Emulsions are held together by what kind of agent?

Catalyst
Surfactant
Binder
Preservative

The correct answer is: Surfactant

Emulsions are closely associated with the suspension of one liquid within another. As a surfactant, hydrophilic molecules are attached to the surface of the droplets, making the interaction between the two liquids more stable. Catalysts help to speed up chemical reactions, binders hold multiple ingredients together in a formulation, and preservatives inhibit the growth of microorganisms. None of these options directly aid in holding an emulsion together like a surfactant does.
