          solution constitutes a normal and necessary method of putting up these products           
          adopted solely for reasons of safety or for transport and that the solvent does           
          not render the product particularly suitable for a specific use rather than for           
          general use;

          agent or a coloring substance added to facilitate their identification or for safety      
          reasons, provided that the additions do not render the product particularly               
          suitable for a specific use rather than for general use.
