Patent number: 9028872Abstract: The invention relates to composites comprising a polysaccharide gelled within pores of a foam, methods of preparation, and uses thereof, for example, in biomedical applications such as cell culture media and implants, controlled release delivery systems, food applications, industrial applications, and personal care applications such as cosmetic and oral hygiene. The composites of the present invention are simple to formulate using few steps and are useful for entrapping heat-sensitive components, such as cells, drugs, flavors or fragrances within the polysaccharide gel. In addition, the invention provides for a composite able to gently immobilize fragile components, such as living cells, without exposing such components to shear forces.Type: GrantFiled: March 1, 2007Date of Patent: May 12, 2015Assignee: FMC CorporationInventors: Olav Gaserod, Therese Andersen, Jan Egil Melvik, Michael Dornish, Peter J.

Publication number: 20110294904Abstract: A method for the preparation of microcrystalline cellulose containing tablets by roller compaction followed by tabletting is disclosed. A tablet formulation is converted to a dry granulate by roller compaction, and the dry granulate lubricated dry granulate and compacted to a tablet. The tablet formulation comprises at least one active, an microcrystalline cellulose containing material, and, optionally other pharmaceutically acceptable excipients. The microcrystalline cellulose containing material has a maximum primary compaction tensile strength of at least 9 MPa or at least 9.5 MPa and a secondary compaction tensile strength of at least 5 MPa, at least 5.5 MPa, or at least 6 MPa. A method for evaluating binders is also disclosed.Type: ApplicationFiled: August 10, 2011Publication date: December 1, 2011Applicant: FMC CORPORATIONInventors: Gregory Thoorens, Bruno Leclercq, Brian Carlin, Peter J.
