Definition aon ábhar a athraíonn airíonna an dromchla go suntasach Reference 'dromchlaghníomhaí'. Hussey, M. Fréamh an Eolais. Coiscéim, Baile Átha Cliath, 2011.
grenzflächenaktiver Stoff | oberflächenaktiver Stoff | oberflächenaktive Substanz | Tensid
de
Definition vorwiegend synthetische organische Verbindungen, die aufgrund ihres Molekülbaus geeignet sind, die Oberflächen-oder Grenzflächenspannung z.B. zwischen Wasser und Öl oder Wasser und Luft zu verringern; Tenside können daher das Emulgieren nicht mischbarer Flüssigkeiten (Öl in Wasser), das Benetzen von Feststoffoberflächen mit Wasser und die Stabilität von Schäumen begünstigen; Einsatz in Waschmitteln und als Emulgatoren in der Lebensmittelindustrie; Reference ---
surfactant | surface active agent | surface-active agent
en
Definition substance which lowers the surface tension of the medium in which it is dissolved, and/or the interfacial tension with other phases, and, accordingly, is positively adsorbed at the liquid/vapour and/or at other interfaces Reference "'surfactant (surface active agent)' (23.5.2023), IUPAC, Compendium of Chemical Terminology, 2nd ed. (the ""Gold Book""). Compiled by A. D. McNaught and A. Wilkinson. Blackwell Scientific Publications, Oxford (1997), Online version (2019-) created by S. J. Chalk."
Comment Usually, surfactants are organic compounds that contain both water-insoluble groups (hydrophobic tails) and water-soluble groups (hydrophilic heads); they are amphiphilic. This enables them to diffuse in water and adsorb at interfaces between air and water, or between oil and water. The tail group can extend out of the bulk water phase, into the air or into the oil phase, while the water-soluble head group remains in the water phase.
