Abstract

L'invention concerne un désinfectant de surfaces biodégradable, hypocompatible et non toxique, efficace pour lutter contre une large gamme d'organismes pathogènes, pouvant absorber des matières organiques en les décollant des surfaces. Ce désinfectant est composé de constituants interactifs comprenant un tensioactif, un alcool monovalent proportionné en poids de telle façon que l'alcool polyvalent réduise l'enduit de la surface formé par l'alcool monovalent et la tension superficielle formée par l'eau ou les fluides biologiques à base d'eau, permettant au désinfectant de surfaces de tuer les organismes pathogènes sans qu'il y ait d'effets nocifs au niveau de la surface.
