Abstract
The present invention relates to compounds which form, under perhydrolysis conditions, certain cationic organic peracids, to the use of said compounds for activating peroxygen compounds in the context of bleaching stains when washing textiles and cleaning hard surfaces, and to washing and cleaning agents that contain said compounds.
Claims20
A bleach-activating compound of general formula (I)
- in which
- A represents O, S or Se;
- Z represents an optionally substituted C1-30 alkylene, C3-30 cycloalkylene, arylene, alkylenearylene or arylenealkylene functional group;
- X− represents an anion;
- Y represents NR6, O, S or Se;
- R, R1, R2, R3, R4, R5 and R6 represent, independently of one another, H, a C1-30 alkyl, C3-30 cycloalkyl, aryl, alkylaryl or arylalkyl functional group;
- and
- n represents a number in the range of from 1 to 12,
- wherein, in the hydrocarbon functional groups, 1 or more non-adjacent carbon atoms not bonded to a heteroatom can be replaced by a heteroatom.
6 more elements
A method for washing laundry or for cleaning a hard surface, comprising the steps of:
- (a) providing an aqueous liquor including H202 or an inorganic peroxygen compound which yields H2O2 in water, and a compound according to general formula (I)
- in which
- A represents O, S or Se;
- Z represents an optionally substituted C1-30 alkylene, C3-30 cycloalkylene, arylene, alkylenearylene or arylenealkylene functional group;
- X− represents an anion;
- Y represents NR6, O, S or Se;
- R, R1, R2, R3, R4, R5 and R6 represent, independently of one another, H, a C1-30 alkyl, C3-30 cycloalkyl, aryl, alkylaryl or arylalkyl functional group;
- and
- n represents a number in the range of from 1 to 12;
- wherein, in the hydrocarbon functional groups, 1 or more non-adjacent carbon atoms not bonded to a heteroatom can be replaced by a heteroatom, and
- (b) bringing this liquor into contact with a textile to be washed or a hard surface to be cleaned.

- and
- n represents a number in the range of from 1 to 12;
- wherein, in the hydrocarbon functional groups, 1 or more non-adjacent carbon atoms not bonded to a heteroatom can be replaced by a heteroatom.
