Product Description	Oil Red EGN is a solvent dye used to color oils, waxes, greases, fats, hydrocarbons derivatives, polishes, and acrylic emulsions. Dyes like Oil Red EGN contain azo-structures and usually produce yellow-red coloration whereas those based on anthraquinones tend to be green-blue. Other examples besides Oil Red EGN include heterocyclic rings, metal complex, pyrazolone, xanthene, and ketoamine. Solvent dyes such as Oil Red EGN do not ionize.
