Unlike regular mct oil, which separates when mixed with water, emulsified mct oil is water soluble and mixes easily into both hot and cold liquids it also has the added benefit of being.
As an example, oil and water can form, first, an oil-in-water emulsion, wherein the oil is the dispersed phase, and water is the dispersion medium ( lipoproteins , used by all complex. How to remove emulsified oil from wastewater with organoclays search form oil and grease (o&g) are a common occurrence in wastewater an epa commissioned study recently concluded that. An emulsion is a temporarily stable mixture of immiscible fluids, such as oil and water, achieved by finely dividing one phase into very small droplets common emulsions can be oil suspended.
