Organic nanoparticles obtained from microemulsions by solvent evaporation.


The invention provides a redispersible powder and aq. dispersions comprising nanoparticles of water insol. org. compds. The invention further provides methods for prepg. the redispersible powder and the aq. dispersion, wherein the methods comprise prepn. of an oil-in-water microemulsion and solvent removal. Thus, an oil-in-water microemulsion was prepd. contg. sodium dodecyl sulfate (SDS) 8 %, Bu acetate 3.5 %, 2-propanol 3.5 %, water 82 % and Pr paraben 3 %. [on SciFinder(R)]
