<p>A detergent composition comprises fructan component (0.1-5 wt.%) and phosphonate (0.1-5 wt.%) in addition to surface-active agents, builders, conventional additives and optional components. A detergent composition comprises fructan component (0.1-5 wt.%) and phosphonate (0.1-5 wt.%). The fructan component is carboxyalkylinulin (with the alkyl moiety containing 1-4C), dicarboxyinulin having a degree of oxidation of 10-100% expressed as molar percentage of monosaccharide units converted into the corresponding analogs, 6-carboxyinulin, or fructan polycarboxylic acid having a degree of oxidative substitution of 0.2-2 and a degree of carboxyalkylation or carboxyacylation of 0.2-3. The phosphonate is (R 2) a-N-(R 1-PO 3H 2) n - a, phosphonobutane tricarboxylic acid, alkylene polyphosphonate (with the alkylene chain having 2-6C and the component containing at least two phosphonate groups), and/or alkylene polyamino polyphosphonate. The composition also contains surface-active agents, builders, conventional additives and optional components.</p> |
