SURFACTANTS are powerful substances: Their molecules consist of a hydrophobic hydrogen residue and a hydrophilic group; this composition enables them to attach to the water surface and reduce its surface tension. Thanks to them, grease or dirt can be dissolved with water and washing or cleaning processes are only possible. You can go wash your hands full of joy and conjugate the Latin word origin of the SURFACTANT while soaping: “tendere, tetendi, tentum/tensum” = (on) tense.
