Abstract
These materials having the appearance and the consistency of gels are characterized in that they contain a very high proportion of water, of the order of from 60 to 98% weight, and that their structure is a microcellular compartmentalized structure having a very high density of water droplets enclosed in a fine surfactant membrane and contained in a continuous oil/surfactant phase, this structure being impermeable to water and permeable to hydrophobic compounds soluble in fluorocarbons. Use in the field of optics, fillers, cosmetics, pharmacology, lubricants, textiles, photochemistry and electrodynamics.
