CARBOXYMETHYLATED CELLULOSE NANOFIBERS AND PRODUCTION METHOD THEREFOR

WIPO Patent Application WO/2018/194049

A1

Provided are: carboxymethylated cellulose nanofibers which provide a liquid dispersion having low viscosity; and a production method for the carboxymethylated cellulose nanofibers. This production method for carboxymethylated cellulose nanofibers comprises (A) a step for preparing carboxymethylated cellulose, (B) a step for treating the carboxymethylated cellulose using hydrogen peroxide, and (C) after the treatment, a step for defibrating the carboxymethylated cellulose to obtain cellulose nanofibers. The carboxymethylated cellulose nanofibers according to the present invention have a cellulose crystal I-type content of 55-65%, wherein an aqueous dispersion containing 1.0% (w/v) of the carboxymethylated cellulose nanofibers has a B-type viscosity of 500 mPa·s or less.
