Abstract: The invention concerns the use of polymerizates containing, as the major monomer component, at least 5 % by wt. of N-(alkoxy-polyalkoxymethyl)carboxylic acid amides of monoethylenically unsaturated C3-C8 carboxylic acids as additives to low-phosphate and phosphate-free washing and cleaning agents in amounts which increase the primary and secondary washing capability of the agent, plus agents containing these polymerizates.
