Dai-ichi Kogyo Seiyaku to Lecture on TEMPO-Oxidized Cellulose Nanofiber Manufacturing Method

Dai-ichi Kogyo Seiyaku Co., Ltd., headquartered in Kyoto, will present on TEMPO-oxidized cellulose nanofiber (TOCNF) at the "Nanotobi Nanocellulose is Cooking! Understanding CNF characteristics from how to make it" seminar. The seminar is scheduled for April 16, 2026, at the Osaka Central Public Hall. The company's product, LEO CRISTA®, is a TOCNF derived from wood pulp, characterized as a single nanofiber with a width of approximately 3nm. It provides functions such as rheology control, fine particle dispersion, and sedimentation inhibition, with expected contributions to problem-solving in fields like ceramics, batteries, and cosmetics. The lecture will detail the manufacturing process and properties of LEO CRISTA®, which the company states was the world's first practical CNF. Takazumi Tawa from the Core Material Research Department, Sugar & Cellulose Derivative Group, will be the speaker.
