  • Patent number: 5733536
    Abstract: The present invention relates to various hair care products containing stable, dispersions of certain high viscosity silicones in certain surfactants; wherein: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, andb. 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.

  • Patent number: 5711936
    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.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, andb. 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.

  • Patent number: 5665374
    Abstract: The present invention relates to unique interdental delivery devices, other than dental floss, which are suitable for cleaning, massaging, and/or treating surfaces of teeth and gums including interproximal and subgingival areas; wherein these devices contain ULTRAMULSION.TM. dispersions of high viscosity silicones dispersed in surfactants, these dispersions are released into the oral cavity from these devices during use wherein the dispersed silicone:a. is insoluble in the surfactant and oriented so as to form coatings in the oral cavity with enhanced substantivity,b. functions as a reservoir for various lipid soluble and/or liquid dispersible ingredients to be released onto oral cavity surfaces, andc. has a particle size from between about 0.1 and about 10 microns with from between about 80% and about 95% of the particles within this range.

  • Patent number: 5151269
    Abstract: A composition for external use contains at least one active ingredient and a capped ethoxylated alcohol of the formula RO(EO).sub.x R.sup.1 where R and R.sup.1 are both hydrocarbon or substituted hydrocarbon and x is at least two. R is preferably a higher alkyl group and R.sup.1 is a lower alkyl group. X is preferably at least 4. The ethoxylated alcohol is typically used in an amount to provide a soothing effect. The ethoxylated alcohol may be incorporated into cosmetic or pharmaceutical compositions such as shaving cream, pre- and after-shave lotions, sunburn lotions, lotions and creams for chapped lips etc., insect bite lotions etc., mouth wash, and anti-perspirant.
