Abstract (en)

2.1. Besides the main builder zeolite A, low-phosphate and phosphate-free detergents and cleaning agents require so-called co-builders, which increase the effectiveness of the detergents. Use of a novel co-builder is intended to decrease the secondary washing effects such as greying and encrustation. 2.2. In addition to the customary components such as surfactant, calcium-binding silicate, etc., the novel detergent contains at least 1% by weight of a polycarboxylate having the schematic structure (X, Y, Z), in which X is <IMAGE> Y is <IMAGE> and Z is -(F)q-. These carboxylates can be prepared from acrolein and, if desired, one or more comonomers by means of oxidising free radical donors without hydrolysing conditions and/or without subsequent Cannizzaro reaction. The novel co-builders show improvements in all basic detergent properties compared with co-builders conventionally used. 2.3. Detergent, detergent for delicate articles, colour detergent, liquid detergent, compact detergent.

Abstract (de)

Das neue Waschmittel enthält neben den üblichen Komponenten wie Tensid, calciumbindendes Silikat, etc. mindestens 1 Gew.-% eines Polycarboxylats mit der schematischen Struktur (X,Y,Z), worin X für <IMAGE> Y für <IMAGE> und Z für -(F)q- steht. Diese Carboxylate lassen sich aus Acrolein und ggf. einem oder mehreren Comonomeren mittels oxidierender Radikalspender ohne verseifende Bedingungen und/oder ohne anschließender Cannizzaro-Reaktion herstellen.
