Abstract
In this paper is reported the partial hydrophobization of O-(2-sulfoethyl)cellulose (SEC) using 1-bromododecane, 1-bromodecane, and 1-bromododecane with cellulose sulfate (CS), respectively, and characterization of the reaction products by both elemental and spectral analyses. The surface tension, critical micelle concentration (c.m.c.), foaming, emulsifying, detergency and antiredeposition power of the products were also studied. All prepared derivatives reduce the surface tension and exhibit remarkable emulsifying properties. Alkylated SECs were observed to have improved foaming, emulsifying and antiredeposition characteristics compared to the SECs.
