Abstract
Official abstract text for this publication.
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 1 to 25% by weight of at least one salt of a sulfonic acid or of an organic acid, percentages referring to the total respective aqueous solution.
First claim
Opening claim text (preview).
1 . An aqueous solution, comprising (A) from 30 to 60% by weight of a complexing agent, which is selected from the group consisting of an alkali metal salt of methylglycine diacetic acid and an alkali metal salt of glutamic acid diacetic acid, and (B) from 1 to 25% by weight of at least one salt of a sulfonic acid and an organic acid, based on a total weight of the aqueous solution, wherein the aqueous solution is free from surfactants. 2 . The aqueous solution according to claim 1 , having a pH value of from 9 to 13. 3 . The aqueous solution according to claim 1 , wherein (B) is at least one alkali metal salt of acetic acid, tartaric acid, lactic acid, maleic acid, fumaric acid, and malic acid. 4 . The aqueous solution according to claim 1 , wherein (B) is at least one alkali metal salt of methyl sulfonic acid. 5 . The aqueous solution according to claim 1 , further comprising (C) a polyethylene glycol with an average molecular weight M n of from 400 to 10,000 g/mol. 6 . A process for making the aqueous solution according to claim 1 , the process comprising combining an aqueous solution of the complexing agent (A) with the salt (B). 7 . A process for manufacturing a laundry care of dish wash formulation, the process comprising: employing the aqueous solutions according to claim 1 in the process. 8 . A process for transportation in a pipe or a container, the process comprising: employing the aqueous solution according to claim 1 in the process.
