Abstract

Die neuen Tensidzusammensetzungen werden durch Zusammenmischen von 1 Gew.-Teil von mindestens einem nichtionischen Tensid und 0,3 bis 9 Gew.-Teilen von einer speziellen Mischung aus Wasser und mindestens einem Anion-Tensid und mindestens einem Kation-Tensid erhälten. Sie stellen konzentrierte und im allgemeinen klare Flüssigkeiten dar, die sich insbesondere durch ein günstiges Schaum- und Netzverhalten, geringe Oberflächenspannung und niedrigen Stockpunkt auszeichnen und aufgrund dieser besonderen Eigenschaften vielfach verwendet werden können.
