Traditional Dynamic Color inks contain distilled sterile water, pigment & isopropyl alcohol. They do not contain fillers. They may seem thin compared to other brands who use glycerine & other thickeners, but they allow pigment to flow well from the needle packing a ton of pigment.
Dynamic Platinum inks are thicker, do contain glycerine & witch hazel. This line was formulated to meet the EU’s REACH requirements.
