IMPROVEMENTS IN OR RELATING TO CLEANING COMPOSITIONS |
摘要 |
An aqueous cleaning composition comprises dye, preferably an acid dye, which is substantive to protein; water-miscible solvent; and surfactant, preferably alkoxylated surfactant. The dye can bind to protein to form a visible coloured complex and so reveal soil, with the surfactant (and also to some extent the solvent) performing a cleaning function to remove soil. By visualising protein, soil can be targetted for cleaning. Any dye remaining visible after cleaning indicates imperfect cleaning. |
