PURPOSE: A polyurethane composition and a sponge for body exfoliation manufactured therefrom are provided to effectively perform both exfoliation and skin protection by utilizing the function of microcells of polyurethane foam and microparticles of loess simultaneously. CONSTITUTION: The polyurethane composition comprises: 100pts.wt of a hardening agent which comprises 35-95wt% of a mixed polyol where polyether polyol having a molecular weight of 300-2000 and polyester polyol are mixed in a weight ratio of 80-95:5-20, 1-60wt% of loess, 0.1-2wt% of a hardening accelerator, 0.5-5wt% of an amine catalyst, 0.1-5wt% of a pigment, 0.5-15wt% of a foaming agent and 0.5-5wt% of a silicone surfactant; and 100-130pts.wt of polyisocyanate. The sponge for body exfoliation is manufactured by foaming the polyurethane composition to give a block foam, aging the block foam at room temperature for 2-3 days and cutting it into a desired shape.
