Solvent Blue 35

Description

Solvent Blue 35 (SB 35) is commercially available under various names: Sudan Blue II, Oil Blue 35, Blue 2N, Blue B and Oil Blue B. EU member states distinguish natural gas oil by using national dyes. In France, marine diesel is dyed blue with solvent blue 35; In Croatia, SB-35 is used to dye diesel fuel. The blue dye SB35 is added to the diesel and the color changes from light yellow to green/blue[1].
