Isoflavone nanoparticles and use thereof

摘要

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.

主权项

1. An isoflavone nanoparticle composition, comprising an isoflavone, a carbohydrate carrier and optionally water, wherein the isoflavone has an average particle size D[4.3] as determined by laser diffraction technique of less than 3 μm, and wherein the carbohydrate carrier is a hydrophobically modified starch.
