Abstract: A process and composition for coloring human hair on the head with pigments that employ a dispersion of pigment or pigments in an aqueous alcoholic liquid medium that contains a cationic polymer that is compatible with the aqueous alcoholic medium.

Abstract: The specific embodiments provide a razor blade comprising at least one cutting edge, and an adherent fluorocarbon polymer coating on the cutting edge. The coating has microscopic raised portions. There is also provided a method of treating a razor blade comprising depositing on the cutting edge of the blade a composition comprising a first fluorocarbon polymer and a second fluorocarbon polymer having a molecular weight greater than the first polymer. The deposited composition is heated at a temperature sufficient to cause the first polymer to melt and flow and insufficient to cause the second polymer to melt and flow. Alternatively, the molecular weights of the two polymers are chosen to be sufficiently different such that when the two polymers melt during a heating step the viscosity of the high molecular weight second polymer is sufficiently high to avoid or at least minimize flow.
