Surfactants, or in other words, surface active agents are organic compounds that reduce surface tension when added to water or any other liquid. Therefore, it helps liquid penetrate the surface of the material by helping it spread easily. The nature of a surfactant molecule is having its two ends attached by a covalent bond. These two ends have diametrically opposed polarities. The strongly polar end is lyophobic (having low attraction for organic molecules), whereas the non-polar end is lyophilic (strongly attracted to organic molecules) (water-loving). The molecule aligns itself with respect to the polarity of the surfaces it meets as a result of its dual polarity.
