Description

Die vorliegende Erfindung betrifft ein Waschmittel mit la­gerstabilisiertem Bleichsystem sowie 2 bis 20 Gew% Deter­gentien und üblichen Waschhilfsstoffen, einschließlich Füllstoffen, insbesondere ein Haushaltswaschmittel für Grob-, Weiß- und Buntwäsche, wie es in Waschautomaten ver­wendet wird.The present invention relates to a detergent with a storage-stabilized bleaching system and 2 to 20% by weight of detergents and customary washing auxiliaries, including fillers, in particular a household detergent for coarse, white and colored laundry, as 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 production and the consumption of the detergent, the detergent by decomposing the bleach partially lost its washing power.

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 mit lagerstabilisiertem Bleichsystem bereitzustellen, das eine verstärkte Bleichwirkung auf das Waschgut ausübt und im Waschgut den "weichen Griff" aufrechterhält.The invention has for its object to provide a detergent with a storage-stabilized bleaching system, which exerts an increased bleaching action on the laundry and maintains the "soft handle" in the laundry.

Überraschenderweise wurde gefunden, daß ein Waschmittel mit lagerstabilisiertem Bleichmittel erhalten wird, wenn es als Builder 10 bis 50 Gew%, insbesondere 20 bis 35 Gew%, kri­stallines Schichtsilikat sowie 1 bis 5 Gew%, insbesondere 2,0 bis 3,0 Gew%, Tetraacetylethylendiamin (TAED) 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 has been found that a detergent with a storage-stabilized bleaching agent is obtained if it as a builder contains 10 to 50% by weight, in particular 20 to 35% by weight, of crystalline sheet silicate and 1 to 5% by weight, in particular 2.0 to 3.0% by weight. Contains tetraacetylethylene diamine (TAED) 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 SiX O2X+1 . Y H₂O
worin
X = 1,9 bis 4,0,
M = Na oder H,
Y = 0 bis 20
bedeuten. Ganz besonders gute Ergebnisse werden erreicht, wenn das kristalline Schichtsilikat der δ-Modifikation des Na₂Si₂O₅ entspricht.A crystalline layered silicate of the general formula has proven particularly useful
Na M Si X O 2X + 1 . Y H₂O
wherein
X = 1.9 to 4.0,
M = Na or H,
Y = 0 to 20
mean. 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;

  • 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;

Die bei der Herstellung des erfindungsgemäßen Waschmittels eingesetzten kristallinen Schichtsilikate können gemäß der DE-34 13 571 A1 hergestellt werden.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.

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) according to 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 investigated was stored in a climatic cabinet at a relative humidity of 70% at a temperature of 37 ° C. The detergent was 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 zwei handels­übliche Waschmittel auf Zeolith- und Natriumtripolyphos­ phat-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, two commercial detergents on zeolite and sodium tripolyphos phat basis included in Table 2. The bleach degradation, especially sodium percarbonate, is very large in the presence of zeolite.

In der Tabelle 3 sind die Versuchsergebnisse entsprechend der DIN 44983 für die verschiedenen Waschmittelformu­lierungen, die gemäß Gleichung I bestimmt wurden, aufge­listet.
Aus den Testwerten ist zu entnehmen, daß die Bleichmittel­wirkung gesteigert wird, wenn als Builder kristallines Schichtsilikat anstelle von Zeolith eingesetzt wird. In An­wesenheit von TAED erfolgt eine synergistisch gesteigerte Waschkraft (Bleichwirkung) des Waschmittels.Table 3 lists the test results according to DIN 44983 for the different detergent formulations which were determined in accordance with equation I.
It can be seen from the test values that the bleaching action is increased when crystalline layered silicate is used as the builder instead of zeolite. In the presence of TAED there is a synergistic increase in the washing power (bleaching effect) of the detergent.

Die Griffbeurteilung durch ein Gremium von Experten ergab einen deutlich "weicheren Griff" des Waschgutes, welches mit erfindungsgemäßen Waschmitteln gemäß den Beispielen 2 und 3 gewaschen war, gegenüber dem Waschgut, welches mit zeolithhaltigem Waschmittel gemäß den Beispielen 1 und 4 gewaschen war.
