## Abstract

A method for use of substituted dihydroxyterephthalic acid amides in detergents and cleaning agents, for improving detergent or cleaning performance with respect to bleachable stains.

## Claims

### Claim 1

A method for treating stained textiles comprising the step of contacting the stained textile in a wash liquor with a compound of general formula (I),
in which m and n, independently of one another, represent 0 to 5 and A and B, independently of one another, represent —NR1R2, —N+R1R2R3X−, —SO3H or —SO3−Y+, and R1, R2 and R3, independently of one another, represent H or a straight-chain or branched-chain aliphatic hydrocarbon functional group having 1 to 3 carbon atoms, X− represents an anion and Y+ represents an alkali metal cation or an ammonium ion, in washing or cleaning agents.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the stained textile comprises a stain consisting of polymerizable substances selected from polyphenolic dyes.

### Claim 3 (depends on 2)

The method according to claim 2, characterized in that the stain is selected from stains caused by cherries, morello cherries, grapes, apples, pomegranates, chokeberries, plums, sea buckthorns, acai, kiwifruit, mango, grass, berries, coffee, tea, red cabbage, blood orange, eggplant, tomato, carrots, beetroot, spinach, paprika, red or blue potatoes, or red onions.

### Claim 4 (depends on 1)

The method according to claim 1, characterized in that, in the compounds of general formula (I), A and B are the same or are not oppositely charged.

### Claim 5 (depends on 1)

The method according to claim 1, characterized in that, in the compounds of general formula (I), X− is selected from the group consisting of lactate, citrate, tartrate, succinate, perchlorate, tetrafluoroborate, hexafluorophosphate, alkyl sulfonate, alkyl sulfate, hydrogen sulfate, sulfate, dihydrogen phosphate, hydrogen phosphate, phosphate, isocyanate, thiocyanate, nitrate, fluoride, chloride, bromide, hydrogen carbonate and carbonate and mixtures of at least two thereof.

### Claim 6 (depends on 1)

The method according to claim 1, characterized in that, in the compounds of general formula (I), m and n are, independently of one another, 1 or 2 and/or m and n are the same.

### Claim 7

A washing or cleaning agent, comprising from 0.001 wt. % to 20 wt. % of compounds of general formula (I),
in which m and n, independently of one another, represent 0 to 5 and A and B, independently of one another, represent —NR1R2, —N+R1R2R3X−, —SO3H or —SO3−Y+ and R1, R2 and R3, independently of one another, represent H or a straight-chain or branched-chain aliphatic hydrocarbon functional group having 1 to 3 carbon atoms, X− represents an anion and Y+ represents an alkali metal cation or an ammonium ion.

### Claim 8 (depends on 7)

The agent according to claim 7, characterized in that it does not contain a bleaching agent.

### Claim 9 (depends on 7)

The agent according to claim 7, containing from 0.01 wt. % to 10 wt. % of compounds of general formula (I).
