Several surfactants (nonionic, anionic, and cationic) have been tried to overcome the limitations of CUR. Studies suggest that the incorporation of CUR in micellar media plays a significant role in improving the solubility and stability of CUR. The choice of surfactant depends on the critical micelle concentration and the degree to which the CUR partitions into the micelles. Further, CUR-surfactant interactions can be brought about by various techniques, viz., microencapsulation, solid dispersion, and nanoemulsions.
