Title: The Innovations of Makoto Shinohara

Introduction

Makoto Shinohara is a notable inventor based in Ringwood, NJ (US). He has made significant contributions to the field of absorbent materials, particularly in the development of carboxymethyl cellulose absorbents. With a total of 2 patents to his name, Shinohara's work has had a meaningful impact on various applications.

Latest Patents

Shinohara's latest patents focus on the preparation of water-insoluble carboxymethyl cellulose absorbents. The first patent describes a process for creating a substantially water-insoluble, particulate sodium salt of carboxymethyl cellulose. This material is suitable for use in tampons and other catamenial devices. The process involves heating solid, water-soluble sodium carboxymethyl cellulose, which has a degree of substitution of at least 0.4, with carbon dioxide gas. This method effectively insolubilizes the carboxymethyl cellulose, converting it into a form suitable for absorbent applications. The second patent outlines a similar process, where solid, water-soluble sodium carboxymethyl cellulose is treated with hydrogen chloride gas. This treatment, followed by heating, produces a cross-linked, insoluble, partially acid form of carboxymethyl cellulose, also suitable for absorbent applications.
