The main active ingredient in Tinta Cream Developer is hydrogen peroxide. Hydrogen Peroxide is formed when water (H2O) picks up an extra oxygen atom (H2O + O = H2O2). The bond is not very stable and the oxygen will easily split off in an alkaline environment. The split-off oxygen atoms develop the color pigments. When Tinta Cream Developer 12%40 vol. is used, some of the natural pigments will be fractured. In this way, the hair color is lightened. The higher the volume of hydrogen peroxide is, the greater the amount of fractured natural melanin. The hydrogen peroxide concentration determines the lightening power
