Abstract:
An object of the invention is to provide a material or composition comprising ultrafine cellulose fibers having excellent fluidity. The invention relates to a composition comprising a particulate material comprising ultrafine cellulose fibers and water, and (B) a non-cellulose particulate material in which the water content of the composition is 2 to 94% by mass with respect to the total mass of the composition, and the content of (B) the non-cellulose particulate material is 0.1 to 12% by mass with respect to the total mass of the composition. The invention also relates to a method for producing the composition and a method for producing a material comprising ultrafine cellulose fibers.
