The latter comprises a salt optionally containing water of crystallization or urea or mixtures thereof with anhydrous sodium sulfate, wherein the salt containing water of crystallization should not undergo any phase transformation between 1 DEG C. and 45 DEG C. In addition, the mixture may contain up to 15% of detergent constituents, such as surfactant and sequestering agent. The average particle size of the individual component is from 0.1 to 0.6 mm, less than 1% by weight being larger than 1.6 mm in size.
