The polyurethane gel foams are thereby produced from an isocyanate component A having a functionality f of fB?3, a polymeric polyol component B having a functionality f of fB?6, and a polysaccharide C, comprising at least one uronic acid or a salt thereof, wherein the ratio of the number of isocyanates groups of the isocyananate component A to the total number of hydroxyl groups, carboxy groups and carboxylate groups in the polymeric polyol component B and the polysaccharide C corresponds to the ratio 1:2 to 1:30.Type: ApplicationFiled: October 21, 2009Publication date: August 11, 2011Inventors: Axel Eckstein, Christian Schneider

Patent number: 7838723Abstract: The invention relates to absorbent structures for use in absorbent articles. The structures include a first region for distribution of fluid and a second region for storage of fluid. The first region contains materials, with a relatively high capillary desorption pressure, while the second region contains materials exhibiting a sufficiently high capillary absorption pressure efficiently drain the first region. Exemplary materials have a CSDH 50 of more than 40 cm, and a second region containing a material which satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm (b) an absorption capacity of at least 15 g/g at 0 cm and an absorption efficiency of at least 55% at 40 cm; and (c) a Capillary Sorption Absorption height at 50% of its capacity at 0 cm absorption height (CSAH 50) of at least 35 cm.Type: GrantFiled: March 12, 1999Date of Patent: November 23, 2010Assignee: The Procter & Gamble CompanyInventors: Mattias Schmidt, Gianfranco Palumbo
