A liquid bleaching comprising: ```a first compartment containing a first aqueous composition comprising a source of active oxygen, such as hydrogen peroxide ```a second compartment containing a second aqueous composition having a pH of 2 to 6 and comprising a compound having the structural Formula I, such as methyl morpholinium acetonitrile methyl sulphate <EMI ID=1.1 HE=19 WI=50 LX=637 LY=1175 TI=CF> <PC>wherein A is a saturated ring formed of four carbon atoms and a heteroatom in addition to the N1 atom, <DL TSIZE=10> <DT>R1<DD>is selected from the group consisting of alkyl, aryl, alkoxy, alcohol and acetonitrile, <DT>R2 and R3<DD>are each selected from the group consisting of hydrogen, alkyl, aryl, alkoxy and alcohol, <DT>Y<DD>is an anionic counterion, and <DT>Z<DD>is in the range of 0 to 10. Also disclosed is a process for treating a surface using the liquid bleach. </DL> |
