Abstract
Uncoated particles of reversed cubic phase or reversed hexagonal phase material containing an active disposed within are provided. The uncoated particles have an ionic charge that is sufficient to stabilize them in dispersion in a liquid, e.g. a polar solvent. The active that is disposed within the particles may be, for example, a pharmaceutical or nutriceutical compound.
