Synthesis and characterization of chitosan ethers: Hydroxypropyl chitosan and Hydroxyethyl chitosan

open access: yesMANAS Journal of Engineering
The hydroxypropyl chitosan (HPCH) and hydroxyethyl chitosan (HECH) are multifunctional chitosan derivatives with biocompatible and biodegradable properties. Due to their hydroxypropyl and hydroxethyl groups, they have water solubility, moisture retention, and gelling properties. In this study, the chitosan derivatives HPCH and HECH were obtained in two
