Abstract
W/O or O/W stable dispersions are formed by mixing an oily phase and an aqueous phase when the dispersion is stabilized with cubic gel particles formed by the combination of two amphiphilic compounds, one of the amphiphilic compounds being capable of forming a lamellar phase in the presence of water, and the other being capable of forming an inverse hexagonal phase in the presence of water.
