Abstract

Cleaning and washing compositions for aqueous uses which contain as hardness remover 2 to 25% by weight, based on the total weight of the compositions, of beta -alanine-N,N-diacetic acid or the alkali metal or ammonium salts thereof.

Description

Die vorliegende Erfindung betrifft Waschmittel sowie Reinigungsmittel für wäßrige Anwendungen enthaltend als Enthärter 2 bis 25 Gew.-%, bezogen auf das Gesamtgewicht der Mittel, ß-Alanin-N,N-diessigsäure oder deren Alkalimetall- oder Ammoniumsalze.The present invention relates to detergents and cleaning agents for aqueous applications containing 2 to 25% by weight, as a softener, based on the total weight of the agents, ß-alanine-N, N-diacetic acid or its alkali metal or ammonium salts.

Waschmitel sowie Reinigungsmittel für wäßrige Anwendungen sind im allgemeinen aus einer Kombination verschiedener grenzflächenaktiver Substanzen und weiteren Hilfsstoffen zusammengesetzt.Detergents and cleaning agents for aqueous applications are generally composed of a combination of various surface-active substances and other auxiliaries.

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.Among the other aids, softeners should be mentioned primarily, i.e. Substances that are able to bind the hardness constituents of water, especially Ca⁺⁺ and Mg⁺⁺ cations.

Als Enthärter verwendete man bisher hauptsächlich Phosphate, die jedoch aus Gründen der Umweltbelastung zunehmend unerwünscht sind.So far, mainly phosphates have been used as softeners, but they are increasingly undesirable due to environmental pollution.

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.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.

Der vorliegenden Erfindung lagen daher Waschmittel sowie Reinigungsmittel für wäßrige Anwendungen als Aufgabe zugrunde, welche Enthärter enthalten, die noch besser wirksam sind als Nitrilotriessigsäure.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.

Demgemäß wurden Waschmittel sowie Reinigungsmittel für wäßrige Anwendungen gefunden, die als Enthärter 2 bis 25 Gew.-%, bezogen auf das Gesamtgewicht der Mittel, ß-Alanin-N,N-diessigsäure oder deren Alkalimetall- oder Ammoniumsalze enthalten.Accordingly, detergents and cleaning agents for aqueous applications have been found which contain 2 to 25% by weight, based on the total weight of the detergents, of β-alanine-N, N-diacetic acid or its alkali metal or ammonium salts.

ß-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).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).

Ein zusätzlicher Vorteil der ß-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 ß-Alanin-N,N-diessigsäure in Flußsedimenten abgelagerte Schwermetallionen wieder freisetzen.An additional advantage of 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.

Bezogen auf das Gesamtgewicht der erfindungsgemäßen Wasch- und Reinigungs­mittel werden die ß-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. Jedoch können auch die Salze der ß-Alanin-N,N-diessigsäure mit basischen Verbindungen wie Kaliumhydroxid, Ammoniak oder primären, sekundären oder tertiären aliphatischen organischen Aminen mit 1 bis 4 C-Atomen in den aliphatischen Resten wie Methylamin, Dimethylamin oder Trimethylamin eingesetzt werden.Based on the total weight of the washing and cleaning agents according to the invention, the β-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. However, the salts of β-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 .

Die weiteren Bestandteile der erfindungsgemäßen Wasch- und Reinigungs­mittel richten sich nach dem speziellen Verwendungszweck.The other constituents of the washing and cleaning agents according to the invention depend on the specific use.
