The main active ingredient of ReleasIt is propanol. Most commonly propanol is used as a solvent or it is used to produce other solvents such as antifreezes, lacquer formulations, soaps, dye solutions, window cleaner and more. Compounds of propanol like isopropanol or isopropyl alcohol are most commonly used in the printing industry and in printing ink. ReleasIt is a “detergent” that leaves residue. By contrast, all Procyon products, including Extreme!, contain NO soap, detergents, or any other sticky residue-causing substances. Procyon’s active ingredient is a material used in food processing and municipal water system treatment. It leaves no residue, no VOCs, and is the HEALTHIEST product. Also, you can assure your customers that it is Green Seal Certified! The choice is between Realeasit’s alcohol, or Procyon’s safest, non-toxic formula for your “green” cleaning. Procyon is the REAL, certified “green” choice. Have a great day!
