Description

ABSTRACT:
A solid detergent bleach composition adapted for use at substantially any washing temperature, comprising essentially a detergent active compound and a synergistic mixture of a solid organic peroxy acid compound e.g. diperoxyazelaic acid, an inorganic peroxy compound e.g. sodium perborate and a stabilizing sequestering agent. The composition which is preferably presented in the form of a particulate product, shows improved bleaching effect at substantially all washing temperatures. It has also advantages over compositions comprising bleaching activators in that it does not suffer from problems of in situ peroxy acid generation.
