Definitions
- the present invention relates to detergents and cleaning agents for aqueous applications containing 2 to 25% by weight as softener, based on the total weight of the detergent, ⁇ -alanine-N, N-diacetic acid or its alkali metal or ammonium salts.
- 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 detergent, of ⁇ -alanine-N, N-diacetic acid or its alkali metal or ammonium salts as softener.
- Beta-alanine-N, N-diacetic 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 recent application P 38 29 859.7 - OZ 0050/40154).
- ⁇ -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 ⁇ -alanine-N, N-diacetic acid will release heavy metal ions deposited in river sediments.
- 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.

- 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.

Description
- Die vorliegende Erfindung betrifft Waschmittel sowie Reinigungsmittel für wäßrige Anwendungen enthaltend als Enthärter 2 bis 25 Gew.-%, bezogen auf das Gesamtgewicht der Mittel, β-Alanin-N,N-diessigsäure oder deren Alkalimetall- oder Ammoniumsalze.
- Waschmitel sowie Reinigungsmittel für wäßrige Anwendungen sind im allgemeinen aus einer Kombination verschiedener grenzflächenaktiver Substanzen und weiteren Hilfsstoffen zusammengesetzt.
- Unter den weiteren Hilfsmitteln sind in erster Linie Enthärter zu nennen, d.h. Substanzen, welche die Härtebildner des Wassers, vor allem Ca⁺⁺- und Mg⁺⁺-Kationen, zu binden vermögen.
- Als Enthärter verwendete man bisher hauptsächlich Phosphate, die jedoch aus Gründen der Umweltbelastung zunehmend unerwünscht sind.
- Als Ersatz für die Phosphate dienen in neuerer Zeit die Nitrilotriessigsäure und ihre Salze, jedoch vermögen auch diese Verbindungen nicht voll zu befriedigen, da sie Ablagerungen der Härtebildner, z.B. auf textilen Geweben, nicht wirksam genug verhindern.
- Der vorliegenden Erfindung lagen daher Waschmittel sowie Reinigungsmittel für wäßrige Anwendungen als Aufgabe zugrunde, welche Enthärter enthalten, die noch besser wirksam sind als Nitrilotriessigsäure.
- Demgemäß wurden Waschmittel sowie Reinigungsmittel für wäßrige Anwendungen gefunden, die als Enthärter 2 bis 25 Gew.-%, bezogen auf das Gesamtgewicht der Mittel, β-Alanin-N,N-diessigsäure oder deren Alkalimetall- oder Ammoniumsalze enthalten.
- β-Alanin-N,N-diessigsäure ist wie Nitrilotriessigsäure biologisch abbaubar und kann besonders vorteilhaft durch Umsetzung von Acrylsäure mit Iminodiessigsäure in wäßrigem Medium in großtechnischen Mengen hergestellt werden (siehe unsere jüngere Anmeldung P 38 29 859.7 - O.Z. 0050/40154).
- Ein zusätzlicher Vorteil der β-Alanin-N,N-diessigsäure ist ihr im Vergleich zur Nitrilotriessigsäure geringeres Bindevermögen für Schwermetallionen wie Cu²⁺ oder Cd²⁺, wie ein Vergleich der entsprechenden Gleichgewichtskonstanten auf den Seiten 564 und 565 in Organic Sequestering Agents, A.E. Martell, J. Wiley & Sons, Hew York (1959), ausweist. Dies verringert die Wahrscheinlichkeit, daß Spuren nicht abgebauter β-Alanin-N,N-diessigsäure in Flußsedimenten abgelagerte Schwermetallionen wieder freisetzen.
- Bezogen auf das Gesamtgewicht der erfindungsgemäßen Wasch- und Reinigungsmittel werden die β-Alanin-N,N-diessigsäure oder ihre Alkalimetall- oder Ammoniumsalze in Mengen von 2 bis 25, bevorzugt in Mengen von 5 bis 15 Gew.-% eingesetzt. Mit besonderem Vorteil werden ihre Alkalimetallsalze verwendet, wobei das Trinatriumsalz besonders bevorzugt wird.

Ein Maß für die beim Waschprozeß entstandenen Ablagerungen der Härtebildner ist der Gewichtsanteil an Asche, der beim Veraschen des gewaschenen Testgewebes zurückblieb.
