The use is disclosed of a compound having the general formula (I), as well as its alkali salts, as scaling inhibitors and/or (co)-builders. In the formula (I), R" stands for hydrogen and R and R' independently represent branched or non-branched aliphatic C4-28 radicals which can contain one or several double C-C and/or triple C-C bonds. Radicals R and R' may be interrupted by one or more non-adjacent oxygen atoms, NH groups and/or N-C1-4-alkyl groups, and may be substituted by one or more hydroxyl groups, primary amino groups and/or secondary C1-4-alkylamino groups; or radicals R and R" are hydrogen atoms and radical R' has the above-mentioned meaning; or R" has the meaning given above for R' and R and R' are hydrogen atoms.
