The oil droplets remain suspended due to the repulsive forces generated by the surfactant molecules surrounding them, which prevents them coming back together. These molecules possess both a hydrophilic (water-loving) head and a hydrophobic (oil-loving) tail, allowing them to align at the boundary and reduce the tension.

This tension causes the liquids to minimize contact with each other, leading to the formation of distinct droplets or layers. Understanding the science behind these interactions clarifies why some mixtures are fleeting while others are engineered to be stable.
Water is a highly polar molecule, forming strong hydrogen bonds with other water molecules, which creates a tightly bonded network. To create this type of emulsion, energy must be added to break the oil into small droplets, and an emulsifying agent must be present to stabilize the interface.
Industrial Oil Water Separation Processes for Stable Oil in Water and Water in Oil Emulsions
The creation process is similar to O/W emulsions but requires careful control of the oil content and emulsifier concentration. Butter is another familiar W/O emulsion, consisting of water globules held in a fat matrix.
