ABSTRACT:
A water-dispersible condensate of water-insoluble ultrafine particles of medicine or hormones having a particle size of at largest 4 .mu.m prepared by the steps of heating the medicine or hormone in a vacuum vessel at a temperature of 30.degree. C. higher than the boiling point and at a pressure between 0.01 Torr and 10 Torr to evaporate the medicine or hormone and condensing the medicine or hormone on a recovery plate to obtain the condensate.
