Abstract:
Hydrophilic dye is added to oil for providing identification to the oil. The dye is dispersed in the oil in the form of polymolecular particles less than 1 mm. in diameter, for example, as an emulsion. Accordingly, the sample of oil may be exposed to a polar solvent for the dye particles, to cause the dye particles to dissolve in the polar solvent to exhibit an intensified color, when compared with the particles in the oil.
