  • Removal of colored substances from aqueous liquids
    Patent number: 9161868
    Abstract: The use of a decolorizing composition for removing colored substances from aqueous fluids (e.g., colored pigments, blood-containing fluids, etc.) is provided. The decolorizing composition contains one or more inorganic salts. In one embodiment, for example, the composition contains a mixture of sodium sulfate (Na2SO4) and monopotassium phosphate (KH2PO4). The decolorizing composition may be placed in fluid communication with an absorbent core, a liquid-permeable layer, or combinations thereof, in an absorbent article to help decolorize blood-containing fluids (e.g., menses) exuded from the body.
    Type: Grant
    Filed: August 31, 2010
    Date of Patent: October 20, 2015
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Francesca Corbellini, Eckhard Purkner, Elisabeth Baumgarten, Hans Bouten, Arndt Scheidgen, Franz Aschenbrenner, Doohong Kim, Priscilla Eng Choo Goh

  • Coextrudable hot-melt adhesive
    Patent number: 8076422
    Abstract: A hot-melt adhesive for resealable packaging, containing 30 to 90 wt. % of at least one copolymer based on ethylene and/or propylene together with C4 to C12-?-olefins, which is obtainable by metallocene-catalyzed polymerization, with a melt index of 5 to 100 g/10 min (DIN ISO 1133), 5 to 50 wt. % of tackifier resins with a softening point of 80 to 140° C., 0 to 15 wt. % of waxes with a melting point of 120 to 170° C., 0.1 to 20 wt. % of additives and auxiliaries, the adhesive having a viscosity of 25,000 mPa·s to 250,000 mPa·s, measured at a temperature of 170 to 190° C.
