Abstract: With chitosan as starting material,amphipathic O-hydroxypropyl-N-lauroyl chitosan (O-HP-N-LACS) was prepared by orientating modification method.FTIR,1HNMR and XRD were used to characterize the chemical structure of O-HP-N-LACS.The degree of substitution (DS) of O-HP-N-LACS was determined as 20.1% from calculation based upon elemental analysis.Surface activity of O-HP-N-LACS solution as well as the effect of concentration of NaCl and the pH value in the O-HP-N-LACS solution were examined.Meanwhile,foaming performance,including foaming power and foam stability were also examined.Results showed that O-HP-N-LACS displays good surface activity and foaming performance as a polymeric surfactant.

Key words: polymeric surfactant, O-hydroxypropyl-N-lauroyl chitosan, orientating modification, surface activity, foaming performance
