9 Claims

1. A dry solid of a mixture of an anionically modified cellulose nanofiber and a water soluble polymer, comprising 5 to 300% by mass of the water-soluble polymer relative to the anionically modified cellulose nanofiber, wherein the anionically modified cellulose nanofiber comprises an anion group converted from a hydroxyl group of a glucopyranose ring of the cellulose, or an anion group bonded to a hydroxyl group of a glucopyranose ring of the cellulose via an ether bond or an ester bond,

wherein the water-soluble polymer is a carboxymethyl cellulose or a salt thereof, and

wherein the anionically modified cellulose nanofiber has a fiber width of about 4 to 500 nm, and an aspect ratio of 100 or more.
