Oil-Water Interface

The oil-water interface is the boundary where oil and water meet. Because oil and water are immiscible (they don’t mix), they form separate layers with a distinct boundary. At this boundary, molecules from each substance interact uniquely, creating a surface tension. This interface is important in processes like emulsification, where tiny oil droplets disperse in water, and in oil recovery or environmental cleanup. The properties of this boundary influence how oil and water behave together, affecting everything from industrial applications to biological systems.
