| abstract |
The present invention relates to compositions comprising essentially amorphous cellulose nanofibrils, at least one additive chosen from carboxycellulose with a degree of substitution of more than 0.95, a natural polysaccharide, a polyol, and optionally at least one co-additive, the content of additive and of optional co-additive being less than or equal to 30% by weight relative to the weight of nanofibrils and of additive and of optional co-additive. Similarly, a subject of the invention is a process for preparing such compositions, which consists in adding the additive and the optional co-additive to a suspension of essentially amorphous nanofibrils, and then in drying the suspension thus supplemented. The compositions obtained are readily redispersable and conserve their initial Theological properties. |
