Keune So Pure Developer 30 VOL - 1000 ml

The main active ingredient in So Pure Color Developer is Hydrogen Peroxide. Hydrogen Peroxide is formed when water (H2O) picks up an extra oxygen atom (H2O + O = H2O2). The bond is unstable, and the oxygen will easily split off in an alkaline environment. The split-off oxygen develops the color pigments. When So Pure Developer 30 vol. is used, some natural pigments will be fractured. In this way, the hair color is lightened. The higher the volume of Hydrogen Peroxide, the greater the amount of fractured natural Melanin. The Hydrogen Peroxide concentration determines the lightning power.

It has extra stability, so the Hydrogen Peroxide percentage will remain the same, even at high temperatures
