Abstract:Hydroxypropyltrimethyl ammonium chloride chitosan(HACC), a water solube quaternary ammonium salt of chitosan, was prepared by the reaction of chitosan with 2,3 epoxypropyltrimethyl ammonium chloride. The content of quaternary cations(R 4N +) determined by the method of colloid titration with polyanion(PVSK) was 3 39 mmol/g, the content and degree of substitution of R 4N + in N atom were 3 07 mmol/g and 58 1% respectively. IR spectra revealed that the most substituents were attached on N atom of chitosan. The moisture adsorbability of HACC was as good as that of hyaluronic acid(HA), the moisture retentivity of HACC was better than that of HA, the minimum inhibitory concentration(MIC) of HACC for staptytococous aureus (ATCC25293) was 625 mg/L.
Keywords:hydroxypropyltrimethyl ammonium chloride chitosan  preparation  moisture adsorbability  moisture retentivity  antibacterial activity
