Definitions
- the invention relates to a process for coating bleach activator-containing granules by treatment with an acidic aqueous strengthening solution which contains polymeric polycarboxylate and / or alkali metal phosphonate as the coating and strengthening active ingredient, with simultaneous drying in a fluidized bed apparatus.
- detergents and cleaning agents In addition to the ingredients that are indispensable for the washing process, such as surfactants and builder materials, detergents and cleaning agents generally contain other ingredients, which can be summarized under the term washing aids and which include such different active ingredient groups as foam regulators, graying inhibitors, bleaching agents and dye transfer inhibitors. Such auxiliaries also include substances that support the surfactant performance through the oxidative degradation of soiling on the textile or such in the fleet. The same applies analogously to cleaning agents for hard surfaces. Inorganic peroxygen compounds, in particular hydrogen peroxide and solid peroxygen compounds which dissolve in water with the liberation of hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes.
- oxidation effect of these substances in dilute solutions depends strongly on the temperature; For example, with H 2 O 2 or sodium perborate in alkaline bleaching liquors, sufficiently quick bleaching of soiled textiles can only be achieved at temperatures above about 60 ° C. At lower temperatures, the oxidation effect of the inorganic peroxygen compounds can be improved by the addition of so-called bleach activators, for which numerous suggestions, especially from the classes of the N- or O-acyl compounds, for example multiply acylated alkylenediamines, especially tetraacetylethylenediamine, acylated glycolurils, especially tetraacetylgly oluril , N-acylated hydantoins, hydrazides, triazoles, hydrotriazines, urazoles, diketopiperazines, sulfurylamides and cyanurates, and also carboxylic acid anhydrides, in particular phthalic anhydride, carboxylic acid esters, in particular Sodium non
