  • Dry spreadable water dispersible granule compositions
    Patent number: 5759943
    Abstract: This invention relates to activated charcoal granule compositions which can be dry spread and "watered-in" to a site to reduce undesirable biological activity of deleterious organic compounds. When wet, these granules disperse very rapidly with a large dispersion area to original granule diameter ratio. The granules have high loadings of charcoal, i.e., from about 60 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent dispersing; rewetting; and binding properties.
    Type: Grant
    Filed: May 22, 1996
    Date of Patent: June 2, 1998
    Assignee: Rhone-Poulenc Inc.
    Inventors: Mark David Einziger, Edward G. Fu, Alan Joseph Stern, Stanley John Kostka, Patrick Michael Holroyd
