A surfactant is the scientific name for an emulsifier, a.k.a. something that attracts both water and oil molecules and binds them together. These emulsifiers allow for the creation of a vinaigrette that is creamy and won’t separate—truly a beautiful thing.
An emulsion is simply a blend of two liquids that don’t normally bind together, such as oil and vinegar. You do this by adding the oil to the vinegar or other liquid in a slow and steady stream while furiously beating with a whisk or blender.
Similarly, what happens when you mix oil and vinegar? Oil and vinegar do not mix or even if they are mixed they will quickly separate when given the opportunity. Some proteins such as eggs are emulsifiers that will cause oil and vinegar to mix.
Also question is, how do you mix oil and vinegar?
That’s because oil and vinegar don’t naturally mix. No doubt you’ve seen this yourself—shake up a bottle of salad dressing and the two parts come together. Set the bottle down and in seconds, they start to separate again until all the oil is at the top and all the vinegar is at the bottom.

How do you form an emulsion? If you add a drop or two of oil to water you can see that it does not dissolve or combine with the water: the oil floats on the water. If you shake the oil and water together then the oil breaks up into tiny droplets and becomes distributed in the water forming a mixture.
