<p>A membrane-like material forming component is obtained by dissolving mineral crude oil, bitumen or an amphipathic lipid in a solvent to form a solution thereof, the solvent being selected from the group consisting of halogenated hydrocarbons and p-xylene and being capable of forming in the presence of water and the oil, bitumen or amphipathic lipid and interfacial membrane-like material. Water is then admixed so as to cause the membrane-like material to form and the solution, water and membrane-like material are allowed to separate by relative densities, thereby forming a bottom layer of the solution, a top layer of water and an intermediate layer between the bottom and top layers, the intermediate layer comprising the membrane-like material. The membrane-like material is extended into the top layer of water from which it is isolated. The membrane-like material upon being brought into air dissociates and leaves a component derived from the oil, bitumen or amphipathic lipid and which is active to form or regenerate membrane-like material, when recombined with the solvent and water.</p> |
