👉 Demulsification is a process in which a liquid mixture, usually water, is formed into a solid form. This can be achieved by either adding an aqueous solution or by dissolving it in another substance. In terms of scientific terminology, it refers to the state or condition when two or more substances are mixed together so that they form a single homogeneous mass, such as water and salt dissolved in a solvent or oil and wax dissolved in a petroleum product.
