Phenolic derivatives have formulas (I) or (II), in which R1 stands for C¿6?-C20-alkyl or -alkenyl that may be interrupted by one or several non-adjacent oxygen atoms, or for a group having the formulas: -O-CO-R?5¿, -CO-O-R5-, -NH-CO-R?5, -NR6-CO-R5¿, -CO-NH-R5, -CO-NR6-R5, -NH-SO¿2?-R?5, -NR6-SO¿2-R5, -SO2-NH-R5 or -SO¿2?-NR?6-R5¿, in which R5 stands for C¿6?-C20-alkyl or alkenyl that may be interrupted by one or several non-adjacent oxygen atoms, and R?6¿ stands for C¿1?-C4-alkyl; R?2 and R3¿ stand for hydrogen or a group having the formula: -CH¿2?-N(CH2COOM)2, in which M stands for hydrogen, an alkaline metal, ammonium or substitued ammonium, whereas at least one of the residues R?2 or R3¿ must stand for a group having the formula: -CH¿2?-N(CH2)COOM)2; and R?4¿ stands for a group having the formulas: -CO-O-R5, -CO-NH-R5 or CO-NR6-R5. These phenolic derivatives having formulas (I) or (II) are used as alkaline earth and heavy metal ion complexing agents in (a) powdery textile washing compositions; (b) technical detergent compositions for hard surfaces made of metal, plastics, lacquer or glass; (c) alkaline detergent compositions for the beverage and food processing industry; (d) dish-washing compositions; (e) bleaching baths for the paper and cellulose industry; (f) photographic bleaching and bleach-hardening baths; (g) pre-processing, bleaching and dyeing baths in the textile industry; (h) galvanisation baths and (i) fertilisers. |
