... cleaning depends on the physical action of emulsification, in which discrete particles of contaminant are suspended in the cleaning medium and then separated from the surface to be cleaned. Emulsion cleaners can be water or water solvent-based solutions; for example, emulsions of hydrocarbon solvents...

... in the liquid, continuous phase. An unstable single-phase emulsion has a uniformly dispersed phase that tends to separate and form a solvent layer. Solvents with specific gravities less than 1.0 form top layers, and those with specific gravities greater than 1.0 form bottom layers. These cleaners require...
