I-Emulsifier iwuhlobo lwento engenza ingxube yezingxenye ezimbili noma ngaphezulu ezingahlangani zibe i-emulsion ezinzile.Isimiso sayo sesenzo sisenqubo ye-emulsion, isigaba esihlakazekile ngendlela yamaconsi (ama-microns) ahlakazekile esigabeni esiqhubekayo, kunciphisa ukungezwani kobuso bengxenye ngayinye ohlelweni oluxubile, futhi indawo engaphansi ukuze yakhe ifilimu eqinile noma ngenxa yokushaja i-emulsifier inikezwa ekubunjweni kwamaconsi engqimba ephindwe kabili kagesi, kuvimbela amaconsi ukuthi ahlangane, futhi alondoloze umfaniswano. I-emulsion.Ngokombono wesigaba, i-emulsion isahluka kakhulu.Isigaba esihlakazekile ku-emulsion singaba yisigaba samanzi noma isigaba samafutha, iningi lazo eliyisigaba samafutha.Isigaba esiqhubekayo singaba amafutha noma amanzi, futhi iningi lazo amanzi.I-emulsifier iyi-surfactant eneqembu le-hydrophilic kanye neqembu le-lipophilic ku-molecule.Ukuze kuvezwe izici ze-hydrophilic noma i-lipophilic ze-emulsifier, "i-hydrophilic lipophilic equilibrium value (value ye-HLB)" ivame ukusetshenziswa.Lapho liphansi inani le-HLB, kulapho izakhiwo ze-lipophilic ze-emulsifier ziqina.Ngokuphambene, inani le-HLB liphezulu, i-hydrophilicity iba namandla.Ama-emulsifiers ahlukahlukene anamanani ahlukene e-HLB.Ukuze uthole ama-emulsion azinzile, ama-emulsifiers afanelekile kufanele akhethwe.
