A builder-containing laundry detergent or cleaning composition comprising: (1) a water-soluble builder block which comprised of: a) from 5% by weight to 35% by weight of citric acid, an alkali metal citrate, an alkali metal carbonate, and/or an alkali metal hydrogen carbonate, b) up to 5% by weight of alkali metal silicate having a modulus in the range from 1.8 to 2.5, c) up to 2% by weight of phosphonic acid and/or alkali metal phosphate, d) up to 50% by weight of alkali metal phosphate, and e) up to 10% by weight of polymeric polycarboxylate, wherein at least two of components b), c), d) and e) are present in amounts greater than 0% by weight, and (2) a soil release-capable alkyl or hydroxyalkyl cellulose derivative. The soil release-capable action of cellulose derivatives is particularly marked when they are used in laundry detergents or cleaning compositions which comprise only water-soluble builders.
