surfactant structure on the contribution of micelles to Ostwald ripening in oil-in-water emulsions

“…The equilibrium solubility of oil in micelles, c eq mic , is several orders of magnitude higher than the molecular solubility c eq w of the oil. Yet the enhancement in experimentally measured Ostwald ripening rates, x E , in the presence of micelles, relative to that in their absence, is found to be much weaker than expected based on this solubility increase [7][8][9][10][11][12][13]. Furthermore, studies of systems containing ionic surfactants found that x E was virtually independent of surfactant concentration, leading researchers to conclude that there is no contribution from anionic micelles to the ripening mechanism [7,9,10].…”

Solubilization rates of oils in surfactant solutions and their relationship to mass transport in emulsions

“…Finally, several studies [14,17,41,[43][44][45][46] have dealt with the so-called Ostwald ripening in emulsions (Fig. 10, bottom), a phenomenon in which bigger drops grow at the expense of smaller drops due to the well-known Kelvin effect [47].…”
