Title
(EN) USE OF ESSENTIALLY AMORPHOUS CELLULOSE NANOFIBRILS AS EMULSIFYING AND/OR STABILISING AGENT
(FR) UTILISATION DES NANOFIBRILLES DE CELLULOSE ESSENTIELLEMENT AMORPHE COMME AGENT EMULSIFIANT ET/OU STABILISANT
Abstract
(EN)
The invention concerns the use of essentially amorphous cellulose nanofibrils having a crystallinity index not more than 50 % as emulsifying and/or stabilising agent in a dispersion. The nanofibrils can be used in the form of an aqueous suspension, or in dispersible dry form. Said nanofibrils can also be used in combination with at least an additive and optionally at least a co-additive.
(FR)
La présente invention a pour objet l'utilisation de nanofibrilles de cellulose essentiellement amorphe possédant un taux de cristallinité inférieur ou égal à 50 %, comme agent émulsifiant et/ou stabilisant d'une dispersion. Les nanofibrilles peuvent être utilisées sous la forme d'une suspension aqueuse, ou sous la forme sèche dispersable. Les nanofibrilles selon l'invention peuvent également être utilisées en association avec au moins un additif et éventuellement au moins un co-additif.
