    Abstract: A method for the preparation of a crystalline solid comprising a glycine-N,N-diacetic acid derivative of formula (I) with a very low hygroscopicity, comprises fixing the water content of the starting material containing (I) at 10-30 wt.% and then carrying out crystallisation: MOOC-CH(R)-N(CH2COOM)2 (I) R = 1-30C alkyl or 2-30C alkenyl (both optionally containing 1-5 OH, formyl, 1-4C alkoxy(carbonyl) or phenoxy groups and/or optionally containing up to 5 non-adjacent O atoms in the chain), alkoxylate groups of formula (II), phenyl-(1-20 C)-alkyl (optionally containing up to 3 1-4C alkyl, OH, carboxyl, sulpho or 1-4C alkoxycarbonyl ring substituents), 5- or 6-membered optionally benzalated heterocyclic ring containing up to 3 N, O or S atoms (optionally containing up to 3 1-4C alkyl, OH, carboxyl, sulpho or 1-4C alkoxycarbonyl substituents) or a group of formula (III): -(CH2)k-O-(A O)m-(A O)n-Y (II) -A-CH(COOM)-N(CH2COOM)2 (III) A , A = 2-4C 1,2-alkylene; Y = H, 1-12C alkyl, phenyl or 1-4C alkoxycarbonyl; k = 1-3; m, n = 0-50; A = 1-12C alkylene or single bond; and M = H, alkali(ne earth) metal or optionally substituted ammonium, with the provision that m+n = at least 4.

    Abstract: The invention relates to a detergent and cleaning agent formulation, containing, besides other usual components, a bleaching system based on hydrogen peroxide, peroxo compounds and/or peracids, as well as a mixture of (A) largely biodegradable aliphatic or alicyclic amine with 1-12 C-atoms, which can, in addition, carry hydroxyl groups, and (B) complexing agents having a complexing effect on heavy metals, whereby the weight ratio of A:B ranges from 20:1, in particular from 1:5 to 5:1. The above mixture of amines (A) and complexing agents (B) has a stabilizing effect on the bleaching system.

    Abstract: Disclosed is an active substance composition, specially a cosmetic agent, a light-screening agent or a vitamin composition, containing one or several compounds of formula (I), specially an active substance composition, containing as a compound of formula (I) ethylene diaminosuccinate (EDDS), ethylene diaminoglutamate (EDDG) or (2-hydroxy propylene)-1,3-diaminosuccinate (HPDDS). The invention also relates to the use of bis(dicarboxylic acid) diaminoalkylene derivatives of the above formula (I) as complexing agents for earth alkaline metal ions and heavy metal ions in active substance compositions, specially cosmetic agents, screening agents, vitamin compositions and for stabilizing oxidation-sensitive active substances.

    Abstract: A process is disclosed for preparing aspartic acid polycondensates with improved biological degradability by thermal polycondensation of finely powdered aspartic acid in solid phase, at temperatures from 180 to 250 DEG C, until maximum 70 % by weight of the theoretically possible amount of water produced during polycondensation are removed from the reaction mixture. Also disclosed is the use of the thus produced polycondensates as additives for washing and cleaning agents and as scale inhibitors.
