  • Patent number: 10391041
    Abstract: A sheet-like hair care product including (A) a substrate sheet containing cellulosic fibers and having a bending resistance of 10 to 70 mm measured by the 45° cantilever method in accordance with JIS L1096:2010 and (B) a liquid cosmetic composition. The substrate sheet (A) is impregnated with 1 to 50 g of the liquid cosmetic composition (B). The substrate sheet impregnated with the liquid cosmetic composition is preferably packaged in a packaging container having an access opening with an area of 25 to 4000 mm2 and an openable and closable lid sealing the contents.
    Type: Grant
