<p>The invention concerns compositions containing essentially amorphous cellulose nanofibrils, carboxyl cellulose with a degree of substitution not more than 0.95 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.</p> |
