    • Washing agent compositions and washing assistant compositions containing from 0.5% to 70% by weight of a phosphonopolycarboxylate having the formula ##EQU1## WHEREIN Me is H, alkali metal, or H.NR.sub.3, R.sub.1 is H or CH.sub.3, R.sub.2 is H, alkyl having 1 to 4 carbon atoms or --CH.sub.2 --CHR--COOMe, R.sub.3 is H, alkyl or alkylol having 1 to 6 carbon atoms, and X is a direct bond or the groups ##EQU2## from 0 to 96.5% of other sequestering and non-sequestering, preferably phosphorus-free builders, and from 3% to 45% by weight of at least one surface-active compound of an anionic or non-ionic nature, whereby a 1% aqueous solution thereof has a pH of between 6 and 11.5. Preferably said phosphonopolycarboxylate sequestering agents are present as water-soluble salts capable of complex formation with alkaline earth metal ions. The invention also resides in the process of sequestering alkaline earth metal ions using aqueous solutions of the washing agent composition.
    • 洗涤剂组合物和洗涤助剂组合物,其含有0.5重量%至70重量%的具有式COOMeCOOMe O || PARALLEL CH --- C-X-P-OMe || R1R2OMe的膦酸多羧酸酯,其中Me为H,碱 金属或H.NR 3,R 1为H或CH 3,R 2为H,具有1至4个碳原子的烷基或-CH 2 -CHR-COOMe,R 3为H,具有1至6个碳原子的烷基或烷醇,X为 直接键或基团COOMe COOMe OMe | | | -C-CH2-,-C-或O = P-OMe,| | | H R1 -C- | R1从0到96.5%的其他螯合和非螯合, 优选无磷助洗剂,和3重量%至45重量%的至少一种阴离子或非离子性表面活性化合物,其中1%的水溶液的pH为6至11.5。 优选地,所述膦酸多羧酸盐螯合剂作为能够与碱土金属离子复合形成的水溶性盐存在。 本发明还在于使用洗涤剂组合物的水溶液螯合碱土金属离子的过程。
