The spreading of hydrosoluble surfactants on water

Résumé

Heterogeneities in the distribution of surfactants at an interface between two fluids create a gradient of interfacial tension, which triggers the Marangoni effect, i.e., a bulk flow in the two phases surrounding the interface. The Marangoni effect is used to enhance the spreading of liquids on substrates, and some living organisms rely on this to move at the surface of water. It can also impair processes such as surface coating.
