Surface active agents and surfactants testing and analysis. Intertek provides detailed characterisation of surface active agents (surfactants). A surface active agent, or surfactant, is a substance which lowers the surface tension of the medium in which it is dissolved, the interfacial tension with other phases, and is positively adsorbed at the liquid-vapour interface and other interfaces.

Surface-Active Agents or Surfactants. Surfactants are molecules having a dual character. Part of each molecule is hydrophilic. Part of each molecule is hydrophobic. The dual affinity means that surfactant molecules have a tendency to accumulate at interfaces between polar and nonpolar phases. Surfactants can help technologists to disperse emulsion particles, spread various liquids onto solids.
