Abstract
A non-toxic cleaning agent with biocidal and dirt-removing properties, which is used together with a solvent, contains at least one surface-active agent and phosphorus-containing bioactive glass particles. The glass particles preferably release at least 300 &mgr;g of alkali metal ions per gram, have an average size of less than 400 &mgr;m and contain SiO , CaO, Na O, CaF , B O , K O and/or MgO, as well as P O . These cleaning agents are particularly well suited for cleaning surfaces and textile materials, for use in dishwashing detergents and particularly in medical and food-serving establishments.
