Mbali iliyonse imagwirizana ndi madzi ndi mafuta. Mamolekyu a surfactant amasonkhana pa mafuta‑mawonekedwe a madzi, ndipo zimenezo zimapanga maziko oyambira. Emulsification ndi imodzi mwa ntchito za ma surfactants, koma ndiyo yofala kwambiri‑ntchito yomwe imagwiritsidwa ntchito m'makampani athu.

Kugwira ntchito kwa emulsifier kumadalira pa kulinganiza bwino. Mphamvu zake zokonda madzi ndi mafuta zimapangitsa kuti zikhale ngati ming'alu.
