Process for the biocidal treatment of surfaces, by applying an aqueous biocidal composition containing a biocidal agent (B), a surfactant (SA) when the said biocide is hydrophobic, and at least one water-soluble or water-dispersible organic copolymer (C) comprising at least one oligomeric or macromolecular unit (D) which can interact with the said biocide or with the micelles of surfactant(s) containing the said biocide when it is hydrophobic, and at least one hydrophilic macromolecular unit (E) which can interact with the surface to be treated and optionally with the said biocide. Use of the copolymer (C) in a biocidal composition for the treatment of surfaces, as an agent for the vectorization and/or controlled release of the said biocide onto the surface to be treated.
