Suitable bleach activators for use herein include those belonging to the class of esters, amides, imides or anhydrides. Examples of suitable compounds of this type are disclosed in the British patents GB 1 586 769 and GB 2 143 231 discloses a process for their formation in prilled form is described in published European Patent Application EP-A-62 523. Suitable examples of such compounds for use herein are tetraacetylethylenediamine (TAED), sodium 3,5,5-trimethylhexanoyloxybenzenesulfonate, diperoxydodecanoic acid, as described, for example, in U.S. Patent 4,818,425, and the nonylamide of peroxyadipic acid, as disclosed, for example, in U.S. Patent 4 259 201, and n-nonanoyloxybenzenesulfonate (NOBS). Also suitable are N-acyl caprolactams selected from the group consisting of substituted or unsubstituted benzoyl caprolactam, octanoyl caprolactam, nonanoyl caprolactam, hexanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, formyl caprolactam, acetyl caprolactam, propanoyl caprolactam, butanoyl caprolactam, pentanoyl caprolactam or mixtures thereof. A particularly interesting family of bleach activators has been found in EP 624 154 disclosed, and particularly preferred in this family is acetyl triethyl citrate (ATC). Acetyl triethyl citrate has the advantage that it is environmentally friendly as it eventually degrades to citric acid and alcohol. In addition, acetyl triethyl citrate has a good hydrolytic stability in the product upon storage and is an effective bleach activator. Finally, it gives the composition a good builder capacity.
