Abstract
An improved bleaching and cleaning composition comprising a percompound and an organic activator therefor having at least one RCON<group in the molecule wherein RCO represents a carboxylic acyl radical, of which the peracid generation and bleaching performance are enhanced by the incorporation therein of a compound selected from the group having the following general formula: ##STR1## wherein n=1-4; and X=H or an alkali metal or alkaline earth metal or ammonium cation; ##STR2## wherein n=0-2; X=H or an alkali metal or alkaline earth metal or ammonium cation Y=H, CH.sub.2 COOX or CH.sub.2 PO.sub.3 X.sub.2 Z=H, CH.sub.2 COOX or CH.sub.2 PO.sub.3 X.sub.2 (X=H or an alkali metal or alkaline earth metal or ammonium cation). ##STR3## wherein n=1-3; and X=H, an alkali metal, alkaline earth metal or ammonium cation.
Claims5
A bleaching and cleaning composition comprising a percompound which liberates active oxygen in solution, an organic activator therefor having at least one RCON<
- group in the molecule wherein RCO represents a carboxylic acyl radical, at a molar ratio of percompound to activator of from 0.5:1 to about 35:1, and a compound selected from the group of compounds having the general formulae:
- ##STR14## wherein n=1-4;
- and X is H or an alkali metal or alkaline earth metal or ammonium cation;
- ##STR15## wherein n=0-2;
- X is H or an alkali metal or alkaline earth metal or ammonium cation,
- Y=H, CH.sub.2 COOX or CH.sub.2 PO.sub.3 X.sub.2
- Z=H, CH.sub.2 COOX or CH.sub.2 PO.sub.3 X.sub.2
- (X is H or an alkali metal or alkaline earth metal or ammonium cation) ##STR16## wherein n=1-3;
- and X is H or an alkali metal or alkaline earth metal or ammonium cation, in a proportion of 0.05 to 5.0% by weight and optionally from 0-50% by weight of a surface-active detergent, selected from the group consisting of anionic, nonionic, ampholytic and zwitterionic detergents, and from 0-80% by weight of a detergency builder.
