Description

Die vorliegende Erfindung betrifft ein lagerstabilisiertes Waschmittel mit verstärkter Bleichwirkung, insbesondere ein Haushaltswaschmittel für Grob-, Weiß- und Buntwäsche, mit 2 bis 20 Gew% Detergentien und üblichen Waschhilfsstoffen, einschließlich Füllstoffen, wie es in Waschautomaten ver­wendet wird.The present invention relates to a storage-stabilized detergent with increased bleaching action, in particular a household detergent for coarse, white and colored laundry, with 2 to 20% by weight of detergents and conventional washing aids, including fillers, as is used in automatic washing machines.

Durch die zunehmende Verbreitung von Haushaltswaschautoma­ten muß das Waschmittel den geänderten Waschbedingungen an­gepaßt werden.Due to the increasing spread of household washing machines, the detergent has to be adapted to the changed washing conditions.

Moderne Waschmittel bestehen deshalb aus einer Kombination von Detergentien als waschaktive Substanzen, Bleichmitteln und die Waschkraft verstärkenden Zusätzen, den sogenannten Buildern, die einerseits die Härte der Waschlauge beseiti­gen und andererseits Ablagerungen von anorganischen Salzen auf dem Waschgut verhindern und dadurch für einen "weichen Griff" des Waschgutes nach dem Waschvorgang sorgen.Modern detergents therefore consist of a combination of detergents as washing-active substances, bleaching agents and additives that increase washing power, the so-called builders, which on the one hand remove the hardness of the washing liquor and on the other hand prevent deposits of inorganic salts on the laundry and thereby ensure a "soft touch" Provide laundry after washing.

Als hervorragende Builder gelten polymere Phosphate, insbe­sondere Natriumtripolyphosphat. Wegen der Eutrophierungsge­fahr der Flüsse und Seen durch den Phosphatgehalt in den häuslichen Abwässern wurde als Builder die Verwendung von Zeolithen vorgeschlagen.Polymeric phosphates, in particular sodium tripolyphosphate, are considered to be excellent builders. Because of the risk of eutrophication of the rivers and lakes due to the phosphate content in the domestic wastewater, the use of zeolites was proposed as a builder.

Es hat sich gezeigt, daß der Gebrauch von Zeolithen als Builder die Nachteile hat, daß das Waschgut im Verlaufe von mehreren Waschvorgängen den erwünschten "weichen Griff" verliert. Hinzu kommt, daß während der Lagerzeit, die zwi­schen der Herstellung und dem Verbrauch des Waschmittels liegt, das Waschmittel durch Zersetzung des Bleichmittels teilweise seine Waschkraft einbüßt.It has been shown that the use of zeolites as a builder has the disadvantages that the items to be washed lose the desired "soft feel" in the course of several washes. In addition, during the storage period, which lies between the manufacture and consumption of the detergent, the detergent partially loses its washing power due to the decomposition of the bleach.

In der DE-34 16 669 A1 ist deshalb vorgeschlagen worden, dem Waschmittel zusätzlich 1 bis 20 Gew% kristallines Schichtsilikat oder Alkalisilikat zuzusetzen. Hierdurch konnte ein "weicher Griff" des Waschgutes auch dann er­reicht werden, wenn als Builder Zeolithe verwendet werden; die Lagerstabilität des Waschmittels wurde jedoch hierdurch nicht beeinflußt.In DE-34 16 669 A1 it has therefore been proposed to add 1 to 20% by weight of crystalline layered silicate or alkali silicate to the detergent. As a result, a "soft grip" of the laundry could be achieved even if zeolites are used as builders; however, the storage stability of the detergent was not affected by this.

Der Erfindung liegt die Aufgabe zugrunde, ein Waschmittel bereitzustellen, das eine verbesserte Lagerstabilität und eine verstärkte Bleichwirkung hat sowie im Waschgut den "weichen Griff" aufrechterhält.The invention has for its object to provide a detergent that has an improved storage stability and an increased bleaching effect and maintains the "soft touch" in the laundry.

Überraschenderweise wurde gefunden, daß ein lagerstabili­siertes Waschmittel mit verstärkter Bleichwirkung erhalten wird, wenn es als Builder 10 bis 50 Gew%, insbesondere 20 bis 35 Gew%, kristallines Schichtsilikat und ein Bleich­mittel enthält, wobei die Bleichmittelmenge so bemessen ist, daß 0,5 bis 4 Gew%, insbesondere 1,0 bis 2,5 Gew%, waschaktiver Sauerstoff (AVOX) im Waschmittel vorliegt.Surprisingly, it was found that a storage-stabilized detergent with increased bleaching action is obtained if it contains 10 to 50% by weight, in particular 20 to 35% by weight, of crystalline layered silicate and a bleaching agent, the amount of bleaching agent being such that 0.5 to 4% by weight, in particular 1.0 to 2.5% by weight, of washing-active oxygen (AVOX) is present in the detergent.

Besonders bewährt hat sich ein kristallines Schichtsilikat der allgemeinen Formel
Na M Si₂ O₅,
worin
M = Na oder H ist.A crystalline layered silicate of the general formula has proven particularly useful
Na M Si₂ O₅,
wherein
M = Na or H.

Ganz besonders gute Ergebnisse werden erzielt, wenn das kristalline Schichtsilikat der δ -Modifikation des Na₂Si₂O₅ entspricht.Particularly good results are achieved if the crystalline layered silicate corresponds to the δ modification of Na₂Si₂O₅.

Das erfindungsgemäße Waschmittel kann weiterhin bevorzugt und wahlweise dadurch gekennzeichnet sein, daß

  • a) das kristalline Schichtsilikat einen Teilchendurchmesser von 0,01 bis 1000 µm, insbesondere von 1 bis 20 µm, hat;
  • b) das kristalline Schichtsilikat eine Ionenaustauschkapa­zität von 400 bis 1200 mmol Na⁺/100 g wasserfreie Substanz hat;
  • c) das Bleichmittel Natriumperborat-Tetrahydrat, Natrium­perborat-Monohydrat und/oder Natriumpercarbonat ist;
  • d) es anorganische und/oder organische Phosphate, Borate, Zitrate, Gluconate, Nitrilotriessigsäure (NTA) und/oder Iminodiacetate als zusätzliche Builder in Mengen von bis zu 20 Gew% enthält;
  • e) es aus Agglomeratteilchen mit einer Teilchengröße im Bereich von 0,25 bis 2,5 mm besteht und durch einen Sprühnebelmischprozeß erhalten wurde;
  • f) es als Detergent Alkalisalze von Alkylbenzolsulfonaten, höheren Alkylsulfonaten und/oder höheren Fettalkohol­polyethoxylatsulfaten, insbesondere mit Alkylresten mit durchschnittlich 10 bis 18 C-Atomen in der Alkylgruppe, enthält;
  • g) es als Waschhilfsstoff Carboxymethylcellulose, Carboxy­methylstärke und/oder Methylcellulose in Mengen von bis zu 10 Gew% enthält.
The detergent according to the invention can also be preferred and optionally characterized in that
  • a) the crystalline layered silicate has a particle diameter of from 0.01 to 1000 μm, in particular from 1 to 20 μm;
  • b) the crystalline layered silicate has an ion exchange capacity of 400 to 1200 mmol Na⁺ / 100 g of anhydrous substance;
  • c) the bleaching agent is sodium perborate tetrahydrate, sodium perborate monohydrate and / or sodium percarbonate;
  • d) it contains inorganic and / or organic phosphates, borates, citrates, gluconates, nitrilotriacetic acid (NTA) and / or iminodiacetates as additional builders in amounts of up to 20% by weight;
  • e) it consists of agglomerate particles with a particle size in the range from 0.25 to 2.5 mm and was obtained by a spray mixing process;
  • f) it contains, as detergent, alkali metal salts of alkylbenzenesulfonates, higher alkylsulfonates and / or higher fatty alcohol polyethoxylate sulfates, in particular with alkyl radicals with an average of 10 to 18 carbon atoms in the alkyl group;
  • g) it contains carboxymethyl cellulose, carboxymethyl starch and / or methyl cellulose in amounts of up to 10% by weight as washing auxiliary.

Die bei der Herstellung des erfindungsgemäßen Waschmittels eingesetzten kristallinen Schichtsilikate können gemäß der DE-34 13 571 A1 hergestellt werden. Obwohl alle in der DE-34 13 571 A1 aufgeführten kristallinen Schichtsilikate in das erfindungsgemäße Waschmittel eingesetzt werden kön­nen, hat es sich gezeigt, daß dem δ -Na₂Si₂O₅ der Vorzug dann zu geben ist, wenn es auf eine erhöhte Bleichwirkung beim Waschvorgang ankommt.The crystalline sheet silicates used in the preparation of the detergent according to the invention can be prepared in accordance with DE-34 13 571 A1. Although everyone in the DE-34 13 571 A1 listed crystalline sheet silicates can be used in the detergent according to the invention, it has been shown that the δ -Na₂Si₂O₅ is to be given preference when it comes to an increased bleaching effect during the washing process.

Die Bestimmung des waschaktiven Sauerstoffs (AVOX) des Bleichmittels als auch des Waschmittels erfolgte nach der Vorschrift von Dr. E. Heinerth, Tenside 2 (1965) 180. Das untersuchte Natriumperborat-Tetrahydrat (NaBO₃ . 4 H₂O) hatte eine AVOX-Zahl von 10 Gew%; das Natriumperborat-Mono­hydrat (NaBO₃ . H₂O) hatte eine AVOX-Zahl von 15 Gew%; das Natriumpercarbonat (2 Na₂CO₃ . 3 H₂O₂) hatte eine AVOX-Zahl von 13,5 Gew%.The determination of the wash-active oxygen (AVOX) of the bleach and the detergent was carried out according to the instructions of Dr. E. Heinerth, Tenside 2 (1965) 180. The sodium perborate tetrahydrate (NaBO₃. 4 H₂O) examined had an AVOX number of 10% by weight; the sodium perborate monohydrate (NaBO₃. H₂O) had an AVOX number of 15% by weight; the sodium percarbonate (2 Na₂CO₃. 3 H₂O₂) had an AVOX number of 13.5% by weight.

Die Waschkraft (Bleichwirkung) des Waschmittels wurde als Weißgrad der Testgewebe (WFK-Polyester/Baumwolle mit Tee-­Anschmutzung, Order-Code 20 G) gemäß der DIN 44983 er­mittelt.The washing power (bleaching effect) of the detergent was determined as the whiteness of the test fabrics (WFK polyester / cotton with tea soiling, order code 20 G) in accordance with DIN 44983.

Die Waschkraft (Bleichwirkung) der Waschflotte wurde nach der Differenzmethode ermittelt, die sich aus der Gleichung I
% WK = % WGg - % WGb
ergibt. Es bedeutet:
% WK = % Waschkraft (Bleichwirkung)
% WGg = % Weißgrad des gewaschenen Stoffes % WGb = % Weißgrad des ungewaschenen Stoffes.The washing power (bleaching effect) of the washing liquor was determined using the difference method, which is derived from equation I
% WK =% WG g -% WG b
results. It means:
% WK =% washing power (bleaching effect)
% WG g =% whiteness of the washed fabric% WG b =% whiteness of the unwashed fabric.

Die Lagerteste wurden nach folgenden forcierten Testbe­dingungen gemacht:
Im Klimaschrank wurde das zu untersuchende Waschmittel bei einer relativen Luftfeuchtigkeit von 70 bei einer Tempe­ratur von 37°C gelagert. Das Waschmittel war dabei in einem Wachs-Karton verpackt. Die Wasserdampfdurchlässigkeit der Verpackung betrug 0,4 g/m² . h.The storage tests were carried out according to the following forced test conditions:
The detergent to be examined was stored in a climatic cabinet at a relative humidity of 70 and a temperature of 37 ° C. The detergent was in packed in a wax box. The water vapor permeability of the packaging was 0.4 g / m². H.

In der Tabelle 1 sind die getesteten Waschmittelformu­lierungen aufgelistet.The detergent formulations tested are listed in Table 1.

In der Tabelle 2 sind die Abbauwerte des Bleichmittels in Abhängigkeit von der Zeit nach den forcierten Lagertestbe­dingungen zusammengestellt. Zusätzlich wurden 2 handelsüb­liche Waschmittel auf Zeolith- und Natriumtripolyphos­phat-Basis in die Tabelle 2 aufgenommen. Der Bleichmittel­abbau, insbesondere von Natriumpercarbonat, ist in Anwesen­heit von Zeolith sehr groß.Table 2 shows the degradation values of the bleaching agent as a function of time after the forced storage test conditions. In addition, 2 commercial detergents based on zeolite and sodium tripolyphosphate were included in Table 2. The bleach degradation, especially of sodium percarbonate, is very large in the presence of zeolite.

Waschergebnisse:Washing results:

Entsprechend der DIN 44983 wurden die Waschmittelformu­lierungen 2 und 4 getestet und nach Gleichung I berechnet. Die Waschkraft (Bleichwirkung) des Waschmittels 2 betrug 30,0 %; die des erfindungsgemäßen Waschmittels 4 betrug 36,5 %.In accordance with DIN 44983, detergent formulations 2 and 4 were tested and calculated according to equation I. The washing power (bleaching effect) of detergent 2 was 30.0%; that of the detergent 4 according to the invention was 36.5%.

Die Griffbeurteilung durch ein Gremium von Experten ergab einen deutlich "weicheren Griff" des Waschgutes, welches mit dem erfindungsgemäßen Waschmittel 4 gewaschen war, ge­genüber dem Waschgut, welches mit dem zeolithhaltigen Waschmittel 2 gewaschen war.
