Patent

CA 2688718

The present invention presents a biocidic packaging for cosmetics and/or foodstuffs, comprises at least one insoluble proton sink or source (PSS). The ackaging is provided useful for killing living target cells (LTCs), or otherwise disrupting vital intracellular processes and/or intercellular interactions of said LTC upon contact. The PSS comprises, inter alia, (i) proton source or sink providing a buffering capacity; and (ii) means providing proton conductivity and/or electrical potential. The PSS is effectively disrupting the pH homeostasis and/or electrical balance within the confined volume of the LTC and/or disrupting vital intercellular interactions of the LTCs while efficiently preserving the pH of said LTCs' environment. The present invention also discloses a method for killing living target cells (LTCs), or otherwise disrupting vital intracellular processes and/or intercellular interactions of said LTC being in a packaging, especially cosmetic or foodstuffs' packaging.

La présente invention concerne un emballage biocide destiné à des produits cosmétiques et/ou à des produits alimentaires, comprenant au moins un puits ou une source de protons non soluble (PSS). Cet emballage convient pour tuer des cellules cibles vivantes (LTC) ou pour dérégler des processus intracellulaires vitaux et/ou des interactions intercellulaires de LTC lors de la mise en contact. La PSS comprend, entre autres choses, (i) une source ou un puits de proton offrant une capacité de tampon, et (ii) un moyen fournissant une conductivité de protons et/ou un potentiel électrique. La PSS dérégle efficacement l'homéostase pH et/ou l'équilibre électrique à l'intérieur du volume confiné de la LTC et/ou dérégle des interactions intracellulaires vitales des LTC tout en préservant efficacement le pH de l'environnement des LTC. La présente invention concerne aussi un procédé permettant de tuer des cellules cible vivantes (LTC) ou de dérégler des processus intracellulaires vitaux et/ou des interactions intercellulaires de cette LTC, dans un emballage, en particulier un emballage de produits cosmétiques ou de produits alimentaires.
