Abstract
There is provided an enzymatic oxidation composition and process wherein an oxidisable substance is reacted with (a) a compound having the formula: 1 and (b) molecular oxygen, in the absence of peroxidase. The process is useful in detergent compositions for stain bleaching and/or anti dye-transfer.
Claims21
Oxidation process wherein an oxidisable substance is reacted with:
- (a) a compound having the formula:
- 10
- wherein Z1 is any organic group e.g. (substituted)-(hetero)-(polycyclic)-aromatic, substituted (cyclo)-alkyl containing hetero atoms, and Z2 is electron withdrawing group (as described in J. March, ′Advanced Organic Chemistry, pg 17, 3d ed. (1985)), selected from the group consisting of optionally substituted alkyl/(hetero)aryl- -sulfone, -sulfoxide, -sulfonate, -carbonyl, -oxalyl, -amidoxalyl, -hydrazidoxalyl, -carboxyl and esters salts thereof, -amidyl, -hydrazidyl, nitrile, and (b) molecular oxygen, in the absence of peroxidase.
A composition for oxidizing substances, comprising a compound having the formula:
- 15
- wherein Z1 is any organic group e.g. (substituted)-(hetero)-(polycyclic)-aromatic, substituted (cyclo)-alkyl containing hetero atoms, and Z2 is electron withdrawing group (as described in J. March, ′Advanced Organic Chemistry, pg 17, 3d ed. (1985)), selected from the group consisting of optionally substituted alkyl/(hetero)aryl- -sulfone, -sulfoxide, -sulfonate, -carbonyl, -oxalyl, -amidoxalyl, -hydrazidoxalyl, -carboxyl and esters salts thereof, -amidyl, -hydrazidyl, nitrile, said composition being essentially free from peroxidase.
A detergent composition for stain bleaching and/or anti dye-transfer, comprising:
- (a) a surfactant and (b) a compound having the formula:
- 20
- wherein Z1 is any organic group e.g. (substituted)-(hetero)-(polycyclic)-aromatic, substituted (cyclo)-alkyl containing hetero atoms, and Z2 is electron withdrawing group (as described in J. March, ′Advanced Organic Chemistry, pg 17, 3d ed. (1985)), selected from the group consisting of optionally substituted alkyl/(hetero)aryl- -sulfone, -sulfoxide, -sulfonate, -carbonyl, -oxalyl, -amidoxalyl, -hydrazidoxalyl, -carboxyl and esters salts thereof, -amidyl, -hydrazidyl, nitrile, said composition being essentially free from peroxidase.
