Abstract
The present invention relates to various hair care products containing stable, dispersions of certain high viscosity silicones in certain surfactants; wherein: 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 hair 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 hair care products, provide these hair care products with distinctive conditioning, moisturizing, protecting, etc. properties where the discontinuous silicone phase functions as a reservoir for various hair treatment substances.
