Abstract

Abstract Wax-base or emollient-base cosmetic compositions may be provided as samples on paper carrying sheets by providing the paper with materials that prevent absorption of oleic materials and providing the cosmetic compositions with a lower sheet that is oleophobic. A binder layer of an oleophilic wax or polymer may be used between said paper and the cosmetic composition. A frangible, thin polymeric film is placed over the cosmetic composition to prevent shear forces and pressure from smearing the composition.
