<p>The invention relates to organic nanopowders and methods for their produc tion, including ascorbic acid nanoparticles and nanopowder salts of ascorbic acid, such as, calcium ascorbate nanopowders. Such organic nanopowders may have utility in cosmetics, pharmaceutical preparations and nutrition. The in vention additionally relates to methods for producing ascorbic acid nanopart icles and calcium ascorbate nanopowders. The method of preparation of ascorb ic acid or calcium ascorbate nanopowders involves: (i) preparing an solution including an organic compound solute and a solvent to disperse or dissolve the organic compound, and (ii) removal or separation of the solvent in such a manner so as to limit the growth of the organic solute particles to nanome ter range which is typically below 500 nm but preferably 100 nm or less.</SD OAB></p> |
