Abstract:
A bleaching composition comprising an effective amount for bleaching free ligand capable of forming a complex with a transition metal, and at least 1% of a peroxyl species or equivalent source thereof,wherein the complex is of 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(II)-(III)-(IV)-(V), Co(I)-(II)-(III), Ti(II)-(III)-(IV), V(II)-(III)-(V), Mo(II)-(III)-(IV)-(V)-(VI) and W(IV)-(V)-(VT); 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 an integer from 1 to 10; m represents zero or an integer from 1 to 20; and L represents a ligand of the general formula (I), or its protonated or deprotonated analogue: â€ƒwherein R1, R2, and R3 independently represent a group selected from hydrogen, hydroxyl, halogen, â€”NHâ€”C(NH)NH2, â€”R and â€”OR, wherein R=alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl or a carbonyl derivative group, R being optionally substituted by one or more functional groups E; Q independently represents a group selected from C2-3-alkylene optionally substituted by H, benzyl or C1-8-alkyl; Q1, Q2 and Q3 independently represent a group of the formula: â€ƒwherein 5&gE;a+b+c&gE;1; a=0-5; b=0-5; c=0-5; n=1 or 2; Y independently represents a group selected from â€”Oâ€”, â€”Sâ€”, â€”SOâ€”, â€”SO2â€”, â€”C(O)â€”, arylene, alkylene, heteroarylene, heterocycloalkylene, â€”(G)Pâ€”, â€”P(O)â€” and â€”(G)Nâ€”, wherein G is selected from hydrogen, alkyl, aryl, arylalkyl, cycloalkyl, each except hydrogen being optionally substituted by one or more functional groups E; R5, R6, R7, R8 independently represent a group selected from hydrogen, hydroxyl, halogen, â€”R and â€”OR, wherein R represents alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl or a carbonyl derivative group, R being optionally substituted by one or more functional groups E, or R5 together with R6, or R7 together with R8, or both, represent oxygen, or R5 together with R7 and/or independently R6 together with R8, or R5 together with R8 and/or independently R6 together with R7, represent C1-6-alkylene optionally substituted by C1-4-alkyl, â€”F, â€”Cl, â€”Br or â€”I; and E independently represents a functional group selected from â€”F, â€”Cl, â€”Br, â€”I, â€”OH, â€”ORâ€², â€”NH2, â€”NHRâ€², â€”N(Râ€²)2, â€”N(Râ€²)3+, â€”C(O)Râ€², â€”OC(O)Râ€², â€”COOH, â€”COOâˆ’(Na+, K+), â€”COORâ€², â€”C(O)NH2, â€”C(O)NHRâ€², â€”C(O)N(Râ€²)2, heteroaryl, â€”Râ€², â€”SRâ€², â€”SH, â€”P(Râ€²)2, â€”P(O)(Râ€²)2, â€”P(O)(OH)2, â€”P(O)(ORâ€²)2, â€”NO2, â€”SO3H, â€”SO3âˆ’(Na+, K+), â€”S(O)2Râ€², â€”NHC(O)Râ€², and â€”N(Râ€²)C(O)Râ€², wherein Râ€² represents cycloalkyl, aryl, arylalkyl, or alkyl optionally substituted by â€”F, â€”Cl, â€”Br, â€”I, â€”NH3+, â€”SO3H, â€”SO3âˆ’(Na+, K+), â€”COOH, â€”COOâˆ’(Na+, K+), â€”P(O)(OH)2, or â€”P(O)(Oâˆ’(Na+, K+))2, provided that at Least one of R1, R2 and R3 is a coordinating group.
