Abstract
Aqueous composition and method for the biocidal treatment of surfaces, the said composition comprising: (a) water, (b) a cationic surfactant having a biocidal effect and/or a cationic polymer having a biocidal effect, (c) a film-forming polymer forming a transparent film, (d) at least one water-soluble block copolymer comprising at least one anionic hydrophilic block and at least one nonionic hydrophilic block, and, (e) optionally, a nonionic surfactant. Use of the composition as a biocidal composition with a persistent effect for the treatment of surfaces, the biocidal effect on the surface to be treated being retained after several rinses.
