Abstract

In a washing or cleaning agent that contains a solid enzyme formulation, the intention is to improve shelf stability in terms of enzymatic activity. This is achieved by a washing or cleaning agent comprising an enzyme granulate, the granulate comprising, besides the enzyme, the following components: (a) 68 to 90 wt % (w/w) sulfate, in particular alkali metal sulfate, particularly preferably sodium sulfate, (b) 0.1 to 10.5 wt % (w/w) polyethylene glycol, (c) 0.5 to 14.5 wt % (w/w) granulation adjuvant.
