Abstract
An inert, water-immiscible inert organic liquid having gas transport properties, water and a suitable emulsifying agent are formed into a stable gel by emulsifying a mixture of the same, concentrating the emulsion to form a gel phase and a liquid phase and separating the two phases. The resulting gel can be used as an ointment or cosmetic for skin irritations or wounds, or as a coating in industrial applications where extended contact of a surface with a gas, such as oxygen, is desired. Fluorocarbons or low viscosity silicone oils are suitable organic liquid components of the gels.
