John R. Wittpenn, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Compositions employing nonionic surfactants
    Patent number: 5139705
    Abstract: A mild, non-irritating surfactant composition, which includes an anionic surfactant, an amine oxide, a nonionic surfactant having a relatively low melting point, and a nonionic surfactant having a high melting point relative to the low melting point nonionic surfactant.
    Type: Grant
    Filed: January 25, 1989
    Date of Patent: August 18, 1992
    Inventors: John R. Wittpenn, Jr., 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
