The flexible spacer may comprise a polyalkyleneglycol with a molecular weight from about 400 to 10,000. The coupling groups may be provided by divinyl sulphone units.Type: GrantFiled: March 9, 2001Date of Patent: July 4, 2006Assignee: SCA Hygiene Products ABInventors: Guiseppe Mensitieri, Fabrizio Porro, Luigi Nicolais, Alessandro Sannino

Patent number: 6921819Abstract: The invention relates to a process for the crosslinking of polysaccharides. The process of the invention is a process for the crosslinking of at least one polymer selected from polysaccharides and their derivatives, under the action of at least one polyfunctional crosslinking agent, characterized in that said polyfunctional crosslinking agent is reacted with said polymer, in the solid state, during hydration. The invention is applied to the manufacture of hydrogels and gels that can be used, in particular, in plastic or cosmetic surgery.Type: GrantFiled: July 16, 2001Date of Patent: July 26, 2005Assignee: Laboratoires d'Esthetique AppliqueeInventors: Estelle Piron, Raymonde Tholin

Patent number: 6846497Abstract: This invention relates to a starch based tablet disintegrant useful at low addition levels and providing equally effective properties in water and physiological fluids. The starches are characterized by their low solubility in cold water, high swelling power and labile birefringence in the dry state, which rapidly disappears upon addition of water. The preferred starches are inhibited then processed to remove a portion of the granular structure.Type: GrantFiled: January 30, 2003Date of Patent: January 25, 2005Assignee: National Starch and Chemical Investment Holding CorporationInventors: Monika K. Okoniewska, James J. Kasica, Eric M. Weisser

Patent number: 6843888Abstract: This invention relates to a degraded, inhibited cationic starch for use in papermaking systems, which affords improved physical properties, particularly strength. Additionally these derivatives provide easy-to-prepare alternatives totraditional starches, and can even be added directly to the papermaking process without cooking. While the benefits of these starch compositions can be applied to any type of papermaking method, they are especially useful in high shear, high conductivity and recycle systems.Type: GrantFiled: March 13, 2001Date of Patent: January 18, 2005Assignee: National Starch and Chemical Investment Holding CorporationInventors: Michele M. Merrette, John J. Tsai, Paul H. Richardson

Patent number: RE44519Abstract: Starch compositions, including cationic crosslinked starches, and methods of using those starches in papermaking are disclosed. In particular, a cationized crosslinked starch and use of the starch in the wet end system of a paper machine is disclosed. The starch compositions of the disclosure are particularly adapted for customization for specific wet end systems, and allow for modification to correspond to variations in the wet end of the papermaking machine.Type: GrantFiled: February 24, 2005Date of Patent: October 8, 2013Assignee: Cargill, IncorporatedInventors: Kevin Ray Anderson, David Edward Garlie
