  • Isoflavone nanoparticles and use thereof
    Patent number: 8951560
    Abstract: The present invention is directed to isoflavone nanoparticle compositions comprising isoflavone in the form of nanoparticles and preferably a carrier. The isoflavone nanoparticle compositions are particularly useful for preparing cosmetic compositions, pharmaceutical compositions, foodstuff, food and feed additives. In the compositions comprising the isoflavone nanoparticle compositions recrystallization of the isoflavone to bigger particles is retarded.
    Type: Grant
    Filed: January 31, 2006
    Date of Patent: February 10, 2015
    Assignee: DSM IP Assets B.V.
    Inventors: Juergen H. Vollhardt, Philippe Emmanuel Maillan, Raphael Beumer, Chyi-Cheng Chen, Heinz Gutzwiller, Ernst Zedi
  • Topical compositions comprising nanoparticles of an isoflavone
    Patent number: 8685456
    Abstract: The present invention is directed to topical compositions, comprising isoflavone nanoparticle compositions. The isoflavone nanoparticle compositions contain isoflavone in the form of nanoparticles and preferably a carrier. In the topical compositions recrystallization of the isoflavone to bigger particles is avoided.

    Date of Patent: April 1, 2014
    Assignee: DSM IP Assets B.V.
    Inventors: Raphael Beumer, Chyi-Cheng Chen, Heinz Gutzwiller, Philippe Emmanuel Maillan, Markus Nowotny, Bernd Schlegel, Juergen H. Vollhardt
  • Composition comprising an HDAC inhibitor in combination with a retinoid
    Publication number: 20100286278
    Abstract: The present invention is directed to compositions which contain a combination of at least one histone deacetylase inhibitor (HDAC inhibitor) and a retinoid. The composition is in particular a cosmetic preparation. It was found that the combination of an HDAC inhibitor and retinol or a derivative thereof is in particular useful for treating wrinkles but also for thickening the epidermis and for improving hair growth.
