Description

Die Erfindung betrifft ein in einer wasserlöslichen Umhüllung verpacktes, hochkonzentriertes flüssiges Wasch- oder Reinigungsmittel mit anionischen und nichtionischen Tensiden.The invention relates to a packed in a water-soluble wrapper, highly concentrated liquid detergent or cleaning agent with anionic and nonionic surfactants.

Im Zuge des steigenden Umweltbewusstseins bei Industrie und Verbrauchern ist es wünschenswert, möglichst hochkonzentrierte Wasch- oder Reinigungsmittel zu formulieren, die in kleineren Verpackungen angeboten werden können und so nach ihrer Verwendung weniger Abfall hinterlassen.In the context of increasing environmental awareness among industry and consumers, it is desirable to formulate highly concentrated detergents or cleaning agents that can be offered in smaller packages and thus leave less waste after their use.

Aus der WO 2010/019841 A2 ist beispielsweise ein ultrakonzeetriertes flüssiges Wasch- oder Reinigungsmittel bekannt, welches (a) 25 bis 60 Gew.-% nichtionisches Tensid, (b) 5 bis 30 Gew.-% anionisches Tensid, (c) 0.5 bis 18 Gew.-% einer Kaltwasser-Dispergierhilfe und (d) bis 60 Gew.-% Wasser enthält.From the WO 2010/019841 A2 For example, an ultraconcentrated liquid detergent or cleaning composition is known which comprises (a) from 25 to 60% by weight of nonionic surfactant, (b) from 5 to 30% by weight of anionic surfactant, (c) from 0.5 to 18% by weight of cold water Dispersing aid and (d) contains up to 60% by weight of water.

Aus der Druckschrift EP 1 516 917 A1 sind in einer wasserlöslichen Umhüllung verpackte Flüssigwaschmittel bekannt, die 5 bis 80 Gew.-% Tensid, 20 bis 50 Gew.-% Fettsäure (i.e. Fettsäure und deren Seife),1 bis 15 Gew.-% nicht-wässriges Lösemittel und weniger als 10 Gew.-% Wasser enthalten, wobei das Molverhältnis der Fettsäure zur Fettsäureseife im Bereich von 5 : 1 bis 1 : 5 liegt.From the publication EP 1 516 917 A1 For example, liquid detergent packaged in a water-soluble wrapper comprising 5 to 80% by weight of surfactant, 20 to 50% by weight of fatty acid (ie fatty acid and its soap), 1 to 15% by weight of non-aqueous solvent and less than 10% Wt .-% water, wherein the molar ratio of the fatty acid to the fatty acid soap in the range of 5: 1 to 1: 5.

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). 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. Auch hier ist es wünschenswert, möglichst hochkonzentrierte Wasch- oder Reinigungsmittel zu verwenden.Detergents or cleaning agents 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 bags). 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. Again, it is desirable to use highly concentrated detergents or cleaning agents.

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.

Auch kann es bei hochkonzentrierten Wasch- oder Reinigungsmittel Probleme mit der Stabilität, insbesondere mit der Stabilität des Tensidsystems, geben. Hochkonzentrierte Wasch- oder Reinigungsmittel (> 35 Gew.-% Tensid) mit einem auf Stabilität optimierten Tensidsystem mit hohen Mengen weisen gelegentlich Defizite in der Reinigungsleistung auf.Also, with highly concentrated detergents or cleaning agents, there may be problems with the stability, in particular with the stability of the surfactant system. Highly concentrated detergents or cleaning agents (> 35% by weight of surfactant) with a stability-optimized surfactant system with high amounts occasionally have deficits in the cleaning performance.

Entsprechend war es eine Aufgabe der vorliegenden Erfindung, ein stabiles, hochkonzentriertes flüssiges Wasch- oder Reinigungsmittel mit guter Reinigungsleistung 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 stable, highly concentrated liquid washing or cleaning agent with good cleaning performance, which is also suitable for packaging in a water-soluble casing.

Diese Aufgabe wird gelöst durch ein flüssiges Wasch- oder Reinigungsmittel enthaltend:

  1. a) 18 bis 35 Gew.-%, bezogen auf das gesamte Wasch- oder Reinigungsmittel, anionisches Tensid vom Sulfonat-Typ ausgewählt aus der Gruppe bestehend aus C9-13-Alkylbenzolsulfonaten, Olefinsulfonaten, sulfonierten Estoliden, C12-18-Alkansulfonaten und Mischungen daraus,
  2. b) 15 bis 25 Gew.-%, bezogen auf das gesamte Wasch- oder Reinigungsmittel, nichtionisches Tensid ausgewählt aus der Gruppe bestehend aus alkoxylierten Fettalkoholen, alkoxylierten Oxo-Alkoholen, Alkylpolyglycosiden und Mischungen daraus,
  3. c) 2 bis 15 Gew.-%, bezogen auf das gesamte Wasch- oder Reinigungsmittel, anionisches Tensid vom Sulfat-Typ ausgewählt aus der Gruppe bestehend aus Fettalkoholsulfaten, Fettalkoholethersulfaten und Mischungen daraus und
  4. d) 0,5 bis 20 Gew.-%, bezogen auf das gesamte Wasch- oder Reinigungsmittel, Fettsäure und/oder Fettsäureseife.
This object is achieved by a liquid washing or cleaning agent comprising:
  1. a) 18 to 35 wt .-%, based on the total washing or cleaning agent, anionic surfactant sulfonate type selected from the group consisting of C 9-13 alkyl benzene sulfonates, olefin sulfonates, sulfonated estolides, C 12-18 alkanesulfonates and Mixtures thereof,
  2. b) from 15 to 25% by weight, based on the total washing or cleaning agent, of nonionic surfactant selected from the group consisting of alkoxylated fatty alcohols, alkoxylated oxo alcohols, alkylpolyglycosides and mixtures thereof,
  3. c) 2 to 15 wt .-%, based on the total washing or cleaning agent, anionic surfactant of the sulfate type selected from the group consisting of fatty alcohol sulfates, fatty alcohol ether sulfates and mixtures thereof and
  4. d) 0.5 to 20 wt .-%, based on the total washing or cleaning agent, fatty acid and / or fatty acid soap.

das dadurch gekennzeichnet ist, dass das Wasch- oder Reinigungsmittel in einer wasserlöslichen Umhüllung verpackt vorliegt und der Gehalt an Wasser weniger als 10 Gew.-%, bezogen auf das gesamte flüssige Wasch- oder Reinigungsmittel, beträgt.which is characterized in that the washing or cleaning agent is packaged in a water-soluble wrapper and the content of water is less than 10 wt .-%, based on the total liquid detergent or cleaning agent.

Es hat sich überraschenderweise gezeigt, dass mit Hilfe des ausgewählten hochkonzentrierten Tensidsystems ein phasenstabiles Wasch- oder Reinigungsmittel mit guter Reinigungsleistung erhalten werden kann.It has surprisingly been found that with the help of the selected highly concentrated surfactant system, a phase-stable detergent or cleaning agent can be obtained with good cleaning performance.

Das Wasch- oder Reinigungsmittel weist eine besonders gute Reinigungsleistung und gutes Schaumverhalten auf, wenn das anionische Tensid vom Sulfonat-Typ ein C9-13-Alkylbenzolsulfonat ist.The washing or cleaning agent has a particularly good cleaning performance and good foaming behavior when the sulfonate anionic surfactant is a C 9-13 -alkylbenzenesulfonate.

Es ist bevorzugt, dass das Verhältnis anionisches Tensid vom Sulfonat-Typ zu nichtionischem Tensid von 1,25 : 1 bis 1 : 1,25 beträgt. Ebenso ist es bevorzugt, dass das Verhältnis anionisches Tensid vom Sulfonat-Typ zu anionischem Tensid vom Sulfat-Typ größer 2 : 1 ist und/oder dass das Verhältnis nichtionisches Tensid zu anionischem Tensid vom Sulfat-Typ größer 2: 1 ist.It is preferred that the ratio of anionic surfactant of the sulfonate type to nonionic surfactant is from 1.25: 1 to 1: 1.25. It is also preferred that the ratio of sulfonate anionic surfactant to sulfate type anionic surfactant is greater than 2: 1 and / or that the ratio of nonionic surfactant to sulfate type anionic surfactant be greater than 2: 1.
