Interfaces cost energy
Oil and water tend to reduce contact area by separating.
Emulsifiers stabilize droplets
Molecules that interact with both phases can reduce interfacial tension and slow coalescence.
Droplet size affects texture
Smaller droplets often produce smoother, more stable mixtures.
Emulsions are often temporary
Gravity, droplet collisions and temperature changes can eventually cause separation.
