CELLULOSE-BASED BIODEGRADABLE POLYMERIC SURFACTANTS

In this paper is reported the partial hydrophobization of O-(2-sulfoet hyl)cellulose (SEC) using 1-bromododecane, 1-bromodecane, and 1-bromod odecane with cellulose sulfate (CS), respectively, and characterizatio n of the reaction products by both elemental and spectral analyses. Th e surface tension, critical micelle concentration (c.m.c.), foaming, e mulsifying 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 observe d to have improved foaming, emulsifying and antiredeposition character istics compared to the SECs.
