Ramsden emulsions have gained increased attention and research interest during the last 20 years when the use of traditional surfactants was questioned due to environmental, health and cost issues. Synthetic nanoparticles as Ramsden emulsion stabilizers with well-defined sizes and compositions have been the primarily particles of interest until recently when also natural organic particles have gained increased attention. They are believed to have advantages such as cost-efficiency and degradability, and are issued from renewable resources. Pickering emulsions find applications for enhanced oil recovery or water remediation. Certain Pickering emulsions remain stable even under gastric conditions and show an extraordinary resistance against gastric lipolysis, facilitating their use for controlled lipid digestion and satiation or oral delivery systems.
