Seiko PMC Co., Ltd.
Notice Regarding Acquisition of Shares of Marine Nanofiber Co., Ltd. (Making it a Subsidiary)
Toward expansion of business portfolio centered on nanofiber technology
We would like to inform you that we have resolved to acquire a majority of the outstanding shares of Marine Nanofiber Co., Ltd. (hereinafter “Marine Nanofiber”) and make it a subsidiary.
Reason for stock acquisition
Marine Nanofiber ( is a
university-originated venture company established in April 2016 by Professor Shinsuke Ifuku of Tottori University, an authority on chitin nanofiber research. . Chitin nanofibers are made from chitin, which is the main component of shells of crustaceans such as crabs and shrimps and the cell walls of mushrooms, and its hydrolysates, and are made into nano-level ultrafine fibers using a special processing method developed by Professor Ifuku. It is a new material. In addition to being highly dispersible in water, chitin nanofibers have been shown to have various physiological effects such as high moisture retention, film-forming ability, and anti-inflammatory effects. Currently, the company is actively developing its business mainly in the healthcare field, such as cosmetics and pet care products, by making use of these functions.

We are promoting the expansion of our business that makes full use of environmentally friendly technologies under the management vision of “Creating the future with eco-technology”. Among them, the use of natural materials is positioned as an important theme, and in recent years, we have been focusing on the development of “cellulose nanofibers”, which are fibrillated to the nano level from cellulose derived from wood. Chitin nanofiber is a sustainable material that makes effective use of natural materials such as crab shells and shrimp shells that would normally be discarded.
Since chitin and cellulose have very similar skeletons, the
development of chitin nanofibers and cellulose nanofibers have many technical similarities. On the other hand, in terms of function, there is a characteristic difference in performance derived from the difference between chitin and cellulose. It is possible to develop applications that take advantage of the limited. In the future, we will promote further expansion of our business portfolio centered on nanofiber technology by promoting mutual utilization of technologies and networks in the industrial field, which is our specialty, and the healthcare field, which is our specialty. .
