  • Device and process for the cryogenic filling of aerosol product batches
    Publication number: 20040011061
    Abstract: In order to avoid evaporation of the propellant gas during the pressure-free filling of an aerosol formulation provided with a readily volatile propellant gas, the product to be filled is cooled prior to being fed into a metering means. In this context, fluoro-chlorinated hydrocarbons such as, for instance, R11 have been used up until now as the coolant, but their use is no longer permitted in Germany and in other nations.
