Abstract

Hydroxypropyl cellulose, a semi-synthetic organic compound, is classified into high substitution and low substitution variants. Both display distinct physical and chemical traits, making them prevalent in a plethora of industries, including the pharmaceutical, daily chemical, construction, food and many others. For most efficient use of hydroxypropyl cellulose, it is crucial to comprehend and enhance its properties. For this reason, research in the field of hydroxypropyl cellulose modification has become a focal point. This paper provides a comprehensive review of the modification methods of hydroxypropyl cellulose and presents the current state of research in the field of hydroxypropyl cellulose modification, which has important reference value for practical application.
