Patent

CA 2682515

Disclosed is a sterilizing composition including (i) at least one mono or dialdehyde; (ii) at ieast one glycol or polyol or derivative thereof; (iii) a non-ionic first surfactant; and (iv) a second surfactant having a cloud point in the range of about 30~C to 50~C. Also disclosed is a sterilizing composition including (i) at least one mono or dialdehyde;(ii) at least one glycol or polyol or derivative thereof; (iii) a non-ionic first surfactant; and (iv) a second surfactant, wherein the second surfactant is a quaternary ammonium compound, A process for preparing the compositions of the invention is also disclosed. The compositions of the invention are low or substantially non-foaming under high pressure, high temperature conditions, thus allowing maximum benefit from the new, more reliable, generation of automated endoscope reprocessing machine

L'invention concerne une composition stérilisante qui inclut (i) au moins un mono ou dialdéhyde; (ii) au moins un glycol ou un polyol ou un dérivé de ces composés; (iii) un premier agent tensioactif non ionique; et (iv) un second agent tensioactif ayant un point de trouble dans la plage d'environ 30°C à 50°C. L'invention concerne également une composition stérilisante qui inclut (i) au moins un mono ou dialdéhyde; (ii) au moins un glycol ou un polyol ou un dérivé de ces composés; (iii) un premier agent tensioactif non ionique; et (iv) un second agent tensioactif, ledit second agent tensioactif étant un composé d'ammonium quaternaire. L'invention concerne en outre un procédé de préparation des compositions de l'invention. Les compositions de l'invention sont faiblement ou pratiquement pas moussantes dans des conditions de haute pression et de haute température, permettant de cette façon tirer le meilleur profit de la nouvelle génération plus fiable de machines automatisées de retraitement des endoscopes.
