Abstract
The present invention relates to various ingestible products containing stable, dispersions of certain high viscosity silicones in certain surfactants for use in treating mucus containing surfaces such as in the mouth, throat and stomach and intestine and the surface of the esophagus which contains no mucus. PA1 a. the dispersed silicones, which are insoluble in said surfactant, are oriented by the surfactant such that when dispersed in water they are particularly adept at forming oriented coatings on mouth, throat and esophagus and stomach surfaces with enhanced substantivity, and PA1 b. the particle size of the dispersed silicone is from between about 0.1 and about 10 microns, with a particle size distribution such that from substantially all of the dispersed silicone is within this particle size range. These stable dispersions are described as ULTRAMULSION.TM. dispersions, which, together with their physical properties, when contained in mouth, throat, esophagus, stomach and intestine treatment properties, when contained in products, provide these products with substantive coating protection properties where the discontinuous silicone phase of said coating functions as a reservo…
