Title: FIBROUS CELLULOSE-CONTAINING MATERIAL AND METHOD FOR PRODUCING FIBROUS CELLULOSE-CONTAINING MATERIAL
Abstract:
The present invention addresses the problem of providing a microfibrous cellulose-containing material which has good re-dispersibility and is capable of exhibiting excellent thickening properties after re-dispersion even after a long-term storage. The present invention relates to a fibrous cellulose-containing material which contains fibrous cellulose having a fiber width of 1,000 nm or less and a divalent or higher-valent metal component, and wherein: the content of the fibrous cellulose is 5% by mass or more relative to the total mass of the fibrous cellulose-containing material; the content of the metal component is 0.5% by mass or less relative to the total mass of the fibrous cellulose-containing material; and if the fibrous cellulose-containing material is formed into a slurry having a solid content concentration of 0.5% by mass, the pH of the slurry is 4 or more.
