Definitions

• Detergents and cleaning agents for aqueous applications are generally composed of a combination of various surface-active substances and other auxiliaries.
• softeners should be mentioned primarily, i.e. Substances that are able to bind the hardness constituents of water, especially Ca++ and Mg++ cations.
• Nitrilotriacetic acid and its salts have recently been used as a replacement for the phosphates, but these compounds are also not fully satisfactory since they deposit deposits of hardness, e.g. on textile fabrics, not preventing them effectively enough.
• the present invention was therefore based on detergents and cleaning agents for aqueous applications, which contain softeners which are even more effective than nitrilotriacetic acid.
• detergents and cleaning agents for aqueous applications which contain 2 to 25% by weight, based on the total weight of the detergents, of ⁇ -alanine-N, N-diacetic acid or its alkali metal or ammonium salts.
• ß-Alanine-N, N-diacetic acid like nitrilotriacetic acid, is biodegradable and can be produced particularly advantageously by reacting acrylic acid with iminodiacetic acid in an aqueous medium in large quantities (see our more recent application P 38 29 859.7 - OZ 0050/40154).
• ß-alanine-N, N-diacetic acid is its lower binding capacity for heavy metal ions such as Cu2+ or Cd2+ compared to nitrilotriacetic acid, such as a comparison of the corresponding equilibrium constants on pages 564 and 565 in Organic Sequestering Agents, A.E. Martell, J. Wiley & Sons, Hew York (1959). This reduces the likelihood that traces of undegraded ß-alanine-N, N-diacetic acid in river sediments will release heavy metal ions.
• the ⁇ -alanine-N, N-diacetic acid or its alkali metal or ammonium salts are used in amounts of 2 to 25, preferably in amounts of 5 to 15,% by weight.
• Their alkali metal salts are used with particular advantage, the trisodium salt being particularly preferred.
• the salts of ⁇ -alanine-N, N-diacetic acid with basic compounds such as potassium hydroxide, ammonia or primary, secondary or tertiary aliphatic organic amines having 1 to 4 carbon atoms in the aliphatic radicals such as methylamine, dimethylamine or trimethylamine can also be used .
• Detergents generally also contain 5 to 50% by weight of other softeners 6 to 25% by weight of surface-active compounds as washing-active substances 5 to 35 wt% bleach 0 to 60% by weight of substances essential for the consistency of the preparation and in minor amounts other auxiliary substances such as bleach stabilizers, bleach activators, enzymes, graying inhibitors, foam regulators, corrosion inhibitors, optical brighteners, solubilizers, fragrances or dyes.
• Cleaning agents generally contain other essential ingredients 30 to 80 wt .-% dirt-disrupting components 3 to 20% by weight of other agents which are able to bind hardening agents 2 to 10% by weight of surface-active substances 1 to 5% by weight of anti-corrosion agent 0 to 60% by weight of substances essential for the consistency of the preparation and in minor quantities other auxiliary substances such as enzymes, foam regulators, fragrances, solubilizers or disinfectants.
• the washing and cleaning agents according to the invention can contain alkaline substances such as sodium carbonate, sodium silicate and sodium phosphate or complexing agents of an inorganic nature such as e.g.

• Zeolite 4A whose production is described in Ullmann's Encyclopedia of Industrial Chemistry, 4th Edition, Volume 24 on p. 120, is particularly suitable as an ion exchanger.
