  • Publication number: 20040158939
    Abstract: Phase-separated rinse-off hair coloring/conditioning compositions comprise water soluble dye materials, conditioning materials, and water, wherein the water soluble dyes are concentrated in a discontinuous phase of liquid emulsion droplets dispersed within the droplets to the extent that the intensity of the color imparted by the dye materials to the droplets is greater than the intensity of the color imparted by the dye materials to continuous aqueous phase. The dispersed phase may be formed by the combination of the conditioning materials and the dye materials. Methods of coloring and conditioning hair are also disclosed.
