Beschreibung
Zusammenfassung:	The invention relates to an aqueous composition for providing at least one barrier property, such as grease, oil and/or water barrier property, for a product comprising cellulosic fibres, and to the use of the composition. The composition comprises α- (1,3→glucan) polymer and at least 0.1 weight-% of alkyl ketene dimer, calculated from dry solids weight of the composition. L'invention concerne une composition aqueuse pour fournir au moins une propriété barrière, telle qu'une propriété barrière aux graisses, à l'huile et/ou à l'eau, pour un produit comprenant des fibres cellulosiques, et l'utilisation de la composition. La composition comprend un polymère α-(1,3-glucane) et au moins 0,1 % en poids de dimère d'alkylcétène, calculé à partir du poids de matières sèches de la composition.
