Cubic liquid crystalline compositions and methods for their preparation
Abstract
This invention relates to precursors of cubic liquid crystalline gels, bulk cubic liquid crystalline gels and dispersions of cubic liquid crystalline gel particles and methods for producing them. It is possible to use these precursors, gels and dispersions as enhancers of skin penetrators. These precursors, gels and dispersions are prepared by hydrotope processes which do not adversely affect the cubic liquid crystal structure of the gels and particles.
