摘要:
A granular, storable bleach mixture suitable for addition to a detergent composition or to a wash liquor comprising a mixture of (a) from 5 to 35% by weight sodium perborate, preferably as monohydrate, (b) from 5 to 30% by weight tetra-acetyl ethylene-diamine and (c) from 90 to 50% by weight of a carrier material. 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.degree. C. and 45.degree. 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.
