ABSTRACT:

The phenomenon of micellization of non-ionic surfactant Tween 80 has been studied through the influence of additives PVSA in aqueous medium by measuring the cloud points (CP) of the pure surfactant and with PVSA. The CP of pure surfactant Tween 80 found to be declined with increased [Tween-80]. The CP of mixed system shows same trends with increased [PVSA]. The influence of PVSA on the cloud point of Tween-80 is a clear indication that the phenomenon of clouding is associated with the different micelles coalescing. Considering cloud point as threshold temperature of the solubility, the thermodynamic parameters of clouding process (DG0cl , DH0cl and DS0cl ) have been evaluated using
