  • 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.
