Abstract: The present invention relates to methods for processing plant and/or micro-organism derived cellulose materials into rheology/structuring agents. More in particular, the present invention relates to methods wherein plant and/or micro-organism derived cellulose material is co-processed with carboxycellulose. The methods of the present invention provide a variety of benefits, in terms of process efficiency and scalability as well as in relation to the properties of the materials that are obtainable using these methods. For instance, it has been found that (highly) concentrated products produced using the method of the invention are easily (re)dispersible in water and aqueous systems to regain much of the cellulose component's original rheological performance.

Abstract: The present invention relates to compositions comprising fibrillated cellulose and one or more nonionic cellulose ethers. Such compositions were found to be able to modify the rheology of an aqueous medium, also when the aqueous medium comprises salts and surfactants, whereby specific formulations shows desirable thixotropic thickening of the aqueous medium.

Abstract: This invention relates to water-borne acrylic paints and coatings, especially to agents that can be used to reduce the amount of VOC's to yield satisfactory paints or coatings. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to accomplish a reduction in VOCs and at the same time increase hardness and lower cracking of the dried acrylic paints and coatings. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from.

Abstract: This invention relates to an external structuring agent for application in liquid detergent and personal care products. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can advantageously be used to structure liquid detergent and personal care products, providing certain benefits that are much sought after in the design of such products. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. The process of making the structuring agent involves processing under relatively mild conditions, of a biological material that is currently considered a by-product.

Abstract: This invention relates to compositions that have utility, amongst others, in the stabilization of suspension particles or gas bubbles in fluid water-based compositions and/or in conferring shear thinning behavior to such fluid water-based compositions. The inventors have developed parenchymal cellulose based materials, which comprise cell wall derived networks of cellulose based fibers and nanofibrils, can advantageously be used for stabilization of suspended solid particles in fluid water-based compositions. Specific aspects of the invention concern the parenchymal cellulose based materials, their production and their use in fluid water-based compositions, as well as the resulting fluid water-based compositions per se.

Abstract: This invention relates to water-based well drilling fluids. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to produce suspensions having viscosity and rheological properties particularly suitable for use as a drilling fluid. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. Breaking plant-based pulp down into this kind of cellulose based particles involves fewer and gentler processes than to break the pulp down further into cellulose nanofibrils, and therefore the present cellulose based particles can be produced much faster and at lower cost than completely unraveled cellulose nanofibrils.
