摘要： Propellant mixtures and medicament aerosols which contain them are described for micronizing medicaments for pulmonary use. The propellant mixture is in a subcritical state and contains at least one component from a first class of propellant gasses and at least one component from a second class of propellant gasses. The first class includes propellant gasses with an evaporation enthalpy of 200 kJ/kg or less at 25° C. and a vapor pressure of 20 bars or more at 25° C., and the second class includes propellant gasses with an evaporation enthalpy of 300 kJ/kg or more at 25° C. and a vapor pressure of 10 bars or less at 25° C. By using this propellant mixture in a medicament aerosol, micronized medicaments are obtained in which approximately 80% by weight of the generated particles have less than 8 &mgr;m diameter.

摘要： The present invention relates to a method for the physical treatment of starch (derivatives) using densified gases, in which essentially the starting material is treated at process temperatures between 20 and 200° C. and at process pressures between 50 and 800° C. for at least one minute, the density of the densified gas (mixture) being >180 kg/m3. Suitable starting materials are, in particular, native plant starches, starch from genetically modified plants, or physically and/or chemically modified starches. The treatment with, in particular, densified carbon dioxide, can be carried out under defined pressure change sequences, for which, in particular, liquid aids, such as water or suitable organic solvents, can also be added. The starches thus treated have, in particular, advantages in the form of considerably reduced contents, or complete elimination, of accompanying substances, gelatinization enthalpy and gelatinization temperature, and also of the mean particle diameter and can thus be advantageously used in the food, pharmaceutical, chemistry and constructional chemistry and also agrochemical sectors, but also in other fields of application.
