  • Single component hair coloring composition
    Patent number: 7740665
    Abstract: By combining a hydrogen peroxide liberating complex with hair coloring dyes, a highly effective hair coloring composition is obtained which comprises a stable dry powder composition which can be stored in a single container. When use is desired, the stable dry powder composition of the present invention is mixed with water, activating the liberation of hydrogen peroxide and allowing the desired hair coloring effect to be achieved. In addition to providing a single stable dry powder formulation, the composition of the present invention is capable of achieving a wide array of shades and coloring effects.
    Type: Grant
