Verwendung von Polycarbonsäurehalbamiden als Zusatz zu Wasch- und Reinigungsmitteln

摘要

The invention concerns the use of polycarboxylic acid half-amides obtained by reacting (a) polymers containing anhydride groups and having an average molecular mass Mw of between 200 and 100 000, and (b) aminocarboxylic acids comprising a primary or secondary amino group, taurine, C1-C18 alkyltaurines and/or aminophosphonic acid, as an encrustation-inhibiting additive to phosphate-free and phosphate-reduced washing and cleaning agents.
