Abstract: Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung eines lagerstabilen Granulates bestehend im wesentlichen aus einem Bleichaktivator und einem anorganischen Bindematerial, gekennzeichnet durch die Verfahrensschritte:
a) Vermischen eines trockenen Bleichaktivators mit einem trockenen anorganischen Bindematerial,
b) Verpressen dieser Mischung zu größeren Agglomeraten und
c) Zerkleinern dieser Agglomerate auf die gewünschte Korngröße.
Weiterer Gegenstand der Erfindung ist die Verwendung, der nach diesen Verfahren hergestellten Granulate in Wasch-, Reinigungs-, Blech- und Desinfektionsmitteln.-

Abstract: The present invention relates to a process for the preparation of storage-stable granules essentially comprising a bleaching activator and an inorganic binder material, which comprises the process steps: a) mixing of a dry bleaching activator with a dry inorganic binder material, b) pressing of this mixture to give relatively large agglomerates and c) comminution of these agglomerates to the desired particle size. The invention furthermore relates to the use of the granules prepared by the processes in detergents, cleaning compositions, bleaching compositions and disinfectants.

Abstract: Esters of carboxylic acids, in particular esters of fatty acids, are reacted with ethylene oxide, propylene oxide and/or butylene oxide in the presence of an alkali metal or alkaline earth metal compound from the group comprising the hydroxides, oxides and alkoxides as catalyst at a temperature of 100 to 200 DEG C with direct incorporation of the alkylene oxide in the carboxylic acid ester. The carboxylic acid alkylene glycol ether esters are obtained in high yield and in good quality. They are in particular suitable as an active component in detergents.
