With a total of 2 patents, her work focuses on enhancing the properties and applications of carboxymethyl cellulose.

Latest Patents

Nishigaya's latest patents include a dispersion composition containing carboxymethyl cellulose. This composition features a water-based medium and a carboxymethyl cellulose with a substitution degree of 0.20 or more, along with a cellulose-I crystallinity index of 50% or more. This formulation allows for easy dispersion even with low mixing power, resulting in a high viscosity. Another notable patent is for carboxymethylated cellulose, which has a carboxymethyl substitution of no more than 0.50 and a cellulose I type crystallization of at least 50%. The ideal specifications for this cellulose include an anionization of 0.00-1.00 meq/g, a Schopper-Riegler freeness of at least 60.0° SR, and a filtration residue ratio of 0%-30% by mass. The viscosity for an aqueous dispersion with a 1% solid content is ideally no more than 10.0 mPa·s.
