Abstract
A bleaching/cleaning composition is provided that includes a surfactant, a peroxy bleach compound and a ligand L which is a macrocyclic organic compound of formula: ##STR1## wherein: t is an integer from 2 to 3; s is an integer from 3 to 4; R.sup.1, R.sup.2 and R.sup.3 are each independently hydrogen, alkyl, aryl or a substituted alkyl or aryl. The preferred ligand is 1,4,7-trimethyl-1,4,7-triazacyclononane.

A cleaning composition comprising from about 1 to 50% by weight of a surface active material and from 0.0015 to about 1.5% by weight of a ligand L, uncomplexed with manganese prior to addition to a wash medium, of formula (I):
- ##STR7## wherein:
- t is an integer from 2 to 3;
- s is an integer from 3 to 4;
- u is zero or one;
- R.sup.1, R.sup.2 and R.sup.3 are each optionally substituted and independently selected from the group consisting of hydrogen alkyl, and aryl.
A bleaching composition comprising from about 2 to 30% by weight of a peroxy compound and from 0.0015 to about 1.5% by weight of a ligand L, uncomplexed with manganese prior to addition to a wash medium, of formula (I):
- ##STR9## wherein:
- t is an integer from 2 or 3;
- s is an integer from 3 or 4;
- u is zero or one;
- R.sup.1, R.sup.2 and R.sup.3 are each optionally substituted and independently selected from the group consisting of hydrogen, alkyl, and aryl.
A detergent composition comprising
- i) from 2 to 30% by weight of a peroxy compound;
- ii) up to 50% by weight of a surface-active material;
