Abstract
Cubic liquid crystalline gel precursors, bulk cubic liquid crystalline gels, and dispersions of cubic liquid crystalline gel particles, and methods for their preparation, are disclosed. The precursors, gels, and dispersions can be used as skin penetration enhancers. The precursors, gels, and dispersions are prepared by methods employing hydrotropes that do not detrimentally affect the cubic liquid crystalline structure of the gels and particles.
