Definition and Examples - ThoughtCo,An emulsion is a type of colloid formed by combining two liquids that normally don't mix. In an emulsion, one liquid contains a dispersion of the other liquid. Common examples of emulsions include egg yolk, butter, and mayonnaise. The process of mixing liquids to form an emulsion is called emulsification.Cold Processing of Emulsions | Emulsion | Phase (Matter),Also. or those for w/o emulsions. plant extract. blending the wax into a warm oil phase in a melt vessel prior to mixing in the cold bulk aqueous phase is an option and only necessitates heating one phase. often receive criticism for their finished texture and appearance and they also play host to a number of microbes and bacteria. flow rate,
