  • Personal care compositions comprising a zinc containing material in an aqueous surfactant composition
    Patent number: 8119168
    Abstract: Disclosed are compositions comprising an effective amount of a zinc containing material having an aqueous solubility within the composition of less than about 25% by weight at 25° C.; from about 5% to about 50% of a surfactant; and from about 40% to about 95% water; wherein the pH of the composition is greater than about 7. Further disclosed are compositions comprising an effective amount of a zinc containing material having an aqueous solubility within the composition of less than about 25% by weight at 25° C.; from about 5% to about 50% of a surfactant; and from about 0.1% to about 5% of a zinc ionophoric material; from about 40% to about 95% water; and wherein the pH of the composition is greater than about 7.

  • Phase-separated rinse-off hair coloring/conditioning products
    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.
