COMPOSITION CONTAINING CELLULOSE NANOFIBRILS, THE PREPARATION METHOD THEREOF, AN AQUEOUS SUSPENSION CONTAINING CELLULOSE NANOFIBRILS AND THE USE OF THIS COMPOSITION AND SUSPENSION

摘要

The invention concerns compositions containing essentially amorphous cellulose nanofibrils, carboxyl cellulose with a degree of substitution not more than o.95 as additive, and optionally at least one co-additive, the content in additive and optional co-additive being less than 30 wt. % relative to the weight of nanofibrils and additive and optional co-additive. The invention also concerns a method for preparing such compositions, consisting in adding to a substantially amorphous nanofibril suspension, the additive and optionally the co-additive(s), then in drying the suspension thus additivated. The resulting compositions are easily redispersable and preserve all their rheological properties.
