Abstract:
A bleaching composition comprising:a) from 0.05 microM to 50 mM of a complex comprising an organic substance which forms the complex with a transition metal, the complex having the general formula (A1): [MaLkXn]Ymâ€ƒâ€ƒ(A1) â€ƒin which: M represents a metal selected from Mn(II)-(III)-(IV)-(V), Cu(I)-(II)-(III), Fe(I)-(II)-(III)-(IV), Co(I)-(II)-(III), Ni(I)-(II)-(III), Cr(II)-(III)-(IV)-(V)-(VI)-(VII), Ti(II)-(III)-(IV), V(II)-(III)-(IV)-(V), Mo(II)-(III)-(IV)-(V)-(VI), W(IV)-(V)-(VI), Pd(II), Ru(II)-(III)-(IV)-(V) and Ag(I)-(II); L represents a ligand, or its protonated or deprotonated analogue; X represents a coordinating species selected from any mono, bi or tri charged anions and any neutral molecules able to coordinate the metal in a mono, bi or tridentate manner; Y represents any non-coordinated counter ion; a represents an integer from 1 to 10; k represents an integer from 1 to 10; n represents zero or an integer from 1 to 10; and m represents zero or an integer from 1 to 20, said complex having a log P of less than 3; b) a source of active oxygen corresponding to 0.05 to 100 mM (w/v) of active oxygen; and c) a dry cleaning effective amount of liquid carbon dioxide.
