Claims9
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.
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.
