Description
"Wasch-, Reinigungs- oder Spülmittel mit verbessertem Schaumverhalten" "Washing, cleaning or rinsing agents with improved foaming behavior"
Die Erfindung betrifft ein Wasch-, Reinigungs- oder Spülmittel, enthaltend Tensid(e) und ein The invention relates to a washing, cleaning or rinsing agent containing surfactant (s) and a
Hydroxycarbonsäuresalz. Die Erfindung betrifft auch Verfahren zur Herstellung des Wasch-, Reinigungsoder Spülmittels sowie dessen Verwendung. Hydroxycarboxylic. The invention also relates to processes for the preparation of the washing, cleaning or rinsing agent and its use.
In einigen Ländern, beispielsweise in vielen nordafrikanischen, arabischen oder asiatischen Ländern, wird die Wäsche meist noch mit der Hand oder mit einfachen Toploader-Waschmaschinen mit kurzen Waschzeiten (rund 12 Minuten) gewaschen. Bei der Handwäsche oder bei Einsatz der einfachen Toploader-Waschmaschinen ist eine starke und lang anhaltende Schaumbildung erwünscht, denn die Reinigungsleistung eines Wasch-, Reinigungs- oder Spülmittels wird von vielen Anwendern anhand des sichtbaren Schaums beurteilt. In some countries, for example in many North African, Arab or Asian countries, the laundry is usually washed by hand or by simple toploader washing machines with short washing times (around 12 minutes). When hand washing or using the simple Toploader washing machines a strong and long-lasting foaming is desired, because the cleaning performance of a washing, cleaning or rinsing agent is judged by many users on the basis of the visible foam.
Dasselbe gilt für Handgeschirrspülmittel. Auch dort bewirkt eine starke Schaumbildung eine Erhöhung der wahrgenommen Reinigungsleistung und somit eine höhere Zufriedenheit bei den Anwendern. The same applies to hand dishwashing detergents. There, too, a strong foaming causes an increase in the perceived cleaning performance and thus a higher satisfaction among the users.
Um eine ausreichende Schaumbildung und Schaumstabilität zu erzielen, werden Wasch-, Reinigungsoder Spülmitteln Schaum-fördernde Verbindungen, so genannte„Schaum-Booster", zugesetzt. Aus der EP 1739161 A1 ist beispielsweise die Verwendung von Alkylethercarboxylaten als Schaum-fördernde Verbindungen bekannt. Diese werden üblicherweise durch Alkoxylierung und anschließender Foaming compounds, so-called "foam boosters", are added to washing, cleaning or rinsing agents in order to achieve adequate foaming and foam stability. EP 1739161 A1 discloses, for example, the use of alkyl ether carboxylates as foam-promoting compounds usually by alkoxylation and subsequent
Carboxymethylierung aus Fettalkoholen erhalten. Carboxymethylation obtained from fatty alcohols.
Insbesondere im Hinblick auf das Thema„Nachhaltigkeit" ist es wünschenswert, das Schaumverhalten von Wasch-, Reinigungs- oder Spülmittel unter Einsatz von chemisch leicht zugänglichen und möglichst auf nachwachsenden Rohstoffen basierenden Verbindung zu verbessern. In particular with regard to the topic of "sustainability", it is desirable to improve the foaming behavior of detergents, cleaners or dishwashing detergents using chemically readily accessible and as far as possible based on renewable raw materials.
Entsprechend war es eine Aufgabe der Erfindung, ein Wasch-, Reinigungs- oder Spülmittel mit verbessertem Schaumverhalten bereit zu stellen, welches eine einfach zugängliche Schaum-fördernde Verbindung enthält. Accordingly, it was an object of the invention to provide a washing, cleaning or rinsing agent with improved foaming behavior, which contains an easily accessible foam-promoting compound.
Diese Aufgabe wird gelöst durch ein Wasch-, Reinigungs- oder Spülmittel, enthaltend This object is achieved by a washing, cleaning or rinsing agent containing
(a) 1 bis 70 Gew.-%, bezogen auf das gesamte Wasch-, Reinigungs- oder Spülmittel, Tensid(e) und (A) 1 to 70 wt .-%, based on the total washing, cleaning or rinsing agent, surfactant (s) and
(b) 0, 1 bis 10 Gew.-%, bezogen auf das gesamte Wasch-, Reinigungs- oder Spülmittel, (b) 0, 1 to 10 wt .-%, based on the total washing, cleaning or rinsing agent,
Hydroxycarbonsäuresalz eines chaotropen Kations. Hydroxycarboxylic acid salt of a chaotropic cation.
Fettsäureseifen wie Kokosfettsäureseifen, Ölsäureseifen oder Talgfettsäureseifen werden seit jeher in Wasch-, Reinigungs- oder Spülmitteln in Form ihrer Natrium- oder Kaliumsalze als reinigungsaktive Substanzen eingesetzt. Allerdings wirken sich diese Fettsäureseifen bekanntermaßen negativ auf das Schaumverhalten aus und werden deshalb auch als Schaumregulatoren eingesetzt.
Überraschenderweise hat sich nun gezeigt, dass das Hydroxycarbonsäuresalz eines chaotropen Kations Schaum-fördernde, insbesondere Schaum-stabilisierende, Wirkung aufweist. Außerdem sind die Salze einfach durch Umsetzung von Hydroxycarbonsäure mit einer entsprechenden Base erhältlich. Fatty acid soaps such as coconut fatty acid soaps, oleic acid soaps or tallow fatty acid soaps have always been used as detergents in washing, cleaning or rinsing agents in the form of their sodium or potassium salts. However, these fatty acid soaps are known to have a negative effect on the foaming behavior and are therefore also used as foam regulators. Surprisingly, it has now been found that the hydroxycarboxylic acid salt of a chaotropic cation has foam-promoting, in particular foam-stabilizing, action. In addition, the salts are readily available by reacting hydroxycarboxylic acid with a corresponding base.
Es ist bevorzugt, dass die Hydroxycarbonsäure ausgewählt ist aus der Gruppe der gesättigten It is preferred that the hydroxycarboxylic acid is selected from the group of saturated
Hydroxyfettsäuren, ungesättigten Hydroxyfettsäuren und Mischungen daraus. Dabei ist es insbesondere bevorzugt, dass die Hydroxycarbonsäure 12-Hydroxystearinsäure und/oder Ricinolsäure ist. Der Einsatz von Hydroxyfettsäuren als Schaum-fördernde Verbindungen ist insbesondere im Hinblick auf das Thema Nachhaltigkeit vorteilhaft, da diese auf nachwachsenden Rohstoffen basieren.

Zur Bestimmung der Schaum-fördernden Eigenschaften des Hydroxycarbonsäuresalz eines chaotropen Kations wurde das Schaumvermögen der Wasch-, Reinigungs- oder Spülmittel E2 und E3 mit dem Schaumvermögen der Wasch-, Reinigungs- oder Spülmittel V1 und V2 verglichen. Water Ad 100 Ad 100 - Ad 100 To determine the foam-promoting properties of the hydroxycarboxylic acid salt of a chaotropic cation, the foaming power of the washing, cleaning or rinsing agents E2 and E3 was compared with the foaming power of the washing, cleaning or rinsing agents V1 and V2.
Dazu wurde zunächst bei 25 °C in einem Schaumhöhenmessgerät (Contifoam der Fa. Franz Raab Datentechnik) aus einer wässrigen Lösung des jeweiligen Wasch-, Reinigungs- oder Spülmittels E2, E3, V1 oder V2 (Anwendungskonzentration: 2,3g/l) mittels Umpumpen Schaum erzeugt und das For this purpose, first at 25 ° C in a Schaumhöhenmessgerät (Contifoam Fa.

Die Ergebnisse in Tabelle 2 zeigen, dass die Wasch-, Reinigungs- oder Spülmittel E2 und E3 eine deutlich höhere Schaumstabilität aufweisen als Wasch-, Reinigungs- oder Spülmittel ohne The results in Table 2 show that the washing, cleaning or rinsing agents E2 and E3 have a significantly higher foam stability than washing, cleaning or rinsing agents without
Hydroxycarbonsäuresalz eines chaotropen Kations. Hydroxycarboxylic acid salt of a chaotropic cation.
Die verbesserte Schaumstabilität der erfindungsgemäßen Wasch-, Reinigungs- oder Spülmittel beruht vermutlich auf der Ausbildung tubulärer Strukturen in der Waschlösung. Diese tubulären Strukturen bestehen aus dem Hydroxycarbonsäuresalz eines chaotropen Kations und sind unabhängig vom parallel anwesenden Tensidsystem. Diese tubulären Strukturen erhöhen die Stabilität der Schaumlamellen und somit des gesamten Schaums.
The improved foam stability of the washing, cleaning or rinsing agents according to the invention is presumably based on the formation of tubular structures in the washing solution. These tubular structures consist of the hydroxycarboxylic acid salt of a chaotropic cation and are independent of the parallel surfactant system. These tubular structures increase the stability of the foam lamellae and thus of the entire foam.
