We review the existing literature on asphaltenes at various types of interfaces: oil–water, air–water, gas–oil and solid–liquid, with more emphasis on the oil–water interfaces. We address the role of asphaltene aggregation, recently clarified for asphaltenes in bulk by the Yen–Mullins model. We discuss the questions of adsorption reversibility and interfacial rheology, especially in connection with emulsion stability.

•Asphaltenes adsorb in monolayers or aggregate layers, depending on concentration.•Asphaltenes type and solvent type can be chosen to model crude oils.•There is a clear relation between emulsion stability and surface rheology•Asphaltenes at oil–water, air–water and solid–water interfaces behave similarly.
