Abstract

L'invention concerne un procédé de stérilisation utilisant un stérilisateur liquide comprenant du peroxyde d'hydrogène, ledit stérilisateur liquide étant préparé par dissolution de peroxyde d'hydrogène dans un solvant, dans lequel un liquide ayant un point d'ébullition inférieur à 100°C est utilisé comme solvant. Par stérilisation d'un contenant en matière plastique moulé exemplifié par une bouteille de poly(téréphtalate d'éthylène) ou un contenant en papier par fixation d'un brouillard du stérilisateur liquide précité comprenant du peroxyde d'hydrogène sur celui-ci, un effet de stérilisation et un rendement de stérilisation peuvent être accrus et la quantité de stérilisateur restant dans le contenant peut être réduite.
