  • Method to assess surfactant adsorption on skin
    Patent number: 7749487
    Abstract: A convenient to use test method for comparing the relative affinity of surfactants for the skin employs a solid or semisolid matrix for associating a dye or pigment with the skin. The dye or pigment has an affinity to either the skin or a surfactant adsorbed on the skin during personal cleansing. The matrix may include a reagent soluble polymer film or temporary tattoo.
