Title: Method of producing cosmetics-impregnated sheet

Abstract: A process for producing a cosmetic-impregnated sheet which comprises applying and infiltrating a cosmetic base to and into a base sheet having on the surface thereof a retentive sheet capable of absorbing and retaining the cosmetic base at a shear rate of 10.sup.2 to 10.sup.6 s.sup.-1, the cosmetic base being applied to and infiltrated into the retentive sheet of the base sheet, and the cosmetic base, when subjected to a steady shear deformation at a shear rate of 2 s.sup.-1 for 100 seconds followed by a steady shear deformation at a stepwise increased shear rate of 20 s.sup.-1, showing no shear stress growth or showing such a shear stress growth that the difference between the peak shear stress B at a shear rate of 20 s.sup.-1 and the equilibrium shear stress A at the same shear rate, B-A, is 20% or smaller of the equilibrium shear stress A in the transition between the two shear rates.
