摘要：Provided is a method which is capable of producing a cellulose nanofiberdispersion liquid that has a low viscosity and excellent fluidity even at a highconcentration, while exhibiting excellent transparency. In a method for producingcellulose nanofibers, wherein a cellulosic starting material is oxidized in water using anoxidant in the presence of an N-oxyl compound and a compound that is selected fromthe group consisting of a bromide, an iodide and a mixture thereof and the thus obtainedoxidized cellulose is defibrated and dispersed, pulp which is obtained by carrying outkraft cooking after a hydrolysis process is used as the cellulosic starting material.
