Ikapangidwa ndi ionized m'madzi, imakhala ndi zochitika zapamtunda komanso ndi charged yoyipa yomwe imatchedwa anionic surfactant.
Ma anionic surfactants ndi zinthu zomwe zidakhala ndi mbiri yayitali kwambiri, mphamvu yayikulu kwambiri komanso mitundu yambiri pakati pa opanga ma surfactants. Ma surfactants anionic amagawidwa kukhala sulfonate ndi alkyl sulfate molingana ndi kapangidwe ka magulu awo a hydrophilic, omwe pakadali pano ali magulu akuluakulu a anionic surfactants. The ntchito zosiyanasiyana za surfactant makamaka anapeza mawu kusintha katundu wa madzi pamwamba, madzi-zamadzimadzi mawonekedwe ndi madzi olimba mawonekedwe, amene pamwamba (malire) katundu wa madzi ndi mfundo yaikulu.
