  • Methods for preventing crystal growth and particle aggregation in nanoparticulate compositions
    Patent number: 6267989
    Abstract: The present invention is directed to methods for preventing crystal growth and particle aggregation in nanoparticulate compositions. The methods comprise reducing a nanoparticulate composition to an optimal effective average particle size. The resultant nanoparticulate compositions exhibit prolonged particle size stability and minimal crystal growth, even following exposure to elevated temperatures.
