    Abstract: The invention concerns condensation products containing N,O-acetal- or carbonamide structures, the products being characterized in that they are obtained by the condensation of (a) compounds containing at least once the structural element (I) or (II) in which X=OH or NHR, R being C1 to C6 alkyl or -CH2-COOH, with (b) aldehydes, ketones or aldehydic or ketonic carboxylic acids to give acetal lactones and by subsequently splitting the acetal lactones with (c) aminocarboxylic acids, primary or secondary amines and/or polyethylenimines to give condensation products containing N,O-acetal- or carbonamide structures. The invention also concerns methods of preparing such products and their use as additives in washing and cleaning agents. The invention further concerns condensation products containing acetal lactone structures produced by reacting (a) hydroxycarboxylic acids or secondary aminoacids with polyhydroxy compounds and condensing with (b) aldehydes, ketones or aldehydic or ketonic carboxylic acids.

    Abstract: Process for the production of polyesters from (a) citric acid or isocitric acid which may be replaced to the extent of up to 29 mol.% by mono or dibasic hydroxy carboxylic acids or by up to 60 mol.% of other di to tetrabasic aliphatic carboxylic acids, and (b) polyhydroxy compounds of the polysaccharide and modified polysaccharide or polyvinyl alcohol group or their mixtures in such a molar ratio (a):(b) that 1.25 to 12 mol of component (a) is used per quantity of component (b) containing 1 mol hydroxy groups, to form condensation products with a K of 8 to 120, and the use of the polyesters as additives in low-phosphate or phosphate-free washing and cleaning agents in quantities of 0.1 to 30 wt % related to the formulation employed.
