Abstract
Methods for manufacturing, re-activating and using compositions including fibrillated parenchymal cellulose and activator are provided. The activator has a low molecular weight and is used to facilitate reactivation.
Claims22
A composition comprising fibrillated parenchymal cellulose, at least one liquid activator, and optionally water.
A re-activated composition obtainable by a method comprising
- a. Mixing a dry product of fibrillated parenchymal cellulose, at least one liquid activator, and optionally water processed into a powder-like substance or granules having a Carr index value below 40 or a Hausner ratio below 1.6 or a refined composition of fibrillated parenchymal cellulose, at least one liquid activator, at least one additional substance of an oily substance or a non-water miscible oil and optionally water with water or an aqueous medium to obtain a mixture;
- b. Hydrating the mixture up to 1 day to obtain a hydrated mixture;
- and
- c. Mixing the hydrated mixture until re-activated.
A re-activated composition obtainable by a method comprising
- a. Mixing a dry product of fibrillated parenchymal cellulose, at least one liquid activator, and optionally water processed into a powder-like substance or granules having a Carr index value below 40 or a Hausner ratio below 1.6 or a refined composition of fibrillated parenchymal cellulose, at least one liquid activator, at least one additional substance an oily substance or a non-water miscible oil and optionally water with resin, monomer, or molten polymer to obtain a premixture;
- b. Mixing said premixture up to 1 day;
- until re-activated.
A use of a composition comprising fibrillated parenchymal cellulose, at least one liquid activator, and optionally water, a re-activated composition or product including the composition or the reactivated composition as an additive or component for modifying one or more of:
- viscosity, mechanical properties, strength, stiffness, toughness, binding properties, suspension stability, gel insensitivity to temperature, material insensitivity to temperature, shear reversible gelation, yield stress, and liquid retention of the composition of matter, the re-activated composition obtainable by a method comprising
- a. Mixing a dry product of fibrillated parenchymal cellulose, at least one liquid activator, and optionally water processed into a powder-like substance or granules having a Carr index value below 40 or a Hausner ratio below 1.6 or a refined composition of fibrillated parenchymal cellulose, at least one liquid activator, at least one additional substance of an oily substance or a non-water miscible oil and optionally water with water or an aqueous medium to obtain a mixture;
- b. Hydrating the mixture up to 1 day to obtain a hydrated mixture;
- and
- c. Mixing the hydrated mixture until re-activated.
