I-Emulsifier luhlobo lwezinto ezinokuthi zenze umxube wamacandelo amabini okanye ngaphezulu angabonakaliyo abumba i-emulsion ezinzileyo.Umgaqo wayo wesenzo ukwinkqubo ye-emulsion, isigaba esihlakaziweyo ngendlela yamaconsi (microns) ahlakazekile kwisigaba esiqhubekayo, oko. kunciphisa ukunyanzeliswa kobuso becandelo ngalinye kwinkqubo exubeneyo, kunye nomphezulu wedropha ukwenza ifilimu eqinileyo okanye ngenxa yentlawulo ye-emulsifier inikezelwa kwi-droplet surface formation of electric double layer, ukukhusela amathontsi aqokelelane, kunye nokugcina iyunifomu. I-emulsion.Ukususela kwinqanaba lokujonga, i-emulsion iseyi-heterogeneous.Isigaba esihlakaziweyo kwi-emulsion sinokuba sisigaba samanzi okanye isigaba se-oyile, uninzi lwazo luyisigaba seoli.Isigaba esiqhubekayo sinokuba yioli okanye amanzi, kwaye uninzi lwazo. Ngamanzi.I-emulsifier yi-surfactant eneqela le-hydrophilic kunye neqela le-lipophilic kwi-molecule.Ukuze ubonise iimpawu ze-hydrophilic okanye i-lipophilic ye-emulsifier, "ixabiso le-hydrophilic lipophilic equilibrium value (ixabiso le-HLB)" lidla ngokusetyenziswa.Ixabiso eliphantsi le-HLB, lomelela iipropathi ze-lipophilic ze-emulsifier. Ngokuchasene noko, iphezulu ixabiso le-HLB, i-hydrophilicity yomelele.Ukuze ufumane i-emulsions ezinzileyo, i-emulsifiers efanelekileyo kufuneka ikhethwe.
