The use of dyes in the commercialization of fuel is usually associated with protection of the source and destination. It is used as markers to identify and guarantee the identity of the specific product of a particular manufacturer to discourage theft, tampering and disclosure of the quality of solvent or fuel. This work presents a critical analysis on the state of the art about the available analytical methods for identification and quantification of dyes used as markers of solvents and fuels, as well as evaluation of the physical-chemical staining and laws surrounding their use and commercialization.
