PACKAGE WITH BIOCIDE PROPERTIES FOR COSMETICS AND FOOD PRODUCTS Russian patent published in 2012 - IPC B65B55/00 A01N61/00 

FIELD: transport, package.

SUBSTANCE: package with, at least, one charged polymer, in contact with water-bearing medium, wherein polymer includes high-alkali functional groups and features pH approximately under 4.5 or exceeding 8.0 and can generate surface electric potential inside cell closed space sufficient for efficient impairment of pH homeostasis and/or electric balance inside said closed space and exists in group including H⁺-form and OH^--form. Note here that said polymer can retain pH of cell ambient medium. Proposed method comprises providing, at least, one charged polymer, in contact with water-bearing medium, wherein polymer includes high-alkali functional groups and features pH approximately under 4.5 or exceeding 8.0 and can generate surface electric potential inside cell closed space sufficient for efficient impairment of pH homeostasis and/or electric balance inside said closed space. Said polymer exists in form selected from the group including group including H⁺-form and OH^--form and polymer adaptations to kind selected from the group: powder, gel, suspension, resin, coating, film, plate, pellet, particle, micro particle, nanoparticle, finer, thread, extruded element. Method of increasing death factor of live cells and/or decreasing the rate of their reproduction consists in providing, at least, one charged polymer, in contact with water-bearing medium, wherein polymer includes high-alkali functional groups and features pH approximately under 4.5 or exceeding 8.0 and can generate surface electric potential inside cell closed space sufficient for efficient impairment of pH homeostasis and/or electric balance inside said closed space sufficient for efficient impairment of pH homeostasis and/or electric balance inside said closed space and exists in group including H⁺-form and OH^--form. Method of package recovery consists in, at least one stage selected from the range of recovery of package ability to absorb and/or release protons, recover of package buffer capacity, and package proton conductivity recovery.

EFFECT: higher efficiency of killing cells inside package or impairing vital intercellular processes and/or intercellular interactions.
