Emulsifier ndi mtundu wazinthu zomwe zimatha kupanga chisakanizo cha zigawo ziwiri kapena zingapo zosasinthika kukhala emulsion yokhazikika. Mfundo yake yochitapo kanthu ndi njira ya emulsion, gawo lomwazika mu mawonekedwe a madontho (microns) omwazika mu gawo lopitilira. amachepetsa kukangana interfacial wa chigawo chilichonse mu dongosolo wosanganiza, ndi dontho pamwamba kupanga filimu olimba kapena chifukwa cha mlandu wa emulsifier waperekedwa mu droplet pamwamba mapangidwe magetsi awiri wosanjikiza, kuteteza m'malovu kusonkhanitsa wina ndi mzake, ndi kukhalabe yunifolomu. emulsion.Kuchokera ku gawo la maganizo, emulsion akadali heterogeneous.The obalalika gawo mu emulsion kungakhale madzi gawo kapena mafuta gawo, ambiri amene ndi mafuta gawo.The mosalekeza gawo akhoza mwina mafuta kapena madzi, ndipo ambiri a iwo. ndi madzi.An emulsifier ndi surfactant ndi gulu la hydrophilic ndi gulu la lipophilic mu molekyulu.Kuti afotokoze za hydrophilic kapena lipophilic properties za emulsifier, "hydrophilic lipophilic equilibrium value (HLB value)" nthawi zambiri amagwiritsidwa ntchito.Kutsika kwa mtengo wa HLB, mphamvu ya lipophilic ya emulsifier. M'malo mwake, mtengo wa HLB wapamwamba, umakhala wamphamvu kwambiri wa hydrophilicity.Ma emulsifiers osiyanasiyana ali ndi makhalidwe osiyanasiyana a HLB.Kuti mupeze ma emulsions okhazikika, ma emulsifiers oyenera ayenera kusankhidwa.
