  • Method of stabilizing tretinoin
    Patent number: 5037655
    Abstract: A tretinoin-mineral oil-petrolatum product in which the ingredients are blended at about 90.degree. C., which product retains its therapeutic activity despite storage at ambient conditions without the need for an antioxidant.
    Type: Grant
    Filed: April 18, 1990
    Date of Patent: August 6, 1991
    Inventor: Richard L. Giovanoni
  • Surfactant compositions
    Patent number: 5000868
    Abstract: A mild surfactant composition suitable for use on periocular surface tissues includes an anionic surfactant, a nonionic surfactant and an amine oxide. The pH of the composition is substantially at neutrality.
    Type: Grant
    Filed: April 3, 1987
    Date of Patent: March 19, 1991
    Inventors: John R. Wittpenn, Jr., Richard L. Giovanoni

  • Method of cleaning contact lenses
    Patent number: 4814109
    Abstract: The method of cleansing a contact lens adapted to be worn in close proximity to the cornea of the eye and typically having a light coating of mucus, lipids, or other proteinaceous materials on its outer surface, which comprises placing a drop of a mild, nonirritating surfactant composition on the lens while it is being worn to remove said coating from the outer surface thereof, said composition comprising:(a) an anionic surfactant;(b) a nonionic surfactant; and(c) an amine oxide surfactant in an amount capable of enhancing the foaming properties of the anionic and nonionic surfactants while further reducing the irritating characteristics of the anionic surfactant.
    Type: Grant
