Our solvent dyes are insoluble in water but soluble in organic solvents and plastic. In other words, the chemicals which easily dissolve in other chemicals forming solution are solvent dyes. They are also oil dyes which are soluble in oil preparing oil-soluble dyes. Some of the typical solvents are ketones, ethers, alcohols, fats, oils, wax, aromatic hydrocarbons and chlorinated hydrocarbons. They directly used in the coloration of product. The molecules of these solvent are non-polar that do not easily undergo ionization.
