Abstract

En endring i overflateegenskapene til et apparat for farmasøytiske preparater følger av dampsterilisering. Denne endringen kan unngås ved å benytte et apparat med mer hydrofile overflater etter sterilisering, f.eks. av gull.Følgelig beskrives en prosess for fremstilling av en blanding omfattende en dispers fase i en kontinuerlig fase som omfatter å benytte et blandeapparat med ikke-porøs blandeflate som virker avstøtende på den disperse fasen og/eller tiltrekkende på den kontinuerlige fasen når den kontinuerlige fasen er flytende, eller virker tiltrekkende på den disperse fasen når den kontinuerlige fasen er i gassform, for på denne måte å forbedre effektiviteten ved fremstillingen av den nevnte blandingen og/eller redusere den fysiske nedbrytingen av den nevnte blandeflaten, der den nevnte flaten hvis den er hydrofil blir mer hydrofil etter sterilisering enn rustfritt stål er, og hvis den er hydrofob blir mer hydrofob etter sterilisering enn rustfritt stål er.A change in the surface properties of an apparatus for pharmaceutical preparations follows from steam sterilization. This change can be avoided by using an apparatus with more hydrophilic surfaces after sterilization, e.g. Accordingly, a process for preparing a composition comprising a dispersed phase in a continuous phase is described which comprises using a mixer with a non-porous mixing surface which acts repulsively on the disperse phase and / or attracts on the continuous phase when the continuous phase is liquid, or has an attractive effect on the disperse phase when the continuous phase is in gaseous form, in order in this way to improve the efficiency in the preparation of said mixture and / or to reduce the physical degradation of said mixing surface, where said surface if it is hydrophilic becomes more hydrophilic after sterilization than stainless steel is, and if it is hydrophobic becomes more hydrophobic after sterilization than stainless steel is.
