Claims4
A textile washing or cleaning agent comprising compounds of the general formula (I),
- in which R1, R2, R3, R4, and R5 mutually independently denote hydrogen or OH with the provision that at least three of said residues are OH, X denotes oxygen or NR, n is a number from 2 to 20, and Z denotes a cyclic or acyclic, straight-chain or branched-chain, n-bonded hydrocarbon residue having 2 to 100 carbon atoms, whose skeleton can be penetrated by one or more non-adjacent oxygen or nitrogen atoms and/or can be mono- or polysubstituted with hydrophilic groups such as NRR′, COOR, CONRR′, and/or OR, R and R′ mutually independently denote hydrogen or a cyclic or acyclic, straight-chain or branched-chain, aliphatic or aromatic hydrocarbon residue having 1 to 20 carbon atoms, and wherein the textile washing or cleaning agent further comprises a builder selected from the group of builders consisting of zeolites, silicates, carbonates, and organic cobuilders.
