The invention relates to novel antimicrobial surfactants and their application in antimicrobial coating systems, in particular water borne coatings. Provided is a method for providing an antimicrobial surfactant, comprising the steps of: (a) providing a hyperbranched polyurea having blocked isocyanates at the end of the polymer branches by the polycondensation of AB.sub.2 monomers; (b) introducing tertiary amine groups by reacting said blocked isocyanates of the hyperbranched polyurea with a tertiary amine compound that is functionalized with OH, NH.sub.2, SH, or COO; and (c) quaternization of said tertiary amine groups by reacting with an alkylating agent to obtain a quaternized hyperbranched polymer having antimicrobial surfactant properties.

The present invention relates to a composition comprising an aqueous solution of a) a hydrophobically modified alkylene oxide polymer comprising a hydrophobic portion functionalized with a protonated secondary or tertiary amine or a quaternary ammonium salt and b) an acid and a salt thereof, which acid is phosphoric acid, nitrilotris(methylene)triphosphonic acid, hydrochloric acid, or sulfuric acid.
