| 摘要 |
<p>The invention concerns an aqueous composition and a method for biocide treatment of surfaces, said composition comprising: (a) water, (b) a cationic surfactant having biocide effect and/or a cationic polymer having biocide effect, (c) a film-forming polymer forming a transparent film, (d) at least a water soluble block copolymer comprising at least an non-ionic hydrophilic block and at least a non-ionic hydrophilic block, and (e) optionally, a non-ionic surfactant. The composition is useful as biocide composition with persistent effect for treating surfaces, the biocide effect on the surface to be treated being preserved after rinsing several times.</p> |
