Abstract
Storage stable multiple emulsions of a polar phase A, a nonpolar phase B and a polar phase A, or of a nonpolar phase B, a polar phase A and a nonpolar phase B, employ particulate solids smaller than 1 μm to stabilize the resulting A/B/Aor B/A/Bmultiple emulsions against coalescence, with the proviso that surface-active substances are present only up to a maximum concentration of less than 0.1 times the critical micelle concentration of the surface-active substances in phase A, A, A. The multiple emulsions have numerous uses including controlled release of active substances from a dispersed phase.
