    摘要: The present invention provides a foamable composition for administration to the skin, body surface, body cavity or mucosal surface, e.g., the mucosa of the nose, mouth, eye, ear, respiratory system, vagina or rectum. The foamable oil in water nano emulsion composition includes: (a) a nano oil globule system, comprising substantially of sub-micron oil globules; (b) about 0.1% to about 5% by weight of at least one stabilizing agent, selected from the group consisting of (i) a non-ionic surfactant, (ii) an ionic surfactant, and (iii) a polymeric agent; and (c) a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition, water and optional ingredients are added to complete the total mass to 100%. Upon release from an aerosol container, the foamable composition forms and expanded foam suitable for topical administration. The present invention further provides methods of treating, alleviating or preventing a disorder of the skin, body cavity or mucosal surface using such foamable compositions; and to methods of producing such foams having an improved bubble size.
