Liquid laundry detergent compositions containing anionic or nonionic surfactant, citric acid or a water-soluble salt thereof, proteolytic enzyme, cellulase, and a mixture of 1,2 propane diol and boric acid or its derivative. The compositions are prepared by adding the diol and boric acid before adding the citric acid/salt to the composition. This order of addition improves the stability of the cellulase.
