Beschreibung
Zusammenfassung:	Aqueous solutions containing salts of amino-(methylene phosphonic acids) with at least 6 phosphonic acid groups, or mixtures of the corresponding free acids. Aqueous solutions containing salts of phosphonic acids of formula (I): n = 3, 4 and/or 5 with an active substance content (based on free phosphonic acid) of at least 25 wt. % , obtained by partial neutralization of at least one phosphonic acid group per molecule. An Independent claim is also included for aqueous solutions containing mixtures of free phosphonic acids of formula (I) or a similar formula (II) with the index n replaced by n'. n and n' = 1, 2, 3, 4 and/or 5 with an active substance content as above, comprising at least two acids of formula (II) with n not equal to n' and with an active substance content of at least 25 wt. % based on complex former content.
