ABSTRACT
The objective of this paper was to determine the Critical Coalescence Concentration (CCC) of surfactants such as N(dodecyloxycarboxymethyl) N,N,N-(trimethylammonium) bromide (DMGM- 12), N-[2-(dodecyoxycarboxy)ethyl] N,N,N-(trimethylammonium) bromide (DMALM-12) and N-[3- (dodecanoyloxycarboxy)prophyl] N,N,N-(trimethylammonium) bromide (DMPM-11). The surfactants used represent quaternary ammonium compounds containing a hydrophobic moiety with an ester group (commonly known as “esterquats”). The CCC value was determined by analysis of the relationship between concentration of surfactant and average air bubble diameter. The values of the critical coalescence concentration (CCC) were estimated using a graphical method.
