Abstract
Abstract A quick-drying pack-type face-cleansing composition comprises sebum-absorbing powder, water-repellant powder, a non-ionic surfactant having an HLB of 12-18, and water. The sebum-absorbing powder may preferably be powder of bentonite, kaolin, talc, organobentonite, sericite, mica, silica, silicates, zeolite, diatomaceous earth, barium sulfate, calcium carbonate, polyvinyl chloride, polypropylene, polymethyl methacrylate, a polymer of an acrylic acid derivative, nylon, or polystyrene.
