A substance that preferentially accumulates at an interface and changes its free energy, often through molecules containing chemically distinct solvophilic and solvophobic regions.

Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Surfactant molecules adsorb at selected interfaces and alter interfacial free energy and structure; coverage, aggregation, charge, salt, solvent, temperature, and nonequilibrium transport control the effect.
The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.

Micellar populations emerge over a concentration range from competing solvophobic, packing, electrostatic, and mixing contributions rather than at a perfectly sharp universal threshold.
The target is a collective, organizational, or scale-dependent phenomenon of the source constituents and interactions; it is not a mere list or classical sum of constituents.
