DEVICE AND METHOD FOR STERILIZING AN EMULSION AT AN ULTRAHIGH TEMPERATURE PARTICULARLY A COSMETIC EMULSION FOR THE SKIN WHICH IS UNSTABLE AT THE STERILIZATION TEMPERATURE

摘要

The present invention relates to a method for the high temperature sterilization of emulsions, especially dermal cosmetic preparations, characterized in that it comprises the following steps: a. Progressively preheating (120) the emulsion to a maximum preheat temperature T1, which is the stability limit of the emulsion; b. Performing ultraheated sterilization (130) by injection of the emulsion thus preheated, wherein the step comprises the following steps: i. Rapid heating to a maximum sterilization temperature T2 (131); ii. (132) from the sterilization temperature to the ballast; iii. Flash cooling (133) under vacuum at a termination temperature T3 of sterilization; c. And gradually cooling (150) with stirring to the storage temperature T4.
