Ngenxa yokuncibilika okuphansi kwezinto eziqinile ezithile emanzini, lapho okukodwa noma okuningana kwalezi zinto eziqinile zikhona ngobuningi kusisombululo esinamanzi futhi zinyakaziswa amandla angaphansi kwamanzi noma angaphandle, zingaba khona esimweni se-emulsification ngaphakathi kwamanzi, zakha i-emulsion. Ngokombono, isistimu enjalo ayizinzile. Kodwa-ke, lapho kukhona ama-surfactants (njengezinhlayiya zenhlabathi), i-emulsification iba nzima, okwenza kube nzima nakakhulu ukuthi lezi zigaba ezimbili zihlukane. Lokhu kuvame ukubonwa ezingxubeni zamanzi kawoyela ngesikhathi sokuhlukaniswa kwamanzi kawoyela nasezixubeni zikawoyela wamanzi ekuhlanzeni amanzi angcolile, lapho kwakheka khona uwoyela emanzini noma uwoyela emanzini izakhiwo ezinzile phakathi kwezigaba ezimbili. Isisekelo setiyetha salesi simo "isakhiwo sezendlalelo ezimbili."
Ezimweni ezinjalo, ama-agent amakhemikhali athile athulwa ukuphazamisa isakhiwo esizinzile se-double-layer futhi aphazamise uhlelo lwe-emulsified, ngaleyo ndlela kufinyelele ukuhlukaniswa kwezigaba ezimbili. Lawa ma-ejenti, asetshenziswa ngokukhethekile ukuphula ama-emulsion, abizwa ngokuthi ama-demulsifiers.
I-demulsifier yinto esebenza phezulu ephazamisa ukwakheka koketshezi lwe-emulsified, ngaleyo ndlela ihlukanise izigaba ezahlukahlukene ngaphakathi kwe-emulsion. I-demulsification kawoyela ongahluziwe isho inqubo yokusebenzisa isenzo samakhemikhali esikhipha amanzi ukuze kuhlukaniswe uwoyela namanzi engxubeni yamanzi kawoyela e-emulsified, ukufeza ukuphelelwa amanzi emzimbeni kawoyela ongahluziwe ukuze kuhlangatshezwane nezindinganiso ezidingekayo zokuqukethwe kwamanzi ezokuthutha.
Indlela ephumelelayo neqondile yokuhlukanisa izigaba eziphilayo nezamanzi ukusetshenziswa kwama-demulsifiers ukuze kuqedwe i-emulsification futhi kuphazamise ukwakheka kwesixhumi esibonakalayo esiqine ngokwanele se-emulsification, ngaleyo ndlela kuzuzwe ukuhlukaniswa kwesigaba. Kodwa-ke, ama-demulsifiers ahlukene ayahluka ekhonweni lawo lokususa i-organic phases, futhi ukusebenza kwawo kunomthelela ngokuqondile ekusebenzeni kahle kokuhlukaniswa kwesigaba.
Ekukhiqizeni i-penicillin, isinyathelo esibalulekile sibandakanya ukukhipha i-penicillin emhluzweni wokuvutshelwa kusetshenziswa i-organic solvent (njenge-butyl acetate). Ngenxa yokuba khona kwezinto eziyinkimbinkimbi kumhluzi wokuvutshelwa-njengamaprotheni, ushukela, ne-mycelia-ukuxhumana phakathi kwezigaba eziphilayo kanye nezamanzi akucaci, kwenza isifunda se-emulsification emaphakathi, esithinta kakhulu isivuno somkhiqizo wokugcina. Ukuze kubhekwane nalokhu, ama-demulsifiers kufanele aqashwe ukuze aphule i-emulsion, aqede isimo se-emulsified, futhi afinyelele ukuhlukaniswa kwesigaba esisheshayo nesisebenzayo.
