Description

Die Erfindung betrifft ein wäßriges, Buildersalze enthaltendes Flüssigwaschmittel, das Wasserstoffperoxid als bleichendes Agens enthält und sich durch eine hohe Lagerstabilität sowie eine leichte Dosierbarkeit auszeichnet.The invention relates to an aqueous liquid detergent containing builder salts, which contains hydrogen peroxide as a bleaching agent and is distinguished by high storage stability and easy meterability.

Es sind sowohl nichtwäßrige als auch wäßrige Flüssigwaschmittel bekannt, die bleichende Perverbindungen enthalten. In nichtwäß­rigen Mitteln ist die Stabilisierung der Perverbindungen meist unproblematisch. Dafür bereitet jedoch die Stabilisierung der Mittel gegen Entmischen vielfach Schwierigkeiten. Man behilft sich meist damit, daß man die Mittel auf eine hohe Viskosität einstellt und die Inhaltsstoffe in einem aufwendigen Mahlprozeß mittels Kolloidmühlen auf eine sehr kleine Korngröße vermahlt. Vielfach müssen noch Sedimentationsstabilisatoren zugesetzt werden. Nach­teilig ist ferner, daß vielfach größere Anteile an brennbaren or­ganischen Lösungsmitteln zugesetzt werden müssen. Mittel der ge­nannten Art sind beispielsweise in DE 12 79 878 (GB 12 05 711), DE 22 33 771 (US 38 50 831), DE 28 25 218 (US 43 16 812) und EP 30 086 beschrieben.Both non-aqueous and aqueous liquid detergents containing bleaching per-compounds are known. In non-aqueous agents, the stabilization of the per-compounds is usually not a problem. However, the stabilization of the anti-segregation agents often presents difficulties. One usually helps by adjusting the agents to a high viscosity and grinding the ingredients to a very small grain size in a complex grinding process using colloid mills. In many cases sedimentation stabilizers still have to be added. Another disadvantage is that often larger amounts of flammable organic solvents have to be added. Means of the type mentioned are described for example in DE 12 79 878 (GB 12 05 711), DE 22 33 771 (US 38 50 831), DE 28 25 218 (US 43 16 812) and EP 30 086.

In wäßrigen Flüssigwaschmitteln, in denen die Inhaltsstoffe gelöst sind und daher gegen Phasentrennung im allgemeinen beständiger sind, bereitet die Stabilisierung von sauerstoffhaltigen Bleich­mitteln erhebliche Schwierigkeiten. So wird in DE 10 80 722 vorgeschlagen, den Mitteln hochkondensierte Phosphate zuzusetzen und sie auf einen pH-Wert von 6 bis 6,5 einzustellen. Im sauren Bereich ist die Waschkraft jedoch vergleichsweise geringer als im alkalischen. Außerdem sind die Mittel aufgrund ihres hohen Anteils an nichtionischen Tensiden pastös und somit nicht, wie in Ver­braucherkreisen bevorzugt, mit Meßbechern dosierbar. Die in DE 15 67 583 (US 36 58 712) beschriebenen Mittel enthalten ein spezi­elles vernetztes Polymerisat als Stabilisator, das die Mittel ebenfalls sehr dickflüssig und somit schlecht dosierbar macht. In EP 38 101 wird schließlich vorgeschlagen, die Bleichmittelkörner einzukapseln und sie in dieser Form in dem Mittel zu suspendieren. Über die Art des Kapselmaterials, das logischerweise im wäßrigen Vorratskonzentrat beständig bzw. unlöslich, in der wäßrigen Waschlauge hingegen unbeständig bzw. leicht löslich sein muß, finden sich in dem Dokument keine Angaben.In aqueous liquid detergents in which the ingredients are dissolved and are therefore generally more resistant to phase separation, the stabilization of oxygen-containing bleaching agents presents considerable difficulties. So in DE 10 80 722 proposed adding highly condensed phosphates to the compositions and adjusting them to a pH of 6 to 6.5. In the acidic range, however, the washing power is comparatively lower than in the alkaline range. In addition, because of their high proportion of nonionic surfactants, the compositions are pasty and therefore cannot be metered with measuring cups, as is preferred in consumer circles. The agents described in DE 15 67 583 (US 36 58 712) contain a special cross-linked polymer as a stabilizer, which also makes the agents very viscous and therefore difficult to dose. Finally, EP 38 101 proposes encapsulating the bleaching agent granules and suspending them in the agent in this form. There is no information in the document about the nature of the capsule material, which logically has to be stable or insoluble in the aqueous stock concentrate, but has to be inconsistent or easily soluble in the aqueous wash liquor.

Die aufgezeigten Probleme werden durch die vorliegende Erfindung gelöst.The problems outlined are solved by the present invention.

Gegenstand der Erfindung ist ein bleichendes Flüssigwaschmittel enthaltend

  • (A) 5 bis 15 Gew.-% eines linearen Alkylbenzolsulfonats mit 9 bis 13 C-Atomen in der Alkylkette in Form des Natrium- oder Kali­umsalzes,
  • (B) 1 bis 5 Gew.-% eines Aminoxids, enthaltend einen linearen C₁₂₋₁₆-Alkylrest,
  • (C) 1 bis 6 Gew.-% einer von C₁₂₋₁₈-Fettsäuren abgeleiteten Seife in Form des Natrium- oder Kaliumsalzes,
  • (D) 10 bis 22 Gew.-% Kaliumpyrophosphat,
  • (E) 2 bis 12 Gew.-% eines Hydrotrops,
  • (F) 0,5 bis 5 Gew.-% Wasserstoffperoxid,
  • (G) 45 bis 60 Gew.-% Wasser.
The invention relates to a bleaching liquid detergent containing
  • (A) 5 to 15% by weight of a linear alkylbenzenesulfonate with 9 to 13 C atoms in the alkyl chain in the form of the sodium or potassium salt,
  • (B) 1 to 5% by weight of an amine oxide containing a linear C₁₂₋₁₆ alkyl radical,
  • (C) 1 to 6% by weight of a soap derived from C₁₂₋₁₈ fatty acids in the form of the sodium or potassium salt,
  • (D) 10 to 22% by weight of potassium pyrophosphate,
  • (E) 2 to 12% by weight of a hydrotrope,
  • (F) 0.5 to 5% by weight of hydrogen peroxide,
  • (G) 45 to 60 wt% water.

Das Alkylbenzolsulfonat liegt vorzugsweise als Natriumsalz vor. Sein Anteil beträgt vorzugsweise 7 bis 12 Gew.-%.The alkylbenzenesulfonate is preferably in the form of the sodium salt. Its proportion is preferably 7 to 12% by weight.

Geeignete Aminoxide sind z. B. Dodecyl-dimethyl-aminoxid, Tride­cyl-dimethyl-aminoxid, Tetradecyl-dimethyl-aminoxid, Pentadecyl-­dimethyl-aminoxid und Hexadecyl-dimethyl-aminoxid sowie deren Ge­mische. Vorzugsweise beträgt ihr Anteil 2 bis 5 Gew.-%.Suitable amine oxides are e.g. B. dodecyldimethylamine oxide, tridecyldimethylamine oxide, tetradecyldimethylamine oxide, pentadecyldimethylamine oxide and hexadecyldimethylamine oxide and mixtures thereof. Their proportion is preferably 2 to 5% by weight.

Als Seifen eignen sich vorzugsweise solche aus natürlichen Fett­säuregemischen, wie Cocos- oder Palmkernfettsäure. Die Fettsäuren mit 10 und weniger C-Atomen werden zuvor auf einen Anteil von we­niger als 5 Gew.-%, vorzugsweise auf weniger als 3 Gew.-% (bezogen auf Seife) abgetrennt. Ebenso empfiehlt es sich, die Stearinsäure auf einen Stearatgehalt unter 20 Gew.-%, vorzugsweise unter 15 Gew.-% (bezogen auf Seife) abzutrennen. Der Anteil an ungesät­tigten fettsauren Seifen, wie Oleat, beträgt zweckmäßigerweise ebenfalls unter 10 %, bezogen auf Seife. Die Seifen liegen bevor­zugt als Natriumsalze vor, wobei deren Anteil bevorzugt 2 bis 5 Gew.-% beträgt.Suitable soaps are preferably those from natural fatty acid mixtures, such as coconut or palm kernel fatty acid. The fatty acids with 10 and fewer carbon atoms are previously separated off in a proportion of less than 5% by weight, preferably less than 3% by weight (based on soap). It is also advisable to separate the stearic acid to a stearate content below 20% by weight, preferably below 15% by weight (based on soap). The proportion of unsaturated fatty acid soaps, such as oleate, is advantageously also less than 10%, based on soap. The soaps are preferably in the form of sodium salts, the proportion of which is preferably 2 to 5% by weight.

Der Anteil des Kaliumpyrophosphats, das bevorzugt als Tetraka­liumpyrophosphat eingesetzt wird, beträgt vorzugsweise 15 bis 21 Gew.-%. Höhere Anteile, d. h. solche bis 25 Gew.-%, sind zwar grundsätzlich möglich, aus Gründen der Phosphatbeschränkungen im Abwasser jedoch weniger empfehlenswert.The proportion of potassium pyrophosphate, which is preferably used as tetrapotassium pyrophosphate, is preferably 15 to 21% by weight. Higher proportions, i.e. H. those up to 25% by weight are possible in principle, but are less recommendable for reasons of phosphate restrictions in waste water.

Als Hydrotrop eignen sich Toluolsulfonat, Xylolsulfonat und Cumolsulfonat, jeweils in Form der Natriumsalze. Vorzugsweise be­trägt ihr Anteil 5 bis 10 Gew.-%.Suitable hydrotropes are toluenesulfonate, xylene sulfonate and cumene sulfonate, each in the form of the sodium salts. Their proportion is preferably 5 to 10% by weight.

Das Wasserstoffperoxid ist als 100%iges H₂O₂ berechnet. Sein An­teil beträgt vorzugsweise 1 bis 4 Gew.-%.The hydrogen peroxide is calculated as 100% H₂O₂. Its proportion is preferably 1 to 4% by weight.

Das Wasser soll entionisiert und insbesondere frei von Schwerme­tallionen sein. Sein Anteil beträgt vorzugsweise 50 bis 57 Gew.-%. Zusätzlich können in geringer Menge solche Bestandteile anwesend sein, die gegen Oxidation unempfindlich sind, wie Farbstoffe oder Trübungsmittel. Zusätzliche Stabilisierungsmittel sind nicht er­forderlich, da die Mittel bereits von sich aus eine überraschend hohe Lagerstabilität aufweisen. Immerhin können geringe Anteile, d. h. maximal 0,5 bis 1 Gew.-%, an oxidationsunempfindlichen se­questrierend wirkenden Stabilisatoren anwesend sein, wie 1-Hy­droxyethan-1,1-diphoshponsäure, Ethylendiamin-tetra-(methylen­phosphonsäure und Diethylentriamin-penta-(methylenphosphonsäure), jeweils in Form des Na- oder K-Salzes.The water should be deionized and in particular free of heavy metal ions. Its proportion is preferably 50 to 57% by weight. In addition, small amounts of those constituents which are insensitive to oxidation, such as dyes or opacifiers, can be present. Additional stabilizing agents are not required since the agents themselves have a surprisingly high storage stability. After all, small proportions, i.e. H. a maximum of 0.5 to 1% by weight of oxidation-insensitive sequestering stabilizers, such as 1-hydroxyethane-1,1-diphoshonic acid, ethylenediamine-tetra- (methylenephosphonic acid and diethylenetriamine-penta- (methylenephosphonic acid), in each case in the form of Na - or K salt.

Die Mittel sind ungeachtet ihrer alkalischen Reaktion sehr lagerstabil. Der Verlust an Aktivsauerstoff beträgt auch nach mehrmonatiger Lagerung bei Raumtemperatur (20 - 25 °C) weniger als 1 %. Bei der Anwendung zeichnen sie sich durch eine hohe Wasch- und Bleichwirkung insbesondere gegenüber farbigen Anschmutzungen aus.Regardless of their alkaline reaction, the agents are very stable in storage. The loss of active oxygen is less than 1% even after storage for several months at room temperature (20 - 25 ° C). When used, they are characterized by a high washing and bleaching effect, especially in relation to colored stains.
