Silicon Dioxide Containing Patents (Class 424/724)
  • Patent number: 5607667
    Abstract: The effectiveness and/or hydrating ability of body care compositions, such as moisturizers, skin creams, body lotions, shampoo, hair conditioner, styling gel, styling mist, hair dye, bath additives, pedicure and manicure products, facial cleanser, facial mist, suntan lotions, and sunscreen lotions, are enhanced by the addition thereto of an aqueous suspension containing small concentrations of colloidal silica. The colloidal silica particles are charged and of a size between about 10 angstroms and 100 angstroms. An aqueous solution of colloidal silica particles is prepared by circulating the solution through a magnetic field so that the particles cut the field flux lines and build up a net negative charge thereon. It is preferred that the solution be passed through a magnetic void after passing through a magnetic field to allow the particles to configure themselves without the influence of external magnetic fields.

  • Patent number: 5599531
    Abstract: The penetration or absorption of water, oils, collagen, and other materials into the hair is greatly increased by adding a small quantity of inorganic charged colloidal silica to provide an aqueous suspension of the charged colloidal silica particles along with the material to be absorbed into the hair. In coloring hair, dye components can be absorbed into the hair without the use of alkaline solutions which damage the hair, and in perming hair, the disulfide bonds in the hair can be broken by tension caused by swelling due to water absorption in the hair, again without the use of damaging alkaline solutions. It is believed that the porosity and stable hydration of the hair can be varied through altering the electrostatic charge on the hair. The aqueous suspension of charged silica particles applied to the hair appears to alter this charge.

    Abstract: Titanium oxide particles comprising particulate titanium oxide substrate having a zinc oxy compound or a combination of a zinc oxy compound and a silicon oxy compound supported thereon. They can be produced by adding a zinc compound or a combination of a zinc compound and a silicon compound together with an alkali to a dispersion of particulate titanium oxide substrate to neutralize the zinc compound or the combination of the zinc compound and the silicon compound in said dispersion, then separating and drying the resultant product. They are useful for pigments, catalysts, catalyst supports and adsorbents, and particularly excellent in deodorizing performance by removing malodorous gases such as ammonia, methyl mercaptan, hydrogen sulfide, trimethylamine, methyl sulfide and acetaldehyde through decomposition and adsorption thereof, so that they are useful as white deodorants for sanitary objects such as paper diaper and sanitary napkins which come to directly contact with the skins of human beings.

    Abstract: Silicic acid modulates (i.e. enhances or inhibits) adenylate cycloase activity. This effect appears to be a general one, inasmuch as the modulation has occurred in all tissues studied. The results suggest that silicic acid can be used in human and veterinary medicine to modulate hormone or neurotransmitter response. The results also indicate that silicic acid can be used to prevent, treat, or delay the onset of calcium-related bone disease, or to improve bone strength in an vertebrate having a bone strength less than desired.
