Abstract

En fremgangsmåte for belegging av dråper eller nanometriske partikler omfattende: (1) fremstilling av en fin dispersjon av dråper eller partikler som inneholder, eller dannet av, et kjemisk eller biologisk aktivt mater- iale i en fase som utgjøres av et opp- løsningsmiddel og et ikke-oppløsnings- middel for polymeren som danner be- legget, og eventuelt et overflateaktivt middel eller suspensjonsmiddel; (2) fremstilling av en fase som inneholder den beleggdannende polymer oppløst i et ! blandbart oppløsningsmiddel i ethvert i forhold med den første dispersjon, (3) ! blanding av begge fasene kontinuerlig ; under opprettholdelse av et konstant forhold mellom fasene og blandings- volumet, og samtidig spraying av den ; dannede blanding i et fordampingssystem med temperatur og vakuumbetingelser som tilveiebringer umiddelbar fordamping av ¿ oppløsningsmiddel fra polymeren, hvilket forårsaker avsetning av poly- meren av partiklene eller dråpene. Produktet kan anvendes i farmasøytiske, medisinske, kosmetiske, veterinær- medisinske, industrik J etniske og jord- / brukspreparater.
