Washing agent compositions and washing assistant composition containing phosphonopolycarboxylate sequestering agents

摘要: Washing agent compositions and washing assistant containing from 0.5% to 70% by weight of a phosphonopolycarboxylate having the formula ##EQU1## WHEREIN Me is H, alkali metal, or H.NR3, R1 H CH3, R2 alkyl 1 4 carbon atoms --CH2 --CHR--COOMe, R3 alkylol 6 atoms, X direct bond groups ##EQU2## 0 96.5% other sequestering non-sequestering, preferably phosphorus-free builders, 3% 45% at least one surface-active compound an anionic non-ionic nature, whereby 1% aqueous solution thereof has pH between 11.5. Preferably said agents are present as water-soluble salts capable complex formation with alkaline earth metal ions. The invention also resides in process ions using solutions composition.
