2122136 9308251 PCTABS00021 Surface-active agents-containing washing and/or cleaning agents, in particular textile washing agents, contain finely ground builder components, insoluble in use conditions, together with a minor amount of at least partially soluble co-builders, preferably together with bleaching agents, as well as other usual components of washing and cleaning agents. The agents are characterized in that they contain as co-builders the oxidation products of polyglucosanes composed in statistical average of at least 15 % by moles oxidated anhydroglucose units having formula (I) and having a mean molecular weight below 15.000 approximately, and/or their soluble salts, preferably the corresponding alkaline salts. Said co-builders are used to reduce incrustations resulting from washing textiles with phosphate-free textile washing agents based on finely ground, insoluble, in particular mineral builder components preferably zeolithe-NaA.
