  • Publication number: 20200289343
    Abstract: An absorbent member (4) of the present invention includes fiber clusters (11) containing synthetic fibers (11F) and includes water absorbing fibers (12F), and a plurality of the fiber clusters (11) are interlaced with each other or with the water absorbing fibers (12F). The content mass ratio of the fiber clusters (11) to the water absorbing fibers (12F) (fiber cluster ratio) is smaller in the side of a skin-facing surface (the side of a topsheet (2)) than in the side of a non-skin-facing surface (the side of a backsheet (3)) of the absorbent member (4). The fiber cluster (11) includes a main portion (110) formed by two opposite base surfaces (111) and a body surface (112) intersecting the base surfaces (111).

  • Patent number: 9827175
    Abstract: An oil-in-water emulsion skin cosmetic composition comprising the following components (A), (B), (C), (D) and (E): (A) from 1 to 10% by mass of an oil agent which is liquid at 25° C., (B) from 1 to 6% by mass of an oil agent which is solid or semi-solid at 25° C., (C) from 0.7 to 3.5% by mass of linear alcohol having 12 to 22 carbon atoms, (D) from 0.2 to 1% by mass of at least one selected from the group consisting of an ionic surfactant and a nonionic surfactant having an HLB of 12.5 to 15, and (E) water, wherein the mass ratio of the component (B) to the component (A), (B)/(A), is from 0.3 to 1.0, and emulsion particles have a number-average particle diameter of 1.0 to 3.0 ?m.
