Abstract
Compositions d'oxyde d'éthylène et de monochlorotétrafluoroéthane utiles en tant qu'agents de stérilisation. Ces nouvelles compositions sont acceptables pour l'environnement, possèdent des caractéristiques améliorées de suppression d'inflammabilité, et sont capables de maintenir une concentration d'oxyde d'éthylène supérieure à celle de compositions gazeuses de stérilisation classiques.
