The word surfactant is short for surface active agent. Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or the interfacial tension between a liquid and a solid.In solutions this behavior is known as wetting, and it occurs as a result of surfactants adsorbing to the air/water interface.urfactants affect the behavior of a paint not only during the lifetime of the formed coating but also the initial aggregation and film formation of the paint. Surfactants are also used to stabilize the dispersion of polymer particles during emulsion polymerization in paints and other applications.
