A method for producing lignocellulose nanofibrils from phosphorylated fibers. The method includes hydrolyzing an amount of phosphorylated fibers in which the phosphorylated fibers include a phosphorylated lignocellulose of Formula I: in which i) lignocellulose is selected from the group consisting of: lignin; hemicelluloses; and cellulose; and ii) n is greater than 0 but less than 8000 mmoles/kg. The phosphorylated fibers are dispersed in an aqueous medium at a first temperature to produce an aqueous dispersion having a consistency. The phosphorylated fibers are dispersed for a predetermined time so as to enhance/increase water accessibility to the fiber wall, thereby causing fiber swelling.

A wrapper paper is described that is suitable for use on aerosol-generating articles and which comprises pulp fibers and one or more polyphosphates, wherein the pulp fibers make up at least 55% and at most 95% of the mass of the wrapper paper and the polyphosphates are together contained in a concentration of at least 5% and at most 30% with respect to the mass of the wrapper paper. In this regard, the polyphosphates are compounds with the molecular formula M.sub.n+2P.sub.nO.sub.3n+1 or M.sub.n[H.sub.2P.sub.nO.sub.3n+1], wherein n is at least 2 and at most 100 and M is a monovalent metal or ammonium (NH.sub.4.sup.+).
