ABSTRACT:
A bleaching composition is described that includes a peroxygen compound such as sodium perborate, an oxygen transfer agent in the form of a quaternary imine salt and a bleach precursor. The quaternary imine salt at relatively low concentrations enhances the activity of the precursor. A method for bleaching substrates is also provided, especially a method for cleaning fabrics.
