Patent number: 6723160Abstract: Non-thermoplastic starch fibers having no melting point and having apparent peak wet tensile stress greater than about 0.2 MegaPascals (MPa). The fibers can be manufactured from a composition comprising a modified starch and a cross-linking agent. The composition can have a shear viscosity from about 1 Pascal·Seconds to about 80 Pascal·Seconds and an apparent extensional viscosity in the range of from about 150 Pascal·Seconds to about 13,000 Pascal·Seconds. The composition can comprise from about 50% to about 75% by weight of a modified starch; from about 0.1% to about 10% by weight of an aldehyde cross-linking agent; and from about 25% to about 50% by weight of water. Prior to cross-linking, the modified starch can have a weight average molecular weight greater than about 100,000 g/mol.Type: GrantFiled: February 1, 2002Date of Patent: April 20, 2004Assignee: The Procter & Gamble CompanyInventors: Larry Neil Mackey, Gregory Charles Gordon, Lora Lee Buchanan, Stephen Wayne Heinzman, Paul Arlen Forshey

Patent number: 6582509Abstract: The invention relates to a method for preparing an organic pigment from starch, and the pigment thus received. According to the invention, starch granules are swollen to increase their volume and plasticity, their stability towards changes in volume and shape is improved by cross-linking, by derivatization, or by making the surface hydrophobic, after which gas bubbles or cavities are formed inside the granules, these bubbles or cavities having a strong light scattering effect. Generating bubbles or cavities can be performed by evaporating water or another liquid, by releasing impregnated gas, by a gas generating reaction, or by displacing absorbed water with a solvent. The product is useful as a white pigment especially in coating of starch, in paints and in cosmetic products.Type: GrantFiled: April 24, 2002Date of Patent: June 24, 2003Assignee: Aveno OyInventors: Yrjö Mälkki, Reko Lehtilä

Patent number: RE39339Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a fiber-reinforced, starch-bound cellular matrix. Suitable mixtures used to form the articles are prepared by first preparing a viscous preblended mixture comprising water, a gelatinized starch-based binder, and fibers having an average length greater than about 2 mm. The highly viscous preblended mixture effectively transfers the shearing forces of the mixer to the fibers. The final moldable mixture is then prepared by mixing into the preblended mixture the remaining starch-based binder, water, and other desired admixtures, e.g., mold-releasing agents, inorganic filler rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria.Type: GrantFiled: September 2, 1999Date of Patent: October 17, 2006Assignee: E.
