Let’s understand the chemical structure and importance of solvent colorants

Solvent dyes, as the name suggests these are non-polar in nature and have the solubility in organic solvents. This agent is used in wider application area.

For coloring material like waxes, ink, organic solvents, plastic materials, hydrocarbon fuels etc., the use of these dyes is immense. Its feature to color hydrocarbon-based nonpolar materials makes it the best dyes amongst coloring agents. It is also referred as solvent red, solvent yellow, green, and blue.

Apart from coloring agent, this is also termed as liquefying agent because of its feature that enables it to liquefy in other chemicals.

Another feature of solvent dye that sets it apart from rest of the others is its insolubility in water. This means the dye is mixed with water for obtaining results but it does not completely resolves into it. This formation of mixing of dye into water forms a separate layer of residuals.

The solubility feature of solvent dyes helps achieving fine and long lasting color shades, which is not present in any other coloring agent.

Moreover this coloring agent do not ionize, which means, solvent dyes are required going through molecular reorganization and lost their ability to ionize. During the process of ionization the polarity of chemical compound changes. This is because releasing or adding an electron during chemical reaction causes the polarity of chemical substance to change. Hence, this is the reason why these colorants are not soluble in water and falls into the category of high-polar substances.

The feature makes these solvent colorants optimal for making perfumed items. Besides this, these also easily react with non-polar chemicals such as oils, fuels, fats etc.

Following is detailed discussion about the areas in which solvent colorants are used-
  • Petrol & Fuel Oils
  • Cosmetics
  • Preparing wax & candles
  • Removing wood stain, and varnishes
  • Coating and copying papers
  • Coating typewriter ribbons
  • Rubber stereo printing
  • Color molding powders, PVC, P/F, U/F, PMMA, PETP, and styrene monomers
    Dye leather
  • Used in preparing aluminum foil printing, cellulose acetate, alkyd, nitrocellulose etc.
From the above stated points, you must have gained knowledge about the structure and use of dyes. If you are dealing in any of the industries that you must be requiring this dye. For purchasing it, you must contact a reliable chemical provider in the industry. The term reliable means one who is known for providing quality products.
