Abstract
Die Oxidations- und Bleichwirkung anorganischer Persauerstoffverbindungen bei niedrigen Temperaturen, insbesondere bei der Reinigung harter Oberflächen, sollte verbessert werden. Dies gelang im wesentlichen durch den Einsatz von Wolframat und/oder Molybdat. Mittel zur insbesondere maschinellen Reinigung von Geschirr enthalten etwa 0,01 Gew.-% bis 5 Gew.-% eines derartigen bleichverstärkenden Wirkstoffs in Kombination mit Polycarboxylaten und/oder Enzymen.The oxidation and bleaching effect of inorganic peroxygen compounds low temperatures, especially when cleaning hard surfaces, should be improved. This was largely achieved through the use of tungstate and / or molybdate. Contain agents for in particular machine cleaning of dishes about 0.01% to 5% by weight of such a bleach-boosting active ingredient in Combination with polycarboxylates and / or enzymes.
