ABSTRACT:
A bleaching composition is described that includes a peroxygen compound such as sodium perborate, an oxygen transfer agent such as a sulfonimine, and a bleach precursor such as TAED. These sulfonimines at relatively low concentrations enhance the activity of the precursor. A method for bleaching substrates is also provided, especially a method for cleaning fabrics.
