Abstract—Two kinds of inlin derivatives, carboxymethyl of carboxymethyl groups into the molecular backbone [3, 4].
inulin (CMI) and quaternized inulin (QI), were essfully Recently, the carboxymethylation of inulin has been very
synthesized. Their structural properties were characterized attractive to researchers developing industrial products with
by FT-IR and their moisture absorption-retention ability specific characteristics: biodegradability, nontoxicity and so
were explored pared with those of hyaluronic acid on [5~9]. Carboxymethyl inulin (CMI) is produced from a
(HA), respectively. Carboxymethyl and quaternary chemical reaction between inulin and monochloroacetic acid
ammonium salt groups are anionic and cationic groups, [10]. Thus, CMI should have improved moisture absorption–
which are both hydrophilic. Thereby, hydrogen bonds readily retention abilities because of its carboxymethyl groups in the
molecule. However, t
