<p>The invention concerns compositions containing essentially amorphous cellulose nanofibrils, at least one additive selected among carboxyl cellulose with a degree of substitution higher than 0.95, one natural polysaccharide, one polyol. and optionally at least one co-additive, the content in additive and optional co-additive being not more than wt.30 % 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 an essentially amorphous nanofibril suspension, the additive, the optional co-additive, then in drying the suspension thus additivated. The resulting compositions are easily redispersable and preserve their original rheological properties.</p> |
