Abstract:
Aqueous solution comprising (A) in the range of from 30 to 60% by weight of a complexing agent, selected from the alkali metal salts of methylglycine diacetic acid and the alkali metal salts of glutamic acid diacetic acid, (B) in the range of from 700 ppm to 7% by weight of a polymer being selected from polyamines, the N atoms being partially or fully substituted with CH2COOH groups, partially or fully neutralized with alkali metal cations, ppm and percentages referring to the total respective aqueous solution
Abstract:
Mixture of L- and D-enantiomers of methyl glycine diacetic acid (MGDA) or its respective mono-, di or trialkali metal or mono-, di- or triammonium salts, said mixture containing predominantly the respective L-isomer with an enantiomeric excess (ee) in the range of from 10 to 75 %.
Abstract:
The invention concerns formulations containing: (A) in total in the range of 1 to 50 wt.% of at least one compound selected from methylglycin diacetic acid (MGDA), glutamic acid diacetate (GLDA) and their salts; (B) in total in the range of 0.01 to 0.4 wt. % of at least one zinc salt, given as zinc; (C) in total in the range of 0.001 to 0.045 wt. % homo- or copolymer of ethylenimine; and (D) optionally 0.5 to 15 wt. % bleach, in each case relative to the solids content of the particular formulation.
