Description
Die Erfindung betrifft ein flüssiges Wasch- oder Reinigungsmittel mit anionischen und nichtionischen Tensiden. Die Erfindung betrifft auch eine wasserlösliche Verpackung, umfassend ein solches flüssiges Wasch- oder Reinigungsmittel.The invention relates to a liquid detergent or cleaning agent with anionic and nonionic surfactants. The invention also relates to a water-soluble packaging comprising such a liquid detergent or cleaning agent.
Immer häufiger werden empfindliche Textilien, wie zum Beispiel Seide oder Mikrofaser, zu Kleidungsstücken verarbeitet, die nur bei 30 oder 40 °C gewaschen werden können. Weiterhin liegt energiesparendes Waschen bei niedrigen Waschtemperaturen im Trend. Allerdings nimmt die Leistung von Waschmitteln an Fett-haltigen Anschmutzungen bei Erniedrigung der Waschtemperaturen ab. Eine Vorbehandlung der Fett-haltigen Anschmutzungen wird von vielen Verbrauchern als lästig angesehen.Increasingly, delicate textiles, such as silk or microfiber, are processed into garments that can only be washed at 30 or 40 ° C. Furthermore, energy-saving washing at low wash temperatures is the trend. However, the performance of detergents on fatty soils decreases with decreasing wash temperatures. Pretreatment of greasy soils is considered troublesome by many consumers.

Aus der Druckschrift
Es besteht aber weiterhin Bedarf, die Reinigungsleistung von Wasch- oder Reinigungsmitteln, insbesondere an Fett-haltigen Anschmutzungen, zu verbessern.However, there is still a need to improve the cleaning performance of detergents or cleaners, especially on soils containing grease.
Wasch- oder Reinigungsmittel sind heute für den Verbraucher in vielfältigen Angebotsformen erhältlich. Neben Pulvern und Granulaten umfasst dieses Angebot beispielsweise auch Flüssigkeiten, Gele oder Portionspackungen (Tabletten oder gefüllte Beutel).Detergents or cleaners are now available to the consumer in a variety of forms. In addition to powders and granules, this offer includes, for example, liquids, gels or sachets (tablets or filled pouches).
Insbesondere Portionspackungen mit flüssigen Wasch- oder Reinigungsmitteln werden immer beliebter, erfüllen sie einerseits den Wunsch des Verbrauchers nach vereinfachter Dosierung und andererseits bevorzugen immer mehr Verbraucher flüssige Wasch- oder Reinigungsmittel.In particular, portion packs containing liquid detergents or cleaning agents are becoming increasingly popular, fulfilling, on the one hand, the consumer's desire for simplified dosing and, on the other hand, more and more consumers prefering liquid detergents or cleaners.
Bei der Formulierung von flüssigen Wasch- oder Reinigungsmitteln zur Verpackung in wasserlöslichen Beuteln muss insbesondere darauf geachtet werden, dass die Inhaltsstoffe des Wasch- oder Reinigungsmittels die wasserlösliche Umhüllung des Beutels nicht schon vor ihrem Einsatz auf- oder anlösen und so zu unerwünschten Leckagen führen.When formulating liquid detergents or cleaners for packaging in water-soluble bags, particular care must be taken to ensure that the ingredients of the washing or cleaning agent do not dissolve or dissolve the water-soluble envelope of the bag before they are used and thus lead to undesirable leaks.
Entsprechend war es eine Aufgabe der vorliegenden Erfindung, ein flüssiges Wasch- oder Reinigungsmittel mit erhöhter Reinigungsleistung, insbesondere an Fett-haltigen Anschmutzungen, bereit zu stellen, welches auch zur Verpackung in einer wasserlöslichen Umhüllung geeignet ist.Accordingly, it was an object of the present invention to provide a liquid detergent or cleaning agent with increased cleaning performance, especially on soils containing grease, which is also suitable for packaging in a water-soluble coating.
Diese Aufgabe wird gelöst durch ein flüssiges Wasch- oder Reinigungsmittel, umfassend
- a) ein mit einem Amin neutralisiertes anionisches Tensid,
- b) einen alkoxylierten Oxo-Alkohol, ausgewählt aus C13-15-Oxo-Alkoholen mit 8 EO und
- c) bis zu 10 Gew.-%, bezogen auf das gesamte Wasch- oder Reinigungsmittel, Wasser.
- a) an anionic surfactant neutralized with an amine,
- b) an alkoxylated oxo alcohol selected from C 13-15 oxo-alcohols with 8 EO and
- c) up to 10 wt .-%, based on the total washing or cleaning agent, water.
Es hat sich überraschenderweise gezeigt, dass die Verwendung von besagten Oxo-Alkoholen als nichtionische Tenside zu flüssigen Wasch- oder Reinigungsmitteln mit erhöhter Reinigungsleistung, insbesondere an Fett-haltigen Anschmutzungen, führt.It has surprisingly been found that the use of said oxo alcohols as nonionic surfactants to liquid detergents or cleaning agents with increased cleaning performance, especially on fat-containing soils leads.
In einer bevorzugten Ausführungsform der Erfindung ist das Amin ausgewählt ist aus der Gruppe bestehend aus Cholin, Triethylamin, Monoethanolamin, Diethanolamin, Triethanolamin, Methylethylamin und Mischungen daraus.In a preferred embodiment of the invention, the amine is selected from the group consisting of choline, triethylamine, monoethanolamine, diethanolamine, triethanolamine, methylethylamine and mixtures thereof.
Die Neutralisation mit Aminen führt, anders als bei Basen wie NaOH oder KOH, nicht zu Bildung von Wasser. Somit können wasserarme Wasch- oder Reinigungsmittel hergestellt werden, die direkt für die Verwendung in wasserlöslichen Beuteln geeignet sind.The neutralization with amines, unlike bases such as NaOH or KOH, does not lead to the formation of water. Thus, low-water detergents or cleaners can be prepared which are directly suitable for use in water-soluble bags.
Es ist insbesondere bevorzugt, dass das neutralisierte anionische Tensid ausgewählt ist aus der Gruppe bestehend aus neutralisierten Alkylbenzolsulfonsäuren, neutralisierten Olefinsulfonsäuren, neutralisierten C12-18-Alkansulfonsäuren, neutralisierten Schwefelsäuremonoestern mit Fettalkoholen, neutralisierten Fettsäuren, neutralisierten Schwefelsäuremonoestern mit ethoxylierten Fettalkoholen und Mischungen daraus. Diese neutralisierten anionischen Tenside weisen eine hohe Reinigungsleistung an einer Vielzahl an Anschmutzungen auf.It is particularly preferred that the neutralized anionic surfactant is selected from the group consisting of neutralized alkylbenzenesulfonic acids, neutralized olefinic sulfonic acids, neutralized C 12-18 alkanesulfonic acids, neutralized sulfuric acid monoesters with fatty alcohols, neutralized fatty acids, neutralized sulfuric acid monoesters with ethoxylated fatty alcohols, and mixtures thereof. These neutralized anionic surfactants have a high cleaning performance on a variety of stains.
Eine besonders hohe Reinigungsleistung an Fett-haltigen Anschmutzungen wird bei Einsatz von C13-15-Oxo-Alkoholen mit 8 EO in den flüssigen Wasch- oder Reinigungsmitteln erhalten.A particularly high cleaning performance of greasy soils is obtained when using C 13-15 oxo-alcohols with 8 EO in the liquid detergents or cleaners.
Die Erfindung betrifft auch eine wasserlösliche Verpackung, die ein flüssiges Wasch- oder Reinigungsmittel und eine wasserlösliche Umhüllung enthält, wobei das flüssige Wasch- oder Reinigungsmittel
- a) ein mit einem Amin neutralisiertes anionisches Tensid,
- b) einen alkoxylierten Oxo-Alkohol ausgewählt aus C13-15-Oxo-Alkoholen mit 8 EO und
- c) bis zu 10 Gew.-%, bezogen auf das gesamte Wasch- oder Reinigungsmittel, Wasser enthält.
