'''Emulsija''' – dviejų nesimaišančių [[skystis|skysčių]] [[dispersinė sistema]]. Pvz., [[sviestas|svieste]] [[vanduo|vandens]] lašelius supa riebalai, o piene vandeninis tirpalas supa riebalų lašelius. Emulsijos gaunamos emulsavimo pagalba. Emulsijos nėra stabilios, todėl joms gauti reikalinga energija (kratymas, maišymas, kt.). Po kurio laiko emulsijos vėl savaime išsisluoksniuoja į riebiąją ir vandens fazę. |

[[Paviršinio aktyvumo medžiagos]] (surfaktantai) gali labai padidinti emulsijų kinetinį stabilumą, tada jos net ilgai laikomos, mažai pakinta. Surfaktantai skirstomi į: |

Į ką virs emulsija – į vandens emulsiją aliejuje ar aliejaus emulsiją vandenyje - lemia dviejų fazių skysčių santykis ir naudojami [[emulsiklis|emulsikliai]]. Dažniausiai galima pritaikyti Bancroft'o taisyklę: emulsikliai skatina tos fazės dispersiją, kurioje jie prasčiau ištirpsta; pvz., baltymai geriau ištirpsta vandenyje nei aliejuje, todėl skatina susidaryti aliejaus emulsiją vandenyje, nes palengvina aliejaus lašelių dispersiją vandens fazėje. |
