Emva kokuba i-ionized emanzini, inomsebenzi ongaphezulu kunye ne-negative charge ebizwa ngokuba yi-anionic surfactant.
I-Anionic surfactants ziimveliso ezinembali ende, esona sixhobo sikhulu kunye nezona ntlobo zininzi phakathi kwe-surfactants.I-Anionic surfactants yahlulwe yaba yi-sulfonate kunye ne-alkyl Sulfate ngokwesakhiwo samaqela abo e-hydrophilic, okwangoku awona macandelo aphambili e-anionic surfactants.Imisebenzi eyahlukeneyo ye-surfactant ifunyanwa ikakhulu ekutshintsheni iipropati zomphezulu wolwelo, ujongano lwe-liquid-liquid kunye nojongano olululwelo oluqinileyo, apho umphezulu (umda) iipropati zolwelo zingundoqo.
