What does emulsified mean?
Emulsified is the past-tense and past-participle form of the verb emulsify, meaning combined into an emulsion — a stable mixture in which droplets of one liquid are suspended throughout another that they cannot normally dissolve into, most familiar as oil suspended in water. Because oil and water repel each other, achieving this requires agitation and often an emulsifying agent such as egg yolk lecithin, mustard, or a commercial surfactant; once properly emulsified, mayonnaise, hollandaise sauce, milk, and countless cosmetics hold together instead of separating into layers. The word belongs mainly to culinary and scientific language, appearing almost always in the passive voice, since liquids must be made to emulsify by outside action. Figuratively it can suggest anything smoothly blended into a unified whole. Its etymology points back to milk, historically the best-known example of a natural emulsion, giving the term a memorable origin.
verb (past tense and past participle of emulsify)Having been dispersed or suspended as fine droplets of one liquid throughout another liquid into which it would not naturally dissolve, typically with the aid of an emulsifier. It describes the result of combining two immiscible liquids such as oil and water into a stable mixture.
- (of two liquids) Combined into a stable mixture of fine droplets of one suspended in the other, as in cooking or chemistry.
- (figurative) Thoroughly blended or integrated into a smooth whole.
"The vinaigrette was emulsified so thoroughly that the olive oil never separated from the vinegar."
"The chef emulsified butter and stock into a glossy sauce."
"Once fully emulsified, the dressing held together for days without separating."
The word for mixing oil and water literally means "milked" — because milk was the first great emulsion humans ever noticed.

Etymology of emulsified
Emulsified derives from emulsify, formed in English on the model of verbs like liquefy from the noun emulsion, which entered English in the early 17th century from New Latin emulsio. The ultimate source is Latin lac (stem lact-), meaning "milk," via the adjective emulsum literally "milked out." The same Indo-European root gives us lactose, lactic, and related words, reflecting milk's status as the archetypal natural emulsion.

How emulsified is actually used
Chiefly used in technical, culinary, and scientific registers; rare in casual speech except when discussing cooking. Almost always appears in passive constructions (was/is/get emulsified), since liquids do not emulsify themselves.
