emulsion: emulsion: [17] An emulsion is an undissolved suspension of tiny drops of one liquid dispersed throughout another. The classic example of this is milk – whence its name. It comes from modern Latin ēmulsiō, a derivative of ēmulgēre ‘drain out, milk out’. This was a compound verb formed from the prefix ex- ‘out’ and mulgēre ‘milk’, a distant relative of English milk. The word’s familiar modern application to paint dates from the 1930s.

emulsion (n.): 1610s, from French émulsion (16c.), from Modern Latin emulsionem (nominative emulsio), noun of action from past participle stem of emulgere "to milk out," from assimilated form of ex- "out" (see ex-) + mulgere "to milk" (see milk (n.)). Milk is a classic instance of an emulsion, drops of one liquid dispersed throughout another.
