Abstract

Functionalized cubic gel precursors, functionalized cubic liquid crystalline gels, dispersions of functionalized cubic gel particles, functionalized cubic gel particles, and methods of preparation and use thereof. The precursors, gels, dispersions, and particles are prepared with hydrotropes that do not detrimentally affect the cubic liquid crystalline structure of the precursors, gels, dispersions, and particles. The precursors, gels, dispersions, and particles can be used to deliver active ingredients to substrates.
