Kevin Beairsto 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).

  • Aqueous treatment compositions and polymers for use therein
    Patent number: 7964686
    Abstract: Aqueous treatment composition for use as anti-scalant and dispersant. The composition includes a polymer containing low amounts of sulfonate that prove as effective in carbonate and phosphate inhibition as polymers containing much higher amounts of sulfonate.
    Type: Grant
    Filed: April 13, 2007
    Date of Patent: June 21, 2011
    Assignee: Akzo Nobel N.V.
    Inventors: Klein A. Rodrigues, Adrian Zuberbuehler, Stuart Holt, Kevin Beairsto

  • Surfactant composition containing hydrophobically modified polymer
    Patent number: 7183250
    Abstract: The present invention is related to a concentrated surfactant composition containing a hydrophobically modified polymer and/or a hydrotrope. The addition of the polymer or hydrotrope to the concentrated surfactant changes the physical properties of the concentrated surfactant, making it easier to process.
    Type: Grant
