摘要:
A blackhead-removing face pack sheet with superior ease of use and blackhead-removing capacity is provided. The blackhead-removing face pack sheet 1 is formed from a laminate which comprises a gas-permeable and flexible base layer 2 and a pack material layer 3 the primary component of which is a copolymer of vinyl acetate and N-vinyl-2-pyrrolidone. The base layer 2 comprises a porous material such as a nonwoven fabric, and part of it is impregnated or embedded with the pack material constituting the pack material layer 3. This gives a high force of adhesion between the base layer 2 and the pack material layer 3.
