Abstract
The present invention relates to liquid detergent compositions comprising: PA1 (1) 1-80% by wt. surfactant; PA1 (2) defined peroxyacid; and PA1 (3) 0.01-20% by wt. of N-oxide compound. The N-oxide compounds help to extend the half life of the peracid bleaches in such compositions. The invention further relates to a method of incorporating stability of surfactant compositions comprising peracid bleaches which method comprises adding 0.01-2.0% by wt. of said N-oxide compound to the composition.
