  • Colloidal microcrystalline cellulose compositions, their preparation and products
    Patent number: 11097008
    Abstract: The present invention is directed colloidal microcrystalline compositions, particularly for suspending particles in low viscosity fluids, produced by co-attrition of a mixture of microcrystalline cellulose and at least a polysaccharide in the presence of acidic attrition aid; their preparation; and, products made therewith.
    Type: Grant
    Filed: June 20, 2018
    Date of Patent: August 24, 2021

  • Method of making bleached microcrystalline cellulose
    Patent number: 10597820
    Abstract: A method of producing bleached microcrystalline cellulose which method comprises neutralizing or alkalizing an acidic microcrystalline production reaction mixture slurry, typically produced by acid hydrolysis or by electronic beam irradiation, followed by adding an oxidant to such reaction mixture. This practice of this method permits the production of microcrystalline cellulose having desirable color stability as well as compression characteristics suitable for pharmaceutical binder use from paper grade and other low purity pulps.
    Type: Grant
