Abstract

The effect of incorporation of various organic additives on the solvent power of the different micelles for Carbamazepine was investigated. The variation in the pH value as well as the temperature of these solution on the degree of solubilization of Carbamazepine was also studied.
It was found that propylene glycol increased the solvent power of the different micelles, while glycerol, and PEG 1000, 4000 and 6000 decrease their solubilizing capacity. Raising the temperature and lowering of pH value also increased the solvent power of the micelles.
