  • Device and method for ultra-high temperature sterilization of an emulsion
    Patent number: 10328165
    Abstract: A method for high temperature sterilization of an emulsion, in particular a dermocosmetic preparation. The method includes the steps of gradually pre-heating, performing ultra-high temperature sterilization and gradually cooling the emulsion. The emulsion is heated up to a pre-heating temperature, which is the temperature of the emulsion at the stability limit. Ultra-high temperature sterilization is performed by infusion of the pre-heated emulsion by heating the emulsion up to a sterilization temperature, maintaining the emulsion at the sterilization temperature, and cooling the emulsion under a vacuum at an end-of-sterilization temperature. The emulsion is gradually cooled with agitation to a storage temperature.
    Type: Grant

    Date of Patent: June 25, 2019
    Assignee: PIERRE FABRE DERMO-COSMETIQUE
