Title (EN) NANOSILICA-BASED FOOD CONTACT SANITIZER
(FR) DESINFECTANT POUR CONTACT ALIMENTAIRE A BASE DE NANOSILICE
Abstract: front page image
(EN)Described herein are nanoparticle silica Pickering emulsions comprising an aqueous suspension of colloidal silica mixed with a quaternary ammonium biocide. Additionally, the composition may include a small amount of organic solvent; such as methanol, ethanol, isopropanol, and mixtures thereof; wetting agents, such as a silicone-based wetting agent; and organic bases which act as solvent buffers, if it is desirable to raise the pH of the composition, such as monoethanolamine (MEA). The combination of nanoparticle silica and quaternary ammonium biocide provides food contact sanitization at less than 200 ppm of quaternary ammonium active.
(FR)L'invention concerne des émulsions de Pickering à base de nanoparticules de silice comprenant une suspension aqueuse de solice colloïdale mélangée à un biocide d'ammonium quaternaire. La composition peut, de plus, comprendre une petite quantité de solvant organique, tel que le méthanol, l'éthanol, l'isopropanol, et des mélanges de ceux-ci; des agent mouillants, tels qu'un agent mouillant à base de silicone; et des bases organiques agissant comme tampons de solvant, s'il est désirable d'élever le pH de la composition, par exemple la monoéthanolamine (MEA). La combinaison des nanoparticules de silice et du biocide d'ammonium quaternaire permet la désinfection pour contact alimentaire à moins de 200 ppm d'ammonium quaternaire actif.
