摘要	Quaternary ammonium salt of hyaluronan (QHA), quaternary ammonium salt of starch (QS), and quaternary ammonium salt of chitosan (QCTS) were successfully prepared. Infrared spectroscopy (IR), ¹H NMR and ¹³C NMR techniques were used to characterize the molecular structure of QHA. Results showed that QHA had better moisture absorption abilities than HA both at 43% and 81% RH. QS and QCTS had the same tendency. In addition, the three quaternized polysaccharides had better moisture retention abilities than their corresponding polysaccharides under three humidity conditions: 81% RH, 43% RH and dry condition. The -N⁺ (CH3)3 group played a very important role in moisture-absorption and retention ability of the quaternized polysaccharides. QCTS and QHA showed parallel or better Ra and R h than that of HA, and had potential to use as moisture-retention ingredient, e. g., in cosmetics.
