RXSOL Demulsifier is a totally organic liquid formulation of surfactants and soluble in toluene, Xylene, Aromatic solvent, crude oil for the demulsification of water in oil and oil in water, capable of performance at room temperature, but with improved speed and percentage of oil removed when applied at temperatures near 60 deg. C (140 deg. F). RXSOL crude oil demulsifier destabilizes the oil-water interface that surrounds each water particle in the emulsion, replaces the emulsifier molecules (if any), and allows the water to coalesce. RXSOL crude oil demulsifier (demulsification of crude oil) is a completely combustible, non-abrasive; non-ash-forming treatment, which will improve the quality of the fuel it, is added to. The effects of crude oil demulsifier in demulsification of water in crude oil emulsions are based on relative rates of water separation were recognized through emulsion breakers.
